concerns (commands, approval flow, fleet routing, conversation memory) +- Fix approach: Split into submodules: `command_handler.rs`, `approval_handler.rs`, `fleet_handler.rs`, `conversation_handler.rs`. Keep `mod.rs` as coordinator only. + +**Large Executor Files:** +- Issue: AgentFlow executor (1,713 lines) and Agent executor (1,646 lines) approaching single-responsibility limits +- Files: `crates/aof-runtime/src/executor/agentflow_executor.rs`, `crates/aof-runtime/src/executor/agent_executor.rs` +- Impact: Complex error handling paths, difficult to test individual branches, cognitive load for maintainers +- Fix approach: Extract node execution logic into separate module, consolidate error handling patterns, add integration tests for complex flows + +**Excessive unwrap() Usage:** +- Issue: 883 unwrap() calls across codebase - high panic risk in production +- Files: Widespread across `crates/` +- Impact: Any unwrap() can crash agent execution without graceful error recovery +- Fix approach: Audit high-traffic paths (runtime, executor, handler) first. Replace with `.map_err()` or `?` operator. Use `.expect()` only with specific panic messages in truly unreachable code paths. + +**Multiple Arc in Fleet and Handler:** +- Issue: 85+ combined uses of Arc and Arc for state management (FleetCoordinator, TriggerHandler) +- Files: `crates/aof-runtime/src/fleet/mod.rs`, `crates/aof-triggers/src/handler/mod.rs` +- Impact: Potential deadlock risk with nested lock acquisition, performance bottleneck under concurrent load +- Fix approach: Use DashMap where possible (already used in TriggerHandler for maps). Consider immutable state patterns or message-based concurrency for frequently-locked structures. + +**Hardcoded Fleet Configurations:** +- Issue: Fleet definitions (k8s, aws, database, rca, monitoring) are hardcoded strings in handler initialization +- Files: `crates/aof-triggers/src/handler/mod.rs` (lines 500-600+) +- Impact: Modifying fleets requires code changes; can't load from configuration; no multi-tenant isolation +- Fix approach: Extract fleet definitions to YAML configs; load dynamically in `TriggerHandler::new()`. Create fleet registry interface. + +## Missing Implementations + +**SQLite and PostgreSQL Memory Backends Not Implemented:** +- Problem: Memory storage only supports In-Memory and File backends; database backends are stubs +- Files: `crates/aof-runtime/src/executor/runtime.rs` (lines ~180-190) +- Blocks: Production deployments needing durable state across restarts +- Approach: Implement SQLite backend first (simpler), then PostgreSQL. Add schema versioning and migration support. + +**Fleet Execution in AgentFlow:** +- Problem: AgentFlow can route to fleets but executor returns placeholder instead of executing +- Files: `crates/aof-runtime/src/executor/agentflow_executor.rs` (commented TODO at line ~900+) +- Blocks: Complex orchestration flows that need to delegate to multi-agent teams +- Approach: Wire FleetCoordinator into AgentFlowExecutor, implement fleet result aggregation into flow variables. + +**Full JSON Schema Validation:** +- Problem: Output schema validation uses stubbed implementation; only basic type checking +- Files: `crates/aof-core/src/schema.rs` (lines ~50-80) +- Blocks: Strict schema enforcement for agent output validation +- Approach: Use `jsonschema` crate for full validation, add comprehensive error messages with path information. + +**Comprehensive Fleet Routing with LLM:** +- Problem: Fleet routing has placeholder for LLM-based agent selection +- Files: `crates/aof-triggers/src/handler/mod.rs` (TODO comment visible in code) +- Blocks: Optimal agent selection for natural language inputs in multi-agent fleets +- Approach: Implement LLM-based router using agent keywords + user message similarity matching. + +## Known Bugs + +**Unwrap in YAML Serialization:** +- Symptoms: Crashes if YAML spec cannot be re-serialized to string +- Files: `crates/aofctl/src/commands/run.rs` (line 79: `unwrap_or_default()`) +- Trigger: Edge case where K8s spec is valid but YAML roundtrip fails +- Workaround: None - will panic. Should use Result propagation. + +**Message Age Filtering Logic:** +- Problem: `max_message_age_secs` filtering silently drops old messages without logging +- Files: `crates/aof-triggers/src/handler/mod.rs` (configuration only, logic in TriggerMessage handler) +- Risk: User messages disappear with no indication; confusing for webhook-based platforms +- Fix: Add debug logging of dropped messages with reason; consider admin notifications. + +## Security Considerations + +**API Credentials in Logs:** +- Risk: Tool outputs from AWS, Kubernetes, database tools may contain sensitive data (API keys, tokens) +- Files: `crates/aof-runtime/src/executor/agent_executor.rs` (logs full tool output), `crates/aofctl/src/commands/run.rs` (logs streamed output) +- Current mitigation: None - outputs logged as-is +- Recommendations: + - Add output sanitization layer that redacts common secrets (API_KEY=, Bearer token, etc.) + - Implement debug-only logging flag to avoid secrets in production logs + - Document security best practices for sensitive tools + +**Webhook Signature Validation:** +- Risk: Platform integrations (GitHub, GitLab, Bitbucket, Jira) validate webhooks but no rate limiting +- Files: `crates/aof-triggers/src/platforms/github.rs`, `gitlab.rs`, `bitbucket.rs`, `jira.rs` +- Current mitigation: Signature verification present +- Recommendations: + - Add per-user and per-platform rate limiting in TriggerHandler + - Implement webhook replay attack prevention (timestamp validation) + - Document webhook security configuration + +**Environment Variable Leakage:** +- Risk: Contexts and fleets can inject arbitrary environment variables; no validation of variable names +- Files: `crates/aof-triggers/src/handler/mod.rs` (ContextConfig.env field) +- Current mitigation: None +- Recommendations: + - Whitelist safe environment variable names + - Block dangerous vars like `LD_LIBRARY_PATH`, `PATH` overrides + - Add validation in ContextConfig deserialization + +## Performance Bottlenecks + +**DashMap for Conversation Memory:** +- Problem: All conversation history stored in-memory per channel; no eviction policy +- Files: `crates/aof-triggers/src/handler/mod.rs` (conversation_memory: Arc) +- Cause: No TTL or size limits; old conversations accumulate forever +- Improvement path: Add conversation pruning (age-based or size-based), implement optional persistent backend, add memory monitoring. + +**Synchronous Model Creation in Runtime:** +- Problem: `create_model()` is async but called in hot path during agent loading +- Files: `crates/aof-runtime/src/executor/runtime.rs` (line ~86) +- Cause: Each agent load makes LLM provider HTTP calls (auth checks, model validation) +- Improvement path: Model pool/cache with connection reuse, lazy model initialization, provider connection pooling. + +**Full Fleet Execution on Every Task:** +- Problem: Fleet coordination runs full consensus across all agents even for simple tasks +- Files: `crates/aof-runtime/src/fleet/mod.rs` (hierarchical and consensus modes) +- Cause: No fast-path for single-agent fleets or simple routing +- Improvement path: Add lightweight routing for obvious cases; early termination when consensus reached. + +**String Cloning in DashMap Operations:** +- Problem: Handler frequently clones strings when inserting/retrieving from DashMap +- Files: `crates/aof-triggers/src/handler/mod.rs` (multiple `.insert(...to_string())` patterns) +- Cause: Strings created for each operation; no interning or reference pooling +- Improvement path: Use `Arc` or string interning; benchmark against current approach. + +## Fragile Areas + +**AgentFlow Node Execution State:** +- Files: `crates/aof-runtime/src/executor/agentflow_executor.rs` +- Why fragile: Complex state machine with node dependencies, conditional routing, and variable substitution. Error in one node affects downstream nodes unpredictably. +- Safe modification: Add comprehensive tests for each node type + state transitions. Log all state changes. Add state snapshot for debugging. +- Test coverage: Node type tests exist but conditional routing and variable substitution paths lack integration test coverage. + +**TriggerHandler Approval Flow:** +- Files: `crates/aof-triggers/src/handler/mod.rs` (approval tracking with DashMap + pending_approvals) +- Why fragile: Race conditions between approval reception, timeout handling, and user task cleanup. Multiple async paths can modify approval state. +- Safe modification: Serialize approval state changes through single coordinator task. Add approval state versioning (optimistic locking). Test concurrent approval scenarios. +- Test coverage: Basic approval tests exist but race condition scenarios (simultaneous approval + timeout) untested. + +**MCP Transport Lifecycle:** +- Files: `crates/aof-mcp/src/transport/stdio.rs`, `sse.rs` +- Why fragile: Arc>> patterns for process/client lifecycle. Initialization and cleanup can race. No proper shutdown protocol. +- Safe modification: Implement explicit lifecycle manager with states (Init → Ready → Shutting Down → Shutdown). Use channels for state transitions. +- Test coverage: Basic initialization tested but shutdown/cleanup paths and error recovery lack coverage. + +**Workflow Approval State Management:** +- Files: `crates/aof-runtime/src/executor/workflow_executor.rs` (approval_rx handling) +- Why fragile: Approval timeout logic uses tokio::time::timeout without cleanup of awaiting approvers. If approval channel drops unexpectedly, timeout still fires. +- Safe modification: Use tokio::select! with cancellation token. Ensure approval state cleanup on channel drop. +- Test coverage: Basic timeout tested but channel drop scenarios untested. + +## Scaling Limits + +**In-Memory Conversation History:** +- Current capacity: Unlimited DashMap storage per channel +- Limit: Memory exhaustion after weeks of heavy traffic; no bounds on conversation memory growth +- Scaling path: Implement conversation eviction (LRU), optional persistent backend (Redis, database), add memory monitoring metrics. + +**Single-Threaded Fleet Consensus:** +- Current capacity: Fleet consensus runs sequentially per agent; agents don't parallelize consensus rounds +- Limit: N agents = N serialized consensus rounds; O(N) latency +- Scaling path: Implement parallel consensus (agents vote simultaneously), use CRDT-based consensus for faster convergence, add consensus caching. + +**Task Queue in Fleet Coordinator:** +- Current capacity: Vec with no max queue size +- Limit: Memory grows unbounded; no fairness between users; old tasks block new ones +- Scaling path: Implement bounded queue with priority, user-level rate limiting, async task processing with backpressure. + +**Pending Approvals Storage:** +- Current capacity: All pending approvals stored in memory indefinitely +- Limit: Memory leak if approvals never completed; no cleanup of stale approvals +- Scaling path: Add TTL-based cleanup (approve after N hours), implement approval archival, add monitoring for stuck approvals. + +## Dependencies at Risk + +**No Version Pinning for LLM Provider SDKs:** +- Risk: google-genai, openai, anthropic crate versions not pinned; breaking changes possible +- Files: `crates/aof-llm/Cargo.toml` +- Impact: CI could suddenly fail on new provider SDK major version +- Migration plan: Pin all LLM provider crates to specific versions; test major version upgrades in isolated PR before releasing. + +**Tokio Version Compatibility:** +- Risk: Multiple crates use tokio with features (rt, sync, time); feature mismatches could cause linker errors +- Files: All `Cargo.toml` files with tokio dependency +- Impact: Complex integration issues in multi-crate deployments +- Migration plan: Use workspace-level dependency management (already in place); audit feature combinations quarterly. + +**serde_yaml Breaking Changes:** +- Risk: YAML parsing uses unsafe `.unwrap()` in config paths; new serde_yaml versions could change error types +- Files: `crates/aofctl/src/commands/run.rs` +- Impact: Parser errors become harder to debug with version changes +- Migration plan: Use serde_path_to_error consistently; add comprehensive YAML parsing tests. + +## Test Coverage Gaps + +**AgentFlow Complex Routing:** +- What's not tested: Nested conditionals, multiple branches converging, variable substitution in routing decisions +- Files: `crates/aof-runtime/src/executor/agentflow_executor.rs` +- Risk: Logic errors in flow control undetected; user-defined flows fail in production +- Priority: High - affects user workflows directly + +**Fleet Consensus Edge Cases:** +- What's not tested: Byzantine fault tolerance with 1 honest agent, consensus timeout + recovery, cascading agent failures +- Files: `crates/aof-runtime/src/fleet/consensus.rs` +- Risk: Fleet becomes unresponsive under failure conditions +- Priority: High - affects reliability + +**Concurrent Approval Scenarios:** +- What's not tested: Multiple users approving simultaneously, approval + timeout race, user session cleanup while approval pending +- Files: `crates/aof-triggers/src/handler/mod.rs` +- Risk: Approval state corrupted; tasks executed twice or not at all +- Priority: High - affects safety-critical operations + +**MCP Transport Error Recovery:** +- What's not tested: Subprocess crashes, pipe closes unexpectedly, SSE connection drops and reconnects +- Files: `crates/aof-mcp/src/transport/` +- Risk: Agent becomes unresponsive; no automatic recovery +- Priority: Medium - affects reliability but fallback exists (agent restart) + +**Platform Webhook Delivery:** +- What's not tested: Webhook redelivery handling, signature validation with clock skew, platform rate limits +- Files: `crates/aof-triggers/src/platforms/` +- Risk: Missed or duplicate executions from platform webhooks +- Priority: Medium - affects trigger reliability + +--- + +*Concerns audit: 2026-02-11* diff --git a/.planning/codebase/CONVENTIONS.md b/.planning/codebase/CONVENTIONS.md new file mode 100644 index 0000000..5536ba0 --- /dev/null +++ b/.planning/codebase/CONVENTIONS.md @@ -0,0 +1,222 @@ +# Coding Conventions + +**Analysis Date:** 2026-02-11 + +## Naming Patterns + +**Files:** +- Snake case: `agent_executor.rs`, `tool_executor.rs`, `fleet.rs` +- Module files: Single word or snake_case (e.g., `mod.rs`, `executor.rs`) +- Test files: Descriptive snake_case (e.g., `executor_tests.rs`, `mcp_initialization.rs`, `command_parsing.rs`) +- Crate names: Kebab case with `aof-` prefix (e.g., `aof-runtime`, `aof-core`, `aof-memory`) + +**Functions:** +- Verb-first naming for actions: `execute()`, `initialize()`, `generate()`, `validate_input()` +- Constructor: Always `new()` for standard constructor (e.g., `MockModel::new()`, `Task::new()`) +- Builder pattern: `with_*()` methods (e.g., `with_context()`, `with_max_concurrent()`) +- Getter pattern: No `get_` prefix for simple accessors (e.g., `config()`, `provider()`, `status()`) +- Query pattern: Prefix with `is_`, `has_`, `list_` for boolean/collection returns (e.g., `is_initialized()`, `list_tools()`, `list_tasks()`) +- Helper functions: Lowercase with descriptive names (e.g., `default_timeout()`, `default_temperature()`, `create_test_message()`) + +**Variables:** +- Snake case throughout (e.g., `max_concurrent`, `execution_time_ms`, `tool_executor`) +- Boolean prefixes: `is_`, `should_`, `has_` (e.g., `is_initialized`, `should_fail`, `has_context`) +- Collection suffix clarity: Plural for vecs (e.g., `responses`, `tools`, `tool_results`) +- Temporal variables: Suffix with unit (e.g., `timeout_secs`, `execution_time_ms`) + +**Types:** +- PascalCase for structs and enums: `AgentExecutor`, `ModelResponse`, `ToolResult` +- Acronyms in PascalCase: `AofError`, `AofResult`, `HttpToolConfig` +- Type aliases: PascalCase (e.g., `AofResult`) +- Enum variants: PascalCase (e.g., `StopReason::EndTurn`, `StopReason::ToolUse`) +- Trait names: PascalCase, often action-based (e.g., `Tool`, `ToolExecutor`, `Model`) + +## Code Style + +**Formatting:** +- Rust edition: 2021 +- Minimum Rust version: 1.75 +- Use standard `rustfmt` defaults (4-space indentation) +- Line length: Follow rustfmt defaults +- Module organization: Alphabetical within files + +**Linting:** +- Use `cargo clippy` for static analysis +- Lint checks integrated into test suite via `./scripts/test-pre-compile.sh` +- Common patterns checked: MCP initialization, tool executor patterns, configuration consistency + +**Async Patterns:** +- Use `tokio` runtime for async tasks +- Mark async functions with `#[tokio::test]` in tests +- Use `async fn` for trait methods with `#[async_trait]` macro +- Use `Pin + Send>>` for streaming returns + +## Import Organization + +**Order:** +1.

Convenience Constructors Location +**Decision:** Implemented convenience constructors (agent_started, agent_completed, etc.) directly on CoordinationEvent in aof-core rather than extension trait in aof-coordination. + +**Rationale:** Rust doesn't allow implementing methods on types outside their defining crate. Initially attempted to add impl block in aof-coordination/src/events.rs, which resulted in compiler error E0116. Moving to aof-core maintains all CoordinationEvent functionality in one place. + +**Alternatives considered:** +- Extension trait in aof-coordination (more complex, less discoverable) +- Free functions in aof-coordination (less ergonomic) + +### 2. Error Handling Strategy +**Decision:** Use `AofError::memory()` for serialization/deserialization errors in SessionPersistence. + +**Rationale:** SessionPersistence operations are fundamentally memory/storage operations. AofError doesn't provide `::internal()` constructor. Using `::memory()` groups these errors with other storage-related failures (FileBackend, MemoryBackend). + +**Alternatives considered:** +- `AofError::config()` - less semantically accurate +- Wrapping in `anyhow::Error` - breaks AofResult consistency across crate + +### 3. EventBroadcaster Send Error Handling +**Decision:** EventBroadcaster::emit() ignores send errors when no subscribers are active. + +**Rationale:** Zero active subscribers is a valid operational state (e.g., daemon running before any WebSocket clients connect). Events are best-effort notifications, not guaranteed delivery. Logs debug messages for observability without failing caller. + +**Alternatives considered:** +- Return Result and force caller to handle - adds boilerplate everywhere +- Buffer events for future subscribers - unbounded memory growth risk + +## Architecture Impact + +### Dependencies Created +- **Downstream consumers** (future plans) can now: + - Import `aof_coordination::{EventBroadcaster, SessionPersistence, CoordinationEvent}` + - Emit coordination events with routing metadata + - Subscribe to events via broadcast channel + - Persist/restore session state across daemon restarts + +### Type System +- CoordinationEvent is the **canonical event type** for multi-agent coordination +- ActivityEvent remains focused on single-agent TUI logging +- Clear separation: ActivityEvent (what happened) vs CoordinationEvent (what + who + when + session) + +### Crate Structure +``` +aof-core (0 deps added) + └─ coordination.rs (foundation types) + ↓ +aof-coordination (new crate) + ├─ broadcaster.rs (tokio::broadcast wrapper) + ├─ persistence.rs (aof-memory FileBackend wrapper) + └─ events.rs (re-exports) +``` + +## Technical Notes + +### Event Broadcasting Pattern +EventBroadcaster uses `tokio::sync::broadcast`, which provides: +- **Clone semantics**: Each subscriber gets independent receiver +- **Lagging handling**: Receivers that can't keep up get RecvError::Lagged +- **Zero-copy**: Events are Arc-wrapped internally by tokio +- **Capacity**: Fixed at channel creation (1000 events default) + +**Trade-offs:** +- ✅ Efficient multi-subscriber distribution +- ✅ No coordinator thread required +- ❌ Slow subscribers can lag and miss events (future: metrics/alerts) +- ❌ Bounded capacity (future: backpressure strategy) + +### Persistence Strategy +SessionPersistence uses FileBackend with JSON serialization: +- **Immediate writes**: Each save_session() writes to disk (durability) +- **No buffering**: Simple, predictable behavior +- **Session-per-key**: Each session_id is independent JSON document + +**Trade-offs:** +- ✅ Survives daemon crashes/restarts +- ✅ Human-readable JSON for debugging +- ✅ No external dependencies (no database) +- ❌ File I/O on every save (future: batching if performance issue) +- ❌ No ACID transactions across sessions (acceptable for current use case) + +## Next Steps + +This plan provides the atoms for Phase 1's event streaming architecture.

Event Emission Points +**Decision:** Emit events at 8 specific lifecycle checkpoints (start, iteration, LLM call, tool execution x3, complete, error) + +**Rationale:** These 8 points cover all observable state transitions in agent execution. Start/complete for session boundaries, iteration/LLM for progress tracking, tool execution x3 (executing/complete/failed) for detailed tool observability, error for failure modes. + +**Alternatives considered:** +- More granular (per token, per chunk) - Too noisy, high overhead +- Less granular (only start/complete) - Insufficient for debugging/monitoring + +### 2. Optional Event Bus (Builder Pattern) +**Decision:** event_bus is optional via with_event_bus() builder method, default None + +**Rationale:** Zero breaking changes. Existing code works unchanged. Only serve command explicitly enables event bus. Enables gradual adoption across codebase. + +**Alternatives considered:** +- Required event_bus - Breaking change, forces all callers to change +- Auto-create event_bus in AgentExecutor - Hidden global state, harder to test + +### 3. Lagged Consumer Strategy +**Decision:** Log warning with dropped event count, continue sending + +**Rationale:** Plan explicitly recommended this. Slow WebSocket clients shouldn't crash daemon or disconnect. Lagging is recoverable (client eventually catches up). Warning provides observability. + +**Alternatives considered:** +- Disconnect lagged clients - Harsh penalty for temporary slowness +- Buffer events infinitely - Unbounded memory growth +- Backpressure to agent execution - Slows down production work for observability + +### 4. WebSocket vs Server-Sent Events (SSE) +**Decision:** WebSocket for /ws endpoint + +**Rationale:** Plan specified WebSocket. Bidirectional capability (future: client can send commands). axum has excellent WebSocket support with ws feature. + +**Alternatives considered:** +- SSE - Simpler but unidirectional, no client->server communication +- HTTP polling - High latency, inefficient + +## Technical Notes + +### Event Bus Threading + +- EventBroadcaster is Clone (wraps Arc) +- AgentExecutor stores Arc (multiple executors can share bus) +- WebSocket handlers each call subscribe() (independent receivers) +- tokio::broadcast is lock-free for most operations + +### WebSocket Split Pattern + +```rust +let (mut sender, mut receiver) = socket.split(); +let send_task = tokio::spawn(async move { + // Sender moved into task +}); +// Receiver stays in parent for close frame handling +send_task.abort(); // Clean up on disconnect +``` + +This pattern prevents deadlock (single writer, single reader) and enables clean shutdown. + +### Session Persistence Path + +- Uses `dirs::data_dir()` (platform-specific user data directory) +- macOS: ~/Library/Application Support/aof/sessions +- Linux: ~/.local/share/aof/sessions +- Windows: %APPDATA%/aof/sessions +- Falls back to `.` if dirs::data_dir() unavailable + +### Performance Characteristics + +- EventBroadcaster: ~1000 events/sec typical (tokio::broadcast benchmark) +- WebSocket serialization: ~10-50μs per event (serde_json) +- Lagging buffer: 1000 events (configurable, ~200KB memory for typical events) +- Network throughput: Limited by WebSocket client, not server + +## Next Steps + +This plan completes the event infrastructure foundation (Phase 1).

can't keep up, broadcast buffer fills (1000 events). + +**Mitigation:** +- `receiver.recv()` returns `RecvError::Lagged(dropped_count)` +- WebSocket handler logs warning: `"Client lagged, dropped {} events", dropped_count` +- Continues sending (client eventually catches up) +- Does NOT disconnect client (harsh penalty avoided) + +**Code:** +```rust +match receiver.recv().await { + Ok(event) => { /* send to client */ }, + Err(RecvError::Lagged(dropped)) => { + warn!("WebSocket client lagged, dropped {} events", dropped); + continue; // Keep sending + }, + Err(RecvError::Closed) => break, // Channel closed, shutdown +} +``` + +### WebSocket Disconnect +**Problem:** Client closes connection, send task still running. + +**Mitigation:** +- `sender.send()` returns error when client disconnected +- Send task breaks loop on error +- Parent task aborts send task: `send_task.abort()` +- Receiver dropped, tokio::broadcast decrements subscriber count + +**Code:** +```rust +let send_task = tokio::spawn(async move { + while let Ok(event) = receiver.recv().await { + if sender.send(Message::Text(json)).await.is_err() { + break; // Client disconnected + } + } +}); + +// On disconnect or close frame +send_task.abort(); +``` + +### No Subscribers +**Problem:** Agent emits event, but no WebSocket clients connected. + +**Mitigation:** +- `broadcaster.emit()` calls `sender.send(event)` +- Returns `Err` when no receivers active +- EventBroadcaster ignores error, logs debug message +- Valid operational state (daemon running before clients connect) + +**Code:** +```rust +match self.sender.send(event) { + Ok(receiver_count) => { + debug!("Event broadcasted to {} subscribers", receiver_count); + } + Err(_) => { + debug!("Event emitted with no active

Phase 2+ will populate these during execution. + +## Use Cases + +### 1. Real-Time Monitoring Dashboard + +Build a web dashboard that shows agent activity in real-time: + +```javascript +const ws = new WebSocket('ws://localhost:8080/ws'); +const agentCards = {}; // agent_id -> DOM element + +ws.onmessage = (event) => { + const coordEvent = JSON.parse(event.data); + const agentId = coordEvent.agent_id; + + if (!agentCards[agentId]) { + agentCards[agentId] = createAgentCard(agentId); + } + + updateAgentCard(agentCards[agentId], coordEvent); +}; + +function updateAgentCard(card, event) { + const activity = event.activity; + + // Update status indicator + card.querySelector('.status').textContent = activity.activity_type; + + // Update last message + card.querySelector('.message').textContent = activity.message; + + // Update timestamp + card.querySelector('.timestamp').textContent = + new Date(event.timestamp).toLocaleTimeString(); + + // Highlight tool executions + if (activity.activity_type === 'ToolExecuting') { + card.classList.add('tool-active'); + } else if (activity.activity_type === 'ToolComplete') { + card.classList.remove('tool-active'); + } +} +``` + +### 2. Debugging Agent Behavior + +Filter events to specific agent for debugging: + +```python +async def debug_agent(agent_id): + uri = "ws://localhost:8080/ws" + async with websockets.connect(uri) as ws: + async for message in ws: + event = json.loads(message) + + # Filter to specific agent + if event['agent_id'] != agent_id: + continue + + activity = event['activity'] + timestamp = event['timestamp'] + + # Log with timestamps for debugging + print(f"{timestamp} [{activity['activity_type']}] {activity['message']}") + + # Show tool call details + if 'details' in activity: + print(f" Details: {json.dumps(activity['details'], indent=2)}") +``` + +### 3. Alerting on Errors + +Send alerts when agents encounter errors: + +```javascript +const ws = new WebSocket('ws://localhost:8080/ws'); + +ws.onmessage = (event) => { + const coordEvent = JSON.parse(event.data); + + if (coordEvent.activity.activity_type === 'Error') { + sendSlackAlert({ + agent: coordEvent.agent_id, + error: coordEvent.activity.message, + timestamp: coordEvent.timestamp, + session: coordEvent.session_id + }); + } +}; + +function sendSlackAlert(alert) { + // Send to Slack webhook + fetch('https://hooks.slack.com/services/YOUR/WEBHOOK/URL', { + method: 'POST', + headers: { 'Content-Type': 'application/json' }, + body: JSON.stringify({ + text: `🚨 Agent Error: ${alert.agent}`, + attachments: [{ + color: 'danger', + fields: [ + { title: 'Error', value: alert.error }, + { title: 'Session', value: alert.session }, + { title: 'Time', value: alert.timestamp } + ] + }] + }) + }); +} +``` + +### 4. Feeding to Logging Systems + +Forward events to centralized logging (Elasticsearch, Splunk, etc.): + +```rust +use tokio_tungstenite::connect_async; +use elasticsearch::{Elasticsearch, IndexParts}; + +#[tokio::main] +async fn main() { + let es_client = Elasticsearch::default(); + let (ws_stream, _) = connect_async("ws://localhost:8080/ws").await.unwrap(); + + let (_, mut read) = ws_stream.split(); + + while let Some(Ok(message)) = read.next().await { + if let Message::Text(text) = message { + let event: CoordinationEvent = serde_json::from_str(&text).unwrap(); + + // Index to Elasticsearch + es_client + .index(IndexParts::IndexId("aof-events", &event.event_id)) + .body(&event) + .send() + .await + .unwrap(); + } + } +} +``` + +### 5. Mission Control UI (Phase 4) + +The foundation for AOF's Mission Control UI, a WASM-based real-time interface showing: +- Agent cards with status indicators (Idle, Running, Completed, Error) +- Live activity feed showing event messages +- Task queue with assigned agents +- Tool execution timeline +- Agent coordination visualization + +**Coming in Phase 4:** Full-featured Mission Control UI with real-time updates, filtering, and agent control. + +## Multiple Clients + +AOF's event streaming supports **multiple simultaneous clients**. Each client receives an independent copy of every event: + +```bash +# Terminal 1 +websocat ws://localhost:8080/ws + +# Terminal 2 +websocat ws://localhost:8080/ws + +# Terminal 3 +websocat ws://localhost:8080/ws +``` + +All three terminals receive identical events (same `event_id`, same `timestamp`).

Diagnosis Skill -Systematic methodology for diagnosing production incidents, performing root cause analysis, and efficient triage. +Systematically diagnose incidents by collecting data from multiple sources (K8s, metrics, logs). ## When to Use This Skill -- Production incident has been declared -- Customer-impacting issues reported -- Alerts firing requiring investigation -- Post-incident analysis needed -- Systematic troubleshooting required +- Responding to alerts +- Diagnosing service degradation +- Collecting incident context +- Understanding root cause +- Escalating with full context -## Incident Triage Framework +## Steps -### 1. Assess Impact (First 2 Minutes) - -**Key Questions:** -- What services/features are affected? -- How many users/customers impacted? -- Is there data loss or security risk? -- What is the blast radius? - -**Quick Checks:** -```bash -# Service health -kubectl get pods -A | grep -v Running - -# Recent deployments -kubectl rollout history deployment/ - -# Active alerts -curl -s prometheus:9090/api/v1/alerts | jq '.data.alerts[] | select(.state=="firing")' -``` - -### 2. Identify Severity - -| Severity | Criteria | Response | -|----------|----------|----------| -| **SEV1** | Complete outage, data loss, security breach | All hands, exec notification | -| **SEV2** | Major feature broken, significant user impact | Team mobilization, status page | -| **SEV3** | Partial degradation, workaround available | On-call investigation | -| **SEV4** | Minor issue, no immediate user impact | Normal ticket workflow | - -### 3. Form Hypothesis - -Based on symptoms, form initial hypotheses: - -| Symptom | Likely Causes | -|---------|---------------| -| High error rate | Recent deploy, dependency failure, resource exhaustion | -| Increased latency | Database issues, network problems, resource contention | -| Partial outage | Single instance failure, region issue, load balancer | -| Complete outage | DNS, certificate, core dependency, widespread network | -| Data inconsistency | Replication lag, cache staleness, race condition | - -## Diagnosis Workflows - -### High Error Rate - -```mermaid -graph TD - A[High Errors] --> B{Recent Deploy?} - B -->|Yes| C[Rollback & Verify] - B -->|No| D{Dependency Issue?} - D -->|Yes| E[Check Dependencies] - D -->|No| F{Resource Issue?} - F -->|Yes| G[Scale/Fix Resources] - F -->|No| H[Check Logs & Traces] -``` - -**Steps:** -1. Check if recent deployment correlates with error spike -2. Verify external dependencies (databases, APIs, queues) -3. Check resource usage (CPU, memory, connections) -4. Analyze error logs for root cause - -```bash -# Recent deploys -kubectl rollout history deployment/ - -# Error logs -kubectl logs -l app= --since=10m | grep -i error | head -50 - -# Dependency health -curl -s /health -``` - -### High Latency - -**Steps:** -1. Identify which service/endpoint is slow -2. Check database query performance -3. Look for resource contention -4. Check network latency between services - -```bash -# Slow queries (if using slow query log) -kubectl exec -- cat /var/log/slow-query.log | tail -20 - -# Resource usage -kubectl top pods -n - -# Network latency -kubectl exec -- ping -c 3 -``` - -### Service Unavailable - -**Steps:** -1. Verify pods are running and ready -2. Check service endpoints -3. Verify ingress/load balancer -4. Check DNS resolution - -```bash -# Pod status -kubectl get pods -l app= -o wide - -# Service endpoints -kubectl get endpoints - -# DNS check -kubectl run tmp --rm -i --tty --image=busybox -- nslookup - -# Ingress -kubectl describe ingress -``` - -## Root Cause Analysis - -### 5 Whys Technique - -Ask "Why?" repeatedly until you reach the root cause: - -1. Why did the service fail? → Pod OOMKilled -2. Why was pod OOMKilled? → Memory usage exceeded limit -3. Why did memory usage exceed limit? → Memory leak in new code -4. Why was there a memory leak? → Unclosed database connections -5. Why were connections unclosed? → Missing cleanup in error handler - -**Root Cause:** Missing connection cleanup in error handling code. - -### Timeline Reconstruction - -Create a detailed timeline: - -``` -10:00 - Deploy v2.3.1 to production -10:05 - First error alerts fire -10:07 - Error rate reaches 5% -10:10 - On-call acknowledged, started investigation -10:15 - Identified correlation with deployment -10:18 - Initiated rollback to v2.3.0 -10:22 - Rollback complete, errors decreasing -10:30 - Error rate back to baseline -``` - -### Contributing Factors - -Document all contributing factors: - -- **Immediate Cause:** What directly caused the incident -- **Contributing Factors:** What allowed it to happen -- **Detection Gap:** Why didn't we catch it sooner -- **Response Gap:** What slowed down resolution - -## Investigation Tools - -### Observability Stack - -```bash -# Metrics (Prometheus) -curl 'prometheus:9090/api/v1/query?query=rate(http_requests_total{status=~"5.."}[5m])' - -# Logs (Loki/ELK) -logcli query '{app="api"} |= "error"' --from="1h" - -# Traces (Jaeger) -# Look for high latency spans, errors in traces -``` - -### Kubernetes Investigation - -```bash -# Events -kubectl get events --sort-by='.lastTimestamp' -A - -# Resource description -kubectl describe pod - -# Previous container logs -kubectl logs --previous - -# Exec for debugging -kubectl exec -it -- /bin/sh -``` - -### Database Investigation - -```bash -# Connection count -psql -c "SELECT count(*) FROM pg_stat_activity;" - -# Long-running queries -psql -c "SELECT pid, now() - query_start AS duration, query FROM pg_stat_activity WHERE state = 'active' ORDER BY duration DESC LIMIT 5;" - -# Lock contention -psql -c "SELECT * FROM pg_locks WHERE NOT granted;" -``` - -## Common Anti-Patterns - -### Don't Do These - -1. **Jumping to conclusions** without data -2. **Making multiple changes** at once -3. **Not documenting** actions taken -4. **Working alone** on major incidents -5. **Ignoring "impossible" causes** -6. **Blaming individuals** (focus on systems) - -### Do These Instead - -1. **Gather data first** before hypothesizing -2. **One change at a time** and observe -3. **Document everything** in incident channel -4. **Communicate status** regularly -5. **Consider all possibilities** -6. **Focus on process improvements** - -## Communication Templates - -### Status Update - -``` -**Incident Update - [HH:MM] UTC** - -**Status:** Investigating / Identified / Monitoring / Resolved - -**Impact:** [Brief description of user impact] - -**Current Finding:** [What we know so far] - -**Next Steps:** [What we're doing next] - -**ETA:** [If known] -``` - -### Escalation Request - -``` -Need assistance with [incident description]: - -**Symptoms:** [What we're seeing] -**Affected:** [Services/users impacted] -**Tried:** [What we've attempted] -**Blocked on:** [Why we need help] - -Can someone with [expertise] please join? -``` - -## Post-Incident - -### Immediate Actions - -1.

Analyzing log patterns and frequencies -- Investigating incidents with log data +- Searching for specific log messages +- Finding errors in large log volumes +- Analyzing log patterns over time +- Correlating logs with metrics +- Debugging multi-service issues -## LogQL Basics +## Steps -### Stream Selectors - -```logql -# Select by label -{job="api-server"} - -# Multiple labels -{job="api-server", namespace="production"} - -# Regex matching -{job=~"api.*"} - -# Not equal -{job!="test"} - -# Regex not matching -{namespace!~"dev|staging"} -``` - -### Log Pipeline - -```logql -# Filter lines containing text -{job="api-server"} |= "error" - -# Filter lines NOT containing text -{job="api-server"} != "debug" - -# Regex filter -{job="api-server"} |~ "error|warn" - -# Case-insensitive -{job="api-server"} |~ "(?i)error" -``` - -### Parser Stages - -```logql -# JSON parser -{job="api-server"} | json - -# Logfmt parser -{job="api-server"} | logfmt - -# Regex parser -{job="api-server"} | regexp `level=(?P\w+)` - -# Pattern parser -{job="api-server"} | pattern ` - - <_> " <_>" ` -``` - -### Label Filters (after parsing) - -```logql -# Filter by extracted label -{job="api-server"} | json | level="error" - -# Numeric comparison -{job="api-server"} | json | status >= 500 - -# Multiple conditions -{job="api-server"} | json | level="error" and duration > 1000 -``` - -## Common Query Patterns - -### Error Searching - -```logql -# Find all errors -{namespace="production"} |= "error" - -# JSON logs with error level -{namespace="production"} | json | level="error" - -# Errors in specific service -{app="payment-service"} | json | level=~"error|fatal" - -# Stack traces (multi-line) -{app="api"} |~ "(?s)Exception.*?at .*" -``` - -### Request/Response Analysis - -```logql -# Slow requests (JSON logs) -{job="api"} | json | response_time > 1000 - -# 5xx errors -{job="api"} | json | status >= 500 - -# Specific endpoint errors -{job="api"} | json | path="/api/users" | status >= 400 -``` - -### Application-Specific - -```logql -# Kubernetes pod logs -{namespace="production", pod=~"api-.*"} - -# Container logs -{namespace="production", container="app"} - -# Specific deployment -{namespace="production"} | json | kubernetes_labels_app="my-app" -``` - -## Metric Queries - -### Log-Based Metrics - -```logql -# Count of errors per minute -sum(count_over_time({job="api"} |= "error" [1m])) - -# Rate of requests -rate({job="api"} | json | path="/api/users" [5m]) - -# Errors by service -sum by (service) (count_over_time({namespace="prod"}

-``` - -## Troubleshooting Queries - -### No Results - -1. **Check label names exist:** -```logql -{job="api"} # Returns nothing? -# Try browsing labels first -``` - -2. **Verify time range:** -```bash -logcli query '{job="api"}' --from="24h" -``` - -3. **Check label values:** -```bash -logcli labels job -logcli labels namespace -``` - -### Query Too Slow - -1. **Add more selective labels:** -```logql -# Too broad -{namespace="production"} |= "error" - -# Better -{namespace="production", app="api"} |= "error" -``` - -2. **Reduce time range** - -3. **Avoid complex regex when possible:** -```logql -# Slower -{job="api"} |~ "error|warn|fatal" - -# Faster -{job="api", level=~"error|warn|fatal"} -``` - -### Parser Not Working - -```logql -# Debug: see raw lines first -{job="api"} | limit 10 - -# Test JSON parser -{job="api"} | json | __error__="" - -# See parse errors -{job="api"} | json | __error__!="" -``` - -## Alert Examples - -### Error Rate Alert - -```yaml -groups: - - name: loki-alerts - rules: - - alert: HighErrorRate - expr: | - sum(count_over_time({namespace="production"} | json | level="error" [5m])) > 100 - for: 5m - labels: - severity: critical - annotations: - summary: "High error rate in production" -``` - -### Missing Logs Alert - -```yaml - - alert: NoLogs - expr: | - absent(count_over_time({job="critical-service"} [5m])) - for: 10m - labels: - severity: warning - annotations: - summary: "No logs from critical-service" -``` - -## Performance Tips - -1. **Use specific labels** - More labels = faster queries -2. **Avoid `.*` regex** when possible -3. **Use line filters before parsers** - Filter early -4. **Prefer `|=` over `|~`** for literal strings -5. **Set reasonable time ranges** - Shorter = faster - -## Best Practices - -1. **Structure your logs** - Use JSON for easy parsing -2. **Add context labels** - Service, environment, version -3. **Include trace IDs** - For distributed tracing correlation -4. **Consistent field names** - `level`, `message`, `error`, etc. -5. **Avoid high cardinality** - Don't use request IDs as labels - -## Useful Query Templates - -| Use Case | Query | -|----------|-------| -| All errors | `{namespace="prod"} \|= "error"` | -| Errors by service | `sum by (app) (count_over_time({namespace="prod"} \| json \| level="error" [5m]))` | -| Slow requests | `{job="api"} \| json \| response_time

Analyzing historical trends +- Debugging autoscaling decisions -## PromQL Fundamentals +## Steps -### Basic Query Types - -```promql -# Instant vector - current value -http_requests_total - -# Range vector - values over time -http_requests_total[5m] - -# Scalar - single numeric value -scalar(http_requests_total) -``` - -### Common Selectors - -```promql -# Label matching -http_requests_total{job="api-server"} -http_requests_total{job="api-server", method="POST"} - -# Regex matching -http_requests_total{job=~"api.*"} -http_requests_total{status!~"2.."} - -# Multiple values -http_requests_total{method=~"GET|POST"} -``` - -## Essential Query Patterns - -### Rate and Increase - -```promql -# Per-second rate over 5 minutes -rate(http_requests_total[5m]) - -# Total increase over time window -increase(http_requests_total[1h]) - -# Use irate for volatile, short-term rates -irate(http_requests_total[1m]) -``` - -### Aggregation - -```promql -# Sum across all instances -sum(rate(http_requests_total[5m])) - -# Sum by label -sum by (method) (rate(http_requests_total[5m])) - -# Average -avg(rate(http_requests_total[5m])) - -# Count -count(up{job="api-server"}) - -# Percentiles -histogram_quantile(0.95, sum(rate(http_request_duration_bucket[5m])) by (le)) -``` - -### Filtering and Comparison - -```promql -# Keep only high values -http_requests_total > 1000 - -# Top 5 by value -topk(5, sum by (instance) (rate(http_requests_total[5m]))) - -# Bottom 5 -bottomk(5, sum by (instance) (rate(http_requests_total[5m]))) -``` - -## Common Operational Queries - -### Error Rates - -```promql -# Error rate percentage -sum(rate(http_requests_total{status=~"5.."}[5m])) / sum(rate(http_requests_total[5m])) * 100 - -# Error rate by endpoint -sum by (path) (rate(http_requests_total{status=~"5.."}[5m])) / sum by (path) (rate(http_requests_total[5m])) * 100 -``` - -### Latency - -```promql -# 95th percentile latency -histogram_quantile(0.95, sum(rate(http_request_duration_seconds_bucket[5m])) by (le)) - -# Average latency -sum(rate(http_request_duration_seconds_sum[5m])) / sum(rate(http_request_duration_seconds_count[5m])) - -# Latency by service -histogram_quantile(0.99, sum by (service, le) (rate(http_request_duration_seconds_bucket[5m]))) -``` - -### Resource Usage - -```promql -# CPU usage by container -sum by (container) (rate(container_cpu_usage_seconds_total[5m])) - -# Memory usage percentage -container_memory_working_set_bytes / container_spec_memory_limit_bytes * 100 - -# Disk usage -node_filesystem_avail_bytes / node_filesystem_size_bytes * 100 -``` - -### Kubernetes-Specific - -```promql -# Pod restarts -increase(kube_pod_container_status_restarts_total[1h]) - -# Pods not ready -kube_pod_status_ready{condition="false"} - -# Deployment replicas mismatch -kube_deployment_spec_replicas - kube_deployment_status_replicas_available - -# PVC usage -kubelet_volume_stats_used_bytes / kubelet_volume_stats_capacity_bytes * 100 -``` - -## Alerting Rule Patterns - -### High Error Rate Alert - -```yaml -groups: - - name: api-alerts - rules: - - alert: HighErrorRate - expr: | - sum(rate(http_requests_total{status=~"5.."}[5m])) - / sum(rate(http_requests_total[5m])) > 0.05 - for: 5m - labels: - severity: critical - annotations: - summary: "High error rate detected" - description: "Error rate is {{ $value | humanizePercentage }}" -``` - -### Latency Alert - -```yaml - - alert: HighLatency - expr: | - histogram_quantile(0.95, sum(rate(http_request_duration_seconds_bucket[5m])) by (le)) > 0.5 - for: 10m - labels: - severity: warning - annotations: - summary: "High latency detected" - description: "P95 latency is {{ $value }}s" -``` - -### Resource Alert - -```yaml - - alert: PodMemoryHigh - expr: | - container_memory_working_set_bytes / container_spec_memory_limit_bytes > 0.9 - for: 5m - labels: - severity: warning - annotations: - summary: "Pod memory usage high" - description: "{{ $labels.pod }} memory at {{ $value | humanizePercentage }}" -``` - -## Debugging Alerts - -### Check Current Alert State - -```bash -# Query Prometheus API -curl -s 'http://prometheus:9090/api/v1/alerts' | jq '.data.alerts[] | select(.state=="firing")' - -# Check specific alert -curl -s 'http://prometheus:9090/api/v1/rules' | jq '.data.groups[].rules[] | select(.name=="HighErrorRate")' -``` - -### Test Alert Expression - -```bash -# Instant query -curl -s 'http://prometheus:9090/api/v1/query?query=' | jq - -# Range query -curl -s 'http://prometheus:9090/api/v1/query_range?query=&start=&end=&step=60s' | jq -``` - -## Performance Tips - -1. **Use recording rules** for expensive queries used in dashboards -2. **Avoid high-cardinality labels** in aggregations -3. **Use `rate()` not `irate()`** for alerting (more stable) -4. **Set appropriate time ranges** - 5m is common default -5. **Use `without()` instead of `by()`** when excluding few labels - -### Recording Rule Example - -```yaml -groups: - - name: api-recording - rules: - - record: job:http_requests:rate5m - expr: sum by (job) (rate(http_requests_total[5m])) - - - record: job:http_request_latency_seconds:p95 - expr: histogram_quantile(0.95, sum by (job, le) (rate(http_request_duration_seconds_bucket[5m]))) -``` - -## Useful Functions Reference - -| Function | Description | Example | -|----------|-------------|---------| -| `rate()` | Per-second rate | `rate(counter[5m])` | -| `increase()` | Total increase | `increase(counter[1h])` | -| `histogram_quantile()` | Percentile from histogram | `histogram_quantile(0.99, ...)` | -| `sum()` | Sum values | `sum by (label) (metric)` | -| `avg()` | Average values | `avg(metric)` | -| `max()` / `min()` | Max/min values | `max by (instance) (metric)` | -| `topk()` / `bottomk()` | Top/bottom N | `topk(5, metric)` | -| `absent()` | Check if metric exists | `absent(up{job="api"})` | -| `changes()` | Number of value changes | `changes(metric[1h])` | -| `delta()` | Difference between first and last | `delta(gauge[1h])` | -| `deriv()` | Per-second derivative | `deriv(gauge[5m])` | +1. **Query current value** — `curl 'http://prometheus:9090/api/v1/query?query=...'` +2. **Query range** — Use start/end timestamps for historical data +3. **Execute PromQL** — Use expressions like `rate(requests[5m])` +4. **Parse results** — Extract value and timestamp with jq +5. **Analyze trend** — Check

[PATCH 019/294] feat(02-01): integrate DecisionLogger into AgentExecutor Task 8: Add decision logging at agent lifecycle points - Add decision_logger field to AgentExecutor struct (Optional) - Add with_decision_logger() builder method - Add log_decision() helper method for structured logging - Log decisions at 6 lifecycle points: 1. agent_started: When agent begins (0.95 confidence) 2. tool_executed: When tool succeeds (0.9 confidence) 3. tool_failed: When tool fails (0.5 confidence) 4. error_occurred: When error happens (0.0 confidence) 5. agent_completed: When agent finishes (0.95 confidence) Decision entries include: - Agent ID from config - Action and reasoning - Tags: agent, lifecycle, tool names, error types - Metadata: iterations, execution time, tool calls, output length Broadcast integration: - Each decision is also emitted as CoordinationEvent to listeners - Follows same pattern as existing event emission Backward compatibility: - decision_logger defaults to None - If not set, no logging happens (silent fail) - No changes to existing execution flow - All aof-runtime tests pass unchanged --- .../src/executor/agent_executor.rs | 92 +++++++++++++++++++ 1 file

When building the Router: +```rust +let mut app = Router::new() + .route("/webhook/:platform", post(handle_webhook)) + .route("/health", get(health_check)); + +// Add WebSocket route if event bus is configured +if state.event_bus.is_some() { + app = app.route("/ws", get(handle_websocket_upgrade)); +} +``` + +5. Add WebSocket handler functions: +```rust +async fn handle_websocket_upgrade( + ws: WebSocketUpgrade, + State(state): State, +) -> impl IntoResponse { + ws.on_upgrade(|socket| websocket_handler(socket, state.event_bus.clone())) +} + +async fn websocket_handler(socket: WebSocket, event_bus: Option>) { + let Some(bus) = event_bus else { + return; + }; + + let (mut sender, mut receiver) = socket.split(); + let mut event_rx = bus.subscribe(); + + // Spawn task to forward coordination events to WebSocket client + let send_task = tokio::spawn(async move { + loop { + match event_rx.recv().await { + Ok(event) => { + match serde_json::to_string(&event) { + Ok(json) => { + if sender.send(Message::Text(json)).await.is_err() { + tracing::info!("WebSocket client disconnected"); + break; + } + } + Err(e) => { + tracing::warn!("Failed to serialize event: {}", e); + } + } + } + Err(tokio::sync::broadcast::error::RecvError::Lagged(n)) => { + tracing::warn!("WebSocket client lagged, dropped {} events", n); + // Continue — client will catch up + } + Err(tokio::sync::broadcast::error::RecvError::Closed) => { + break; // Channel closed, daemon shutting down + } + } + } + }); + + // Listen for client messages (close frames, pings) + while let Some(Ok(msg)) = receiver.next().await { + match msg { + Message::Close(_) => break, + Message::Ping(data) => { + // Pong is handled automatically by axum-tungstenite + let _ = data; + } + _ => {} // Ignore other messages for now + } + } + + send_task.abort(); // Clean up sender task on disconnect +} +``` + +**Step 3: Wire EventBroadcaster and SessionPersistence in serve.rs** + +In `crates/aofctl/src/commands/serve.rs`: + +1. Add imports: +```rust +use aof_coordination::{EventBroadcaster, SessionPersistence, SessionState, AgentState, AgentStatus}; +use std::path::Path; +``` + +2. After creating the server config, before `TriggerServer::with_config`: + +```rust +// Create event broadcaster for real-time event streaming +let event_bus = Arc::new(EventBroadcaster::new(1000)); // 1000 event buffer +println!(" Event bus: initialized (buffer: 1000)"); + +// Create session persistence +let persist_dir = dirs::data_dir() + .unwrap_or_else(|| PathBuf::from(".")) + .join("aof") + .join("sessions"); +tokio::fs::create_dir_all(&persist_dir).await?; +let session_persistence = SessionPersistence::new(persist_dir.clone()).await?; + +// Generate session ID (UUID v4, unique per daemon lifetime) +let session_id = uuid::Uuid::new_v4().to_string(); +println!(" Session ID: {}", session_id); + +// Restore previous session if exists (for debugging/continuity) +// In Phase 1, just log if previous session exists +if let Ok(sessions) = session_persistence.list_sessions().await { + if !sessions.is_empty() { + println!(" Found {} previous session(s)", sessions.len()); + } +} +``` + +3. Pass event_bus to TriggerServerConfig: +```rust +let server_config = TriggerServerConfig { + bind_addr, + enable_cors: config.spec.server.cors, + timeout_secs: config.spec.server.timeout_secs, + max_body_size: 10 * 1024 * 1024, + event_bus: Some(event_bus.clone()), +}; +``` + +4. Update the startup message: +```rust +println!(" WebSocket: ws://{}/ws", bind_addr); +``` + +5. Save session state on shutdown: +```rust +// In the shutdown handler, before "Server stopped gracefully": +let final_state = SessionState { + session_id: session_id.clone(), + agent_states: std::collections::HashMap::new(), // TODO: Collect from runtime in Phase 2+ + task_queue: Vec::new(), + created_at: chrono::Utc::now(), + last_updated: chrono::Utc::now(), +}; +if let Err(e) = session_persistence.save_session(&final_state).await { + eprintln!("Warning: Failed to save session state: {}", e); +} +println!(" Session state saved"); +``` + +6. Pass event_bus to Runtime/TriggerHandler so agents can use it. When creating the Runtime, inject the event_bus: +```rust +// When setting handler.set_runtime(), also store event_bus for agent execution +// The exact mechanism depends on how TriggerHandler creates AgentExecutors +// For now, store event_bus in a place TriggerHandler can access +handler.set_event_bus(event_bus.clone(), session_id.clone()); +``` + +This requires adding a `set_event_bus` method to TriggerHandler. Add to aof-triggers handler: +```rust +pub fn set_event_bus(&mut self, event_bus: Arc, session_id: String) { + self.event_bus = Some(event_bus); + self.session_id = Some(session_id); +} +``` + +And when TriggerHandler creates an AgentExecutor for incoming messages, pass the event_bus through: +```rust +let executor = AgentExecutor::new(config, model, tool_executor, memory) + .with_event_bus(self.event_bus.clone().unwrap(), self.session_id.clone().unwrap()); +``` + +NOTE: The exact TriggerHandler -> AgentExecutor wiring may need adaptation based on how TriggerHandler currently creates executors. Read the TriggerHandler source to understand the pattern. The key principle: event_bus flows from serve.rs -> TriggerHandler -> AgentExecutor. + +**IMPORTANT PITFALLS TO AVOID (from research):** +- WebSocket sender must be single-writer (split into sender/receiver, spawn single send task) +- Handle `RecvError::Lagged` explicitly (log warning, continue) +- Handle client disconnect (break on send error) +- Use `tokio::fs` not `std::fs` for session persistence path creation + + +Run `cargo check -p aof-triggers` — compiles with new WebSocket support. +Run `cargo check -p aofctl` — compiles with event bus wiring. +Run `cargo check --workspace` — full workspace compiles. +Run `cargo test -p aof-triggers` — existing tests still pass. +Manual test: `cargo run --release -p aofctl -- serve --port 8080` should start and print WebSocket URL. +Manual test: If websocat is available, `websocat ws://localhost:8080/ws` should connect (receives no events until agent runs). + + +`aofctl serve` starts daemon with WebSocket server on /ws.

Producers emit events, multiple consumers subscribe without coupling. + +**When to use:** Real-time dashboards, multi-subscriber scenarios, audit trails. Perfect for Phase 1 (single daemon instance, <100 subscribers expected). + +**How it works:** +1. Daemon creates broadcast channel on startup +2.

Extend this for coordination instead of creating parallel event system. + +**When to use:** When existing infrastructure already tracks what you need. Prevents duplication and maintains consistency. + +**How:** +```rust +// In aof-core/src/coordination.rs (NEW FILE) +use crate::activity::{ActivityEvent, ActivityType}; +use serde::{Deserialize, Serialize}; +use chrono::{DateTime, Utc}; + +/// Coordination event wraps ActivityEvent with routing metadata +#[derive(Debug, Clone, Serialize, Deserialize)] +pub struct CoordinationEvent { + /// Underlying activity event + pub activity: ActivityEvent, + + /// Agent ID that emitted this event + pub agent_id: String, + + /// Session ID for grouping related events + pub session_id: String, + + /// Event ID for deduplication + pub event_id: String, +} + +impl CoordinationEvent { + pub fn from_activity(activity: ActivityEvent, agent_id: String, session_id: String) -> Self { + Self { + activity, + agent_id, + session_id, + event_id: uuid::Uuid::new_v4().to_string(), + } + } +} +``` + +**Why this works:** +- Reuses existing 21 activity types (Thinking, Analyzing, LlmCall, ToolExecuting, etc.) +- ActivityEvent already has timestamps, details, tool names +- Just adds routing metadata (agent_id, session_id) for control plane +- WebSocket clients get familiar event structure + +### Pattern 3: Daemon Mode Extends Serve Command + +**What:** AOF already has `aofctl serve` command (aofctl/commands/serve.rs) that starts long-running HTTP server for webhook triggers (Slack, Discord, GitHub, Jira). Extend this command to add WebSocket server on same port. + +**When to use:** When existing command already does 80% of what you need. Avoids new CLI surface area. + +**How:** +```rust +// In aofctl/commands/serve.rs (MODIFY EXISTING) + +// Current: Axum router with webhook routes +let app = Router::new() + .route("/webhook/:platform", post(handle_webhook)) + .route("/health", get(health_check)); + +// Extended: Add WebSocket route +let app = Router::new() + .route("/webhook/:platform", post(handle_webhook)) + .route("/ws", get(handle_websocket_upgrade)) // NEW + .route("/health", get(health_check)); + +// New handler +async fn handle_websocket_upgrade( + ws: WebSocketUpgrade, + State(state): State>, +) -> impl IntoResponse { + ws.on_upgrade(|socket| websocket_handler(socket, state.event_bus.clone())) +} + +async fn websocket_handler(socket: WebSocket, event_bus: Arc) { + let (mut sender, _receiver) = socket.split(); + let mut rx = event_bus.subscribe(); + + while let Ok(event) = rx.recv().await { + let json = serde_json::to_string(&event).unwrap(); + if sender.send(Message::Text(json)).await.is_err() { + break; // Client disconnected + } + } +} +``` + +**Benefits:** +- Single process, single port (8080) +- Reuses existing HTTP server infrastructure +- Health check endpoint works for both webhook and WebSocket +- Future: Can add HTTP API routes alongside WebSocket + +### Pattern 4: Session Persistence with Existing Memory Backends + +**What:** AOF has multiple memory backends (InMemoryBackend, FileBackend, optional Redis/Sled). Use FileBackend for session state persistence instead of building custom storage. + +**When to use:** When you need state to survive daemon restarts without complex database setup. + +**How:** +```rust +// In aof-coordination/src/persistence.rs (NEW) +use aof_memory::{SimpleMemory, MemoryBackend}; +use serde::{Deserialize, Serialize}; + +#[derive(Debug, Clone, Serialize, Deserialize)] +pub struct SessionState { + pub session_id: String, + pub agent_states: HashMap, + pub task_queue: Vec, + pub created_at: DateTime, + pub last_updated: DateTime, +} + +#[derive(Debug, Clone, Serialize, Deserialize)] +pub struct AgentState { + pub agent_id: String, + pub status: AgentStatus, + pub last_activity: DateTime, +} + +pub struct SessionPersistence { + memory: SimpleMemory, +} + +impl SessionPersistence { + pub async fn new(persist_path: PathBuf) -> Result { + let memory = SimpleMemory::file(persist_path).await?; + Ok(Self { memory }) + } + + pub async fn save_session(&self, state: &SessionState) -> Result<()> { + let json = serde_json::to_string(state)?; + self.memory.set(&state.session_id, json).await?; + Ok(()) + } + + pub async fn restore_session(&self, session_id: &str) -> Result> { + if let Some(json) = self.memory.get(session_id).await? { + let state: SessionState = serde_json::from_str(&json)?; + Ok(Some(state)) + } else { + Ok(None) + } + } +} +``` + +**Why this works:** +- FileBackend uses JSON storage (aof-memory/backend/file.rs) +- Automatic serialization through existing Memory trait +- No new storage abstraction needed +- Can swap to Redis/Sled later without changing interface + +### Anti-Patterns to Avoid + +- **Don't create parallel event system:** ActivityEvent already exists with 21 types. Extend it, don't replace it. +- **Don't use REST polling:** WebSocket push is the whole point. No `/events?since=timestamp` endpoints. +- **Don't block tokio runtime:** All file I/O must use `tokio::fs`, not `std::fs`. HTTP must use async clients. +- **Don't ignore slow consumers:** tokio::broadcast handles lagging subscribers by skipping events.

Buffer fills, old events discarded, consumer sees gaps. + +**Why it happens:** tokio::broadcast behavior — when buffer full, oldest message dropped, `RecvError::Lagged` returned. + +**How to avoid:** +- Set buffer size appropriately (1000 for Phase 1) +- Handle `RecvError::Lagged` explicitly (log warning, continue) +- Add client-side filtering (agent_id, event_type) to reduce event rate +- Future: Add backpressure (drop low-priority events like Thinking when lagged) + +**Warning signs:** +- WebSocket clients report missing events +- High memory usage in daemon +- `RecvError::Lagged` in logs + +**Example fix:** +```rust +// ❌ Bad: Panics on lagged receiver +while let Ok(event) = rx.recv().await { + send_to_websocket(event).await?; +} + +// ✅ Good: Handles lagged consumer +loop { + match rx.recv().await { + Ok(event) => { + if send_to_websocket(event).await.is_err() { + break; // Client disconnected + } + } + Err(tokio::sync::broadcast::error::RecvError::Lagged(n)) => { + tracing::warn!("WebSocket client lagged, dropped {} events", n); + // Continue receiving, client will catch up + } + Err(tokio::sync::broadcast::error::RecvError::Closed) => { + break; // Channel closed, daemon shutting down + } + } +} +``` + +### Pitfall 4: Not Handling WebSocket Client Disconnects Gracefully + +**What goes wrong:** Client closes WebSocket, but server task keeps trying to send, panics or loops forever consuming CPU. + +**Why it happens:** WebSocket `send()` returns error on disconnect, but error handling missing or wrong. + +**How to avoid:** +- Check send result: `if sender.send(msg).await.is_err() { break; }` +- Spawn task per WebSocket connection, task exits on disconnect +- Use `tokio::select!` to listen for shutdown signal alongside event stream + +**Warning signs:** +- Zombie tasks after client disconnect +- Memory leak (tasks never cleaned up) +- CPU spike from infinite error loop + +**Example fix:** +```rust +// ❌ Bad: Ignores send errors +loop { + let event = rx.recv().await.unwrap(); + let _ = sender.send(Message::Text(json)).await; // Ignores error +} + +// ✅ Good: Exits on disconnect +while let Ok(event) = rx.recv().await { + let json = serde_json::to_string(&event)?; + if sender.send(Message::Text(json)).await.is_err() { + tracing::info!("WebSocket client disconnected"); + break; + } +} +``` + +### Pitfall 5: Forgetting to Clone Broadcast Sender Before Injecting + +**What goes wrong:** Pass broadcast sender directly to AgentExecutor. First agent consumes sender, second agent can't emit events. + +**Why it happens:** Broadcast sender is `Clone`, but easy to forget. Passing by value moves it. + +**How to avoid:** +- Wrap broadcast sender in Arc: `Arc` where EventBroadcaster holds sender +- Clone Arc before each injection: `runtime.with_event_bus(event_bus.clone())` +- Use newtype wrapper that forces Arc usage + +**Warning signs:** +- First agent emits events fine, second agent silently drops events +- Compile error: "value moved into closure" +- Events stop after first agent completes + +**Example fix:** +```rust +// ❌ Bad: Moves sender +let (tx, _rx) = tokio::sync::broadcast::channel(1000); +let executor1 = AgentExecutor::with_event_sender(tx); // tx moved +let executor2 = AgentExecutor::with_event_sender(tx); // Error: tx moved + +// ✅ Good: Arc wrapper +pub struct EventBroadcaster { + tx: tokio::sync::broadcast::Sender, +} + +impl EventBroadcaster { + pub fn new(tx: tokio::sync::broadcast::Sender) -> Self { + Self { tx } + } + + pub fn emit(&self, event: CoordinationEvent) { + let _ = self.tx.send(event); // Ignoring send errors is OK (no subscribers) + } + + pub fn subscribe(&self) -> tokio::sync::broadcast::Receiver { + self.tx.subscribe() + } +} + +let (tx, _) = tokio::sync::broadcast::channel(1000); +let event_bus = Arc::new(EventBroadcaster::new(tx)); + +// Clone Arc for each use +let executor1 = AgentExecutor::with_event_bus(event_bus.clone()); +let executor2 = AgentExecutor::with_event_bus(event_bus.clone()); +``` + +## Code Examples + +Verified patterns from existing AOF codebase and official Axum docs: + +### WebSocket Upgrade Handler (Axum) +```rust +// Source: Axum docs + aofctl/commands/serve.rs pattern +use axum::{ + extract::{State, ws::{WebSocket, WebSocketUpgrade}}, + response::IntoResponse, + routing::get, + Router, +}; + +async fn handle_websocket_upgrade( + ws: WebSocketUpgrade, + State(state): State>, +) -> impl IntoResponse { + ws.on_upgrade(|socket| websocket_handler(socket, state.event_bus.clone())) +} + +async fn websocket_handler(socket: WebSocket, event_bus: Arc) { + let (mut sender, mut receiver) = socket.split(); + let mut event_rx = event_bus.subscribe(); + + // Spawn task to forward events to WebSocket + let send_task = tokio::spawn(async move { + while let Ok(event) = event_rx.recv().await { + let json = serde_json::to_string(&event).unwrap(); + if sender.send(Message::Text(json)).await.is_err() { + break; + } + } + }); + + // Listen for client messages (ping/pong, close) + while let Some(Ok(msg)) = receiver.next().await { + match msg { + Message::Close(_) => break, + _ => {} // Ignore other messages for now + } + } + + send_task.abort(); // Clean up sender task +} +``` + +### Activity Event Emission (Existing Pattern) +```rust +// Source: aof-core/activity.rs + aof-runtime/executor/agent_executor.rs + +// In AgentExecutor::execute() (MODIFY EXISTING) +use aof_core::{ActivityEvent, ActivityType}; + +// Existing pattern: TUI activity logger +if let Some(ref logger) = self.activity_logger { + logger.log(ActivityEvent::thinking("Processing user request")); +} + +// New pattern: Coordination event bus (ADD THIS) +if let Some(ref event_bus) = self.event_bus { + let activity = ActivityEvent::thinking("Processing user request"); + let coord_event = CoordinationEvent::from_activity( + activity, + self.agent_id.clone(), + self.session_id.clone(), + ); + event_bus.emit(coord_event); +} +``` + +### Session Persistence (FileBackend Pattern) +```rust +// Source: aof-memory/backend/file.rs +use aof_memory::SimpleMemory; +use serde::{Deserialize, Serialize}; + +#[derive(Debug, Serialize, Deserialize)] +struct DaemonSession { + session_id: String, + started_at: DateTime, + agent_states: HashMap, +} + +// Initialize persistence +let session_store = SimpleMemory::file("./aof-session.json").await?; + +// Save session state +let session = DaemonSession { /* ... */ }; +let json = serde_json::to_string(&session)?; +session_store.set("current", json).await?; + +// Restore session state on daemon restart +if let Some(json) = session_store.get("current").await?

Event Format is Correct JSON +expected: | + Events received on WebSocket are valid JSON with structure: + - agent_id: string (UUID) + - session_id: string (UUID) + - event_id: string (UUID) + - timestamp: ISO 8601 string + - activity: object with type (started, info, tool_executing, etc.) and relevant fields +result: pass + +### 7. Documentation Explains Event Streaming +expected: | + User-facing documentation exists at docs/concepts/event-streaming.md with: + - Explanation of how to connect to the WebSocket + - JSON event format specification + - Code examples in JavaScript/Python/Rust + - At least one practical use case example +result: pass + +### 8.

Users must explicitly specify `provider: google` (or other provider) in YAML config to use alternative providers. + +2. **Event Bus Architecture Valid:** EventBroadcaster implementation correctly supports: + - Broadcast to multiple WebSocket clients + - Independent connection lifecycle per client + - Lagged consumer handling (warns but doesn't disconnect) + - Zero impact on default behavior when disabled + +3. **Session Persistence Working:** File-based persistence correctly saves and can restore: + - Unique session IDs (UUID v4) + - ISO8601 timestamps + - Agent state snapshots + - Task queue state + +### Readiness for Phase 2 + +**Prerequisites Met:** +- ✅ Event infrastructure foundation is stable and documented +- ✅ No breaking changes introduced to existing codebase +- ✅ Backward compatibility maintained for all existing CLI commands +- ✅ Event bus is truly optional (default behavior unchanged) +- ✅ Comprehensive documentation covers architecture, user concepts, and developer guidance + +**Ready to proceed to Phase 2 (Real Ops Capabilities)** + +--- + +*Phase 1 Event Infrastructure Foundation -

Sandbox Isolation + +### Current Practice + +**How do production systems isolate AI agent tool execution?** + +Sandbox isolation is critical for agent security. Industry approaches: + +**Docker Container Isolation:** +- Agents run tools inside ephemeral containers +- Container-per-tool or container-per-session +- Resource limits (CPU, memory, network) +- File system restrictions +- Credential access control via volume mounts + +**MicroVM Isolation (Firecracker, Kata Containers):** +- Stronger isolation than Docker (dedicated kernel per workload) +- Higher overhead (boot time, memory) +- Best for untrusted code execution +- Used by AWS Lambda, Fly.io + +**gVisor (User-space Kernel):** +- Application kernel in userspace +- Intercepts syscalls before reaching host kernel +- Lower overhead than microVMs +- Used by Google Cloud Run + +**Enhanced Container Isolation (Docker Desktop):** +- Linux user namespaces (map container root to unprivileged host user) +- Prevents container root = host root exploits +- File permission restrictions + +**OpenClaw Patterns (from Phase 2 context):** +- Host-level access for trusted operations +- Sandbox per session type or risk level +- Docker-based tool execution for untrusted tools +- File permissions restrict credential access + +**Common Vulnerabilities:** + +Recent CVEs (2025-2026): +- **CVE-2025-9074:** Docker Desktop container escape via unauthorized Engine access +- **n8n sandbox escape:** Code execution breaking out of n8n's JavaScript sandbox +- **Kernel vulnerabilities:** Shared kernel = attack surface for all containers + +### Trade-offs + +| Approach | Pros | Cons | +|----------|------|------| +| **Docker containers** | Simple, fast, good Rust support | Shared kernel, escape risk, credential exposure | +| **MicroVMs** | Strongest isolation, dedicated kernel | Slow boot, high memory, complexity | +| **gVisor** | User-space kernel, syscall filtering | Performance overhead, compatibility issues | +| **User namespaces** | Unprivileged container root | Requires host kernel support, some tools break | +| **File permissions** | Simple, no runtime overhead | Relies on correct permissions, human error risk | +| **seccomp profiles** | Syscall filtering, limits attack surface | May break tools, requires tuning | +| **Network policies** | Limit egress, prevent data exfiltration | Complexity, may break legitimate tools | + +### Recommendation for Phase 2 + +**Use Docker-based sandbox with defense-in-depth:** + +1. **Execution Model (adopt OpenClaw pattern):** + - **Trusted operations:** Run on host (kubectl with user's kubeconfig) + - **Untrusted tools:** Run in ephemeral Docker containers + - **Session isolation:** One container per agent session (reused for session lifetime) + - **Risk-based:** Low-risk (read-only) → host, High-risk (destructive) → sandbox + +2. **Docker Security Hardening:** + +**User Namespaces:** +- Map container root (UID 0) to unprivileged host user (UID 100000+) +- Prevents container root from becoming host root on escape + +**Resource Limits:** +```dockerfile +# Run container with limits +docker run \ + --memory=512m \ + --cpus=1.0 \ + --pids-limit=100 \ + --read-only \ + --tmpfs /tmp:size=100m \ + agent-sandbox:latest +``` + +**Seccomp Profile (restrict syscalls):** +```json +{ + "defaultAction": "SCMP_ACT_ERRNO", + "syscalls": [ + { "names": ["read", "write", "open", "close", "stat"], "action": "SCMP_ACT_ALLOW" }, + { "names": ["execve"], "action": "SCMP_ACT_ERRNO" } + ] +} +``` + +**Network Restrictions:** +- Default deny egress +- Whitelist allowed destinations (K8s API, Prometheus, Loki) +- No internet access for high-risk operations + +3. **Credential Access Control:** + +**File-level permissions:** +- Credentials stored with 600 permissions (owner-only read) +- Mount credentials read-only into container +- Agent-specific credential directories + +**Example:** +```bash +# Host: /var/aof/credentials/agent-001/ +# Contains: kubeconfig, aws-creds, etc. +# Mounted to container: /credentials/ (read-only) + +docker run \ + -v /var/aof/credentials/agent-001:/credentials:ro \ + --user 1000:1000 \ + agent-sandbox:latest +``` + +**Secret reference pattern (from existing `aof-core::context`):** +```yaml +apiVersion: aof.dev/v1 +kind: Context +metadata: + name: production +spec: + secrets: + - name: kubeconfig + path: /credentials/kubeconfig + mode: "0400" # Read-only for owner + - name: aws-creds + path: /credentials/aws + mode: "0400" +``` + +4. **Escape Prevention:** + +**Defense layers:** +1. **User namespaces** — Unprivileged container root +2. **Read-only root filesystem** — No binary modification +3. **Seccomp** — Syscall filtering (block dangerous calls) +4. **Resource limits** — Prevent DoS via resource exhaustion +5. **Network policies** — Egress filtering +6. **Audit logging** — Log all privileged operations + +**Monitoring:** +- Log all container starts/stops +- Alert on unusual syscalls (via seccomp) +- Track credential access (audit logs) +- Monitor escape indicators (privilege escalation attempts) + +5. **Session Trust Boundaries:** + +From OpenClaw: +- **Session types:** dev (low trust) vs prod (high trust) +- **Risk levels:** read-only (low) vs write (medium) vs destructive (high)

Squad broadcasts enable one-to-many communication patterns (e.g., "Deploy starting in 5 minutes" → all agents in all channels). The configuration system is extended to support squad definitions with agent mappings and multi-channel routing. Finally, the gateway is integrated into `aofctl serve` so users can start the gateway alongside the agent runtime. + +**Key deliverables:** +- Squad configuration schema (agent mappings, channel subscriptions) +- Squad announcement broadcast logic (route to all/specific agents/teams) +- Enhanced YAML schema with squad support +- Secrets management (environment variable substitution with validation) +- Integration with `aofctl serve` (load config, spawn adapters, connect to hub) +- CLI flags for gateway: `--gateway-config`, `--debug-gateway` +- 5-8 integration tests (config loading, squad broadcast, message flow) +- User documentation: gateway configuration guide + troubleshooting + +This plan depends on 03-01-PLAN (hub, config schema, adapters trait) but can run in parallel with 03-02-PLAN (platform adapters implementation is not required for this work). + +## Architecture Context + +### Squad Broadcast Patterns + +**Use cases:** +1. **All-hands broadcast:** "Deploy starting in 5 minutes" → all agents in all channels +2. **Team-specific:** "Incident SEV1 detected" → ops-team agents only +3. **Channel-specific:** Slack #incidents → only agents monitoring that channel + +**Broadcast flow:** +``` +Agent/Human → BroadcastMessage → Gateway Hub → Squad Resolution + ↓ + ┌──────────────────┴──────────────────┐ + │ │ + Slack Adapter Discord Adapter + │ │ + Channel A, Channel B Channel C, Channel D +``` + +### Squad Configuration + +```yaml +squads: + - name: ops-team + description: "Operations team agents" + agents: + - "k8s-monitor" + - "incident-responder" + - "log-analyzer" + channels: + slack: "C01234567" # #ops-team + discord: "987654321098765432" # ops-team channel + telegram: "-1001234567890" # ops-team group + + - name: dev-team + description: "Development team agents" + agents: + - "code-reviewer" + - "ci-cd-manager" + channels: + slack: "C98765432" + discord: "123456789012345678" +``` + +### Integration with aofctl serve + +The gateway runs alongside the agent runtime: +```bash +# Start agent runtime with gateway +aofctl serve --gateway-config gateway.yaml --debug-gateway + +# Gateway connects to runtime via WebSocket (Phase 1 infrastructure) +# - Receives messages from platforms → routes to agents +# - Receives agent responses → routes to platforms +``` + +## Tasks + + + Define Squad configuration schema + + Extend configuration schema in `config.rs` to support squad definitions. + + Add to GatewaySpec: + ```rust + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct GatewaySpec { + pub runtime: RuntimeConfig, + pub adapters: Vec, + pub squads: Vec, // NEW + } + + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct SquadConfig { + /// Squad name (unique identifier) + pub name: String, + /// Human-readable description + pub description: String, + /// Agent IDs in this squad + pub agents: Vec, + /// Platform channel mappings + pub channels: SquadChannels, + } + + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct SquadChannels { + pub slack: Option, // Channel ID (C...) + pub discord: Option, // Channel ID (numeric) + pub telegram: Option, // Chat ID (numeric or -...) + pub whatsapp: Option, // Phone number (future) + } + ``` + + Validation rules: + - Squad names must be unique within config + - Agent IDs should reference existing agents (warn if not found, don't fail) + - Channel IDs must be non-empty strings if present + - At least one channel must be configured per squad + + Helper functions: + ```rust + impl GatewayConfig { + /// Get squad by name + pub fn get_squad(&self, name: &str) -> Option<&SquadConfig>;

The gateway acts as a central control plane with platform-specific channel adapters that normalize message format, threading, and rich media differences into a standard `CoordinationEvent` format. The recommended approach follows OpenClaw's proven hub-and-spoke architecture: a single Gateway owns all messaging channels and communicates with agents via the existing WebSocket/broadcast channel infrastructure from Phase 1. + +**Primary recommendation:** Create `aof-gateway` crate with a hub-and-spoke control plane using platform-specific adapters (`slack-morphism` for Slack, `serenity` for Discord, `teloxide` for Telegram). Use NAT-transparent outbound WebSocket connections (Slack Socket Mode, Discord Gateway WebSocket) to eliminate ngrok dependency. Implement per-platform rate limiting with the `governor` crate (GCRA algorithm, async-ready). Normalize all platform messages to `CoordinationEvent`, then route to agent runtime via existing tokio::broadcast channel. + +**Key insight from OpenClaw:** The hub-and-spoke model with a single Gateway owning all messaging surfaces (WhatsApp, Telegram, Slack, Discord, Signal, iMessage) provides a clean separation between messaging channels and agent execution, enabling multi-channel access while maintaining security boundaries and persistent sessions. + +## Architecture Pattern: Hub-and-Spoke Gateway + +### Overview + +The hub-and-spoke pattern uses a central control plane (Gateway) with platform-specific adapters (spokes) that translate platform quirks into a standard message format.

Rate Limiting: Token Exhaustion + +**Problem:** High message volume exhausts rate limit tokens, messages queue up. + +**Mitigation:** +- Implement backpressure: Return 429 to agents if gateway queue full +- Priority queuing: Urgent messages skip queue +- Adaptive rate limiting: Reduce agent activity when rate limit approached + +```rust +if rate_limiter.check().is_err() { + warn!("Rate limit exhausted, queuing message"); + message_queue.push(message); + + // Notify agent runtime to slow down + gateway.emit_backpressure_event().await; +} +``` + +### 6. Threading Context Loss + +**Problem:** Platforms differ in threading semantics.

Install dependencies: react, react-dom, vite, @vitejs/plugin-react. Install builder.io: @builder.io/react, @builder.io/sdk. Install state management: @reduxjs/toolkit, react-redux. Install UI framework: shadcn/ui, @radix-ui/primitive, tailwindcss, postcss. Install WebSocket client: ws (for TypeScript types), use native WebSocket API. Install dev tools: typescript, @types/react, @types/node, eslint. Create folder structure: src/{components,hooks,store,types,utils}, public/, dist/. + + + Running `npm run dev` starts server at localhost:5173 without errors. `npm run build` completes without warnings. package.json contains all dependencies with pinned versions. vite.config.ts configured with @vitejs/plugin-react and proper TypeScript setup. tsconfig.json has strict: true, lib includes ["ES2020", "DOM", "DOM.Iterable"]. .gitignore excludes node_modules/, dist/, .env.local. + + + + + Set up Redux store with eventsSlice and configSlice + + Create src/store/index.ts that exports configureStore from redux toolkit. Create src/store/eventsSlice.ts with initial state containing events: CoordinationEvent[], lastEventId: string, connected: boolean. Add reducers: addEvent (appends to array, keeps last 500), clearEvents (resets), setConnected (sets boolean). Export actions and reducer. Create src/store/configSlice.ts with initial state containing agents: Agent[], tools: Tool[], configVersion: string. Add reducers: setAgents, setTools, setConfigVersion. Create src/types/events.ts with TypeScript interfaces: CoordinationEvent (matching Phase 1 schema), Agent, Tool. Ensure all types match Phase 1 CoordinationEvent structure from research. + + + Redux DevTools Browser Extension works and shows store state. Dispatching addEvent action appears in DevTools with payload. eventsSlice.reducer registered in store. configSlice.reducer registered in store. Type imports in React components compile without errors. No TypeScript errors in store files. + + + + + Create useWebSocket hook with automatic reconnection and exponential backoff + + Create src/hooks/useWebSocket.ts with React hook that accepts url parameter. Implement WebSocket connection with onopen, onmessage, onerror, onclose handlers. Implement exponential backoff: 1s, 2s, 4s, 8s, 16s, 30s cap. Track retry count with ref. Parse incoming JSON as CoordinationEvent. Return { connected: boolean, lastEvent: CoordinationEvent | null, reconnectAttempts: number }. Dispatch action to Redux store (useDispatch hook) for each event received and connected state change. Handle network errors gracefully with console.error. Cleanup WebSocket on unmount. + + + Hook compiles without errors. Manual test: webpack-dev-server running, open DevTools, import useWebSocket in dummy component, observe WebSocket connection attempt in Network tab. If server at :8080/ws not ready, hook reconnects automatically with delays. Closing DevTools network to simulate disconnect triggers reconnection. Incoming event appears in console and Redux DevTools. No memory leaks detected in React DevTools Profiler. + + + + + Create App.tsx with WebSocket subscription and Redux integration + + Create src/App.tsx as main component. Import useWebSocket hook, useDispatch, useSelector. Render layout with three sections: header (showing connection status), main (placeholder for future panels), sidebar (event log). Call useWebSocket('ws://localhost:8080/ws') on mount. Subscribe to Redux store events using useSelector. Map events to list items in activity log (display last 20 events). Show connection status indicator (green if connected, red if disconnected, yellow if reconnecting). Render Redux store statistics (total events received, last event timestamp). Add Vite HMR setup in dev mode for instant reload. + + + Page loads at localhost:5173. Header shows "Connecting..." initially, then "Connected" after WebSocket opens. Network tab shows ws://localhost:8080/ws connection attempt. Activity log receives events and displays them. Redux DevTools shows eventsSlice state growing. Page refreshes trigger new connection. No JavaScript errors in console. + + + + + Add configuration API client hooks (useAgentsConfig, useToolsConfig) + + Create src/hooks/useAgentsConfig.ts that fetches http://localhost:8080/api/config/agents on mount. Handle loading, error, success states. Cache response with version tracking from X-Config-Version header. Return { agents: Agent[], version: string, loading: boolean, error: Error | null }. Implement refetch function. Create src/hooks/useToolsConfig.ts with same pattern for tools endpoint. Implement polling loop that checks /api/config/version every 10 seconds (placeholder implementation, returns version mismatch only in dev). If version changed, trigger refetch. Show "Loading config..." UI while fetching. Implement error fallback that renders empty list instead of crashing. + + + useAgentsConfig hook renders without errors. Initially shows loading state. Network tab shows GET request to /api/config/agents. If endpoint returns 404, hook shows error state gracefully. If endpoint returns empty array (default from Phase 1), hook renders empty state. Version polling does not spam console errors. Refetch manually callable without side effects. + + + + + Configure Vite proxy and CORS for localhost development + + Update vite.config.ts with server.proxy configuration: proxy /api/* and /ws/* requests to http://localhost:8080. Set changeOrigin: true. Add server.cors: true. Configure devServer.hot for HMR. Test that localhost:5173 can reach localhost:8080 without CORS errors. In src/hooks/useWebSocket.ts, construct URL dynamically (dev: ws://localhost:8080/ws, prod: ws://location.host/ws). Add .env.local template with VITE_API_URL=http://localhost:8080. + + + Browser DevTools Network tab shows /api/config/agents proxied to localhost:8080. WebSocket shows ws://localhost:8080/ws in Network panel. No CORS errors in console. API calls work without preflight requests. Production build uses relative URLs (location.host). + + + + + Add Tailwind CSS and shadcn/ui component setup + + Install tailwindcss, postcss, autoprefixer. Create tailwind.config.js with content paths including src/**/*.{tsx,ts}. Create postcss.config.js with tailwindcss plugin. Import Tailwind directives in src/main.tsx or separate styles.css. Install shadcn/ui CLI: npx shadcn-ui@latest init. Run initialization to add components directory. Add base UI components: Button, Card, Input, Select, Badge, Tabs. Create src/components/StatusIndicator.tsx to render agent/connection status with color coding. Ensure all shadcn/ui components use Tailwind classes for consistency. + + + `npm run dev` compiles Tailwind without warnings. Tailwind classes render properly in browser (inspect element shows computed styles). shadcn/ui components install without errors. StatusIndicator component renders with proper colors (green/yellow/red). Build includes Tailwind CSS (<50KB gzipped). + + + + + Create TypeScript types for Phase 1 CoordinationEvent and extended schemas + + Create src/types/events.ts with interfaces: CoordinationEvent (with event_id, agent_id, activity: {type, details}, timestamp), AgentActivity (enum or union of activity types: AgentStarted, AgentCompleted, ToolCalled, etc.), AgentStatus (enum: idle, working, blocked, error). Create src/types/config.ts with Agent interface (id, name, role, personality, avatar, skills: string[], status: AgentStatus), Tool interface (name, description, category, input_schema?, output_schema?). Create src/types/tasks.ts with Task interface (id, title, description, lane: 'backlog'|'assigned'|'in-progress'|'review'|'done', assignedTo?: string, version: number, createdAt, updatedAt). Ensure all types exported from centralized src/types/index.ts. Add JSDoc comments explaining each type. + + + All type files compile without errors. TypeScript strict mode enabled in tsconfig.json passes. React components can import types without circular dependencies. No type errors when using types in Redux slices. Type definitions match Phase 1 CoordinationEvent structure from research file. + + + + + Implement Vite build optimization and production configuration + + Configure vite.config.ts with build settings: target: 'ES2020', minify: 'terser', terserOptions with compress/mangle. Add vite-plugin-compression for gzip output analysis. Configure chunk size warnings (warn >500KB). Add sourcemap in dev, disable in prod. Create build script in package.json: "build": "vite build". Create analyze script: "build:analyze" to inspect bundle size. Set NODE_ENV=production for build. Configure .env files for dev/prod environment variables. Ensure dist/ is gitignored. + + + `npm run build` completes in <30 seconds. dist/ folder contains index.html, assets/ with .js and .css files. Total bundle size <500KB (gzipped). No build warnings. dist/index.html can be served as static files (test with `npx serve dist`). Source maps available in dev, not in prod. + + + + + Add developer documentation and setup instructions + + Create web-ui/README.md with sections: Setup (npm install, npm run dev), Project Structure (explain src/ folders), Redux Store (how to use, where to find slices), WebSocket Hook (how to use useWebSocket), Configuration API (how to fetch and cache), Building & Deployment (npm run build, static file serving). Create CONTRIBUTING.md with coding standards (TypeScript strict mode, no console.log in production, commit message format). Create .eslintrc.cjs with React/TypeScript rules. Add precommit hook setup instructions (optional). Document troubleshooting section: "WebSocket not connecting?" → "Check if aofctl serve is running at :8080", "CORS errors?" → "Check vite.config.ts proxy", "Events not appearing?" → "Check Redux DevTools, refresh page". Store this doc in .planning/docs/04-FRONTEND-DEV.md for long-term reference. + + + README.md is readable and complete. New developer can run `npm install && npm run dev` and have working app in <5 minutes. Troubleshooting section is helpful for common issues. CONTRIBUTING.md covers code style. Both files stored in appropriate locations (web-ui/README.md for project, .planning/docs/ for AOF docs). + + + +## Verification Steps + +### Step 1: Environment Setup +1.

Render card with: image/avatar at top (use emoji from config or default), agent name and role as title, personality quote as description, skills as badge array with dark background. Add StatusIndicator component showing agent status (from Redux eventsSlice, computed by selector), color-coded (green=idle, blue=working, yellow=blocked, red=error). Implement hovering effect to show tooltip with full personality and last activity timestamp. Use shadcn/ui Card component for consistent styling. Add onClick to open agent detail modal (placeholder for 04-03). + + + AgentCard component compiles without errors. When passed Agent object with avatar emoji, renders emoji in card. Skills render as visible badges. Status indicator shows correct color based on Redux state. Card is keyboard accessible (Tab to focus, Enter to open details). No console warnings about missing props or type mismatches. Snapshot test passes (visual regression unlikely with shadcn/ui). + + + + + Create AgentGrid component that fetches and renders agent list + + Create src/components/AgentGrid.tsx that uses useAgentsConfig hook from 04-01. Fetch agents at mount, show loading skeleton. Render grid of AgentCard components (CSS Grid: grid-cols-1 sm:grid-cols-2 lg:grid-cols-4 xl:grid-cols-5). Map Redux agentStatus selector to each card (useSelector to get real-time status from eventsSlice). Implement polling for config version change (every 10s check /api/config/version). If version changed, refetch config. Show "Config updated, reloading..." toast notification briefly. Handle empty state (no agents) with helpful message. Handle error state (fetch failed) with retry button. + + + AgentGrid loads agents from useAgentsConfig hook. Initial state shows loading placeholders. On success, agents render in responsive grid (mobile: 1 col, tablet: 2 cols, desktop: 4-5 cols). Each card shows current status color (updates in real-time as Redux events arrive). Config version polling works without spamming requests. Refetch on version mismatch adds new agent to grid. Page responsiveness maintained on mobile (no overflow). + + + + + Set up Redux tasksSlice with optimistic updates and version tracking + + Create src/store/tasksSlice.ts with initial state: { tasks: {backlog: [], assigned: [], in-progress: [], review: [], done: []}, optimisticTasks: {...}, pending: Map }. Add reducers: updateTaskLaneOptimistic (moves task in optimisticTasks immediately), commitTaskLaneUpdate (syncs optimisticTasks to tasks when server confirms), rollbackTaskLaneUpdate (restores from tasks), setTasks (batch load from server). Add middleware to handle server events (TASK_UPDATED action): compare version, apply if server version > local version. Create selectors: selectTasksByLane (returns optimisticTasks for UI), selectTaskVersion (returns version of task for conflict detection). Ensure tasks have shape: {id, title, description, lane, assignedTo, version, createdAt, updatedAt, status}. + + + tasksSlice compiles without errors. Dispatching updateTaskLaneOptimistic moves task in state immediately. Redux DevTools shows three state slices: tasks (server truth), optimisticTasks (UI state), pending (tracking in-flight requests). Selectors return correct lane subsets. Version field present in task structure. Type safety with TypeScript—no `any` types in reducer payloads. + + + + + Create TaskCard component with drag handle and visual indicators + + Create src/components/TaskCard.tsx as functional component accepting Task prop. Use dnd-kit's useSortable hook with task.id as draggable ID. Render card with: title, description (truncate at 2 lines), assigned avatar/name (if assignedTo set), status badge color-coded, version number (small gray text). Add drag handle icon (::before pseudo-element or DragHandle icon from @dnd-kit). Implement visual feedback during drag: opacity 0.5, shadow effect. Use CSS.Transform from @dnd-kit/utilities for smooth animations. Add border color that changes based on task status (green=done, orange=in-progress, gray=backlog). Make card keyboard accessible: role="button", tabIndex={0}, aria-label with task title and lane. + + + TaskCard component compiles. When rendered in dnd-kit context, drag handle appears and is interactive. Dragging task shows opacity change and shadow. Drop completes without console errors. Task card dimensions consistent across lanes (no layout shift). Keyboard navigation: Tab selects card, Enter would open detail (in 04-03). Typography renders cleanly (no text overflow). + + + + + Create Lane component with drop zone and empty state + + Create src/components/Lane.tsx functional component accepting laneId (string) and tasks (Task[]) as props. Use dnd-kit's useDroppable hook to make lane a drop target. Render lane container with: header showing lane name and task count badge (use semantic HTML counter). Implement SortableContext with items={tasks.map(t => t.id)} and verticalListSortingStrategy. Render space for tasks below header. If tasks.empty, show empty state "No tasks in {lane}" with helpful icon. Add CSS styling: min-height: 500px, bg-gray-50, border rounded, consistent width. On drop, don't handle event (parent handles in KanbanBoard). Color-code lane header background (backlog=slate, assigned=blue, in-progress=orange, review=yellow, done=green). + + + Lane component renders without errors. Lane header shows correct count (updates when tasks array changes). Empty state appears when tasks.length === 0. Drop zone is visually distinct (different background color). Droppable state detected by dnd-kit (can see isOver state if needed). Lane height sufficient to show tasks without overflow. Responsive width on mobile (lanes scroll horizontally or stack). + + + + + Integrate dnd-kit and implement drag-and-drop with optimistic updates + + Create src/components/KanbanBoard.tsx that uses dnd-kit's DndContext. Initialize DndContext with sensors: [PointerSensor, TouchSensor, KeyboardSensor]. Set collisionDetection to closestCorners. Implement handleDragEnd callback: extract active.id (taskId) and over.id (newLaneId). Dispatch updateTaskLaneOptimistic immediately (optimistic update). Send POST /api/tasks/move with {taskId, newLaneId, currentVersion}. On success (200): dispatch commitTaskLaneUpdate. On failure (409 Conflict): dispatch rollbackTaskLaneUpdate and show toast "Task moved by another user, rolling back". On other errors (5xx): show toast "Network error, retrying..." and retry with exponential backoff. Render 5 Lane components horizontally (grid-cols-5 on desktop, scroll on mobile). Use useSelector to get optimisticTasks (rendered state) and tasks (server truth). + + + KanbanBoard renders without errors. Dragging task between lanes shows instant visual feedback (optimistic move). Releasing task triggers POST request visible in Network tab. Successful request updates Redux state (commitTaskLaneUpdate). Failed request rolls back task to original lane with user notification. Drag handle accessible via keyboard and mouse. No layout shift during drag. Mobile view has horizontal scroll for lanes. Concurrent drags by multiple users handled (later conflict via version check). + + + + + Create useTaskManagement hook for API integration and state sync + + Create src/hooks/useTaskManagement.ts hook that returns {tasks, loading, error, moveTask, refetchTasks}. Implement moveTask(taskId, newLane, currentVersion) that: dispatches optimistic update, sends POST /api/tasks/move, handles success/failure/conflict. Implement refetchTasks() that fetches GET /api/tasks, dispatches setTasks. Add error handling: if 409 Conflict (version mismatch), log version info and emit conflict event. If 5xx, retry with exponential backoff (max 3 retries). Track pending requests with AbortController to cancel on unmount. Return loading state true during fetch, false after. Return error state with user-friendly message (fallback to generic "Something went wrong"). + + + useTaskManagement hook compiles without errors. moveTask function callable and triggers optimistic update. Fetch requests appear in Network tab. Conflict handling shows in console (version comparison logged). No memory leaks on unmount (AbortController cancels in-flight requests). Error state readable in component. Loading state transitions properly (loading→success or loading→error). + + + + + Implement version-based conflict resolution for concurrent task updates + + Add to tasksSlice reducer: handleServerTaskUpdate action that compares newTask.version > existingTask.version. If newer, merge server state. If older or equal, ignore (optimistic is ahead). Create selector selectTaskVersion(taskId) to get current version. On handleDragEnd, include currentVersion in POST body: {taskId, newLane, version}. On server response, if version matches, accept update. If version in response > version sent, merge response (server did other updates). Create unit test: start with task version 3, drag update sends version 3, server response is version 4 (another update happened), apply version 4 to state. + + + taskSlice handles version comparison correctly. Redux DevTools shows version field in task state. Unit test passes: task with version 3 receives version 4 from server, version 4 applied to Redux state. No type errors in version comparison logic. Conflict resolution documented in code with comments explaining version semantics. + + + + + Add accessibility features: keyboard navigation, ARIA labels, screen reader support + + Update TaskCard, Lane, and KanbanBoard components with: role="button" or role="region" as appropriate. Add aria-label to each task: "{title}, in {lane} lane, version {version}". Add aria-describedby to expand with description and assignee. Implement keyboard navigation: Tab moves focus between tasks, Arrow keys move task within lane (requires dnd-kit KeyboardSensor setup). Test with screen reader (VoiceOver on macOS or NVDA on Windows). Ensure status badges have aria-label (e.g., "status: in progress"). Add aria-live="polite" to activity notifications (moved task → "{title} moved to {lane}"). Document keyboard shortcuts in component or help modal. + + + All components have appropriate ARIA roles and labels. Screen reader test (NVDA or VoiceOver) reads task titles, lanes, and status. Keyboard navigation works: Tab cycles through tasks, can move task with keyboard. No redundant aria-labels (no labeling twice). WCAG 2.1 AA compliance verified (contrast ratios, focus indicators visible). + + + + + Install and configure dnd-kit library with TypeScript support + + Run: npm install @dnd-kit/core @dnd-kit/sortable @dnd-kit/utilities @dnd-kit/modifiers. Install types: npm install --save-dev @types/dnd-kit__core. Create src/utils/dndConfig.ts exporting DND_CONTEXT configuration object (sensors, collision detection, modifiers). Import in KanbanBoard. Test basic drag: render mock TaskCard in dnd-kit context, verify mouse/touch/keyboard events trigger drag callbacks. Verify no console warnings about missing provider or sensor initialization. + + + dnd-kit packages install without conflicts. npm list shows dnd-kit versions (should be latest minor versions). src/utils/dndConfig.ts exports valid DND_CONTEXT config. Importing DND_CONTEXT in KanbanBoard and using doesn't error. Drag gestures work: mouse (PointerSensor), touch (TouchSensor), keyboard (KeyboardSensor). No TypeScript errors in dnd-kit imports. + + + + + Add visual feedback, animations, and loading states + + Implement CSS transitions on TaskCard: transform 200ms cubic-bezier (smooth drag), opacity 150ms (fade on hover). Add shadow depth during drag (box-shadow elevated). On drag over lane, add visual indicator (border dashed, bg tint). Implement React Suspense + React.lazy() for AgentGrid and KanbanBoard to show skeleton loaders. Create Skeleton component using shadcn/ui Skeleton that matches card dimensions. Show skeleton for 1-2 seconds while loading tasks from API. On refetch, show "Refreshing..." toast (shadcn/ui Toast component). Implement loading spinner on POST /api/tasks/move request (disable lane buttons during request). + + + Dragging TaskCard shows smooth animation, no janky jumps. Drag-over state visually distinct (lane highlights or border changes). Loading states render skeleton placeholders. Task move POST shows loading indicator while in flight. Animations perform well (60fps, visible in React DevTools Profiler). No layout shift during animations (use transform instead of position changes). + + + + + Create integration tests for kanban board and document component API + + Write integration test using Vitest + React Testing Library: render KanbanBoard with mock tasks in different lanes, simulate drag from Backlog to In-Progress, verify Redux state updates optimistically, verify POST request sent, verify rollback on error. Test version conflict: task version 3 in state, server response version 5, verify version 5 applied. Test empty state: zero tasks, verify "No tasks" message visible in all lanes. Document component API in JSDoc comments: AgentCard props, Lane props, TaskCard props, KanbanBoard handlers. Store component documentation in .planning/docs/04-COMPONENTS.md for long-term reference. + + + Integration tests run with `npm test` and pass. Vitest configuration in vite.config.ts includes test settings. Coverage report shows >80% coverage for kanban-related code. JSDoc comments present in all components (visible in IDE autocomplete). .planning/docs/04-COMPONENTS.md exists and documents all component props, state, event handlers. + + + +## Verification Steps + +### Step 1: Agent Grid Rendering +1. Start Phase 1: `cargo run -p aofctl -- serve --config serve-config.yaml` +2. Start web-ui dev server: `npm run dev` +3. Open http://localhost:5173 +4. Verify AgentGrid component loads agents from /api/config/agents +5. If backend has 3 test agents configured, verify 3 cards render in grid +6. Check agent names, roles, and skills visible +7. Verify status indicator shows color (should be idle/green if no events) + +### Step 2: Agent Status Updates +1. In another terminal, trigger agent event: `aofctl run agent --name k8s-monitor --task "Check pod health"` +2. Verify agent card status changes color (blue/working) +3. Hover over agent to see tooltip with last activity timestamp +4. Check Redux DevTools shows agentStatus update in eventsSlice +5. Trigger agent complete: verify status returns to idle (green) + +### Step 3: Kanban Board Drag-and-Drop +1. Verify KanbanBoard renders with 5 lanes (Backlog, Assigned, In-Progress, Review, Done) +2. Verify task cards visible in appropriate lanes (fetch from /api/tasks) +3. Drag task from Backlog to In-Progress +4. Verify instant visual feedback (task moves immediately) +5. Check Network tab: POST /api/tasks/move request sent with {taskId, newLane, version} +6. Verify task persists in In-Progress after server response (200 OK) +7. Refresh page: verify task still in In-Progress (persisted to backend) + +### Step 4: Optimistic Update Rollback +1. Artificially simulate server failure: modify fetch to return 500 +2. Drag task from In-Progress to Done +3. Verify task moves visually (optimistic) +4. Verify POST request fails (500 error in Network tab) +5. Verify task rolls back to In-Progress lane (shows toast "Network error") +6. Check Redux DevTools shows rollbackTaskLaneUpdate action +7. Restore normal fetch, retry drag + +### Step 5: Version Conflict Resolution +1. Set up scenario: two browser windows, same kanban +2. Window A: drag task from Backlog to In-Progress (version increments 1→2) +3. Window B: simultaneously drag same task from Backlog to Done +4. Window A receives response version=2 (applied) +5. Window B receives response version=3 (conflict detected, version 3 > 2) +6. Verify Window B state shows version 3 applied (merged server state) +7. Refresh both windows: verify both show task in Done lane (version 3) + +### Step 6: Keyboard Navigation +1. Open page, focus first task (Tab) +2. Verify focus indicator visible (blue outline on task card) +3. Verify screen reader announces task title and lane +4. Press Enter (simulate drag, opens detail in 04-03) +5. Arrow keys move focus between tasks in lane +6. Verify no focus loss or jumps + +### Step 7: Mobile Responsiveness +1. Open DevTools responsive design mode (mobile view: 375px width) +2. Verify lanes stack or scroll horizontally +3. Verify task cards remain readable +4. Verify drag-and-drop works on touch (drag task, verify move) +5. Verify no overflow or layout shift on mobile + +### Step 8: Performance & Bundle Size +1. Run `npm run build` +2. Measure bundle: `du -sh dist/assets/` +3. Verify total increase from 04-01 is <150KB (dnd-kit + tasks code) +4. Run React DevTools Profiler: drag task 10 times +5. Verify re-renders optimized (only affected tasks/lanes re-render) +6. Check memory usage doesn't spike during drag (60-80MB on desktop) + +## Must-Haves + +1. **Agent cards render from workspace config, not hardcoded** - /api/config/agents is fetched at startup, agents render dynamically. Adding new agent to workspace config refetches automatically (version check polls every 10s). + +2. **Kanban board fully functional** - 5 lanes (Backlog, Assigned, In-Progress, Review, Done), tasks move via drag-and-drop, POST /api/tasks/move called, state persists after page refresh. + +3. **Optimistic updates + version-based conflict resolution** - Drag shows instant feedback, task moves in UI before server responds. If concurrent updates occur, version comparison applied (higher version wins). + +4. **No hardcoding of agent data or task data** - All agent info comes from API (/api/config/agents), all task info comes from API (/api/tasks or events). No static arrays in React components. + +5. **Accessibility compliant** - ARIA labels on all interactive elements, keyboard navigation works (Tab/Arrow/Enter), screen reader can announce task status and lane, focus indicators visible. + +## Dependencies + +### What 04-01 Provides +- React + Vite scaffolding +- Redux store with eventsSlice +- useWebSocket hook +- useAgentsConfig and useToolsConfig hooks +- TypeScript types for CoordinationEvent and Agent + +### What 04-02 Establishes for Later Plans +- tasksSlice for managing task state (used in 04-03 for task detail modal) +- TaskCard component (reused in task detail timeline in 04-03) +- useTaskManagement hook (used in 04-04 for API integration) +- DnD configuration and patterns (reused if other drag-drop features added) +- Component documentation (referenced when onboarding new developers) + +### What Phase 1 Provides +- /api/config/agents endpoint (returns Agent[] JSON) +- /api/config/tools endpoint (returns Tool[] JSON) +- /api/config/version endpoint (returns version string for cache invalidation) +- /api/tasks endpoint (returns Task[] JSON) - **Must be implemented in Phase 1 before 04-02 merge** +- POST /api/tasks/move endpoint (accepts {taskId, newLane, version}, returns updated Task with new version) + +## Notes + +- **builder.io Integration:** 04-02 uses standard React components (AgentCard, TaskCard, Lane). builder.io templates can wrap these components in 04-02 or be integrated later.

Add ChatMessage interface: {id, senderId, senderName, senderAvatar, content, timestamp, threadId?: string}. Add reducers: addMessage (appends to messages, dedupes by ID), setMessages (batch load from API), clearMessages, markAsRead, selectAgent. Add middleware/listener to handle CHAT_MESSAGE CoordinationEvent from WebSocket (parse event, dispatch addMessage). Implement message deduplication: if message.id already exists, skip append. Create selectors: selectMessagesByAgent (filter by senderId), selectUnreadMessages, selectMessagesSince (timestamp). + + + chatSlice compiles without errors. Redux DevTools shows chatSlice with messages array initialized empty. Dispatching addMessage with new ChatMessage appends to state. Duplicate addMessage with same ID is ignored (no duplicates in array). CHAT_MESSAGE event from WebSocket triggers addMessage reducer. TypeScript types strict. + + + + + Create ChatMessage and SquadChat components for message display and input + + Create src/components/ChatMessage.tsx showing: sender avatar (emoji or image), sender name, timestamp (relative time from date-fns), message content, optional reply count if threaded. Implement optional markdown rendering (use react-markdown with safe sanitization). Add hover state showing message actions (copy, delete if own message, reply). Use shadcn/ui Card for message styling. + + Create src/components/SquadChat.tsx with: message history viewport (scrollable, fixed height ~400px), input field with send button (disabled while loading), typing indicator when someone else is typing (optional Phase 2 feature). Use useDispatch to send messages: onClick send → dispatch addMessage optimistically → send POST /api/chat/messages → on success, version confirmed → on error, rollback. Subscribe to CHAT_MESSAGE events from Redux store (useSelector). Show "Loading messages..." during initial fetch. Implement virtual scrolling (react-window) if >100 messages for performance. + + + ChatMessage component renders message with avatar, name, timestamp, content. Markdown rendering works (if included). SquadChat component shows message history and input field. Clicking send button: message appears optimistically, POST request sent, Redux state updates on success. Old messages load on mount (if API ready). Component is keyboard accessible: Tab to input, Enter to send. No console errors on render. + + + + + Create activitiesSlice Redux reducer for event timeline + + Create src/store/activitiesSlice.ts with initial state: { activities: ActivityItem[], loading: false, error: null }. Define ActivityItem interface: {eventId, agentId, agentName, activityType, description, details: any, timestamp, icon: string}. Add reducers: addActivity (appends, keeps last 200), setActivities (batch load). Add middleware to subscribe to CoordinationEvent stream from Redux eventsSlice. For each event, create ActivityItem by mapping event.activity.type to human-readable description. Implement enum ActivityType with cases: AGENT_STARTED, AGENT_COMPLETED, TOOL_CALLED, TOOL_FAILED, TASK_ASSIGNED, TASK_MOVED, TASK_COMPLETED, MESSAGE_SENT, etc. Create selector selectActivitiesSince(timestamp) for incremental fetches. + + + activitiesSlice compiles without errors. CoordinationEvent arriving in Redux triggers ActivityItem creation. Activity appears in activities array. Last 200 rule maintained (array.length capped at 200). Each ActivityType has mapping to icon and description string. Redux DevTools shows activities updating in real-time as events arrive. No type errors. + + + + + Create ActivityFeed component with collapsible timeline items + + Create src/components/ActivityFeed.tsx that renders sorted list of ActivityItem objects from Redux activitiesSlice (newest first). Use shadcn/ui Accordion for expandable items (collapsed shows 1-line summary, expanded shows full details). Render: event icon, agent avatar, activity description, timestamp (relative). On expand, show details object as JSON or formatted table. Implement virtualization for large feeds (react-window or react-virtual). Color-code events by type (red=error, green=success, blue=agent-action, orange=task-change). Show "Loading activity..." during initial fetch. Auto-scroll to newest event on new event arrival (use useEffect with ref). + + + ActivityFeed component renders without errors. List shows activities in reverse chronological order (newest at top). Expanding item shows full details. Icons and colors render correctly based on ActivityType. Virtual scrolling works (scroll smoothly through 200 items). New events scroll into view automatically. No console warnings. Keyboard accessible: Tab to accordion, Space/Enter to expand. + + + + + Create TaskDetail modal component with full task context + + Create src/components/TaskDetail.tsx as modal/dialog component (shadcn/ui Dialog). Accept taskId prop. Fetch task details from Redux tasksSlice (or API GET /api/tasks/{id}). Display: title, full description, assigned agent with avatar, current status (with color badge), due date (if present), labels/tags, created date, updated date, version number. Render TabInterface (shadcn/ui Tabs) with tabs: Overview, Comments, History. Implement auto-refresh if task.version changes (means update on server, refetch). Include close button (Escape key, X button). On close, clear selection from Redux store. + + + TaskDetail modal compiles without errors. Opening modal by clicking task card displays modal. Task title, description, assignee visible. Status badge shows correct color. Modal closeable with Escape key or close button. No console errors during open/close. Task refetch triggered on version change. Tabs render without errors (content loaded on demand). + + + + + Create TaskTimeline tab showing status changes and history + + Create src/components/TaskTimeline.tsx to render in TaskDetail modal (History tab). Query activitiesSlice for all events related to task (filter by taskId). Sort chronologically (oldest first). Render timeline: vertical line with dots at each event. Each event shows: icon, activity type (TASK_CREATED, TASK_ASSIGNED, TASK_MOVED, TASK_COMPLETED), agent who triggered, timestamp. On hover, show full details. Alternate left/right layout (zigzag style) for visual interest. Implement keyboard navigation: arrow keys move between events, Space to expand details. + + + TaskTimeline compiles without errors. Renders related events for task in chronological order. Timeline visual layout clean and readable. Icons and colors render correctly. Hover shows details. Keyboard navigation works. No console errors. + + + + + Create Comments section with add/edit/delete comment functionality + + Create src/components/TaskComment.tsx showing single comment: author avatar, author name, comment text, timestamp, optional edit/delete buttons (if user owns comment). Support markdown rendering in comment text. Add reply functionality (optional Phase 2): clicking "Reply" opens reply input, nested under parent comment. + + Create Comments tab in TaskDetail modal that fetches comments from /api/tasks/{taskId}/comments (new API endpoint). Display comments sorted by timestamp. Add "Add comment" input at bottom (visible always). On submit: dispatch optimistic comment, send POST /api/tasks/{taskId}/comments with {text, version}, on success merge with Redux state, on error rollback. Support markdown in comment input (preview optional). Show "No comments yet" if empty. + + + TaskComment component renders comment with author, text, timestamp. Markdown renders correctly. Comments list in modal shows all comments. Add comment input visible, submit button functional. Optimistic comment appears immediately. Network request visible in DevTools. Edit/delete buttons visible for own comments (mock for now, server validation later). No console errors. + + + + + Implement real-time event subscription and state sync for all new components + + Update App.tsx layout to include SquadChat (right sidebar, fixed width), ActivityFeed (center-right panel, scrollable). Integrate useWebSocket hook from 04-01 (already dispatches events to Redux). Create Redux middleware in configureStore that: watches eventsSlice for new CoordinationEvent, dispatches appropriate reducers to chatSlice and activitiesSlice. For CHAT_MESSAGE events: dispatch addMessage to chatSlice. For agent/task events: dispatch addActivity to activitiesSlice. Ensure Redux middleware doesn't cause infinite loops (use action type guards). + + + App layout includes SquadChat and ActivityFeed components (positioned correctly). Redux middleware logs incoming events. CHAT_MESSAGE events trigger chatSlice updates. Agent events trigger activitiesSlice updates. No infinite loops in Redux (verified with Redux DevTools action history). Components update in real-time as events arrive. + + + + + Add timestamp formatting and relative time display with date-fns + + Install date-fns: npm install date-fns. Create src/utils/dateUtils.ts with helper functions: formatRelativeTime (returns "2 minutes ago"), formatTime (returns "14:30"), formatDate (returns "Feb 14"), formatDateTime (returns "Feb 14, 14:30"). Use in ChatMessage (timestamp), ActivityItem (timestamp), TaskComment (timestamp), TaskTimeline (timestamp). Handle timezone correctly (assume UTC from server, display in user's local timezone). Create test file src/utils/__tests__/dateUtils.test.ts with examples: current time returns "Just now", 1 hour ago returns "1 hour ago", etc. + + + date-fns installs successfully. dateUtils functions compile without errors. Unit tests pass (relative time formatting accurate). Components using formatRelativeTime show correct human-readable timestamps. Timezone conversion works (UTC from server → local browser time). + + + + + Implement message deduplication and chat history recovery on reconnect + + In useChatMessages hook (or chatSlice middleware): track lastChatMessageId from Redux state. On WebSocket reconnect (connection state changes from false → true in Redux), fetch /api/chat/messages?since={lastChatMessageId} to get messages sent during disconnect. Merge new messages into Redux state (deduped by message ID). For messages already in state, skip. Implement Optimistic Chat Message ID generation: client-side temporary ID (e.g., "temp_" + timestamp + random), server response includes real ID, merge on success. Update Redux state to replace temp ID with real ID. + + + useChatMessages hook compiles without errors. On WebSocket disconnect/reconnect cycle, chat history fetched and merged. No duplicate messages in Redux state (even if message appears both in memory and refetch). Temporary message IDs replaced with server IDs. No console errors during reconnect. Test: disconnect network, send message (stored in optimistic state with temp ID), reconnect, verify message persists with real ID. + + + + + Create integration tests and accessibility audit for chat and activity components + + Write Vitest integration test: render SquadChat, simulate CHAT_MESSAGE event arrival via Redux dispatch, verify message appears in UI. Render ActivityFeed, dispatch addActivity, verify activity item renders. Render TaskDetail modal, verify tabs functional. Test message dedup: dispatch same message twice, verify appears only once. Test accessibility: NVDA/VoiceOver reads message author, content, timestamp correctly. Verify keyboard navigation: Tab through messages, Shift+Tab backwards, Enter to expand activity details. Run axe accessibility scan (npm install --save-dev @axe-core/react, use in test). Document WCAG 2.1 AA compliance in .planning/docs/04-ACCESSIBILITY.md. + + + Integration tests run with `npm test` and pass. Test coverage >80% for chat/activity code. NVDA/VoiceOver audit shows all interactive elements announced correctly. Keyboard navigation fully functional. axe scan shows no violations (warnings OK).

Create crates/aofctl/src/api/config.rs with async functions: get_agents_config(), get_tools_config(), get_config_version(). Create crates/aof-core/src/config.rs with AgentConfig and ToolConfig structs (mirror of Agent and Tool types from web-ui TypeScript). Implement parsing functions: parse_agents_md(path: &str) -> Result, Error>, parse_tools_md(path: &str) -> Result, Error>. Use serde_yaml for parsing (already in Cargo.toml from Phase 1). Return serde_path_to_error formatted errors with exact field paths. Implement version hash: SHA256 of concatenated AGENTS.md + TOOLS.md content. + + + API module compiles without errors. config.rs exports parse_agents_md, parse_tools_md, version_hash functions. Test parsing: create sample AGENTS.md, call parse_agents_md, verify returns Vec with correct fields. Error handling: pass malformed YAML, verify serde_path_to_error shows field path. Version hash deterministic (same file = same hash). + + + + + Add Axum routes for config API endpoints + + Update crates/aofctl/src/commands/serve.rs to add three new routes to Axum Router: + - GET /api/config/agents → calls get_agents_config(), returns axum::Json> + - GET /api/config/tools → calls get_tools_config(), returns axum::Json> + - GET /api/config/version → calls get_config_version(), returns axum::Json<{version: string}> + Add X-Config-Version header to agents and tools responses (version string).

Add CORS headers: Access-Control-Allow-Origin: * (development), configurable in production. + + + Routes compile without errors. Axum Router includes three new GET handlers. Test: curl http://localhost:8080/api/config/agents returns valid JSON. Missing file returns []. Malformed YAML returns 400 with helpful error. Version header present in response. CORS headers set correctly (Access-Control-Allow-Origin present in response). + + + + + Implement static file serving for React build in Axum + + Update serve.rs to add static file serving. Accept command-line flag: --static-dir (default: ./web-ui/dist or relative to workspace root). Create middleware/handler that serves files from static-dir. Implement fallback: if file not found in static-dir and path doesn't start with /api or /ws, serve index.html (SPA routing). This allows React Router to handle client-side routes. Add Content-Type headers: .js → application/javascript, .css → text/css, .html → text/html. Add caching headers: Cache-Control: max-age=3600 for HTML (1 hour), max-age=31536000 for assets (1 year, hash-busted by Vite). Use axum::services::ServeDir for simple setup, or custom handler for fine-grained control. + + + Static file serving compiles without errors. Test: `cargo run -p aofctl -- serve --static-dir ./web-ui/dist` starts daemon. Open http://localhost:8080, verify index.html served. Navigate to /agents page (React route), verify index.html served (SPA routing preserved). Request /assets/main.abc123.js, verify JavaScript served with Cache-Control header. Request /missing-file, verify index.html served (not 404). No hardcoded paths. + + + + + Add command-line flags and configuration file support for serve command + + Extend aofctl serve command (in crates/aofctl/src/commands/serve.rs) to accept flags: --config (path to serve-config.yaml), --port (default 8080), --static-dir (default ./web-ui/dist), --workspace-root (default current directory). Parse command-line args with clap (already used in aofctl). Support YAML config file with same options (flags override config file). Example serve-config.yaml: + ```yaml + port: 8080 + workspace_root: /path/to/workspace + static_dir: ./web-ui/dist + ``` + Implement config loading with serde_yaml, use serde_path_to_error for helpful error messages. Validate paths exist (workspace_root, static_dir). Print loaded configuration on startup (debug mode). + + + Serve command compiles with clap integration. Test: `aofctl serve --port 9000` starts on port 9000. Test: `aofctl serve --config serve-config.yaml` loads config from file. Test: config file + flag override: config has port 9000, flag has --port 8000, verify flag wins. Error on invalid paths: --workspace-root /nonexistent, verify error message. Startup output shows loaded config (port, paths). + + + + + Implement file watcher for AGENTS.md and TOOLS.md auto-reload (optional feature) + + Create optional feature: add notify crate (file watcher) to Cargo.toml with feature flag "watch". Implement file watcher in serve.rs that monitors workspace_root/AGENTS.md and workspace_root/TOOLS.md. On file change: re-parse files, update in-memory cache, broadcast version change event to WebSocket subscribers (emit CONFIG_UPDATED event to all connected browsers). Browser receives event (Redux middleware), triggers config refetch. Disable watcher on --no-watch flag. In development (cargo run), watcher enabled by default. In production, can disable with flag. + + + Feature compiles with cargo build --features watch. Watcher detects file changes <500ms. On AGENTS.md change, CONFIG_UPDATED event broadcast to WebSocket subscribers. Browser receives event, triggers /api/config/agents refetch. New agent appears in UI. Test: edit AGENTS.md in editor, save, verify 2-3 second delay, UI updates. No file descriptor leaks (test with `lsof`). Can be disabled with flag. + + + + + Create Rust AgentConfig and ToolConfig types matching TypeScript schemas + + Define crates/aof-core/src/config.rs structs: + ```rust + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct AgentConfig { + pub id: String, + pub name: String, + pub role: String, + pub personality: String, + pub avatar: Option, + pub skills: Vec, + } + + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct ToolConfig { + pub name: String, + pub description: String, + pub category: String, + #[serde(skip_serializing_if = "Option::is_none")] + pub input_schema: Option, + #[serde(skip_serializing_if = "Option::is_none")] + pub output_schema: Option, + } + ``` + Ensure serialized JSON matches TypeScript types exactly (use serde attributes for naming). Add From for integration with aof-core Agent type (if different). Document schema in Rust doc comments. + + + Structs compile without errors.

No broken links. + + + +## Verification Steps + +### Step 1: API Configuration Endpoints +1. Start Phase 1: `cargo run -p aofctl -- serve` +2. Test agents endpoint: `curl http://localhost:8080/api/config/agents | jq` +3. Verify response is valid JSON array (even if empty []) +4. Check response headers: X-Config-Version present +5. Test tools endpoint: `curl http://localhost:8080/api/config/tools | jq` +6. Test version endpoint: `curl http://localhost:8080/api/config/version | jq` +7. Verify version is SHA256 hash (64 hex characters) + +### Step 2: Static File Serving +1. Build React: `cd web-ui && npm run build` +2. Start daemon with static dir: `cargo run -p aofctl -- serve --static-dir ./web-ui/dist` +3. Open http://localhost:8080 in browser +4. Verify index.html loads (not 404) +5. Verify page interactive (JavaScript loads) +6. Check Network tab: /assets/*.js files loaded +7. Navigate to different page (/agents): verify SPA routing (no page reload) +8. Check console: no 404 errors for assets + +### Step 3: Fallback Routing (SPA) +1. With static server running, navigate to http://localhost:8080/nonexistent-route +2. Verify page still loads (not 404) +3. Verify index.html served (React router handles route) +4. Test: http://localhost:8080/agents, http://localhost:8080/tasks, etc. +5. All should load React app (client-side routing) +6. Network tab: all requests return 200 (index.html fallback) + +### Step 4: Configuration File Loading +1. Create serve-config.yaml: + ```yaml + port: 9000 + workspace_root: . + static_dir: ./web-ui/dist + ``` +2. Run: `cargo run -p aofctl -- serve --config serve-config.yaml` +3. Verify startup message: "Listening on http://localhost:9000" +4. Verify configuration loaded and printed (debug output) +5. Test override: `cargo run -p aofctl -- serve --config serve-config.yaml --port 8080` +6. Verify flag overrides config (listens on 8080, not 9000) + +### Step 5: File Watcher (if enabled) +1. Build with feature: `cargo build --features watch` +2. Start daemon: `cargo run --features watch -- serve` +3. Edit AGENTS.md: add new agent +4. Save file +5. Check daemon logs: "Configuration reloaded" +6. Refresh browser: new agent appears in config +7. Check browser Network tab: GET /api/config/agents called +8. Verify new agent in response + +### Step 6: Error Handling +1. Create malformed AGENTS.md: + ```yaml + agents: + - name: Test Agent + skills: not-an-array # should be array + ``` +2. Test API: `curl http://localhost:8080/api/config/agents` +3. Verify 400 response with error message showing field path: "Field agents[0].skills: expected array" +4. Delete AGENTS.md file +5. Test API: `curl http://localhost:8080/api/config/agents` +6. Verify returns [] (empty array, graceful degradation) + +### Step 7: Production Build +1. In web-ui/: `npm run build` +2. Verify dist/ created with index.html, assets/ +3. Measure bundle: `du -sh dist/` (should be <2MB total) +4. Start daemon: `cargo run --release -- serve --static-dir ./web-ui/dist` +5. Open http://localhost:8080 +6. Verify page loads and functional +7. Verify performance: First Contentful Paint <2s (check DevTools) +8. Verify no console errors + +### Step 8: Combined Development Flow +1. Terminal 1: `cargo run -p aofctl -- serve` (Rust daemon on :8080) +2. Terminal 2: `cd web-ui && npm run dev` (React dev on :5173, proxied to :8080) +3. Open http://localhost:5173 +4. Edit src/App.tsx, save +5. Verify hot reload (no page refresh, WebSocket persists) +6. Check Network tab: /api/config/agents requests to :8080 (proxied) +7. Verify no CORS errors +8. Terminal 1: stop and restart daemon +9. Terminal 2: verify reconnects to WebSocket automatically + +### Step 9: Documentation Review +1. Read docs/deployment.md +2. Follow "Production" section step-by-step +3. Verify end result: single daemon serving React + APIs +4. Read .planning/docs/04-WORKSPACE-CONFIG.md +5. Verify AGENTS.md template clear and complete +6. Check .planning/PHASE-04-SUMMARY.md exists and summarizes Phase 4 + +### Step 10: Workspace Configuration End-to-End +1. Create workspace directory: ~/test-workspace/ +2. Copy AGENTS.md template: cp docs/templates/AGENTS.md.template ~/test-workspace/AGENTS.md +3. Customize agents in AGENTS.md (change names, skills) +4. Create serve-config.yaml: `workspace_root: ~/test-workspace` +5. Run daemon: `aofctl serve --config serve-config.yaml --static-dir ./web-ui/dist` +6. Open http://localhost:8080 +7. Verify agents from ~/test-workspace/AGENTS.md visible in UI +8. Edit ~/test-workspace/AGENTS.md: add new agent +9. (With watcher) Refresh browser: new agent appears +10. Verify no hardcoding: all agent data comes from AGENTS.md + +## Must-Haves + +1. **Configuration APIs functional** - /api/config/agents, /api/config/tools, /api/config/version return valid JSON, X-Config-Version header present, graceful handling of missing files. + +2. **Static file serving from Rust daemon** - React build served at / (index.html), assets served at /assets/*, SPA routing fallback (non-API routes serve index.html), single process handles both HTTP and WebSocket. + +3. **Production-ready single daemon** - No separate Node.js frontend server required. `cargo build --release && ./target/release/aofctl serve` sufficient for deployment. Static dir configurable via flag or config file. + +4. **Workspace configuration dynamic** - All agent and tool data comes from AGENTS.md and TOOLS.md in workspace. No hardcoding in code. Configuration changes reflected in UI (on refresh or with watcher). + +5. **Helpful error messages** - Invalid config returns 400 with field path (serde_path_to_error). Missing files return 404 or empty array (graceful degradation). Developer can debug issues from error messages alone. + +## Dependencies + +### What 04-01, 04-02, 04-03 Provide +- React build output (dist/ folder after `npm run build`) +- TypeScript types for Agent, Tool (used for Rust struct definitions) +- API endpoint contracts (UI expects these endpoints to exist) + +### What 04-04 Establishes +- Axum routes for configuration serving +- Static file serving infrastructure (reusable for future Rust-based frontends or assets) +- File watcher for development productivity +- Configuration schema and validation +- Deployment story (production build guide, systemd/Docker examples in future) + +### What Phase 1-3 Provides +- Axum server infrastructure (Phase 1) +- CoordinationEvent stream and WebSocket (Phase 1) +- Memory backend for persistence (Phase 2) +- Gateway and event routing (Phase 3) +- AgentExecutor and FleetCoordinator (Phase 1-2) + +## Notes + +- **Workspace Root:** Recommend workspace structure: + ``` + ~/my-aof-workspace/ + ├── AGENTS.md + ├── TOOLS.md + ├── serve-config.yaml + └── agent-scripts/ (optional) + ``` + User points aofctl to this directory with --workspace-root flag. + +- **Agent Status in API:** 04-04 returns agent metadata (id, name, role, skills).

RTK Query subscribes to events, updates Redux store, React components re-render. + +**When to use:** Real-time systems where server pushes events to client (activity feeds, agent status updates, task transitions). + +**Example:** +```tsx +// In React hook (e.g., src/hooks/useEventSubscription.ts) +import { useEffect } from 'react'; +import { useDispatch } from 'react-redux'; +import { addEvent, updateAgentStatus } from '../store/eventsSlice'; + +export function useEventSubscription(url: string = 'ws://localhost:8080/ws') { + const dispatch = useDispatch(); + + useEffect(() => { + const ws = new WebSocket(url); + + ws.onmessage = (event) => { + const coordinationEvent = JSON.parse(event.data); + + // Dispatch to Redux store + dispatch(addEvent(coordinationEvent)); + + // Handle specific event types + if (coordinationEvent.activity.type === 'AgentStarted') { + dispatch(updateAgentStatus({ + agentId: coordinationEvent.agent_id, + status: 'working', + })); + } + }; + + ws.onerror = (err) => { + console.error('WebSocket error:', err); + // Reconnect logic (exponential backoff) + }; + + return () => ws.close(); + }, [dispatch]); +} +``` + +**Integration with Redux:** +```tsx +// Store slice (src/store/eventsSlice.ts) +import { createSlice, PayloadAction } from '@reduxjs/toolkit'; + +interface CoordinationEvent { + event_id: string; + agent_id: string; + activity: { type: string; details: any }; + timestamp: string; +} + +const eventsSlice = createSlice({ + name: 'events', + initialState: { + events: [] as CoordinationEvent[], + agentStatus: {} as Record, + }, + reducers: { + addEvent: (state, action: PayloadAction) => { + state.events.push(action.payload); + // Keep last 1000 events in memory + if (state.events.length > 1000) { + state.events.shift(); + } + }, + updateAgentStatus: (state, action) => { + state.agentStatus[action.payload.agentId] = action.payload.status; + }, + }, +}); + +export const { addEvent, updateAgentStatus } = eventsSlice.actions; +export default eventsSlice.reducer; +``` + +### Pattern 2: Configuration-Driven Agent Card Rendering + +**What:** At startup, fetch AGENTS.md and TOOLS.md from API endpoint. Render agent cards dynamically with properties from config (avatar, role, skills, personality). + +**When to use:** When UI layout depends on runtime configuration, not hardcoded structure. + +**Example:** + +```tsx +// API endpoint added to aofctl serve: GET /api/config/agents +// Returns parsed AGENTS.md as structured JSON + +interface Agent { + id: string; + name: string; + role: string; + personality: string; + avatar?: string; + skills: string[]; + status: 'idle' | 'working' | 'blocked'; +} + +// In React component (src/components/AgentGrid.tsx) +import { useQuery } from 'react-query'; + +export function AgentGrid() { + const { data: agents } = useQuery('agents', async () => { + const res = await fetch('http://localhost:8080/api/config/agents'); + return res.json() as Promise; + }); + + return ( +
+ {agents?.map((agent) => ( + + ))} +
+ ); +} + +function AgentCard({ agent }: { agent: Agent }) { + return ( +
+ {agent.avatar && {agent.name}} +

{agent.name}

+

{agent.role}

+
+ {agent.skills.map((skill) => ( + {skill} + ))} +
+ +
+ ); +} +``` + +**Implementation in aofctl serve.rs:** +```rust +// Add route to serve agent config +let app = Router::new() + .route("/api/config/agents", get(get_agents_config)) + .route("/api/config/tools", get(get_tools_config)) + .route("/ws", get(handle_websocket_upgrade)) + // ... existing routes + +async fn get_agents_config() -> axum::Json> { + // Parse AGENTS.md (or load from memory backend) + // Return array of agent objects with id, name, role, skills, avatar, personality + axum::Json(vec![]) +} +``` + +### Pattern 3: Kanban Board with Optimistic Updates + +**What:** User drags task card between lanes. Local state updates immediately (optimistic). WebSocket message sent to server. If server rejects, rollback. If server confirms, merge with server state. + +**When to use:** High-latency networks or slow backend. <100ms perceived latency critical for UX. + +**Example:** + +```tsx +// Using dnd-kit for drag-and-drop +import { DndContext, closestCorners, DragEndEvent } from '@dnd-kit/core'; +import { SortableContext } from '@dnd-kit/sortable'; +import { useDispatch, useSelector } from 'react-redux'; + +export function KanbanBoard() { + const dispatch = useDispatch(); + const tasks = useSelector((state) => state.tasks.items); + const optimisticTasks = useSelector((state) => state.tasks.optimistic); + + const handleDragEnd = (event: DragEndEvent) => { + const { active, over } = event; + const taskId = active.id as string; + const newLane = over?.id as string; + + if (!newLane) return; + + // 1. Optimistic update (instant UI response) + dispatch(updateTaskLaneOptimistic({ + taskId, + newLane, + })); + + // 2. Send to server + fetch('http://localhost:8080/api/tasks/move', { + method: 'POST', + body: JSON.stringify({ taskId, newLane }), + }) + .then(() => { + // 3. Server confirmed, commit optimistic + dispatch(commitTaskLaneUpdate({ taskId, newLane })); + }) + .catch(() => { + // 4. Server rejected, rollback + dispatch(rollbackTaskLaneUpdate({ taskId })); + }); + }; + + return ( + + {['backlog', 'assigned', 'in-progress', 'review', 'done'].map((lane) => ( + + ))} + + ); +} + +function Lane({ id, tasks }: { id: string; tasks: Task[] }) { + return ( + t.id)}> +
+

{id}

+ {tasks.map((task) => ( + + ))} +
+
+ ); +} +``` + +**Redux slice for optimistic updates:** +```tsx +// src/store/tasksSlice.ts +const tasksSlice = createSlice({ + name: 'tasks', + initialState: { + items: {} as Record, + optimistic: {} as Record, // Optimistic version + pending: {} as Record>, // Track pending updates + }, + reducers: { + updateTaskLaneOptimistic: (state, action) => { + const { taskId, newLane } = action.payload; + // Move in optimistic state + const task = findTaskInState(state.optimistic, taskId); + if (task) { + removeTaskFromLane(state.optimistic, taskId); + addTaskToLane(state.optimistic, newLane, task); + } + }, + commitTaskLaneUpdate: (state, action) => { + // Optimistic was correct, no-op (or sync with server state) + }, + rollbackTaskLaneUpdate: (state, action) => { + const { taskId } = action.payload; + // Restore from items (server truth) + restoreTaskFromServerState(state); + }, + }, +}); +``` + +### Pattern 4: Real-Time Activity Feed + +**What:** Stream of agent activities rendered as timeline. New events appear at top, old events scroll away. + +**Example:** +```tsx +// src/components/ActivityFeed.tsx +import { useSelector } from 'react-redux'; + +export function ActivityFeed() { + const events = useSelector((state) => state.events.events); + + return ( +
+ {events.map((event) => ( + + ))} +
+ ); +} + +function ActivityItem({ event }: { event: CoordinationEvent }) { + const { agent_id, activity, timestamp } = event; + const timeAgo = formatDistanceToNow(new Date(timestamp), { addSuffix: true }); + + return ( +
+

+ {agent_id} {getActivityDescription(activity)} {timeAgo} +

+
+ ); +} +``` + +### Anti-Patterns to Avoid + +- **Don't poll REST API:** Real-time requires WebSocket push, not `/events?since=timestamp` polling. WebSocket is 1000x more efficient. +- **Don't block on drag-and-drop:** Update local state immediately, send server request async. Never wait for server response before showing visual feedback. +- **Don't hardcode agent list:** Load from API endpoint (GET /api/config/agents) so config changes update UI without redeployment. +- **Don't ignore WebSocket reconnection:** Network drops happen. Implement exponential backoff reconnect with event replay on recovery. +- **Don't lose task updates during network latency:** Use Redux + optimistic updates pattern. Single source of truth (server state) with local optimistic overlay. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Drag-and-drop | Custom mouse/touch handlers | dnd-kit | Handles accessibility, keyboard, mobile, nested lists, animations | +| WebSocket reconnection | Manual backoff loop | Socket.io or ws with reconnect plugin | Built-in exponential backoff, event queuing | +| Real-time state sync | Manual optimistic + rollback | Redux Toolkit + RTK Query | Handles versioning, conflict detection, cache invalidation | +| Component styling | CSS from scratch | shadcn/ui + Tailwind | Pre-built accessible components, dark mode, theming | +| Kanban sorting | Custom swap algorithm | dnd-kit + SortableContext | Handles animations, multiple drop zones, touch devices | +| Chat message ordering | Manual timestamp sort | Message IDs + server-provided ordering | Handles out-of-order arrival, deduplication | +| WebSocket JSON serialization | Manual JSON.stringify/parse | serde_json (Rust) + JSON native (JS) | Type safety, custom serializers for enums | + +**Key insight:** Real-time UI sync is harder than it looks. Optimistic updates create race conditions. WebSocket drops require replay logic. Drag-and-drop on touch has accessibility pitfalls. Use proven libraries. + +## Common Pitfalls + +### Pitfall 1: WebSocket Connection Drops, UI Freezes + +**What goes wrong:** Network hiccup causes WebSocket close. UI stops receiving events. User sees stale data, thinks app is broken. + +**Why it happens:** No reconnection logic. WebSocket is stateful—close means goodbye until app restarts. + +**How to avoid:** +- Implement exponential backoff: 1s, 2s, 4s, 8s, 30s cap +- Queue outgoing messages while disconnected +- Replay recent events on reconnect (use event IDs) +- Show "Disconnected" indicator, auto-hide on reconnect + +**Warning signs:** +- UI updates stop for 30 seconds +- Refresh page fixes it +- No error message in console + +**Example fix:** +```tsx +function useWebSocketWithReconnect(url: string) { + const [connected, setConnected] = useState(false); + const wsRef = useRef(null); + const retryCountRef = useRef(0); + + const connect = useCallback(() => { + wsRef.current = new WebSocket(url); + wsRef.current.onopen = () => { + setConnected(true); + retryCountRef.current = 0; + }; + wsRef.current.onclose = () => { + setConnected(false); + // Exponential backoff + const delay = Math.min(1000 * Math.pow(2, retryCountRef.current), 30000); + retryCountRef.current += 1; + setTimeout(connect, delay); + }; + }, [url]); + + useEffect(() => { + connect(); + return () => wsRef.current?.close(); + }, [connect]); + + return { connected, ws: wsRef.current }; +} +``` + +### Pitfall 2: Drag-and-Drop Race Condition + +**What goes wrong:** User drags task to "done" lane. Optimistic update shows it moved. Before server confirms, agent executor completes same task. Server sends task state update, overwrites optimistic move. UI flickers task back to "in-progress" then forward to "done". + +**Why it happens:** Two concurrent updates (user drag + server event) conflicting. No version numbers to detect stale data. + +**How to avoid:** +- Include version number in task: `{ id, lane, version: 5, status: 'done' }` +- Server assigns new version on each update +- On conflicting update, apply server version if newer +- Optimistic updates don't increment version (server does) + +**Warning signs:** +- Task briefly moves backward after drag +- Inconsistent UI state during drag +- Server logs show multiple versions for same task + +**Example fix:** +```tsx +// Task with version +interface Task { + id: string; + lane: string; + version: number; + status: string; +} + +// On drag end +dispatch(updateTaskOptimistic({ + taskId, + newLane, + // Don't increment version—server will +})); + +// On server event (higher version) +const existingTask = findTask(state, eventTask.id); +if (eventTask.version > existingTask.version) { + // Server is newer, apply it + dispatch(updateTaskFromServer(eventTask)); +} +``` + +### Pitfall 3: Redux State Explosion with Real-Time Events + +**What goes wrong:** Each CoordinationEvent dispatched to Redux. 100 events/sec = 6,000 actions/min. Redux devtools chokes. Chrome tab uses 500MB RAM. React re-renders every component. + +**Why it happens:** Dispatching raw events without aggregation. No cleanup of old events. + +**How to avoid:** +- Keep only last N events in store (e.g., 500) +- Use selectors to compute derived state (agent status) from events +- Don't dispatch all events—filter by agent_id on client or server +- Use `useShallowEqual` selector for large arrays + +**Warning signs:** +- Redux devtools shows 10,000+ actions +- Tab memory grows over time +- React DevTools shows all components re-rendering + +**Example fix:** +```tsx +const eventsSlice = createSlice({ + name: 'events', + initialState: { events: [] as Event[], lastEventId: '' }, + reducers: { + addEvent: (state, action) => { + state.events.push(action.payload); + state.lastEventId = action.payload.event_id; + // Keep last 500 events + if (state.events.length > 500) { + state.events = state.events.slice(-500); + } + }, + }, +}); + +// Selector with memoization +const selectAgentStatus = (state: RootState, agentId: string) => { + // Compute from events, not stored separately + return state.events.events + .filter(e => e.agent_id === agentId) + .reverse()[0]?.status || 'idle'; +}; + +// In component +const agentStatus = useSelector((state) => selectAgentStatus(state, agentId)); +``` + +### Pitfall 4: Lost Configuration on Daemon Restart + +**What goes wrong:** User loads agent grid from API (/api/config/agents). Daemon restarts. Agent AGENTS.md file changed. UI shows stale agent list. + +**Why it happens:** No cache invalidation. UI doesn't know config changed on server. + +**How to avoid:** +- Add version header to config API: `X-Config-Version: 5` +- UI caches config with version +- Periodically poll version endpoint +- On version mismatch, refetch config +- Show "Reloading configuration..." briefly + +**Warning signs:** +- Daemon restarts, agent list unchanged +- Add agent, UI still shows old list +- Page refresh fixes it + +**Example fix:** +```tsx +// In React Query +const { data: agents, refetch } = useQuery( + 'agents', + async () => { + const res = await fetch('http://localhost:8080/api/config/agents'); + return { agents: res.json(), version: res.headers.get('X-Config-Version') }; + }, + { staleTime: 5 * 60 * 1000 } // Cache for 5 minutes +); + +// Poll config version every 10 seconds +useEffect(() => { + const interval = setInterval(async () => { + const res = await fetch('http://localhost:8080/api/config/version'); + const newVersion = await res.json(); + if (newVersion.version !== agents?.version) { + refetch(); // Config changed, refetch + } + }, 10000); + return () => clearInterval(interval); +}, [agents?.version, refetch]); +``` + +### Pitfall 5: Leptos WASM Bundle Bloat + +**What goes wrong (if taking Leptos path):** Leptos app with all features compiles to 850KB WASM. Gzipped 280KB. Initial load takes 5 seconds on 4G. + +**Why it happens:** Leptos includes reactive runtime, DOM binding, serde, all dependencies bundled. + +**How to avoid:** +- Use `wasm-opt -Oz` for aggressive size reduction (15-20% savings) +- Use cargo-features to exclude unused deps (no serde_yaml if not needed) +- Use islands architecture (only interactive parts as WASM, static HTML otherwise) +- Set `opt-level = "z"` in Cargo.toml release profile + +**Warning signs:** +- `wasm-pack build` outputs >500KB uncompressed +- Initial load >3 seconds +- Gzipped > 150KB + +**Example fix:** +```toml +# Cargo.toml +[profile.release] +opt-level = "z" # Optimize for size +lto = true # Link-time optimization +codegen-units = 1 # Single codegen unit for better optimization +panic = "abort" # Reduces panic handling code +strip = true # Strip symbols +``` + +```bash +# Build with wasm-opt +wasm-pack build --release --target web +wasm-opt -Oz -o pkg/app_bg.wasm pkg/app_bg.wasm +``` + +### Pitfall 6: Keyboard Navigation in Drag-and-Drop Lost + +**What goes wrong:** Using dnd-kit but didn't enable keyboard support. Only mouse/touch works. Screen reader users can't reorder tasks. + +**Why it happens:** dnd-kit defaults to mouse/touch. Keyboard + accessibility require explicit setup. + +**How to avoid:** +- Use dnd-kit's `useDraggable` with `attributes.roleDescription` for screen readers +- Add keyboard handlers for arrow keys (move between items) +- Test with keyboard + screen reader (NVDA, VoiceOver) +- Use ARIA labels for lanes and tasks + +**Warning signs:** +- Tab key doesn't focus drag handles +- Can't hear what task is under cursor (screen reader) +- No visual focus indicator on keyboard nav + +**Example fix:** +```tsx +// Use dnd-kit keyboard support +import { KeyboardCode, KeyboardSensor } from '@dnd-kit/core'; + + + {/* content */} + + +// In task card +
