Writers queue on the single-writer lock (proven under 14-process +load); the brief's *active in the last hour* section is the cross-agent +awareness surface, and *current understanding* interleaves every agent's +observations. Session exhaust from N agents becomes one mind. + +## Output contract + +**stdout is an API.** The SessionStart hook injects `brief` stdout verbatim +into an agent's context, and `--json` is machine-read. Therefore: + +- spinners and phase timings live on stderr, only when stderr is a terminal; +- color reaches stdout only when stdout is a terminal, via one style + vocabulary (bold headers, cyan identities, dim metadata, red distrust + signals) applied identically by the template filters and every verb; +- piped, hooked, and `--json` output is byte-for-byte unstyled — no flags + needed, `NO_COLOR` and `TERM=dumb` also respected. + +## Customizing the brief + +`brief.tmpl` (embedded default) is the experimentation surface: a minijinja +template over `BriefJson` with zero logic beyond section presence. Drop an +override at `.peat/brief.tmpl` and re-run `brief` — no rebuild. Style filters +available in templates: `h1`, `dim`, `warn`, `accent`, `clip(n)` (identity +when stdout is not a terminal). + +## Testing + +Two oracles are non-negotiable and written to be **red-capable** — each has a +proof it can fail: + +1. **Retraction is observable**: upserting a revision over an event id makes + the replaced text unfindable in both the keyword and vector indexes. An + `#[ignore]`d twin asserts the opposite; `cargo test -p peat -- --ignored` + must FAIL, proving the live oracle is not vacuous. +2. **Replay determinism**: folding any prefix of the ledger equals an + independent scan's prediction, at multiple cut points, and transaction + batching is unobservable. + +Plus: idempotent double-capture, a golden test against a real (sanitized) +transcript in `tests/fixtures/`, never-fatal parsing of unknown line types, +and ISO-8601 round-tripping. + +## Deferred by decision, not oversight + +Belief support/flips semantics, `Merge{from,to}` subject-drift repair, +session fingerprints, a `why` verb over the evidence trail, multi-writer +spools. All are replay-backfillable later precisely because capture is total. +The subjects view stays deliberately dumb (newest-wins): anything cleverer +must be expressible as a fold over events still visible in the raw ledger. + +## Performance + +Measured on a ~44k-event ledger (28 sessions, including 100 MB+ transcripts): +`brief` 0.13 s · semantic query 0.18 s · full `asof` replay of 14k events +1.2 s.

Use when the user explicitly asks to check the graph or research, or when competing designs depend on a general principle not settled by local source, measurements, or project specifications. Do not invoke for routine local debugging, performance diagnosis, gate maintenance, naming, mechanical refactors, or merely because a task uses the word design. For current papers beyond the graph, use the papers skill.\n- review: Quick post-change code review for the current session. Use when finishing implementation work and wanting a sanity check before committing. Catches correctness issues, code smells, DRY violations, security gaps, missing tests, dead code, naming problems, and concurrency bugs. Runs project linters automatically.

Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.\n- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: \"chart\", \"graph\", \"plot\", \"data viz\", \"visualization\", \"dashboard\", \"analytics\", \"visualize data\", \"categorical colors\", \"sequential / diverging palette\", \"stat tile\", \"sparkline\", \"heatmap\", \"legend\", \"axis\", \"tooltip\", \"chart colors\", \"color by series\".\n- artifact-design: Design guidance and fundamentals for Artifacts.\n- artifact-diagramming: Diagramming know-how for Artifacts — when a picture earns its place, how to draw one that shows the real mechanism, and the inline-SVG mechanics that keep it legible in both themes.\n- artifact-capabilities: Runtime capabilities a published Artifact page can be granted — behavior static HTML cannot provide on its own, such as the page reading live or connected data, keeping state shared across viewers, or updating and republishing itself. Serves this user's live capability roster and the typed call definitions. Load it whenever the user asks for an artifact needing any such runtime behavior.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- code-review: Review the current diff, or a PR number/branch/path target, for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud); with no level given, it reuses the level you typed last. Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- claude-in-chrome: Automates your Chrome browser to interact with web pages - clicking elements, filling forms, capturing screenshots, reading console logs, and navigating sites. Opens pages in new tabs within your existing Chrome session. Requires site-level permissions before executing (configured in the extension). - When the user wants to interact with web pages, automate browser tasks, capture screenshots, read console logs, or perform any browser-based actions. Always invoke BEFORE attempting to use any mcp__claude-in-chrome__* tools.\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init\n-
