Summary

• Add compact interaction and journey results with correlated evidence, state summaries, and diagnostics.
• Update tool definitions, agent skills, documentation, and changelog for the new result format.
• Add unit and device smoke coverage for compact results and evidence correlation.

Testing

• Added unit tests and automated device smoke tests for compact interaction results, correlated evidence, and system traces.
• Validation commands not reported.

Summary by CodeRabbit

• New Features
  • Added compact interaction and journey responses that retain key outcomes, verification status, readiness blockers, and observed-state information within defined size limits.
  • Added diagnostics lookup for retrieving retained detailed results without replaying an interaction. Retention is temporary and subject to size and capacity limits.
  • Debug output remains available, and default response modes are unchanged.
• Documentation
  • Added guidance on compact responses, diagnostics access, retention limits, and privacy considerations, including that compact output does not redact private UI text.

Walkthrough

The server now returns bounded compact interaction and journey results with selected outcome, verification, readiness, state, and evidence fields. It retains original results for session-scoped diagnostics lookup. Journey evidence handling, tests, and documentation were also updated.

Verification adds matching post-dispatch observations. Tests cover evidence freshness, error handling, and trace IDs.

The projection classifies observed state, applies truncation, and retains selected fields. Tests and documentation cover response limits and state semantics.
Retain and retrieve original results src/server/handlers/interaction-diagnostics.ts, src/server/schemas/interaction-diagnostics.ts, src/server/handlers/tool-handlers.ts, src/server/tool-definitions.ts, test/fixtures/contracts/tool-definitions.json, test/unit/server/interaction-diagnostics.test.ts, test/unit/server/conditional_actions.test.ts, test/unit/server/correlated-evidence.test.ts, test/device/automated/observe/correlated-evidence.smoke.ts, test/unit/debugger/handle-guards.test.ts, test/unit/server/selector_tap_target.test.ts, docs/tools/*, agent-plugin/*/skills/mobile-debug-mcp/SKILL.md	The diagnostics tool validates lookup IDs and retrieves retained results subject to expiry and cache limits. Tool descriptions, tests, and guides document diagnostics references and retained evidence.

Minor · Functional Correctness · Quick win

Qualify the blocking-tree guidance by response mode.

When a caller uses compact mode, condition does not include the exact fresh tree claimed here. The caller must use get_interaction_diagnostics to inspect it. State that the tree is present directly only in debug mode. As per coding guidelines, “Keep tool documentation, README, and changelog aligned when usage or behaviour changes.”

- Around line 325-332: Update withJourneyStepEvidence to assemble evidence from
observations added during the operation when it throws, attach that evidence to
the Error, and rethrow it; update executeStep to include attached evidence in
its failure result. Preserve the existing success path and returned timeout
payload behavior.

Review comments at @src/server/handlers/compact-interaction.ts:
- Line 73: Update the journey error handling that uses boundedValue to compare
the bounded message with the original message and set truncated: true when they
differ, even if enforceBudget does not mark the result truncated. Keep the
existing error fields and budget behavior unchanged, consistent with
addCompactError.

71-72: Trivial · Functional Correctness · Low value

Test truncation inside a multibyte character.

The emoji case ends on a 128-byte character boundary. Add a case that crosses the boundary and assert the retained text. The byte-length assertion alone would not detect a lone surrogate.

Suggested test change

-for (const message of ['short error', 'a'.repeat(128), 'a'.repeat(129), '😀'.repeat(33)]) {
+for (const message of ['short error', 'a'.repeat(128), 'a'.repeat(129), '😀'.repeat(33), 'a' + '😀'.repeat(32)]) {
   const response = finalizeCompactInteraction('run_journey', {}, wrapResponse({ error: { code: 'FIXTURE_ERROR', message } }))
   const result = decode(response)
   const shortened = Buffer.byteLength(message) > 128
   assert.equal(result.truncated, shortened ? true : undefined)
   assert.equal(result.error.code, 'FIXTURE_ERROR')
   assert.ok(Buffer.byteLength(result.error.message) <= 128)
