Summary

  • Show recalled lessons in Pi's memory_search tool and automatic context.
  • Show the empty-results message only when neither memories nor lessons are returned.
  • Add a regression test for a lesson-only response.

Fixes #1582

Verification

  • Targeted Pi regression test: 1 passed.
  • skills:gen, docs:sync, and skills:check completed; docs:sync made no changes.
  • Full local Windows suite: 3,683 passed, 80 failed across unrelated platform and local HTTP fixtures; the new test passed.
  • Local build stopped in Rolldown with an onLog binding error.

Summary by CodeRabbit

  • New Features
    • Memory searches now include relevant lessons alongside matching memories, clearly labeled as reference information.
    • Relevant lessons are included in the assistant’s recall context when available, even if no matching memories are found.
    • Retrieve a lesson’s full content by ID through the Pi integration or REST API.
  • Documentation
    • Updated integration and API references to include lesson retrieval and current endpoint and function counts.

📝 Walkthrough

The REST API adds authenticated lesson retrieval. The Pi integration includes lessons from smart-search responses in manual search results and startup recall, and adds a tool to fetch a lesson by ID. Tests and documentation cover these changes.

Changes: Lesson retrieval and Pi lesson recall

Layer / File(s) Summary
Lesson retrieval endpoint
src/triggers/api.ts, test/api-lessons-audit.test.ts, plugin/skills/agentmemory-rest-api/REFERENCE.md
The new POST /agentmemory/lessons/get endpoint validates the lesson ID and optional project, then returns the matching lesson or an error. Tests cover successful retrieval and not-found cases. The API reference lists the endpoint.
Pi lesson search and recall
integrations/pi/index.ts, integrations/pi/README.md, integrations/pi/package.json, test/pi-lessons.test.ts, README.md
Pi search and startup recall now include formatted lessons when present. The new memory_get_lesson tool retrieves lesson content by ID. Tests cover search output, retrieval, and automatic recall.
Endpoint and function inventory updates
src/index.ts, scripts/docs-sync.state.json, AGENTS.md, README.md, READMEs/*, plugin/skills/agentmemory-rest-api/REFERENCE.md
The endpoint count changes from 143 to 144, and the function count changes from 324 to 325 in the documented and recorded totals.

Merge Risk: 🔵 Low · up to 7a5bd

Pi can tell users a lesson is missing when retrieval actually failed, and the Polish README has a grammar error. Both are bounded issues that can be corrected without blocking the core lesson-recall workflow.

Full details: Linked Issues check

Explanation

Issue [#1582] requires Pi to parse lessons from /agentmemory/smart-search and render them in both memory_search and before_agent_start. integrations/pi/index.ts adds SmartSearchResponse.lessons, renders a ## Lessons Learned block, and includes lessons in both paths. The memory_search fallback runs only when both results and lessons are empty. test/pi-lessons.test.ts covers lesson-only manual search and automatic recall.

Full details: Out of Scope Changes check

Explanation

The PR also adds a memory_get_lesson Pi tool, a new authenticated api::lesson-get endpoint, endpoint tests, and documentation and inventory updates. Issue [#1582] requires rendering lessons returned by smart search. It does not require fetching lesson content by ID or adding an API endpoint. These changes implement the extra commit intent rather than the linked issue.

Resolution

Remove the new lesson-fetch endpoint, Pi tool, related endpoint test, and generated documentation and inventory changes from this PR. Submit that functionality under a separate issue, or link an issue that explicitly requires full lesson retrieval by ID.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 7 functions across 5 files. (38 skipped: 38 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

🟥 Missing project exposes other projects' lessons

When a caller omits project, api::lesson-get returns any matching lesson, regardless of its project. A caller with the shared bearer credential can read another project's lesson by ID.

Do not report every retrieval failure as a missing lesson.

If the request fails or returns a non-OK response, callAgentMemory returns null. The tool then says “Lesson not found.” even when the server is unavailable or authorization fails. Use a fallback that does not claim the lesson is missing when the cause is unknown.

Correct the noun after 325.

Change 325 funkcje to 325 funkcji. The new count makes the existing noun form incorrect in Polish.
