- Implemented a new tool to search for observations using natural language and retrieve timeline context around the best match.
- Introduced two modes: "auto" for automatic timeline anchor selection and "interactive" for user selection of top matches.
- Added input schema validation using zod for query parameters including depth before/after, limit, and project filtering.
- Integrated hybrid semantic search with fallback to FTS5 for observation retrieval.
- Enhanced response formatting for both modes, including detailed timeline context and observation summaries.
- Added `getObservationById` method to retrieve observations by ID in SessionStore.
- Introduced `getSessionSummariesByIds` and `getUserPromptsByIds` methods for fetching session summaries and user prompts by IDs.
- Developed `getTimelineAroundTimestamp` and `getTimelineAroundObservation` methods to provide a unified timeline of observations, sessions, and prompts around a specified anchor point.
- Enhanced ChromaSync to format and sync user prompts, including a new `syncUserPrompt` method.
- Updated WorkerService to sync the latest user prompt to Chroma after updating the worker port.
- Created tests for timeline querying and MCP handler logic to ensure functionality.
- Documented the implementation plan for user prompts and timeline context tool in the Chroma search completion plan.
Changes:
- Updated legend to show only observation types (bugfix, feature, refactor, change, discovery, decision)
- Mapped each type to a color dot emoji (🔴 bugfix, 🟢 feature, 🔵 refactor, ⚪ change, 🟡 discovery, 🟤 decision)
- Removed concept-based filtering and icon selection
- Simplified progressive disclosure instructions to reference types instead of concepts
- All observations now shown in timeline (no concept filtering)
Technical details:
- Modified: src/hooks/context-hook.ts:203-207 (legend)
- Modified: src/hooks/context-hook.ts:210-223 (progressive disclosure text)
- Modified: src/hooks/context-hook.ts:344-369 (icon mapping switched from concepts to types)
- Modified: src/hooks/context-hook.ts:168-173 (removed concept filtering)
- Rebuilt: plugin/scripts/context-hook.js
Rationale: Types are mutually exclusive and core to categorization, while concepts are multi-select metadata better accessed through MCP search tools. This simplifies the display and reduces visual noise.

This hook displays context information to users via stderr, which is
currently the only way to show messages in Claude Code UI. It runs in
parallel with context-hook during SessionStart.

Problem: npm install outputs "up to date in Xms" to stdout, which prepends
non-JSON text to the hook output. Claude Code expects pure JSON and cannot
parse the output, causing context injection to fail silently.
Solution: Changed npm install flag from --loglevel=error to --loglevel=silent
to completely suppress stdout output, ensuring clean JSON output for hook.
Impact: SessionStart hook will now properly inject recent context into sessions.

- Removed bin/hooks/ wrapper layer
- Moved all hook logic into consolidated hooks/*-hook.ts files
- Each hook now handles its own stdin/stdout/JSON wrapping
- Removed ALL try-catch blocks from context-hook (let errors surface)
- Updated build script to reference new src/hooks/ paths
- Reduced from 12+ files to 6 hook files
This simplifies the architecture and makes debugging actually possible.
- Wrap stdin event handler in try/catch to catch async errors
- Output errors to stdout so Claude can see them
- Show input preview and stack trace for debugging
- Remove outer try/catch that wasn't catching async errors
- Implemented `findClaudePath` function to determine the path of the Claude executable using environment variables or system commands (`which` for Unix/Mac and `where` for Windows).
- Integrated the `findClaudePath` function into the SDK worker and worker service to ensure the correct executable path is used when running the SDK agent.
- Enhanced error handling and logging for better debugging and user feedback regarding the executable path.
- Updated logic to retrieve recent summaries and observations, focusing on the last 4 summaries for better context.
- Simplified the extraction of unique session IDs from the recent summaries.
- Enhanced the timeline rendering to include both observations and summaries, grouped by day and file.
- Removed redundant queries for recent summaries and observations, streamlining the data retrieval process.
- Improved output formatting for better readability, including color-coded sections and clearer headers.
- Added detailed display of the most recent session's completed status and next steps.
- Introduced new helper functions for parsing JSON, formatting dates, and estimating token counts.
- Implemented retrieval of recent session IDs and observations from the database.
- Added filtering of observations based on key concepts for a more relevant timeline.
- Enhanced output formatting to include a chronological timeline of recent activities grouped by day and file.
- Included a legend for better understanding of the timeline icons.
- Displayed recent session summaries with improved formatting and details.
- Added footer instructions for accessing records via MCP search.
Critical bugfix release.
Problem:
- NOT NULL constraint violations prevented all observations/summaries from being stored
- Worker service could not store any data in database
- System was completely non-functional for new sessions
Root Cause:
- SessionStore.getSessionById() missing claude_session_id in SELECT query
- Worker received undefined for claude_session_id
- Caused database INSERT failures
Fix:
- Added claude_session_id to getSessionById SQL query
- Updated return type to include claude_session_id field
- Session ID now flows correctly: hook → database → worker → SDK
Impact:
- All observation and summary storage now works correctly
- System maintains session consistency throughout lifecycle
- Critical for proper functioning of memory compression
Version Changes:
- package.json: 4.2.7 → 4.2.8
- marketplace.json: 4.2.6 → 4.2.8
- CLAUDE.md: Updated version and added v4.2.8 changelog
Files Changed:
- package.json (version bump)
- .claude-plugin/marketplace.json (version bump)
- CLAUDE.md (version and changelog)
- src/services/sqlite/SessionStore.ts (bugfix)
- plugin/scripts/* (rebuilt with fix)

Critical bugfix for NOT NULL constraint violation.
Problem:
- Worker service calls getSessionById(sessionDbId) to fetch session data
- Worker then uses dbSession.claude_session_id to create ActiveSession
- But getSessionById was NOT selecting claude_session_id from database
- Result: claudeSessionId = undefined in worker
- Caused: "NOT NULL constraint failed: sdk_sessions.claude_session_id" errors
- Impact: Observations and summaries couldn't be stored
Root cause:
- SessionStore.getSessionById() SQL query missing claude_session_id column
- Line 710-713: "SELECT id, sdk_session_id, project, user_prompt"
- Should be: "SELECT id, claude_session_id, sdk_session_id, project, user_prompt"
Fix:
- Added claude_session_id to SELECT query in getSessionById
- Updated return type to include claude_session_id: string
- Now worker correctly receives claude_session_id from database
- Session ID from hook flows properly through entire system
Files changed:
- src/services/sqlite/SessionStore.ts (getSessionById method)
Testing:
- Build succeeded
- Ready for PM2 restart and live testing

Critical Bugfix:
- Fixed overly defensive observation validation blocking observations from being saved
- Parser now NEVER skips observations - always saves them
- Invalid or missing type defaults to "change" (generic catch-all type)
- Removed validation requiring title, subtitle, and narrative fields
- Prevents critical data loss - partial observations better than no observations
Impact:
- Before: Missing title, subtitle, OR narrative caused entire observation to be discarded
- After: ALL observations preserved regardless of field completeness
- Even partial observations contain valuable data: concepts, files_read, files_modified, facts
- LLMs make mistakes - system must be resilient and save everything
- Consistent with v4.2.5 summary fix
Technical changes:
- Updated src/sdk/parser.ts:52-67 to never skip observations
- Uses "change" as fallback type for invalid/missing types (no schema change)
- Updated ParsedObservation interface to allow null for title, subtitle, narrative
- Updated SessionStore.storeObservation signature to accept nullable fields
- Updated built worker-service.cjs
- Bumped version to 4.2.6 in all metadata files
