- Introduced a new Logger utility to standardize logging with correlation IDs and structured context.
- Replaced console.error and console.log statements with logger methods in various modules including save.ts, summary.ts, parser.ts, HooksDatabase.ts, and worker-service.ts.
- Enhanced error handling and logging for better traceability of observations and summaries.
- Made observations.text nullable in the database schema to support structured fields.
- Added correlation IDs for tracking observations through the processing pipeline.
All 4 hook entry point scripts were missing process.exit(0) after successful
execution, causing Node processes to hang indefinitely instead of returning
control to Claude Code with exit code 0.
Root cause: In commit 6f62a56, process.exit(0) calls were removed from the
hook functions but were never added to the entry point scripts that wrap them.
Fixed files:
- src/bin/hooks/save-hook.ts (PostToolUse)
- src/bin/hooks/new-hook.ts (UserPromptSubmit)
- src/bin/hooks/summary-hook.ts (Stop)
- src/bin/hooks/context-hook.ts (SessionStart)
This restores proper hook exit behavior and prevents Claude Code from waiting
indefinitely for hook completion.
- Updated observation schema to include hierarchical fields: title, subtitle, facts, narrative, concepts, files_read, and files_modified.
- Modified the save-hook and summary-hook scripts to accommodate the new observation structure.
- Added migration logic to the HooksDatabase for adding new fields to the observations table.
- Refactored the parser to extract new fields from XML formatted observations.
- Adjusted prompt generation to reflect the new observation format and requirements.
- Updated worker service to handle new observation and summary structures.
- Introduced `getSessionById` method in HooksDatabase to retrieve session details by ID.
- Updated context, new, save, and summary hooks to utilize the new `getSessionById` method.
- Enhanced session management by adding `worker_port` and `prompt_counter` columns to relevant tables.
- Improved logging in WorkerService to provide clearer output during session initialization and processing.
- Removed redundant error logging in favor of more informative console logs.
- Updated save-hook.js and summary-hook.js to include new database columns for tracking worker ports and prompt numbers.
- Implemented migration logic to remove UNIQUE constraints from session_summaries table and added necessary indices.
- Modified HooksDatabase methods to return boolean values indicating success or failure of updates.
- Changed logging from error to info level in WorkerService for better clarity on session management and initialization.
- Added prompt_number to observations and session summaries for better tracking.
- Implemented prompt counter in SDK sessions to manage user prompts effectively.
- Updated database schema to include prompt tracking columns and removed unique constraints on session summaries.
- Modified hooks to utilize prompt_number in observations and summaries.
- Changed worker service to handle summarize requests instead of finalize, keeping the SDK agent active.
- Improved logging for better debugging and tracking of prompt numbers across sessions.
- Added WorkerService to handle long-running HTTP service with session management.
- Implemented endpoints for initializing, observing, finalizing, checking status, and deleting sessions.
- Integrated with Claude SDK for processing observations and generating responses.
- Added port allocator utility to dynamically find available ports for the service.
- Configured TypeScript settings for the project.
