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.
- 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.
- Introduced a new `hook-response.ts` module to create standardized hook responses.
- Updated `context-hook.ts`, `new.ts`, `save.ts`, and `summary.ts` to utilize the new response format.
- Enhanced error handling in `context-hook.ts` to check for input from stdin.
- Refactored database interaction in hooks to ensure consistent session management.
- Improved readability and maintainability of hook implementations by restructuring code.
- Updated database queries to use consistent variable naming and formatting.
- Modified the handling of socket connections in `save.ts` and `summary.ts` to ensure proper response on close and error events.
- Implemented context-hook.ts for handling session start events.
- Created new-hook.ts for user prompt submission events.
- Developed save-hook.ts for post tool use events.
- Added summary-hook.ts for handling stop events.
- Introduced worker.ts as a standalone background process for the SDK agent.
- Each hook reads input from stdin, processes it, and handles errors gracefully.
