The context hook was not appearing in Claude Code sessions because it was
outputting plain text to stdout instead of using the required JSON structure
for SessionStart hooks.
Changes:
- src/hooks/context.ts: Changed contextHook to return string instead of void,
removing direct console.log calls to make it more reusable
- src/bin/hooks/context-hook.ts: Wrap contextHook output in hookSpecificOutput
JSON structure with hookEventName "SessionStart" and additionalContext field
- Both TTY and stdin code paths now properly format and exit with code 0
Fixes the issue where recent session context was not being injected at session
start. Tested with npm run test:context - hook now properly outputs JSON with
recent sessions formatted as markdown.

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.
