Rebuild rules index at SessionStart when stale#14
Merged
Conversation
The rules index (.claude/rules/decisions.md) only updated via PostToolUse when Claude Code's Write tool wrote decision files. Files created outside Claude Code (manual edits, git pull, other tools) left the index stale. Now session_init checks if any decision file is newer than the index and regenerates it before the session begins. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
