Implements automatic memory extraction when Claude Code sessions end:

  • Add SessionEnd hook to hooks.json with 120s timeout
  • Create session-end.sh wrapper that parses hook input and runs summarizer
  • Create summarize-transcript.py that:
    • Loads transcript from Claude's storage
    • Skips trivial sessions (<3 user messages)
    • Extracts paths/facts via heuristics
    • Uses Claude CLI (subscription auth) for decisions/preferences
    • Saves to memory files with deduplication
    • Updates history index with summarized flag

Uses claude -p --model haiku for LLM extraction, leveraging
existing subscription credentials instead of requiring API key.
