Recall

Query the session activity index for event history, file change logs, decisions, and errors. The session index is written continuously by the PostToolUse hook and persists across compaction events.

Skill type: Rigid -- follow exactly, no shortcuts.

Execution model: Direct execution by the orchestrator. No subagent dispatch. No Agent/Task tool needed.

Announce at start: Output [recall] Querying session activity index... before any processing.

Session Index Discovery

The session index lives at:

~/.claude/projects/<project-hash>/memory/session-index/<session-id>/
  events.jsonl      # append-only event log
  summary.md        # rolling narrative summary
