Hooks

Hooks integrate poc-memory into Claude Code's session lifecycle. Two hook binaries fire on session events, providing memory recall and notification delivery.

Setup

Configured in ~/.claude/settings.json:

{
  "hooks": {
    "UserPromptSubmit": [{"hooks": [
      {"type": "command", "command": "memory-search", "timeout": 10},
      {"type": "command", "command": "poc-hook", "timeout": 5}
    ]}],
    "PostToolUse": [{"hooks": [
      {"type": "command", "command": "poc-hook", "timeout": 5}
    ]}],
    "Stop": [{"hooks": [
      {"type": "command", "command": "poc-hook", "timeout": 5}
    ]}]
  }
}

memory-search (UserPromptSubmit)

Fires on every user prompt. Two modes:

1. First prompt or post-compaction: loads full memory context via poc-memory load-context — journal entries, identity nodes, orientation file, configured context groups.

2. Every prompt: keyword search over the knowledge graph, returns relevant memories as additionalContext. Deduplicates across the session to avoid repeating the same memories.

poc-hook (UserPromptSubmit, PostToolUse, Stop)

Signals session activity to poc-daemon and delivers pending notifications:

• UserPromptSubmit: signals user activity, drains pending notifications into additionalContext
• PostToolUse: signals assistant activity (tool use implies the session is active)
• Stop: signals session end, triggers experience-mine
