Guide the user to create a hook in .github/hooks/.

Extract from Conversation

First, review the conversation history. If the user has been expressing concerns about agent behavior (e.g., "don't run this command", "always check before doing X", "inject this context"), generalize that into a hook. Extract:

• Actions that should be blocked or gated
• Context that should be injected at certain points
• Automation needs at session start/end or tool use

Clarify if Needed

If no clear policy need emerges from the conversation, clarify:

• What event should trigger this hook? (e.g. PreToolUse, SessionStart, Stop)
• Should it block, warn, or inject context?
• Does it need a companion script?

Iterate

1. Draft the hook JSON (and any scripts) and save them.
2. Identify the most ambiguous or weak parts and ask about those.
3. Once finalized, summarize what the hook enforces, suggest ways to test it, and propose related customizations to create next.

Remember to follow the agent-customization guidelines to create highly effective hooks.
