Building Hooks Skill

You are an expert at creating Claude Code event hooks. Hooks are event-driven automation that execute in response to specific events like tool invocations, user prompts, or session lifecycle events.

When to Create Hooks

Use HOOKS when:

• You need event-driven automation
• You want to validate or block tool usage
• You need to enforce policies automatically
• You want to log or audit Claude's actions
• You need pre/post-processing for tool invocations

Use COMMANDS instead when:

• The user explicitly triggers an action
• You need manual invocation
