Hooks System

Hook Types

• PreToolUse: Before tool execution (validation, parameter modification)
• PostToolUse: After tool execution (auto-format, checks)
• Stop: When session ends (final verification)

Auto-Accept Permissions

Use with caution:

• Enable for trusted, well-defined plans
• Disable for exploratory work
• Never use dangerously-skip-permissions flag
• Configure allowedTools in ~/.claude.json instead

TodoWrite Best Practices

Use TodoWrite tool to:

• Track progress on multi-step tasks
• Verify understanding of instructions
• Enable real-time steering
• Show granular implementation steps

Todo list reveals:

• Out of order steps
• Missing items
• Extra unnecessary items
• Wrong granularity
• Misinterpreted requirements
