What is a Hookify rule in Claude Code?

A Hookify rule is a specialized markdown file with YAML frontmatter that defines patterns for Claude to watch for, allowing it to provide warnings or block actions when those patterns are matched.

Where should Hookify rules be stored?

Hookify rules should be stored in your project's root within the .claude/ directory, following the naming convention hookify.{rule-name}.local.md.

Can I block specific terminal commands using this skill?

Yes, by setting the event type to 'bash' and defining a regex pattern, you can configure Hookify to warn the agent or block dangerous commands entirely.

Do I need to restart my session to apply rule changes?

No, Hookify rules are read dynamically by Claude. Changes to your .local.md files take effect immediately on the next tool use.

What types of events can Hookify trigger on?

Hookify supports multiple event types: 'bash' for terminal commands, 'file' for edit/write operations, 'stop' for agent completion, and 'prompt' for user inputs.
