Can I prevent Claude from running specific commands?

Yes, by setting the action to 'block' in the YAML frontmatter, you can prevent the operation from proceeding when a pattern matches.

What is a Hookify rule?

A Hookify rule is a project-specific markdown file that tells Claude Code to watch for certain patterns and respond with specific guidance or blocks.

Which events can Hookify rules trigger on?

Rules can trigger on bash commands (bash), file edits (file), when the agent wants to finish (stop), or when a user submits a prompt (prompt).

Where should I save my custom rules?

Rules should be saved in the .claude/ directory of your project root with the naming convention .claude/hookify.{rule-name}.local.md.
