Where should Hookify rule files be stored?

Rules should be stored in the .claude/ directory within your project root, using the naming convention .claude/hookify.{rule-name}.local.md.

What event types can trigger a Hookify rule?

Rules can trigger on 'bash' (command line tools), 'file' (editing or writing files), 'stop' (when the agent attempts to finish), 'prompt' (user input), or 'all' events.

How do I test my Hookify regex patterns?

You can test patterns using Python's re module in the terminal or use online tools like regex101.com using the Python flavor.

Can I prevent Claude from running specific commands?

Yes, by setting the 'action' field to 'block' in the rule's YAML frontmatter, you can prevent specific bash operations or file edits from proceeding.

What are Hookify rules in Claude Code?

Hookify rules are project-specific markdown files that define regex patterns for Claude to monitor, triggering custom messages or blocking actions when those patterns are matched during a session.
