Can I prevent Claude from running specific commands?

Yes, by setting the action to 'block' and the event to 'bash' in the rule's frontmatter, you can prevent Claude from executing unauthorized or dangerous commands.

Do changes to Hookify rules require a restart?

No, rules are read dynamically on the next tool use, meaning changes take effect immediately after saving the markdown file.

Where should I store Hookify rules?

Rules should be stored in the .claude/ directory of your project root, following the naming convention .claude/hookify.{name}.local.md.

How do I test my Hookify regex patterns?

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

What are Hookify rules in Claude Code?
