Can Hookify rules prevent me from running dangerous commands?

Yes, by setting the event to 'bash' and the pattern to match dangerous syntax, you can configure the rule to warn you or even block the operation entirely before it executes.

What regex engine does the rule-identifier skill use?

The patterns in Hookify rules use Python regex syntax, which allows for powerful literal and metacharacter matching across file paths, commands, and text content.

What is a Hookify rule in Claude Code?

A Hookify rule is a specialized markdown file stored in your project that allows Claude Code to monitor actions—like running commands or editing files—and provide warnings or block operations based on specific patterns you define.

Where should I store my Hookify rules?

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

What happens if I change a rule during a session?

Hookify rules are read dynamically. Any changes you make to the .local.md files take effect immediately upon the next tool use or event trigger without needing to restart the session.

Security & Testing

Simplifies the creation and management of custom Hookify rules to automate code reviews, enforce standards, and prevent dangerous commands in Claude Code.

About

This skill provides specialized guidance for authoring Hookify rules, which are markdown-based configuration files that monitor and influence Claude's behavior during a session. By defining patterns across bash commands, file edits, and session events, users can implement automated safety guardrails, project-specific coding standards, and mandatory completion checklists. It streamlines the process of writing regex-based conditions and frontmatter metadata, ensuring that Claude adheres to best practices while preventing common errors like committing sensitive information or executing destructive shell operations.
