Can I block Claude from performing certain actions?

Yes, by setting the action field to 'block' in the rule's frontmatter, you can prevent operations that match your defined patterns or stop the session entirely.

What events can trigger a Hookify rule?

Rules can trigger on bash commands, file edits (Edit/Write/MultiEdit), stop events (completion checks), or user prompt content.

What is a Hookify rule?

A Hookify rule is a markdown file with YAML frontmatter that defines specific patterns to watch for in Claude's environment, triggering custom messages or operation blocks when matched.

Where are Hookify rules stored?

Rules are stored in the project root under the .claude/ directory with the naming convention hookify.{rule-name}.local.md.

개발자 도구

Simplifies the creation of custom guardrails and automation triggers for Claude Code using Hookify's markdown-based rule system.

This skill provides comprehensive guidance on crafting Hookify rules to enhance Claude's behavior during development tasks. It helps users define patterns to monitor bash commands, file modifications, and session completions, allowing for automated warnings or blockages when dangerous or non-compliant actions are detected. By leveraging regex-based conditions and YAML frontmatter, developers can enforce best practices, prevent security leaks like hardcoded API keys, and maintain project-specific standards directly within their Claude Code environment.
