What events can trigger a Hookify rule?

Rules can trigger on bash commands (bash), file modifications (file), when the agent finishes a task (stop), or when a user submits a prompt (prompt).

Where should I store my Hookify rules?

Rules should be saved in your project root under the path .claude/hookify.{rule-name}.local.md and are typically added to your .gitignore.

How do I temporarily disable a Hookify rule?

You can temporarily disable a rule by setting 'enabled: false' in the rule's YAML frontmatter without having to delete the file.

Can I use multiple conditions in a single rule?

Yes, Hookify supports advanced formatting where multiple conditions—such as checking both a file path and the specific text being added—must match for the rule to trigger.

What is a Hookify rule?

A Hookify rule is a markdown file with YAML frontmatter stored in the .claude/ directory that instructs Claude Code to watch for specific patterns and trigger messages or blocks.

Guides users in creating custom Hookify rules to define automated patterns, warnings, and guardrails for Claude Code operations.

This skill provides specialized guidance for authoring Hookify rules, which are markdown files with YAML frontmatter that control Claude Code's behavior. It enables developers to implement project-specific guardrails by monitoring bash commands, file edits, and user prompts. By mastering regex patterns and event-driven conditions, users can automate safety checks—such as preventing dangerous shell commands or flagging debugging code—ensuring higher code quality and operational security within the Claude Code environment.
