What event types can trigger a Hookify rule?

Rules can trigger on bash commands, file modifications (edit/write), user prompts, or 'stop' events when the agent attempts to finish a session.

How do I temporarily disable a rule?

You can toggle a rule without deleting the file by setting the 'enabled' field to 'false' in the rule's YAML frontmatter.

Where are Hookify rules stored?

Rules are stored as markdown files within the .claude/ directory of your project using the naming convention hookify.{rule-name}.local.md.

Can I prevent Claude from running specific commands?

Yes, by setting the 'action' field to 'block' in the YAML frontmatter, you can stop the agent from executing matching bash commands or file edits.

What regex syntax does Hookify use?

Hookify uses standard Python regex syntax. It is recommended to test patterns using a Python interpreter or online regex testers set to the Python flavor.

Security & Testing

Configures custom guardrails and automated notifications for Claude Code by defining event-driven patterns.

About

This skill provides comprehensive guidance for creating and managing Hookify rules, which are specialized markdown files that intercept and guide Claude Code's actions. It enables developers to define patterns across shell commands, file modifications, and session termination to enforce coding standards, prevent dangerous operations, and ensure project-specific checklists are followed. By utilizing regex patterns and specific event hooks, it creates a robust framework for AI safety and workflow automation within any development project.

Key Features

0 GitHub stars
Event hooks for prompts, file writes, bash tools, and session completion
Simple YAML frontmatter configuration for easy rule management
Multi-condition rule logic using field-level operators (regex, contains, starts_with)
Regex-based pattern matching for bash commands and file edits
Customizable actions to either warn the agent or block operations entirely

Use Cases

Enforcing code quality standards by flagging debug statements or sensitive data in specific file types
Preventing dangerous terminal operations like 'rm -rf' or unauthorized privilege escalation
Implementing mandatory completion checklists to ensure tests are run before the agent stops a task
