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