Hook Development

What problem does it solve?

This Skill empowers you to automate complex workflows, enforce policies, and integrate external tools directly within Claude Code by leveraging event-driven hooks.

Core Features & Use Cases

• Event-Driven Automation: Execute custom logic in response to specific Claude Code events (e.g., before a tool runs, after a tool completes, when a session starts).
• Policy Enforcement: Implement security checks, validate inputs, and block dangerous commands.
• Context Management: Load project context, persist environment variables, and manage session state.
• Use Case: Automatically run linters and formatters on code edits, validate that tests are executed before stopping, or ensure sensitive commands are approved by the user.

Quick Start

Use the hook development skill to create a PreToolUse hook that validates file write operations for security.
