claude-code-hooks

The 'claude-code-hooks' skill provides a guide for implementing automated hooks within the Claude Code environment. These hooks allow users to execute bash commands or TypeScript scripts in response to various workflow events, facilitating custom behavior at key points in the workflow. This skill solves the problem of automating tasks such as validation, formatting, context injection, and session management during the execution of Claude Code. Developers can leverage this functionality to fine-tune their workflows and ensure greater automation, efficiency, and security during tool execution and agent interactions.

Key features include the ability to define hooks for nine distinct workflow events such as 'PreToolUse', 'PostToolUse', and 'SessionStart'. The hooks can be configured to perform actions like code formatting, security validation, environment setup, or user prompt modification. The integration of the 'claude-hooks-sdk' in TypeScript enhances type safety and simplifies development by providing utilities for managing hook events and ensuring consistent behavior across different hooks. The skill is flexible enough to be customized for a variety of tasks in different environments, making it suitable for a wide range of use cases.

Target users include developers working with Claude Code who need to automate tasks, enforce security policies, and manage workflows in an efficient and customizable way. Use cases range from code formatting (PostToolUse) and security validation (PreToolUse) to environment setup (SessionStart) and context injection (UserPromptSubmit). By using these hooks, developers can streamline processes, reduce errors, and ensure that their workflows remain consistent and secure.
