Can I use hooks to block certain actions?

Yes, by using a PreToolUse hook and returning an exit code of 2, you can programmatically prevent Claude from executing specific commands or editing protected files.

Do I need to restart Claude Code after changing hooks?

Yes, Claude Code loads hook configurations at startup, so you must exit and relaunch the application for any changes to take effect.

What are Claude Code hooks?

Hooks are triggers that execute shell commands during specific events in the Claude Code lifecycle, such as before a tool is used or after a session starts.

Where are these hooks stored?

Hooks are stored in the Claude settings files, typically located at ~/.claude/settings.json for global settings or within a project's .claude/ directory.

Productividad y Flujo de Trabajo

Manages Claude Code life cycle hooks through natural language to automate development workflows and enforce custom safety rules.

Acerca de

Claude Hooks Manager provides a specialized interface for configuring Claude Code's event-driven hooks system using simple conversational commands. It enables developers to automate repetitive tasks—such as linting code after a write operation, logging bash history, or sending desktop notifications—by mapping shell commands to internal lifecycle events like PreToolUse and PostToolUse. With integrated validation and support for global or project-specific settings, it serves as a powerful tool for customizing the AI's behavior and integrating it deeply into existing local development environments.
