Do I need to restart my session after updating hooks?

Yes, most hook registrations in the settings.json file require a new session to take effect properly.

Can these hooks integrate with external APIs?

Yes, the templates include patterns for External Integrators that can communicate with MCP servers, HTTP APIs, or WebSockets during any hook event.

How do I block a dangerous command using this skill?

Use the Gate Pattern within a PreToolUse hook. By returning exit code 2, the hook blocks the command and sends a specific error message back to Claude.

What are Claude Code hooks?

Hooks are specialized scripts triggered by Claude Code lifecycle events, such as before a tool is used or after a session starts, allowing for custom automation and validation.

What is the benefit of the State Manager role?

It allows you to create and track state files throughout a session, helping Claude understand which phase of a complex workflow it is currently executing.

Productivity & Workflow

Automates Claude Code workflows with production-tested hook patterns for validation, state management, and external tool integration.

About

Hook Templates provides a comprehensive framework for extending Claude Code's native capabilities through lifecycle event hooks. It enables developers to implement sophisticated logic such as 'gates' to block risky commands, 'side effects' for automated linting or commits, and state management systems that track workflow phases. By leveraging these patterns, users can create reliable agentic workflows with orchestration techniques like forced evaluation and context injection, ensuring Claude operates within defined safety and operational boundaries.

Key Features

Automated side effects like formatting, linting, and git commits
Pre-defined patterns for workflow gates and safety validation
External integration patterns for MCP calls and HTTP APIs
0 GitHub stars
State management templates to track complex multi-step processes
Orchestration templates for reliable skill and agent activation

Use Cases

Blocking destructive commands or requiring specific prerequisites before tool execution
Injecting specific project context or activating services at the start of a session
Automatically formatting code and creating commits after Claude performs an edit
