Which tools can I monitor with these hooks?

You can monitor any tool available to Claude Code, including Bash, Write, Edit, Read, Glob, Grep, Task, and custom Skills.

Can I block dangerous commands using this skill?

Yes, by creating a PreToolUse hook, you can implement logic that exits with code 2 and a message to the stderr, which prevents the tool from running.

What languages are used for the generated hooks?

The skill generates robust Bash scripts (shell) that utilize Python3 for efficient JSON parsing of tool inputs and responses.

What are Claude Code hooks?

Hooks are specialized scripts that execute during specific events in a Claude Code session, allowing developers to intercept, modify, or block tool executions and session behavior.

Do I need to manually update hooks.json?

No, the Create Hook skill automatically handles the registration of your new scripts in the hooks.json configuration file using the correct environment variables.

Developer Tools

Automates the creation, configuration, and registration of specialized Claude Code session hooks and guardrails.

The Create Hook skill is a developer utility within the Lore framework designed to streamline the lifecycle of Claude Code event hooks. It provides a guided workflow for selecting hook types—such as PreToolUse, PostToolUse, or SessionStart—configuring matchers for specific tool execution, and generating robust shell scripts with standardized error handling and JSON parsing. By automating the registration process in hooks.json using environment-aware paths, it enables developers to rapidly implement deterministic guardrails, quality gates, and custom automation without manual configuration errors.

Key Features

010 GitHub stars

02Support for blocking logic in PreToolUse hooks to enforce security and quality standards.

03Guided configuration for all Claude Code hook events (Pre/PostToolUse, SessionStart/Stop, UserPromptSubmit).

04Automated shell script generation with boilerplate JSON parsing and error handling.

05Tool-specific matcher configuration to target hooks at Bash, Write, Edit, or custom tools.

06Seamless integration and registration into the Lore framework's hooks.json configuration.

Use Cases

01Building custom session monitors that log tool outputs or provide real-time feedback to the AI.

02Creating automated code quality gates that validate file changes before they are finalized.

03Implementing security guardrails to block accidental secret leaks or destructive shell commands.
