Can I automatically load project context on startup?

Yes, by using the SessionStart event, you can execute scripts that read files like CLAUDE.md or check git status, then inject that information directly into Claude's context.

What are Claude Code hooks?

Hooks are specialized event handlers that trigger scripts or LLM prompts at specific points in a Claude Code session, such as before a tool runs or when a session starts.

What is the difference between command and prompt hook types?

Command hooks execute local bash scripts for logic and validation, while prompt hooks use the LLM itself to evaluate whether an action should proceed based on instructions.

How do I block dangerous commands using hooks?

You can implement a PreToolUse hook that uses a bash script to inspect command inputs. If a forbidden pattern is found, exiting the script with code 2 will block the action.

Productivity & Workflow

Automates Claude Code workflows by implementing event-driven hooks for tool validation, context management, and session control.

The Hooks Reference skill provides a comprehensive framework for extending Claude Code's functionality through event-driven automation. It allows developers to intercept tool executions, manage session lifecycles, and enforce custom security or workflow policies by tapping into events like PreToolUse, SessionStart, and Stop. By utilizing bash scripts or LLM-based evaluations, users can block dangerous terminal commands, automatically load project context from files like CLAUDE.md, and ensure all tasks are verified before a session concludes, creating a significantly more robust, secure, and personalized development environment.
