Hook Development

Event-driven automation hooks are built by creating custom hook configurations and scripts that trigger on specific Claude Code events, enabling policy enforcement and context integration through the advanced prompt-based hooks API.

Command hooks perform deterministic checks to validate inputs and block dangerous commands, while prompt hooks leverage LLM-driven reasoning to evaluate complex conditions and enforce security policies dynamically.

You can prevent insecure file operations by implementing a PreToolUse hook that validates bash commands for safety, automatically blocking writes to system files or prompting for confirmation before executing risky commands.

Yes, prompt-based hooks support custom security policy enforcement by utilizing LLM-driven reasoning to evaluate tool inputs, validate context, and block dangerous commands or insecure file operations before execution.

No external dependencies are required to create custom Claude Code plugins. The Skill provides comprehensive guidance using built-in scripts, references, and assets to implement event-driven automation and validation logic independently.

Event-driven hooks should be used when you need to trigger automated validation logic before tools run or when agents stop, ensuring workflows remain secure and compliant with custom policies during interactive sessions.
