hook-development

You build event-driven hooks for Claude Code plugins using a standardized framework that executes custom logic across the development lifecycle, validating tool usage and session events. It combines deterministic bash-based commands with intelligent prompt-based validation logic.

Yes, you can validate file write operations before they execute by implementing a PreToolUse hook configuration. This creates a security guardrail that automatically checks file write safety for your current project to ensure project integrity.

Blocking dangerous bash commands in automated workflows is best achieved through deterministic command-based hooks. This approach provides secure, portable, and performant plugin extensions that validate tool usage before execution.

Hook development requires the jq dependency to process configuration and logic. The framework provides standardized configuration and testing utilities to ensure your plugin extensions remain portable and performant across your environment.

Use prompt-based hooks when you need intelligent, context-aware reasoning for complex validation. Use deterministic command-based bash hooks when you prioritize speed and need straightforward validation logic for tool usage and session events.
