hook-development

Event-driven automation for Claude Code plugins is set up by creating and managing hooks for events like PreToolUse, PostToolUse, and SessionStart through a hooks.json configuration. This enables automated workflows triggered by specific plugin events.

Yes, you can validate code changes before committing by setting up a PreToolUse hook. This hook uses prompt-based or command checks to enforce project quality standards and validate operations prior to execution.

Prompt-based hooks utilize LLM-driven decision making for context-aware validation, while command hooks execute deterministic bash commands for file operations and performance-critical tasks within your automation workflow.

Yes, implementing these hooks requires the Claude Code plugin environment and the ability to parse JSON input. This setup allows the hooks to process event data and execute validation or policy enforcement correctly.

You configure a PreToolUse hook by running the setup command with parameters for type, event, prompt, and timeout. For example, specify a 30-second timeout to limit the validation duration for your code changes.
