hooks

Claude Code hooks enable event-driven automation by intercepting lifecycle events like PreToolUse and PostToolUse. You need them to enforce policies, validate tool inputs, and ensure secure execution before or after automated actions run.

To configure a PreToolUse hook in hooks.json, define the event type and bind it to your automation script. This skill provides reference patterns and frontmatter usage examples to correctly structure the hook configuration for safe execution.

Yes, Claude Code hooks can be implemented across plugins, skills, and agents. The hook system supports unified configuration for events like SessionStart and Stop, allowing consistent policy enforcement and troubleshooting across all components.

A PostToolUse hook fails to trigger when the hooks.json integration is misconfigured or frontmatter is missing required event bindings. This skill provides troubleshooting references to identify configuration errors and validate correct hook behavior.

Safety considerations for Claude Code hooks include validating all tool inputs in PreToolUse, restricting agent permissions, and auditing Stop event triggers. Following established best practices prevents unauthorized actions and ensures secure automation workflows.

Yes, this skill includes rich reference materials and sample configurations for Stop and SessionStart events. These examples demonstrate practical hook patterns, frontmatter usage, and troubleshooting steps to speed up secure automation.
