Event-driven hooks for Claude Code plugins are set up by defining prompt-based or command hooks for specific events like PreToolUse or PostToolUse. This framework ensures safety, policy compliance, and repeatable automation across sessions.

Claude Code hooks are used to enforce safety, policy compliance, and automated validation. They apply across PreToolUse, PostToolUse, SessionStart, and Stop events to manage access control and automated remediation workflows.

Yes, you can configure PreToolUse hooks to log tool usage and reject dangerous operations. This event-driven validation enforces safety policies and prevents unauthorized actions before they execute.

You test Claude Code hooks by following guided testing workflows within an active Claude Code session. This process validates hook formats and configurations to reduce errors and ensure repeatable behavior before deployment.

Prompt-based hooks and command hooks in Claude Code differ by their execution format. Both hook types support event-driven automation across PreToolUse and Stop events, but command hooks execute direct shell commands while prompt hooks use prompt-based logic.

You implement PostToolUse hooks when you need context enrichment or automated remediation after a tool executes. They capture event-driven outputs to enforce validation and policy compliance following tool completion.
