hook-development

To create Claude Code hooks, you develop event-driven scripts that trigger custom logic on specific events like PreToolUse or PostToolUse. This approach facilitates advanced automation, validation, and policy enforcement directly within your plugin workflows.

Yes, you can validate file operations and prevent dangerous commands by implementing PreToolUse hooks. These hooks provide security guardrails that allow you to approve or deny tool use based on your custom validation logic before execution.

The best way to automatically run unit tests after file modification is by configuring a PostToolUse hook. This event-driven pattern triggers your test suite immediately after a tool completes, ensuring code integrity before the next step.

You configure Claude Code plugin hooks by defining specific configuration formats that manage input/output handling and environment variables. This setup allows your scripts to securely receive event data and execute validation logic efficiently.

Yes, Claude Code supports both prompt-based and command-based hooks for plugin development. This allows you to choose the appropriate hook type to handle different event types and implement custom logic for your specific automation needs.

Event-driven hooks in Claude Code require careful implementation to avoid execution bottlenecks. You can apply specific debugging strategies to monitor hook behavior, identify configuration issues, and ensure your security policies perform reliably.
