Hook Development

To create Claude Code hooks, define event-driven automation policies in a hooks.json file. The hook policies configure validation and automation for events like PreToolUse, PostToolUse, Stop, and SessionStart across development workflows.

Claude Code plugin hooks are event-driven scripts that provide safety and workflow automation. You need hooks to enforce secure validation, block dangerous file writes, and trigger actions during development events like SessionStart or Stop.

Yes, jq is required to configure hooks.json schemas and validate hook policies. The dependency supports JSON schema configuration and processing for plugin-level and user-level settings files.

The best way to enforce security in Claude Code plugins is by creating PreToolUse hook policies with validation scripts. These scripts implement path safety, secret detection, and input validation before executing tools.

Yes, you can run Claude Code hooks in parallel with timeout management. Performance tips and configuration guidance support parallel execution, caching, and timeout limits to optimize development workflows.

To block dangerous file writes, create a PreToolUse hook policy that denies writes to system directories and asks for user approval. The hook enforces path safety and prompts for confirmation before execution.
