FAQPage Schema
How do I create a Claude Code hook to validate tool calls?▼

To create a Claude Code hook for tool validation, implement a PreToolUse hook using prompt-based or command-based APIs to intercept and validate tool calls, returning a permission decision to enforce safe automation.

What events are available for Claude Code plugin hooks?▼

Claude Code plugin hooks support events including PreToolUse, PostToolUse, Stop, and SessionStart, enabling developers to automate workflows and enforce safety checks at various stages of the execution lifecycle.

How do I use environment variables and paths safely in Claude Code hooks?▼

Use the CLAUDE_PLUGIN_ROOT environment variable for portable path references in Claude Code hooks to ensure secure integration, validating tool usage and loading memory without exposing sensitive environment data.

Can I build both prompt-based and command-based hooks for Claude Code automation?▼

Yes, Claude Code supports both prompt-based and command-based hooks, allowing developers to choose between context-aware validation prompts or direct command execution for automating workflows and enforcing security policies.

What are the best practices for testing Claude Code hooks?▼

Best practices for testing Claude Code hooks include validating tool-use decisions, verifying memory loading behavior, and ensuring secure integration with CLAUDE_PLUGIN_ROOT paths across all supported plugin events.

Why is my Claude Code hook not triggering on SessionStart or Stop events?▼

Claude Code hooks may fail to trigger if event names are misconfigured or if portable path references using CLAUDE_PLUGIN_ROOT are invalid, so verify event names like SessionStart and Stop and test your hook configuration.
