To create a Claude Code hook for validating file writes, you define a PreToolUse hook with specific matcher patterns and write a script to handle the event, ensuring deterministic automation that prevents accidental modification of sensitive system files.

Claude Code hooks are prompt-based or command-based scripts triggered by events like PreToolUse or Stop, needed for secure and context-aware automation when you want to enforce deterministic validation or execute custom logic during specific tool lifecycle stages.

Yes, you can adapt external hooks by modifying their configuration and script logic to match your environment, validating their security and functionality through detailed debugging workflows before integrating them into your hook lifecycle.

To debug a non-triggering Claude Code hook, review your matcher patterns for accuracy, verify the event configuration such as PreToolUse or Stop, and use the provided validation checklist to isolate configuration or scripting errors.

Prompt-based hooks use context-aware logic for flexible automation, while command-based hooks execute deterministic scripts for strict validation, with both supporting event handling and matcher patterns to trigger during the Claude Code lifecycle.
