FAQPage Schema
How do I configure Claude Code hooks for PreToolUse and PostToolUse events?

Configure Claude Code hooks by defining event matchers and commands for PreToolUse, PostToolUse, PermissionRequest, SessionStart, and Stop events to automate and validate tool workflows deterministically.

What are Claude Code hooks and when do I need them in my workflow?

Claude Code hooks are event-driven automation triggers that intercept tool actions at lifecycle stages like PreToolUse and Stop, needed when teams require deterministic validation, security checks, or custom behavior injection.

How do I debug Claude Code hook configurations that are not triggering?

Debug Claude Code hook configurations by validating event matchers, checking frontmatter-based skill identification, reviewing plugin hook integration patterns, and verifying that automation triggers align with expected lifecycle events.

Can I use Claude Code hooks to add security checks before tool execution?

Yes, Claude Code hooks support security considerations by attaching validation logic to PreToolUse and PermissionRequest events, allowing teams to intercept and review tool actions before execution proceeds.

What is the best way to integrate plugin hooks with Claude Code events?

Integrate plugin hooks with Claude Code events by referencing the provided templates and examples to design reliable, deterministic automation that extends default behavior across PreToolUse, Stop, and SessionStart events.

Do I need frontmatter-based identification to use Claude Code hooks?

Frontmatter-based skill identification ensures Claude Code hooks are correctly recognized and invoked, providing the structural metadata needed for reliable event matching and deterministic automation within workflows.
