Hook Development

You build Claude Code hooks for tool validation by configuring a PreToolUse event hook that intercepts risky commands, applies validation rules, and reports decisions before execution proceeds. This Skill provides patterns for implementing these event-driven workflows safely.

Event-driven hooks in Claude Code are automation triggers that fire during specific lifecycle events like PreToolUse, PostToolUse, SessionStart, or Stop. They allow plugins to enforce workflows, run security checks, and validate actions automatically.

Yes, you can use command and prompt-based hooks together for Claude Code security checks. This Skill guides you through designing safer hook patterns that protect sensitive files and enforce development standards across both implementations.

Yes, you need jq and timeout installed to configure reliable Claude Code automation hooks. These dependencies support parsing validation outputs and enforcing time limits on hook processing for safer plugin integration.

The best way to automate session lifecycle events in Claude Code plugins is implementing SessionStart and Stop hooks with event-driven validation. This Skill provides configuration guidance for applying these patterns to enforce workflows and integrate custom behavior reliably.

You should add validation workflows to Claude Code hooks to prevent risky tool operations and protect sensitive files during automated sessions. Implementing PreToolUse security checks ensures commands are reviewed and clear decisions are reported before execution.
