Skill instructions
Hook Development for Claude Code Plugins Overview Hooks are event-driven automation scripts that execute in response to Claude Code events. Use hooks to validate operations, enforce policies, add context, and integrate external tools into workflows. Key capabilities: - Validate tool calls before execution (PreToolUse) - React to tool results (PostToolUse) - Enforce completion standards (Stop, SubagentStop) - Load project context (SessionStart) - Automate workflows across the development lifecycle Hook Types Prompt-Based Hooks (Recommended) Use LLM-driven decision making for context-aware validation: json { "type": "prompt", "prompt": "Evaluate if this tool use is appropriate: $TOOLINPUT", "timeout": 30 } Supported events: Stop, SubagentStop, UserPromptSubmit, PreToolUse Benefits: - Context-aware decisions based on natural language reasoning - Flexible evaluation logic without bash scripting - Better edge case handling - Easier to maintain and extend Command Hooks Execute bash commands
