Hook Development
PreToolUse and friends, in plugins
Anthropic · Apache-2.0
When
This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
The Catch
PreToolUse/PostToolUse/Stop hooks with ${CLAUDE_PLUGIN_ROOT}. Does not trigger without that plugin layout.
