What problem does it solve?
This Skill eliminates the steep learning curve and security risks of building Claude Code plugin hooks from scratch, providing proven patterns, validation tools, and best practices to create reliable, secure event-driven automation without trial and error.
Core Features & Use Cases
- Dual Hook Type Support: Implement both fast, deterministic command hooks and flexible, context-aware prompt-based hooks for all Claude Code events (PreToolUse, PostToolUse, Stop, SessionStart, etc.).
- Built-in Validation Tools: Includes pre-built scripts to validate hook configuration schemas, test hook behavior with sample inputs, and lint hook scripts for security vulnerabilities and best practice violations.
- Advanced Pattern Library: Access reference guides for complex use cases like multi-stage validation, cross-event state sharing, conditional hook execution, and integration with external systems like Slack or metrics tools.
- Use Case Example: A plugin developer can use this Skill to create a PreToolUse hook that blocks dangerous bash commands, or a SessionStart hook that automatically detects the project type and loads relevant context for the AI.
Quick Start
Use the Hook Development skill to create a PreToolUse hook that validates file write operations and blocks access to sensitive system paths and credential files.
