Quick Review

Excellent comprehensive skill for Claude Code plugin hook development. The description clearly identifies trigger phrases and use cases. SKILL.md provides thorough coverage of hook types (prompt-based vs command), all event types, configuration formats, security best practices, and debugging workflows. Strong task knowledge with concrete examples, code snippets, and references to detailed files in references/ and examples/ directories. Well-structured with clear sections, quick reference tables, and logical progression from basics to advanced topics. High novelty as implementing event-driven hooks with LLM-based validation, security checks, and proper error handling would be complex and token-intensive for a CLI agent to accomplish without guidance. Minor room for improvement in explicitly calling out the two-format distinction (plugin vs settings) earlier, but overall this is a production-ready, well-documented skill.
