skill-mastery
Skill Mastery: The Ultimate Guide
Combines three authoritative sources into a unified approach:
- Official plugin-dev toolkit - Validation, patterns, AI-assisted creation
- Community best practices - Token hierarchy, archetypes, advanced patterns
- Official documentation - Current API fields, latest features
Mental Model: How Skills Actually Work
Skills use pure LLM reasoning for selection - no embeddings or keyword matching. Claude evaluates all skill descriptions via natural language understanding, making description quality critical.
Token Loading Hierarchy
Level 1: Metadata (~100 tokens) Always loaded at startup
name + description in system prompt
↓
Level 2: SKILL.md (~1,500-5,000 tokens) Loaded when skill triggers
