Skill Engineering

Skills are prompt templates that extend Claude with domain expertise. A skill lives in skill-name/SKILL.md with an optional references/ directory for deepening material. SKILL.md must be behaviorally self-sufficient — an agent reading only SKILL.md, without loading any references, must be able to do the job correctly. References provide depth, not breadth. Description triggers activation; instructions shape behavior. Claude sees only name and description at startup, then loads full SKILL.md content when triggered.
