Skill: Prototype

Use this skill when uncertainty is cheaper to answer with a small runnable artifact.

Rules

• Mark prototype as throwaway unless user asks to harden it.
• Keep it isolated from production paths where possible.
• Optimize for learning, not polish.
• Build multiple distinct UI variants when visual direction is unclear.
• Build terminal or unit-test harness when logic/state is unclear.
• Record what was learned and what must change before production.

Exit Criteria

• Question answered.
• Tradeoffs visible.
• Production path identified.
• Prototype cleanup or promotion decision made.
