Skill: Lean Canvas Generator

Use when starting a new product idea. Generates a structured lean canvas to force clarity on the business model before any code is written.

Trigger

Invoke this skill when the user says they have a new product idea, want to explore a business concept, or needs to articulate their value proposition.

Process

1. Ask the user to describe their idea in 2-3 sentences.
2. Generate a lean canvas covering all 9 blocks.
3. Challenge any block that relies on assumptions without evidence.
4. Save the canvas to docs/canvases/[idea-slug]-canvas.md.

Rules

• If the user cannot fill "Unfair Advantage," that is fine for now — but flag it as a long-term risk.
• Challenge any revenue estimate that assumes more than 1% conversion rate without evidence.
• The canvas is a living document. Update it as validation data comes in.
