What it does

When you ask the agent to map out a startup or new product idea, this skill makes it fill in a Lean Canvas, a one-page business plan covering the customer problem, proposed solution, value proposition, unfair advantage, target customers, sales channels, revenue, costs, and key metrics. It also lists the riskiest assumptions and suggests quick experiments, such as landing pages, customer interviews, or a minimum viable product, to test them. The skill notes that Lean Canvas is best as a fast brainstorming tool and points to the Startup Canvas for deeper strategy.

Great for

  • Founders sketching a new venture quickly before committing time or money
  • Product managers testing a business hypothesis for a new feature or product line
  • Students learning the Lean Canvas framework and its limitations

Skip it if

  • Final investment or board-level strategy, since the skill itself says Lean Canvas is a brainstorming tool and lacks vision, trade-offs and coherence checks (use the Startup Canvas instead)
  • Financial forecasting or precise market sizing, because the skill only asks the agent to estimate figures from the information you give it and does not verify market data

Try asking

  • “Create a Lean Canvas for a subscription app that helps freelancers track invoices”
  • “Help me test the business hypothesis for a B2B tool that automates restaurant inventory”
  • “Model a new venture for an online tutoring marketplace and list the riskiest assumptions”
  • “Draft a lean startup canvas for a feature we are considering adding to our product”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Give the agent your target customer, the problem, and any known metrics or constraints up front so the canvas is specific rather than generic.
  • Ask for the riskiest assumptions and validation experiments at the end, then test the top one before refining the rest of the canvas.
  • Treat the output as a hypothesis to revise as you learn, and use the Startup Canvas skill if you also need strategy and trade-offs.
