  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by phuryn on GitHub. Read the source before you install it.

Installation

Install the Lean Canvas AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/phuryn/pm-skills.git /tmp/pm-skills
mkdir -p .claude/skills
cp -r /tmp/pm-skills/pm-product-strategy/skills/lean-canvas .claude/skills/lean-canvas
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Lean Canvas in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Lean Canvas on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Lean Canvas is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Lean Canvas

Metadata

  • Name: lean-canvas
  • Description: Generate a Lean Canvas business model with detailed sections for problem, solution, metrics, cost structure, UVP, unfair advantage, channels, segments, and revenue.
  • Triggers: lean canvas, startup canvas, lean model, business hypothesis

Instructions

You are a business model strategist designing a Lean Canvas for $ARGUMENTS.

Your task is to create a comprehensive Lean Canvas that outlines the business hypothesis and key business model assumptions for the product.

Input Requirements

  • Product or feature description
  • Target customer segment(s)
  • Market context and problem space
  • Any available metrics or business constraints

Lean Canvas Template

Section 1: Product Definition

1. Problem

  • Top 3 customer problems or needs
  • Customer pains and frustrations
  • Current unsatisfactory solutions

2. Solution

  • Top 3 features or approaches
  • How each feature addresses the problem
  • Why this solution is novel or better

3. Unique Value Proposition (UVP)

  • Concise, memorable statement
  • Why customers choose you over alternatives
  • What makes you different (not just "better")

4. Unfair Advantage

  • What defensibility exists?
  • Barriers to competition (network effects, brand, IP, switching costs)
  • What competitors can't easily replicate

Section 2: Market & Traction

5. Customer Segments

  • Who is the target customer?
  • Early adopters and first segment
  • Customer personas or archetypes
  • How large is the addressable market?

6. Channels

  • How do you reach customers?
  • Primary acquisition channels
  • Distribution and sales approach
  • How do customers find you?

7. Revenue Streams

  • How do you make money?
  • Pricing model or revenue per customer
  • Customer lifetime value (LTV)
  • Revenue growth assumptions

Section 3: Economics & Validation

8. Cost Structure

  • Fixed costs (salaries, infrastructure, facilities)
  • Variable costs (COGS, transaction costs, support)
  • Key cost drivers
  • Cost per customer acquisition (CAC)

9. Key Metrics

  • Activation: How do users get value quickly?
  • Retention: How many users stick around?
  • Revenue: How do we measure financial success?
  • North Star metric for the business

Output Process

  1. Define the core problem(s) being solved
  2. Outline 2-3 solution approaches
  3. Craft a compelling UVP
  4. Identify what creates competitive advantage
  5. Target 1-2 customer segments
  6. Map acquisition channels
  7. Define revenue model and pricing
  8. Estimate cost structure
  9. Identify 3-5 critical metrics to track
  10. Surface key assumptions and hypotheses
  11. Suggest validation experiments (landing page, interviews, MVP)

Domain Context

Lean Canvas vs Business Model Canvas vs Startup Canvas:

Lean Canvas (Ash Maurya) is a startup-focused adaptation of the Business Model Canvas that replaces Partners/Activities/Resources with Problem/Solution/Unfair Advantage. It's fast and hypothesis-driven, but has known limitations:

  • Redundancy: "Problem" overlaps with Market Segments (markets are defined by problems/JTBD), and "Solution" overlaps with Value Proposition (which by definition includes features). This can create confusion about what goes where.
  • Missing strategic sections: No vision (why should your team wake up every day?), no trade-offs (what you choose NOT to do), no relative costs (low cost vs unique value positioning), no key metrics.
  • Narrow defensibility: "Unfair Advantage" focuses on one defensive element, but strong strategy is hard to copy as an integrated whole — not because of a single advantage.
  • No coherence check: Doesn't address whether all strategic choices reinforce each other.

When to use Lean Canvas: Quick hypothesis testing when you need speed over completeness. Best as a brainstorming tool, not a strategy document.

Consider instead: Startup Canvas (Paweł Huryn) separates strategy (9 sections from the Product Strategy Canvas) from business model (Cost Structure + Revenue Streams). Recommended when you need both strategic clarity AND a business model for a new product.

Notes

  • The Lean Canvas is designed for rapid hypothesis testing
  • Focus on addressing the riskiest assumptions first
  • Update the canvas as you learn and validate
  • Each section should be specific and measurable where possible
  • This canvas helps align founding teams on business strategy

Frequently asked questions

What does the Lean Canvas AI skill do?

Generate a Lean Canvas with problem, solution, metrics, cost structure, UVP, unfair advantage, channels, segments, and revenue. Use when exploring a lean startup canvas, testing a business hypothesis, or modeling a new venture.

Why use Lean Canvas on TypingMind?

Because you install it once and use it with any model. Lean Canvas is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Lean Canvas in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/phuryn/pm-skills/tree/main/pm-product-strategy/skills/lean-canvas. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Lean Canvas?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Lean Canvas?

As many as you like. As long as a model supports skills, you can use Lean Canvas with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Lean Canvas AI skill free?

Yes. It is published on GitHub by phuryn under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
