Evaluate product demand from product links, product descriptions, PRDs, websites, app-store pages, white papers, sales decks, screenshots, or funding materials using the demand triangle model: lack, target object, and consumer ability. Use when asked for demand assessment, pre-investment product review, growth diagnosis, positioning validation, competitor-backed demand evidence, or a multi-format demand report. Do not use for pure market sizing, generic business-model design, UX-only review, legal/financial advice, or ad-copy ideation without demand evidence.

  • 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.

  • 39 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

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

Installation

Install the Yao Demand Skill 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.
2

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/yaojingang/yao-open-skills.git /tmp/yao-open-skills
mkdir -p .claude/skills
cp -r /tmp/yao-open-skills/skills/yao-demand-skill .claude/skills/yao-demand-skill
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Yao Demand Skill 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 Yao Demand Skill 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 Yao Demand Skill 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.

Yao Demand Skill

Evidence-backed demand assessment for products, services, apps, SaaS, AI tools, consumer goods, education products, and early-stage ventures.

Use This Skill For

  • assessing whether a product has a solid demand foundation before building, investing, launching, or scaling
  • diagnosing weak conversion, weak retention, vague positioning, pricing friction, trust friction, or adoption barriers
  • comparing direct competitors, indirect substitutes, current user workarounds, and the option of not buying
  • producing a visual demand diagnosis report with citations, scores, red flags, 10+ chart modules, experiments, forecasts, and four final formats

Do Not Route Here

  • pure TAM/SAM/SOM market sizing without product-demand diagnosis
  • generic monetization or business-model option design; use a business-model skill instead
  • UX heuristic review without demand, JTBD, or adoption evidence
  • legal, financial, medical, or investment advice as a final decision
  • manipulative marketing designed to shame, scare, addict, or exploit vulnerable users

Workflow

  1. Confirm the product input. Accept a URL, text description, PRD, website copy, docs, screenshot, app-store page, sales material, or funding deck. Ask only one concise question if no product substance is available.
  2. Build the product canvas: product definition, user, scenario, features, price, promise, business model, market, source list, and unresolved assumptions.
  3. Plan evidence. Prioritize official sources, third-party validation, user feedback, competitor/substitute evidence, and time-sensitive market or regulatory facts.
  4. Research only evidence that can support or challenge demand. Current product, price, competitor, market, legal, or regulatory facts must be verified with sources and dates.
  5. Segment users by JTBD, trigger scenario, buying role, current alternatives, and adoption blockers.
  6. Analyze the three demand triangle dimensions: lack, target_object, and consumer_ability. Include evidence, counter-evidence, assumptions, and improvement paths.
  7. Score each dimension from 0 to 10, then calculate total score with the geometric short-board formula and confidence adjustment.
  8. Produce visual diagnostics: at least 10 chart modules, each with one or two insight sentences, one recommendation, confidence, and evidence or assumption binding.
  9. Produce recommendations, forecast scenarios, and a final 30/60/90 day action plan: positioning, product, pricing, onboarding, trust, channel, and validation experiments.
  10. Run QA: citation coverage, time consistency, evidence diversity, at least three counter-signals, score explainability, chart completeness, ethics, and layout readiness.
  11. Write a structured report JSON, then use scripts/render_report.py to create Markdown, HTML, Word, and PDF outputs.

Output Contract

  • Always produce the final report in four formats: .md, .html, .docx, and .pdf.
  • Use one canonical report.json as the rendering source when possible, so the four outputs remain consistent.
  • HTML must include a top follow menu bar that stays pinned while the page scrolls, with quiet anchor navigation.
  • Formal reports must follow a summary -> visual diagnostics -> deep analysis -> final plan structure.
  • Formal reports must include at least 10 chart modules. HTML/PDF render them as inline SVG. Markdown and Word must include chart-equivalent tables or images.
  • All report backgrounds are pure white. Borrow Kami's editorial hierarchy, ink-blue accent, table discipline, typography, spacing, and production checks, but override Kami's parchment background.
  • Every key factual claim must either cite a source ID or be labeled as an assumption.
  • Every score must include evidence, reasoning, uncertainty, and a concrete improvement path.
  • Forecasts must be scenario-based and labeled with assumptions and confidence. Do not present uncertain adoption outcomes as deterministic predictions.

Reference Map

  • Read references/workflow.md before starting an assessment.
  • Read references/evidence-policy.md before using sources, citations, or current facts.
  • Read references/triangle-model.md before scoring.
  • Read references/report-contract.md before writing the report JSON or final narrative.
  • Read references/kami-white-report-layout.md before rendering the four output formats.
  • Use templates/report.schema.json as the report JSON target.
  • Use scripts/score_triangle.py to calculate or verify weighted scores.
  • Use scripts/validate_report.py before rendering.
  • Use scripts/render_report.py to generate Markdown, HTML, Word, and PDF.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Yao Demand Skill AI skill do?

Evaluate product demand from product links, product descriptions, PRDs, websites, app-store pages, white papers, sales decks, screenshots, or funding materials using the demand triangle model: lack, target object, and consumer ability. Use when asked for demand assessment, pre-investment product review, growth diagnosis, positioning validation, competitor-backed demand evidence, or a multi-format demand report. Do not use for pure market sizing, generic business-model design, UX-only review, legal/financial advice, or ad-copy ideation without demand evidence.

Why use Yao Demand Skill on TypingMind?

Because you install it once and use it with any model. Yao Demand Skill 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 Yao Demand Skill in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/yaojingang/yao-open-skills/tree/main/skills/yao-demand-skill. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Yao Demand Skill?

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 Yao Demand Skill?

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

Is the Yao Demand Skill AI skill free?

Yes. It is published on GitHub by yaojingang 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.
