  • 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.

  • 1 bundled files

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

  • Open source

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

Installation

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

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.
    https://github.com/cnfeat/top-pm-skills/tree/main/参考skill/lenny-skills-main%20(2)/lenny-skills-main/skills/scoping-cutting
  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.

Use it in TypingMind

Enable Scoping Cutting 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 Scoping Cutting 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 Scoping Cutting 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.

Scoping & Cutting

Help the user scope projects and cut features effectively using frameworks from 15 product leaders.

How to Help

When the user asks for help with scoping:

  1. Understand the hypothesis - Ask what they're trying to learn or validate
  2. Identify the appetite - Determine how much time/resources they're willing to invest
  3. Find the essential core - Help them identify what must be present for the first version
  4. Design for learning - Ensure the scope enables fast feedback, not just fast shipping

Core Principles

Use appetite, not estimates

Ryan Singer: "We're going to go the other way around and we're going to say, what is the maximum amount of time we're willing to go before we actually finish something?" Set a fixed time budget (appetite) and design a version of the solution that fits within it. Vary scope, not deadlines.

MVP is a validation tool

Eric Ries: "MVP is simply for whatever the hypothesis is that we're trying to test, what is the most efficient way to get the validation we need about whether a hypothesis is true or not?" An MVP is not a low-quality product - it's the most efficient way to test a specific hypothesis.

Cut the list in half, then half again

Eric Ries: "Write out the list of features that are necessary in your MVP. Cut it in half and cut it in half again and build that." Founders consistently overestimate what's "minimum." Aggressive cutting is required to reach a true baseline.

Fixed time, small teams

Jason Fried: "Our appetite for any individual feature is no more than six weeks... So we have to figure out the simplest, most effective version of that to get that done within six weeks and get it done by two people." Constraints force creative solutions. Limit team size to maintain focus.

Build the scooter, not the axle

Eeke de Milliano: "If you're trying to build the minimum viable product for a car, don't build just the wheels and the axle, build the scooter first." An MVP should be a functional, end-to-end version of a smaller value proposition, not an incomplete piece of a larger one.

Use Wizard of Oz testing

Crystal W: "It's really this Wizard of Oz experience. We don't have to build anything. I coordinated with a bunch of interns and we were able to validate some of the value prop." Validate value propositions manually before investing in engineering. Use humans to simulate automated features.

Kill projects that don't finish in time

Jason Fried: "If there's any work that's left over that's still on the left side of the hill, meaning we're still pushing it up, we don't know how we're going to do it and we're at our time limit, it almost certainly dies." Let projects die if they aren't completed within their allotted time to prevent never-ending work.

Build the option to pivot into the process

Paige Costello: "We added into our product process a notion that we might pivot or cut from stuff that we put on our roadmap because it felt like once it was on the roadmap, it had to be done." Formalize the ability to cut or pivot from roadmap items to avoid the sunk cost fallacy.

Questions to Help Users

  • "What's the single hypothesis you're trying to validate with this version?"
  • "What's the maximum time you're willing to invest before shipping something?"
  • "What would you cut if you had to ship in half the time?"
  • "Is there a way to test this manually before building automation?"
  • "If this feature doesn't ship in time, will you kill it or extend?"
  • "What's the smallest thing that still delivers complete value?"

Common Mistakes to Flag

  • Estimating instead of time-boxing - Asking "how long will this take?" instead of "what can we do in X weeks?"
  • Building the axle - Shipping incomplete parts of a larger feature instead of complete smaller features
  • Never killing projects - Extending deadlines instead of cutting scope or canceling
  • Over-engineering the MVP - Building too much before testing the core hypothesis
  • Ignoring the Wizard of Oz - Always defaulting to building when manual validation would be faster

Frequently asked questions

What does the Scoping Cutting AI skill do?

Help users scope projects and cut features effectively. Use when someone is defining an MVP, dealing with scope creep, trying to ship faster, or needs to make tradeoffs about what to build.

Why use Scoping Cutting on TypingMind?

Because you install it once and use it with any model. Scoping Cutting 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 Scoping Cutting in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/cnfeat/top-pm-skills/tree/main/参考skill/lenny-skills-main%20(2)/lenny-skills-main/skills/scoping-cutting. 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 Scoping Cutting?

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 Scoping Cutting?

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

Is the Scoping Cutting AI skill free?

Yes. It is published on GitHub by cnfeat 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.
