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.
2 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by backtrue on GitHub. Read the source before you install it.

Installation

Install the Mk 085 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.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/backtrue/thinkwithblack-skill/tree/main/en/skills/mk-085
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/backtrue/thinkwithblack-skill.git /tmp/thinkwithblack-skill
mkdir -p .claude/skills
cp -r /tmp/thinkwithblack-skill/en/skills/mk-085 .claude/skills/mk-085

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Mk 085 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 Mk 085 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 Mk 085 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.

MK-085 | Expanding audiences for the same product

For a regular chat, upload packs/mk-085.md. It includes the shared rules, this method, and required references

Purpose

This skill delivers: New user groups to test for the same product

Products occurring in the same transaction do not establish psychological motives; a product pairing does not automatically prove cross-selling effectiveness

Required inputs

Provide: Product capabilities and limits, current audience and uses, customer/market need signals, stock and costs; records of new-use orders if available

Method

List demonstrated capabilities, limitations and current uses
Find different uses in customer wording, service records or market questions, then identify possible roles without inferring identity from age or one purchase
Check whether the existing product can complete each job, required conditions and counterexamples; retain unmet needs
Prioritize by need evidence and supply capacity, specify observable validation, and check cost/outcomes when actual orders exist

Calculations and interpretation

Product selections and next-need proposals are candidates; check inventory, gross margin, existing buyers, and sales data

Required output fields

Order	Field	How to complete
1	Product capabilities and evidence	Use the supplied source, calculation, or explicit unknown
2	Current use and audience	Use the supplied source, calculation, or explicit unknown
3	Candidate new use and role	Use the supplied source, calculation, or explicit unknown
4	Observed need signals	Use the supplied source, calculation, or explicit unknown
5	What the existing product can and cannot meet	Use the supplied source, calculation, or explicit unknown
6	Stock and contribution conditions	Use the supplied source, calculation, or explicit unknown
7	Validation question, method and revision condition	Use the supplied source, calculation, or explicit unknown

Verification cases

MK-085-A1 | Customers use the product for another evidenced job

Expected: Deliver a role/use candidate, limits and validation, not merely a lookalike audience

Frequently asked questions

What does the Mk 085 AI skill do?

Expanding audiences for the same product. Use when the task requires new user groups to test for the same product. Apply this method to the specified inputs and verify the deliverable

Why use Mk 085 on TypingMind?

Because you install it once and use it with any model. Mk 085 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 Mk 085 in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/backtrue/thinkwithblack-skill/tree/main/en/skills/mk-085. 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 Mk 085?

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 Mk 085?

As many as you like. As long as a model supports skills, you can use Mk 085 with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Mk 085 AI skill free?

Yes. It is published on GitHub by backtrue 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.
