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 047 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-047
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-047 .claude/skills/mk-047

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

Use it in TypingMind

Enable Mk 047 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 047 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 047 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-047 | Price-survey response review

For a regular chat, upload packs/mk-047.md. It includes the shared rules, this method, and required references

Purpose

This skill delivers: A list of missing values, contradictory responses, and outliers

Curve intersections, cost floors, and launch decisions are distinct tasks; a price intersection does not guarantee maximum profit

Required inputs

Provide: Wording of the four PSM questions, currency and response format, raw answers, deidentified response keys, sampling and segments; supplied costs or market prices are range references only

Method

First check that all four PSM questions concern price acceptance and that their directions have not been reversed
Price levels must span a reasonable range from cost to the high end of comparable competitors. A range that is too narrow distorts interpretation of intersections
Retain the original customer group/Persona for each response so audiences can later be compared. Flag missing or clearly invalid answers first; do not fill in values yourself

Calculations and interpretation

Check sampling, valid responses, and the ordering of price questions; willingness to pay is neither actual purchasing nor a profit guarantee

Required output fields

Order	Field	How to complete
1	Anonymous response key and four original prices	Use the supplied source, calculation, or explicit unknown
2	Question meaning and currency	Use the supplied source, calculation, or explicit unknown
3	Missing, inconsistent or unusual response	Use the supplied source, calculation, or explicit unknown
4	Keep/exclude rule and reason	Use the supplied source, calculation, or explicit unknown
5	Segment	Use the supplied source, calculation, or explicit unknown
6	Valid count after cleaning	Use the supplied source, calculation, or explicit unknown
7	Open issues and preserved original values	Use the supplied source, calculation, or explicit unknown

Verification cases

MK-047-A1 | One of four prices is missing

Expected: Preserve original values, flag the gap and apply stated validity rules without imputation

English translation of source excerpt:

Van Westendorp's PSM (Price Sensitivity Measurement) fundamentally asks about the target consumer's acceptance of a price. It asks not only whether a price is expensive or cheap, but also which price is "too cheap"

Frequently asked questions

What does the Mk 047 AI skill do?

Price-survey response review. Use when the task requires a list of missing values, contradictory responses, and outliers. Apply this method to the specified inputs and verify the deliverable

Why use Mk 047 on TypingMind?

Because you install it once and use it with any model. Mk 047 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 047 in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/backtrue/thinkwithblack-skill/tree/main/en/skills/mk-047. 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 047?

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 047?

As many as you like. As long as a model supports skills, you can use Mk 047 with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Mk 047 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.
