You will need: Node.js

Checked against the repository on Sep 26, 2026, commit a334fac.

Text for your agent

Run npx skillkit@latest install ganzhamihail-jpg/mikhail-marketplace-skills, choose the target agent and directory, optionally add --skill with the names of the skills you need.

Other ways from the author
npx skillkit@latest install ganzhamihail-jpg/mikhail-marketplace-skills

Installs the whole set of eight skills.

This is third-party code. Review the repository files before installing.

What it does

Eight skills cover specific seller tasks: a Wildberries ad audit with ad-cost ratio and bid analysis, financial report reconciliation and a profit bridge, per-SKU unit economics with a break-even price and maximum ad-cost ratio, warehouse restocking and rebalancing, a weekly management profit report, Telegram post generation, lessons and exercises for training managers, and certificate and document-binding validation. Each skill takes numbers directly in the request (price, commission, logistics, cost) and calculates from them, rather than inventing missing metrics or platform rates.

Who it is for. For Wildberries and Ozon sellers who want quick calculations from their own numbers instead of manual Excel formulas.

Good fit when

  • You need to quickly compute unit economics, break-even price or maximum ad-cost ratio from your own figures
  • You need a weekly profit report or a WB ad campaign breakdown
  • You need a batch certificate check or a Telegram post for customers

Not a fit when

  • You need automatic data pulled from a seller cabinet: the skills work with numbers you supply yourself
  • You need Seller API integration: this bundle has none
  • The SkillKit installer doesn't fit: it needs Node.js 18 and npx

Example request

Use unit-economics: price 1990 rubles, commission 24%, logistics 145 rubles, cost 620 rubles, ads 180 rubles, tax 6%

Limitations

None of the skills connect to a marketplace Seller API: every calculation runs on numbers and files the user supplies in the request. Installation is built around SkillKit (npx skillkit) or manual copying, and the skill explicitly asks to verify current rates and platform requirements against primary sources rather than trust its own memory.

How to disable. Delete the relevant folder from skills/ in your agent's skills directory, or reinstall the bundle via npx skillkit@latest install without the unwanted skills.

Security check

  • Only calculates from figures and files the user provides, no access to platform accounts

README in short

The README lists the eight skills in a table, describes the layout (SKILL.md plus agents/openai.yaml per skill), installation via SkillKit as a whole set, by selected skills, or locally during development, gives test prompts for each skill, and states safety principles: never invent metrics, verify rates against primary sources, keep tokens out of the repository, and dry-run before a bulk upload.

FAQ

Do the skills pull data from a WB or Ozon cabinet themselves?

No, every calculation uses figures you supply in the request, the skills have no Seller API access.

Can I install just one skill?

Yes, npx skillkit@latest install supports a --skill flag with the names of the skills you need instead of the whole bundle.
