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.
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.

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.
