This is a prompt library that gives Claude structured frameworks for doing it. Picture pre-built consulting templates that turn Claude into a business analyst.

What's free: Everything. It's a collection of Claude Code skills (prompt files) you drop into your project. No install, no dependencies, no account.

The real value here is the structure. Instead of prompting Claude from scratch every time you need a SWOT analysis or process audit, these skills give it a repeatable framework. The prompts are well-organized and cover common business diagnostics.

The catch: it's brand new (almost all growth in the last week), the description is partially in Chinese, and the license is listed as 'Other' which means you should read it before using commercially. The skills are also opinionated. They assume a specific diagnostic methodology that may not match how you work. And since these are just prompt files, the barrier to building your own is low.
