Don’t install someone else’s assumptions blind.

An AI skill is a set of instructions someone wrote for your AI. Some are useful. Some are generic, untested, or built on assumptions you would not choose yourself.

Once installed, a skill can shape decisions, read files, call tools, or touch real accounts. AI Skill Grader checks public GitHub skills before you add them to your workflow.

Why this exists

A README tells you what the skill claims.

It usually does not tell you what you need to know before install.

What can it touch? Can it change anything? What assumptions is it making? What should I test first? What should I not trust yet?

README says

“Helps with GTM planning.”

The point

Popular does not mean tested.

Open source does not mean good. Expert-written does not mean safe for your business.

We do not ask for API keys, tokens, private repo access, or production account credentials. We review public GitHub repos and direct SKILL.md files.

Reports are pre-install reviews, not certifications.
