Does this rating match your experience with mcp-builder?

Anonymous & aggregate. We watch these as a trend and re-check flagged skills — a single click never moves a grade on its own.

Independent static analysis by SkillMOO — the Consumer Reports for agent skills. Safety, token, and conflict grades are computed, not opinions. Efficacy is only ever claimed when measured. We rate & link to the source; we do not rehost skill content.
