Evaluation notes

What to check before installing

What OpenAgentSkill adds

OpenAgentSkill is designed as an application layer around discovery and decisions. It helps builders move from a task to a ranked shortlist instead of browsing a flat list.

  • +Search by job-to-be-done, not only by skill name.
  • +Use quality, freshness, GitHub stars, and installability as decision signals.
  • +Open decision pages that show risks, implementation paths, and alternatives.

How to compare marketplaces

A skills marketplace is useful when it helps users install the right thing faster. Traffic matters, but decision quality, SEO coverage, and repeatable workflows create durable value.

  • +Check whether searchers can land on use-case, install, and comparison pages.
  • +Check whether each skill has enough context to make an adoption decision.
  • +Check whether agents can consume the marketplace through an API.
