Show HN: A package manager for agent skills with built-in evals

This resonates with my experience: we have dozens of internal “playbooks” and prompt snippets floating around, and nobody knows which ones still work after model changes. If you can make “skill quality” visible over time (regressions, drift), that’s valuable. Do you have a CI integration where you can pin a skill version and fail builds if eval scores drop?
At some point I thought skills were only markdown files
We’ve recently witnessed that most teams still treat skills as static artifacts: markdown files, created or copied from repo to repo.
This approach offers a strong initial boost, but quickly creates debt:
- Skills are duplicated, and updates never roll out. - Poor quality skills go unseen, misguiding agents instead of helping. - Skill knowledge grows stale, and don’t keep up with the systems and practices they describe.
Without a way to evaluate skills, teams have no clear way to understand how good a skill actually is, or if it degraded over time.
Our belief is that evaluations are the foundation for having quality skills.
With that in mind, I’m glad to announce that Tessl Registry contains review evals for over 2,000 skills, and you can request an evaluation for any public skill.
Super excited to be launching this — keen to get your feedback, and looking forward to the many more enhancements in the queue!
