Today, I’m excited to announce that you can evaluate your skills and optimize them.

This means you can stop debugging agent output and start shipping quality code, faster: Product Hunt launch

Agent skills help agents use your products, build in your codebase and enforce your policies.

They're the new unit of software for devs - but most are still treated like simple Markdown files copied between repos with no versioning, no quality signal, no updates.

Without AI evaluations, you can’t tell if a skill helps, provides minimal uplift or even degrades functionality.

You spend your time course-correcting agents instead of shipping.

Tessl is a development platform and package manager for agent skills. With Tessl, we were able to evaluate and optimize ElevenLabs' skills, 2x'ing their agent success in using their APIs.

If you are building a personal project, maintaining an OSS library, or developing with AI at work, you can now evaluate your skill and optimize it to help agents use it properly.

We’ve launched on Product Hunt launch! If you find it useful, we’d appreciate an upvote - and even more, your feedback in the comments:
