Key features of Tessl include the ability to evaluate skills from any GitHub repository, adding them to an open registry where they can be installed, tested, and assessed for performance. This process not only aids in due diligence for code usage but also contributes to the community by expanding the public registry. Tessl's platform is designed to streamline the development process by identifying discrete, reusable skills, making it an essential tool for developers looking to enhance their projects with verified agent skills.

Overview:

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.
