Tessl

Tessl is a platform designed for teams looking to build AI-native software. It provides coding agents with structured, versioned context, enabling them to behave consistently across tools and projects. Tessl's approach focuses on giving agents the necessary context to develop software effectively, rather than just relying on prompting.
Tessl works by allowing users to find, install, version, and evaluate the skills and context their coding agents rely on. This is achieved through the Tessl Registry, which contains thousands of evaluated skills. The platform also enables users to create skills once and use them across all agents and models, streamlining the development process.
Tessl is particularly valuable for agentic developers and teams working on large-scale AI projects. These teams can benefit from Tessl's ability to drive up to 3.3X improvement in agents' use of over 300 libraries, leading to more efficient and effective software development. By providing a single source of truth for skills and context, Tessl helps teams scale agentic development across their organization.
