What is Tessl?

Tessl is an agent enablement platform that helps you get the most out of coding agents with reusable context called specs. Tessl provides a registry for distributing specs and it offers MCP tools that work with most agents to optimize their retrieval of specs while they work on tasks.

Agents are powerful, but they require good context to be effective—internal API documentation, styleguides, common testing workflows, etc. Without this information, agents misinterpret requests, hallucinate APIs, or break existing features when adding new ones.

• Public Registry (open beta): Version-aware usage documentation on 10,000+ widely used open-source libraries. Follow this link to get started.

• Private Registry (closed beta): Available to selected users. Create and distribute organizational context like internal API documentation, styleguides, etc.
