Tessl

Tessl gives engineering teams one place to publish, find and evaluate the skills and versioned context their coding agents rely on. It aims to stop duplicate or low-quality skills from spreading and to catch regressions before they slow developers down.

The Tessl Registry indexes skills across your organization and private workspace, shows which ones agents actually activate, and runs before-and-after evals on every change. Teams can then chain skills into agentic loops and larger automated workflows, with the Tessl agent available on every plan.

Usage is billed in credits that cover reviews, evals and agent runs, with frontier models using credits faster. Enterprise adds bring-your-own LLM, single-tenant or self-hosted deployment, SLAs and implementation support.
