What Tessl does
Tessl is an agent enablement platform that gives coding agents structured, versioned context through a control plane for skills, loops, and context. Engineering teams building AI-native software use its Registry to index skills across an organization and reduce duplicates, and its visibility tools show how context activates across projects with before-and-after evaluations. Security scanning checks agent context for vulnerabilities against organization-defined standards, and prebuilt loops automate code review, documentation upkeep, test-and-fix work, and incident post-mortems. Teams can switch model providers through configuration and evaluate models on their own tasks. The company lists Cisco, Zillow, and Intercom as customers. A free starting tier includes 1,000 credits a month, and paid plan prices are not listed.
