Tessl

Tessl is a platform and command-line tool for developing software with coding agents. It provides structured, versioned context to help teams build AI-powered systems that work reliably in real codebases. The platform includes features for automated code review, skill optimization, security scanning, documentation maintenance, and agent evaluation. Developers use Tessl to design agentic workflows, manage and discover reusable skills across their organization, and monitor how agents perform. The platform emphasizes context as central to successful agent workflows, offering a registry to prevent duplicate skills and tools to catch regressions before they cause problems.

Tessl offers a free tier with 1,000 credits per month to get started, with paid options available for teams that need more. The platform includes built-in loops for common tasks like code review and skill optimization, while developers can also create custom loops tailored to their specific needs. Security scanning capabilities check for vulnerabilities in agent context before deployment.
