Tessl is an agent-enablement platform that gives engineering teams a management layer for AI agent skills and plugins: continuously build, test, distribute, and optimize the context that coding agents rely on, with the security and governance of enterprise software. It centers on the Tessl Registry (3,000+ public skills plus private workspaces), the Tessl CLI, a first-party MCP server and workspace MCP gateway, Snyk-powered security scanning with install policies, and quality reviews and evaluations that can gate skills in CI. Skills and plugins are agent-agnostic, working across Claude Code, Cursor, Copilot, Gemini, and others. Founded by Guy Podjarny (Snyk); backed by Accel and GV.
