Tessl helps AI agents stay reliable and aligned by grounding their work in specs. Agents are powerful, but they can drift — misinterpreting requests, hallucinating APIs, or breaking existing features when adding new ones. Tessl integrates with most agents and uses spec-driven development to give agents (and you) a structured way to capture intent, run tests, and evolve codebases with fewer mistakes.
