Kessa is an open-source system for verifiable AI agent delegation and attestation. Every consequential agent action carries a signed chain of custody back to the human who authorized it, built so that authority can only narrow at each step, never expand. The core differentiator: an independent verifier that checks the evidence trail offline, trusting nothing about the system that produced it, not even the enforcement point itself. Self-hostable, stdlib-only Go, open source.

Top comment

Hey, maker here. Built this after running into a version of this problem with a client and not finding an answer I trusted. Happy to answer anything about the delegation model, the verifier design, or anything else. If you're running agents with any real authority (infra access, customer data, spend), I'd love to hear how you're thinking about accountability for what they do.
