Profile

AI agents increasingly execute real system actions: issuing refunds, modifying databases, deploying infrastructure, calling external APIs.Because agents retry steps, re-plan tasks, and run asynchronously, the same action can sometimes execute more than once.In production systems this can cause duplicate payouts, repeated mutations, or inconsistent state.Kybernis is a reliability layer that sits at the execution boundary of agent systems.When an agent calls a tool:1. execution intent is captured 2. the action is recorded in an execution ledger 3. idempotency guarantees are attached 4. the mutation commits exactly onceRetries become safe.Kybernis is framework-neutral and works with agent frame

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

The company is listed at the Show HN launch stage of development.
