Description
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 frameworks like LangGraph, AutoGen, CrewAI, or custom systems.I built this after repeatedly seeing reliability failures when AI agents interacted with production APIs.Would love feedback from anyone building agent systems.

Could you build this?
Yes The platform functions as an orchestration layer using Pipedream for tool execution, saving executed action paths, and applying idempotency keys and approval gates to agent runs.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
