       Show HN: Kybernis - Prevent AI agents from executing the same
       action twice
        
       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
       once  Retries 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.

       | The core problem we're exploring is that AI agents are non-
       | deterministic systems operating inside deterministic
       | infrastructure.
       | 
       | Traditional systems assume actions run once.
       | 
       | Agents retry steps, re-plan tasks, and execute asynchronously.
       | 
       | That combination makes duplicate execution surprisingly easy.
       | 
       | Kybernis focuses on the execution boundary where agents trigger
       | real mutations (payments, infrastructure changes, APIs).
       | 
       | Curious if others deploying agents have run into similar
       | reliability issues.

       | problem at the execution boundary, ARU handles the output
       | validity problem upstream. These could be complementary layers.
       | Have you thought about pre-execution validation as part of the
