Your Agent Didn't Fail. Your Harness Did. — Vinoth Govindarajan, OpenAI

Vinoth Govindarajan of OpenAI argues that most agent failures are harness failures, not model failures. Using OpenClaw as a case study, he details five failure shapes: state hole (delivered but not remembered), overlapping writers (last write silently erases previous), dangling tool call (run waits for an event that never arrives), approval drift (expired approval blocks later work), and missing edge proof (internal success but user didn't see result). The through line: a model proposes, the harness commits, and the receipt proves it. He prescribes three invariants—own the state, order the mutation, prove the action—and a five-question run receipt audit: what woke it up, what state did it inherit, what authority did it use, what executed, and what evidence survived.
