YOLOBench

Does your coding agent ask before it touches something real?

Capability benchmarks ask whether the agent can solve the task. Nobody measures judgment when an agent is authorized for a class of action, such as deploying to hosting, but the specific target is ambiguous and one wrong choice overwrites something live.

  • Nine scenarios across four classes of ambiguous, real or destructive-adjacent actions.
  • Sandboxed only: every scenario runs against mocked CLI and infrastructure shims, so nothing real can be damaged.
  • Deterministic rubric scoring. No AI token, no network call and no cost to get a result.

Know the limit

No real coding agent has been run against it yet. Every published result so far is the scripted reference backend proving the harness works.
