Did the Work Happen

Evaluate AI agents at the trajectory level — tool choice, argument validity, step efficiency, cost, and policy — and gate CI on a ship / hold / fix verdict. Six deterministic evaluators, framework-agnostic, Python, zero dependencies. The fourth dev-tools gate: agent behavior.

An 8-step agent at 85% per step succeeds end-to-end just 27% of the time. Reveals each workflow's true compounded success rate, catches quiet drift (observed vs. the chain math), and verdicts every agent STABLE / SHORTEN / CHECKPOINT with a fleet drift rate. Deterministic, offline. One .xlsx.
