Ship on evidence, not vibes
A score that moves with quality, so release decisions stop being an argument about who tried the scarier prompt.

Why agents need a different kind of testing
Conventional tests assume that identical input yields identical output. Agents break that assumption, so the usual green tick tells you almost nothing. Assurance replaces it with measurement: curated golden sets that encode what good looks like, graded rubrics calibrated against human judgement, adversarial suites that probe for injection and tool abuse, and production tracing that catches the drift no offline suite predicted. The result is a number that moves when quality moves, and a gate that stops a regression before your customers find it.
