VIEW SOURCE →Agentic evaluation of live web apps, with a verifier that measures its own false-positive rate.
Five subagents drive real user journeys through a live web app and propose defects. A deterministic verification layer then decides which claims are real before anything reaches the report — every finding has to carry a replayable step sequence and one machine-checkable assertion, or it gets dropped.
The self-measurement is the point. Against a build with eight seeded defects: 15 raw agent claims, 7 published, 2 suppressed, a 0% false-positive rate against 14.3% for the same agents with the verifier removed, and 7 of 8 seeded defects found. The repo also ships an honest status doc on the six things it would need to actually be a product.
