VinvAI runs and observes your services to find bugs and perf issues

Vinv says it gives a coding agent evidence from running Python services: recorded errors, argument values and the source locations involved. The project's stated workflow turns that evidence into a repair request, then runs the changed code to decide whether the repair passes.

Its acceptance tests are written before the fix and kept outside the fixing agent's view. They must fail twice on the original broken code before being used to assess a change, which is designed to reject tests that would pass regardless of the repair. That supplies a concrete check on an agent's completion claim. The page describes its FastAPI demonstration as one trial per condition, a demonstration rather than a benchmark, so it does not establish a general advantage over other debugging approaches.
