ReflexQA

ReflexQA is a recursive, self-improving code QA agent. The speed at which we can push code has exponentially increased. The speed at which we can review code hasn't changed. I pointed this project at Meta's largest open-source project, React, and its GUI components. Meta Muse Spark is the Driver: it reads each test case off the screen and performs the steps in a real Chromium browser by clicking, typing and choosing options. SubQ Snap is the Judge, Router and Memory: on every step it reads about 189K tokens of React DOM’s real source plus the agent’s full history and before/after screenshots, then returns calibrated probabilities that decide PASS/FAIL against React’s expected result. The agent improves itself by turning passing runs into skills that replay with zero Meta calls (2.9× faster), writing lessons that later runs use, and letting SubQ choose its next test from 31 untested React cases, all for 6 Meta calls and $0.045 of SubQ per campaign.
