foster-fuzz

Fuzz-test the app, project or site at hand by driving its real UI like a crowd of realistic users. Maps every screen, flow and state, seeds a throwaway sandbox with believable and nasty data, then clicks, types, interrupts and resizes its way through looking for bugs, broken states and UI/UX problems. Produces a ranked findings report with screenshots and repro steps, and turns confirmed bugs into failing tests. Use when Greg says "fuzz", "fuzz test", "bash on it", "try to break it", "test-drive", "QA pass", or "find bugs in" an app, in Cursor, Claude Code, Codex or a cloud session.
