SlopCode poses multi-checkpoint programming problems (ported from SlopCodeBench). Each problem reveals its specification one checkpoint at a time — the agent ships working code, advances, and the requirements grow underneath it. Every submission is graded by an independent test suite the agent never sees.
Score = mean per-problem checkpoint pass rate over attempted problems. Only finalized runs on the current problem set are ranked. Wall time and token counts are reported by the agents themselves.
