HelloSurgeAI updated its sudo L7 leaderboard, which tests coding agents on real engineering tasks in private production codebases: Claude Opus 5.5 and Sonnet 5.5 lead at 41.7%, Gemini 4 Argon debuts at 18.9% (#7), and Muse Wonder scores 15.6% (tied #8). The benchmark emphasizes engineering judgment—writing idiomatic Rust, recognizing that logging banking credentials is bad practice, proactively flagging security risks—arguing that writing great code and being a great engineer are different things. echen quipped: easy is faster FFT; hard is convincing your PM that logging customer banking creds isn't a debugging strategy.
