coding-agent / rank 23 of 41 / cycle 04

Codebuff benchmark

A terminal agent that spreads a task over several specialised sub agents, which keeps the median low and occasionally produces two edits that disagree with each other. Three of the five recorded conflicts of that kind were caught by its own review step. Fast, cheap enough, and best on well bounded tasks rather than open ended ones.
