Study: AI Coding Agents Fail Coordination at Scale
rohanpaul_ai · x · 2026-08-23
A study of 1,902 AI coding agent runs found that splitting tasks across more agents scatters decisions into gaps between them, causing failures. A task passed 9/10 times with 2 and 4 agents but failed all 10 runs with 8 agents due to a rounding rule falling between two agents. Merely prompting a 'coordinator' builds no structure. The paper advises checking which decisions move into the gaps before adding an agent.
