Bilevel Coordinated Reflection: A Game-Theoretic Approach to Multi-Agent LLM Systems
Models orchestrator-worker LLM systems as a bilevel coordination game and derives finite-time guarantees for free-form reflection, plus an impossibility result: a gate seeing only the transcript cannot uniformly improve over text-indistinguishable environments, while an environment-grounded gate can. Yields SRMA, a memory-acceptance method that on 500 SWE-bench instances with Kimi resolves 72.2% vs a 70.8% mini-SWE-agent reference.
Why it matters
First unified theoretical account of why transcript-only reflection stalls in multi-agent setups, with a grounded-evaluation gate as the actionable fix. Top paper of the Sep 7 HF Daily batch at 94 upvotes.
