SummaryA research paper tests whether LLMs can maintain exact intermediate state across long sequences of dependent tool calls by having a model compute MD5 step by step across 196 calls and 64 rounds. Using gpt-oss-120b, it finds that keeping the model's own reasoning in context and voting over a thinking-enabled worker enables correct end-to-end execution.
Why it mattersIsolates state-tracking from instruction following using a cryptographic ground truth, and surfaces two concrete fixes—context-resident reasoning and worker voting—for long-horizon agent failures.
