The ACI doc separately says a baseline without a tuned ACI did much worse in the paper. These may involve different models and baselines, so comparability is unknown and they are not necessarily in conflict.\n\nEvidence strength: LIMITED\n\nTransferability: UNKNOWN\n\nCost effect: UNKNOWN; latency effect: UNKNOWN\n\nRecommended behavior: HYPOTHESIS: do not drop or add ACI features without a measured comparison on the target model.\n\nAnti-pattern: Treating ACI features as either essential or unnecessary without an ablation.\n\nMaterial claims and sources:\n- claim-1: The SWE-agent README states that mini-swe-agent has superseded SWE-agent and matches its performance while being much simpler. [swe-agent-overview; EXTERNAL_EVIDENCE]\n- claim-2: The ACI documentation states that, as shown in the SWE-agent paper, a baseline agent without a well-tuned ACI does much worse than SWE-agent.
