UserSWE evaluates repository-coding agents in conversations where simulated users reveal bounded information over turns and tests run after each response. Its changing user personas are calibrated from developer sessions. Among 11 agents, Claude Fable 5.1 led at one turn with 31.9%, while Claude Opus 5 had the highest Length-Discounted Pass Rate (LDPR), 0.640; rankings varied by turn budget in UserSWE.
