JetBrains Research argues coding-agent benchmarks should reflect real users' multi-turn mixed task flows rather than single-turn static issues. Analyzing 4,782 real sessions, they built SWE-TaskFlow to split SWE-Bench Pro tasks into multiple turns with code checkpoints, finding that on 700 tasks agent costs roughly doubled without stable success rate improvements, recommending benchmark customization based on actual user request distributions.

    • Current benchmarks like SWE-Bench Pro handle only single-turn detailed issues, whereas real user sessions show feature development and bug fixes account for less than half of requests, with frequent switching among questioning, planning, review, and editing tasks.
    • JetBrains' SWE-TaskFlow framework simulates real interactions by splitting tasks into multiple turns and adding verifiable code checkpoints, but testing on 700 tasks revealed approximately doubled agent computational costs without stable success rate improvements.
    • The study emphasizes measuring actual user task distributions before evaluating coding agents, advocating for customizing benchmark conversation structures to match real-world patterns rather than applying generic static benchmarks directly.
