SWE Refactor Bench: Can Coding Agents Complete a Long-Horizon, Whole-Repository Stack Migration?
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- Researchers released SWE Refactor Bench, a benchmark testing whether AI coding agents can autonomously perform whole-repository stack migrations across 20 real tasks.
- Why it matters
- Matters for teams evaluating coding agents for technical debt work, especially large-scale framework or language migrations in production systems.
- Watch out
- Only 5.4% of 520 runs passed all evaluation stages. Agents often skip migrations entirely or break behavior. Results vary drastically by migration type.
