SWE-Edit: Rethinking Code Editing for Efficient SWE-Agent

Elsie Nallipogu, Jiaxin Pei, Jin Pan, Junjie Hu, Kenan Li, Maoquan Wang, Qirui Jin, Shengyu Fu, Yikai Zhang, Yufan Huang, Yu Kang, Zijian Jin

SWE-Edit splits code editing into a Viewer subagent for on-demand inspection and an Editor subagent for applying changes from plans, freeing the main agent to reason in cleaner context windows.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

On SWE-bench Verified, SWE-Edit improves resolved rate by 2.1% while reducing inference cost by 17.9%.

C2weakest assumption

That separating Viewer and Editor subagents plus adaptive mode selection will not introduce coordination overhead or new failure modes that cancel the reported gains; the abstract provides no ablation on subagent communication cost or error propagation.

C3one line summary

SWE-Edit decomposes agent code editing into specialized subagents and adaptive editing modes, raising resolved rate 2.1% and cutting inference cost 17.9% on SWE-bench Verified while releasing a predictive editing benchmark.
