A case study inside a real company migrating 12 features of varying complexity from a corporate ERP written in Visual Basic 6, using one version of the Claude Code agent, evaluating both effectiveness and efficiency (arXiv 2608.28972). Legacy modernization is the use case most often asserted and least often measured, so a named-stack, named-agent, feature-count study is worth more to me than another SWE-bench delta. Pair it with DEPBENCH's 51.2% on breaking dependency upgrades for the other half of the maintenance picture.

I've spent real hours tuning the CLAUDE.md in my own repos. Rewriting architecture notes. Adding conventions. Trimming when it got long. So this one stung. arXiv 2607.27250 ran a two-agent ablation across Claude Code and Codex: 17 real tasks from 3 repositories, 288 gold-test-...
This is the paper of the week. arXiv 2607.28871 introduces BSG-VA, which replays every validation command an agent runs across three code states: the original buggy code (B), the candidate patch (S), and the gold developer fix (G). If a test passes in all three states, it neve...
arXiv 2607.28430 adds asynchronous message-passing to coding-agent harnesses with three primitives: threads, messages, and waiting for mentions, where the wait runs as a background task so an agent stays passively aware of teammates without blocking foreground work. Single Cla...
A paper from Xiao Yu, Baolin Peng, and Ruize Xu makes a claim that seems obvious once stated and is genuinely new as a training methodology: modern agents are inseparable from their inference harnesses, so training them in stripped-down RL sandboxes produces a train/serve mism...
Four stories about things going wrong. Here's one about something working, with actual numbers attached. In an August 7 disclosure covered by TechCrunch, Airbnb said AI now writes 60% of its new code, that concept-to-launch time on key initiatives has dropped by as much as 60%...
This one rearranged my week. An essay published August 4 walks through Databricks' independent benchmark of coding harnesses against its own multi-million-line codebase. Pi, a harness with four built-in tools and a system prompt under 1,000 tokens, paired with Opus 4.8 at xhig...
