neuroarxiv Is a Skill Whose Whole Job Is Making Claude Check arXiv Prior Art Before It Invents an Architecture

UditAkhourii/neuroarxiv (279 stars, 30 forks, created 2026-08-05) bills itself as 'a skill to kill from-scratch coding — Claude checks real arXiv prior art before it designs a new architecture.' It hooks the arXiv API into the planning step so a model proposing a novel reasoning or model architecture is forced to retrieve and cite existing work first. It fits a broader pattern visible across this week's trending skills — ponytail, HERO-Anti-OverDefense, gauntlet-loop — where the fastest-growing agent tooling isn't adding capability but constraining it, on the premise that the expensive failure mode of a capable coding agent is confident overbuilding rather than inability.
