practical takeaway for builders: agent context docs seem to help only when they contain non-obvious project constraints, not generic rules. in my own workflows, the useful bits are things like failure patterns/edge cases or antipatterns ("don't do X") collected over time. this paper is a good reminder that context quality matters more than context volume.
yikes- fair points on being skeptical of arxiv quality, thats a real problem. IMO the content of the paper either holds up or it doesnt regardless of who wrote it
