I'd be interested to see results with Opus 4.6 or 4.5
Also, I bet the quality of these docs vary widely across both human and AI generated ones. Good Agents.md files should have progressive disclosure so only the items required by the task are pulled in (e.g. for DB schema related topics, see such and such a file).
Then there's the choice of pulling things into Agents.md vs skills which the article doesn't explore.
I do feel for the authors, since the article already feels old. The models and tooling around them are changing very quickly.
