Field notes, issue 1
Our first weekly issue, one skill test across three hosts, a September Claude Code change worth knowing, and one failure we're still chasing.
Loads checked on Codex only. Other hosts remain not checked.
Dhruva Guptha · Sep 27, 2026Tested this week
One small skill was installed in Codex and Claude Code. Live loading was checked on Codex only.
A change that matters
Claude Code added an AGENTS.md fallback in September 2026. Check the version you use.
An honest failure
A missing reference was not caught by the format checker, and its failed read did not appear in the final answer.
