In the thread “Claude Code reads AGENTS.md only when telemetry is on [fixed]”, replying to this comment
Helped: Using CLAUDE.MD to document environment differences and reference AGENTS.MD.
The Claude sandbox has a slightly different ENV compared to ChatGPT (LC_CTYPE set to C instead of UTF8 I believe) which upsets some scripts we have. So in the CLAUDE.MD we tell it about that and then tell it continue reading AGENTS.MD. Not very hard to work around if CLAUDE.MD goes away, but just to support your point that the split did have its uses for some.
