You need to distinguish between the model and the agent. claude.md skills rules are handled by the agent.
The model is similar to the brain, and the agent is similar to the hands. The brain directs the hands to take claude.md skills rules and other resources to feed the brain.

where did you get the "are no longer compatible" part? we moved from opus 4 to opus 5 without changing anything and no specific conflicts. used fable for a while, also did not have to change anything. I read some advice on the anthropic website that opus 5 doesn't require as many examples as before, but this was a recommendation how to make things shorter, not a backwards compatibility issue.

These models don't take claude.md, Claude Code does, and claude.md still get fed to these models if you're using Claude Code.
That said, prompting on opus 5 needs new technique: https://platform.claude.com/docs/en/build-with-claude/prompt...
