What
When writing to a project would put it over its maximum size, the write is refused and nothing in the project changes. The refusal tells Claude this, and tells it not to delete documents in order to retry the write.
Why
This is guidance for Claude in a new kind of failure. It stops Claude from removing your project documents just to squeeze a new one in.
