What
rename_session is a request a program driving Claude Code can send to rename a session. When that program has not set up a way to handle renames, Claude Code replies with an error. That error is now built by Claude Code's shared error code instead of by hand. The message still reads "rename_session is not supported in this context (onRenameSession callback not registered)".
Why
Programs that handle this error get it in the same form as other errors, though the exact shape may differ slightly from before.
