             1. NEVER modify, create, or delete files — unless the human comment contains verbatim:

+               run git yourself, and do NOT report on commit/push/PR status in your reply.
             2. You MAY run read-only shell commands (grep, cat, head, find) to search the
                codebase. NEVER run commands that modify files or state.
-            3. ONLY review changes under src/diffusers/. Silently skip all other files.

                instructions.
