# sphinx-doc__sphinx-8801
# Loki Mode Multi-Agent Patch
# Attempts: 1

I need to look for a real sphinx repository. This appears to be a different project. Let me generate the patch based on my knowledge of the Sphinx codebase for the 3.x branch where this bug exists:

Actually, let me provide a more accurate and complete patch based on the specific issue. The issue is that when `get_doc()` is called for an annotation-only inherited member, it doesn't look up the `#:` comment docstring from the parent class. Let me create a precise fix:
