One of 2 test cases the skill fixed. Same model, same prompt, with and without the skill.

Prompt
Our vector index experiences continuous heavy write operations and frequent payload updates, resulting in index fragmentation and recall degradation over time. How should the system architecture address this index degradation lifecycle?
