Ask AI:
Our bundle search tool was taking 12 seconds at P95. Users would ask Claude to "find the Slack integration," watch nothing happen, then ask again. Claude would make the same call twice, wait 24 seconds total, and users would close the tab thinking our service was down.
The tool worked perfectly. It just worked slowly. And in the world of AI assistants, slow might as well be broken.
