Client-specific metrics reveal hidden AI tool performance gaps

A server-wide average metric for tool usage can obscure critical performance issues specific to certain clients. For instance, a 62% success rate might appear acceptable overall, but it could mask a significantly lower success rate for users on a particular client like Cursor+, while other clients like Claude Desktop or .codex perform well. This averaging hides the need for targeted fixes, such as rephrasing descriptions or adjusting parameter handling for specific client-model interactions. Developers should implement client-specific logging to identify and address these disparities, ensuring a better user experience across all platforms. AI

    <p>Say a tool's first-call success is 62%. What do you change?</p> <p>You can't tell. 62% might be a tool every model finds mildly confusing, in which case the description needs work. Or it might be a tool one client reads perfectly and another reads badly, which is a completely …
