What Cursor coverage depends on
Editor-side AI traffic has a different failure mode from a single prompt in a web app. Requests can happen in the background, providers can shift, and the cost can grow while your attention is somewhere else in the coding workflow.
TokenBar is strongest when the editor integration and provider routing are supported. In custom API key or non-standard routing setups, the app may show the underlying provider activity instead of a clean Cursor session, or miss the session entirely.
