Common uses are the loading of screen contents, video/audio files, the submission of a form, or a software update.

Used when the time to complete is known. **Indeterminate:** When an unspecified amount of time is found. Used when the time to complete ISN'T known, or it isn't important to show the length of time remaining. **Query:** During the time the app is communicating with the backend we show a visual indicator of that process in an animated dashed progress bar. **Note:** As we know more about a process (loading, saving, etc.), the type can change from Indeterminate to Determinate. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://able.bucca.com/core/overview/progressindicator/progressbar.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
