They can be assigned to individual users, allowing you to delegate tasks across the system so you can account for all work done in each case and ensure everything is properly completed. ### Activities The "Activities" tab covers both time and expense entries. Time entries allow users to record the time they have spent working on a case, whilst expense entries allow them to account for one-off expenses incurred. These are both used in the billing functionality in order to account for the total hours worked and any one-off expenses. This chapter will detail both of these functions and their use within AgileCase. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.agilecase.com/user-documentation/tasks-and-activities.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.
