[Upload Agent](/user/uploading-and-downloading-files/upload-agent.md) is a fast, concurrent upload client that can resume interrupted uploads and upload up to 1000 files at a time. [Download Agent](/user/uploading-and-downloading-files/download-agent.md) is designed for long-running downloads, verifying file integrity in real time and supporting post-download re-validation. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://documentation.dnanexus.com/user/uploading-and-downloading-files/batch.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
