Thus, at the most basic level, all you need is a text editor (Notepad, Command Line Interface (CLI), or whatever) to write code. However, there is software that is specifically designed to write code and I highly recommend you find the one that works best for you and your chosen programming language. Text editors designed and specialized to write programming source code are called source code editors. --- # 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://university-west.gitbook.io/programming-paradigms/program-creation-and-design/writing-programs.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.
