> For the complete documentation index, see [llms.txt](https://mediamarkup.gitbook.io/docs/llms.txt). Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://mediamarkup.gitbook.io/docs/introduction/the-magic-pen.md). # The Magic Pen The Magic Pen allows ad-hoc markup within an approval for real-time collaboration.\ These annotations are not saved, and primarily used within the session or real-time discussion.\ \ Any user viewing the the same approval on the same page (and in the same approval group) can see and draw annotation using the magic pen. Any user can also delete all these magic pen annotations.\ \ This is useful for real-time discussions, where reviews and approvals can easily share their views by marking up / drawing on the document or image without having to add save an annotation. --- # 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://mediamarkup.gitbook.io/docs/introduction/the-magic-pen.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.
