The SendUserFile tool now accepts a display parameter to control how files are presented to the user:
render— opens the file inline in the side panel (for HTML, SVG, Mermaid, images, PDFs, and other viewable content).attach— shows a download card only (for source code, spreadsheets, documents intended for other apps).- Omit to let the client decide based on file type (existing behavior).
Evidence
Updated tool description (search for "Set \display\ to choose how the file is presented")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
