Problem or use case

I want to be able to upload pdfs for now I can only upload images

Proposed solution

We just need to have the same behavior than uploading a picture same UX

Why this matters

because I want to upload PDFs when I need to so the coding agent can read

Smallest useful scope

upload a pdf file that can be read but the coding agent like it does with images

I think any of the common file types could be supported. I tried to upload log/txt file to agent for inspection, but it was not possible.

[soufDev]

that's actually a good point I did not try any other files, but yeah we should have them all supported

@juliusmarminge do we have any limitation ? I did not check the codebase yet

Implemented in #8236 with server support from #8235. The composer now accepts PDFs, text files, ZIPs, and other files that the agent can read. Closing this request as completed.
