Original GitHub issue: https://github.com/Mintplex-Labs/anything-llm/issues/2451

How are you running AnythingLLM?

All versions

What happened?

If I request that the agent create a PDF (locally or hosted) the PDF when downloaded will not open ... Adobe reader reports it as damaged or corrupt. Tried on multiple systems. I don't get any errors.

Are there known steps to reproduce?

Happens with every creation and export

Further info...What appears to be happening is that the chat text is exported as a PDF file but it is just a plain text file. Export as txt instruction works as it sends the same data but gives it a .txt filename vs. pdf. I used the syntax from the DOCs to ensure I was instructing it correctly @agent can save this information as a PDF on my desktop folder?

This is not a skill that we even offer. The only agent skill built-in we offer is text files. You cannot just change the extensions of a text file into .pdf and have that work - they are two totally different file types.

If you specifically require PDF generation you will need to make a skill for that with custom agent skills. The LLM will simply hallucinate the PDF generation using the text doc skill and tell you it works - which is what is occurring here.

If thats the case you might want to update your documentation as in your Usage Documentation you use PDF as your example.... I only tried is because you provide it as the example in your documentation. If you just offer txt use that as the example....
