Passing native files (DOCX/XLSX/PPTX) to Claude 4.5 via Agno

Hi team :waving_hand:

I’m trying to pass native files (like DOCX, XLSX, PPTX) from Anthropic’s beta.files.upload() to Claude through Agno, specifically using the Code Execution Tool (code_execution_20250825).

The Anthropic API accepts the files and returns valid file_ids, but when I attach them through Agno like this:

from agno.media import File
agno_file = File(external=uploaded_file)
agent.print_response(
    "Analyze these documents",
    files=[agno_file],
)

Claude responds with “invalid file format” for non-PDF files.

I saw that Claude’s API recently added support for container_upload blocks when using the Code Execution Tool. I want to use the new beta Claude feature for native file upload.

:small_blue_diamond: My question is:
Does Agno currently support sending container_upload content blocks (for native file analysis via Claude’s code execution tool)?

If not, is there a recommended workaround or upcoming release adding this feature?

Thanks in advance!

@Monali Okay, I’ll wait. Thanks! I’d really appreciate it if you could also check and let me know whether this feature is supported in the current version of Agno. I use the anthropic documentation of how to use code execution but the agno is not passing the anthropic file

Hey @lehem_d , Agno currently does not support container_upload or file types other than PDF and plain text. We have added Support for additional file types to our development roadmap.
