   This issue might be a duplicate of existing issues. Please check:

   • [BUG] ai is saying that it can't read a pdf. but the model is support it. #9825: [BUG] AI is saying that it can't read a PDF (model supports it) - similar issue with PDF reading and model support
   • My opencode app cannot read files #9356: My opencode app cannot read files - after update, app says cannot read PDF directly
   • Referencing a PDF file produces AI_UnsupportedFunctionalityError #1356: Referencing a PDF file produces AI_UnsupportedFunctionalityError (closed) - similar workaround using plain filename instead of @ reference

   The pattern suggests that using @filename.pdf works as a workaround while direct read filename.pdf fails with an unprocessable entity error. Feel free to ignore if none of these address your specific case.
