Common questions
Is a tool name an error?
Usually the name is a label for a step, not the failure itself. Read the next message and look for a file or a separate error. The file_gen guide explains what the prefix can and cannot tell you.
Does file_gen:generate_pdf prove that my PDF exists?
No. Open the PDF attachment or link and check its contents. If none appears, the PDF tool-name guide gives the next checks.
Where should I start if the file link fails?
Use the generated_file_link guide to separate a missing attachment from a link that exists but fails. If ChatGPT says Download failed or File Not Found, use the ChatGPT download guide.
