Files

How the agent hands files to a human — into the chat, into your messenger — and where to pick them up.

Agents produce files — reports, decks, archives, previews — and hand them over with send_file. The file always stays in the run workspace; delivery goes wherever it is convenient for you.

#In the chat

After send_file, a file chip appears under the answer — «📎 preview.png». Clicking it downloads the file from the run workspace. The chip appears the moment the send starts, even if the model's reply forgets to mention the file.

If the agent works with a messenger, the file is delivered there as an attachment: a document in Matrix, a file with a caption in Telegram.

#In messengers

Delivery goes to every connected channel of the recipient that can carry attachments. If no channel is configured, the file stays in the run workspace — and the agent is instructed to mention the path in its reply, which the chat turns into a download link.

#Limits

• Attachment size — up to 50 MB (messenger storage caps).
• The file never leaves the system until delivered: «sent» means «in the run workspace and/or delivered to a channel» — the tool result always shows which.
