Attachments and output files

Two file flows matter in daily work: files you give to an agent, and files the agent gives you.

Attach images to a prompt

Attach an image in any of three ways:

• Paste an image into the composer.
• Drag an image file onto the composer.
• Pick a file with the attachment control.

Attached images travel to the host device, and the agent receives them with your prompt. You can stash an attachment to reuse it in a later prompt in the same session. Select a thumbnail in the transcript to open the full image in a lightbox.

Open files the agent made

Agents produce files: code, documents, spreadsheets, images, HTML previews. Open them from file links in replies, from tool rows in the transcript, and from the file tree.

Actions available on an output file:

• Open in default app.
• Show in folder.
• Open in browser. For HTML and PDF files, on macOS. The page opens in a sandboxed browser tab.
• Copy path.

Spreadsheets and data files

Excel workbooks and CSV or TSV files open as a read-only table inside Admiral:

• Sheet tabs across the top, column letters on the pinned header row.
• The table shows up to 5,000 rows and 200 columns; a banner says when a file is truncated, and the owning device parses the full file.
• Use Open in default app for the real spreadsheet app.

Remote files

Sessions hosted on another device still show their files. When you open a remote file, Admiral copies it to a local cache so it opens at full speed. Very large remote files refuse to open locally; open them on the host device.

Next steps

• Steer and queue: attachments queue differently. Here is why.
• Review changes: the diff view for code changes.
