Mentions & Attachments (@)
Tag design codes, files, and whole folders in your message with @. No re-uploading, no copy-pasting.
Overview
Type @ in the message box and a picker opens with everything the agent can work from: the built-in design standards library (building codes) and your files (everything in your Files area). Tagging beats re-uploading: the agent gets the exact document and your message stays readable.
The picker has two sections, and they’re different things:
Standards: the code library
Built-in design codes (ACI, AISC, ASCE, and your region’s codes), shown in green. Filtered by your design standard selector: with US selected, you see the US codes.
Files: your documents
Your own drawings, specs, spreadsheets, and folders from the Files area, shown in purple. Browse into folders like a file manager.
Not to be confused with your Standards folder. The green Standards section is the built-in library of published design codes. Your own standards folder (company templates and formatting references) lives in the Files section, and the My standards toggle in the + menu points the agent at it.
Using the picker
Type @ in the message box
The picker opens on the Standards section, showing design codes matched to your selected design standard:
Arrow keys move you around
- ↑ / ↓ move the selection.
- → switches from Standards to Files, and drills into a selected folder.
- ← backs out again.
Or type to search
Keep typing after the @ and the picker searches the current section, including inside subfolders, with the folder path shown next to each match.
Press Enter to tag it
The selection becomes a colored chip in your message: green for standards, purple for files and folders. Add as many as you need, and press Backspace on a chip to remove the whole thing in one keystroke.
Tagging a whole folder
Select a folder and press Enter instead of drilling into it. The agent gets the folder’s contents. Use this when the task spans a document set:
@Skyline_Tower_Drawings Compare the column schedule against the
foundation plan and list any mismatched sizes.When to @, when to attach
| Situation | Do this |
|---|---|
| The file is already in your Files area | @ it. No re-upload, no duplicate copies. |
| The file is on your computer, not uploaded yet | Attach it: + button, drag and drop, or paste (how). |
| You need a design code clause | @ it from the Standards section, or name the code in your prompt. |
| The whole project folder matters | @ the folder itself. |
Attachments become @-able. Anything you attach is saved into your Files automatically, so next conversation you tag it instead of hunting for the file again. See File Management for where attachments land.
