Overview
@mentions let you scope a prompt to specific project knowledge without manually rebuilding scope every time.
When you mention an item, Chief adds it to the prompt’s effective knowledge scope for that turn. This helps you:
focus answers on the right sources
reduce irrelevant context
reuse known scopes like Labels and Collections
move faster in research and reporting workflows
In Chief, @mentions integrate directly with the same scope model used by Powering this chat.
ℹ️ By default, Chief uses all your files in your Project regardless if you @mention specific items. Learn more here: How to manage scope
What you can @mention
In your prompt, you can @mention:
Files (assets)
Labels
Collections
Concepts
Agents
Skills
Personas
How to @mention in a prompt
Click in the prompt bar.
As you’re typing your prompt, type
@.Search and select the item you want to mention.
Send your message.
Chief uses those mentions as scoped inputs for the response.
How @mentions affect scope
After adding mentions:
The Powering this chat summary reflects the active scoped sources.
Mentioned entities merge with existing scoped selections instead of replacing everything by default.
If you explicitly use full project/library scope chips in the prompt, Chief can prioritize that broader project scope for the turn.
If you exclude certain items, Chief shows you which items are powering the conversation
Tips & Best Practices
Use @mentions to stay precise: The more targeted your prompt, the better your results.
Mention multiple items when comparing: Great for side-by-side analysis.
Watch for name clarity: Give your assets and concepts clear titles so they’re easy to find in the dropdown.
