@-mentions to point to a specific resource.
Attach context with @
Type @ to bring up the Select context item picker. It attaches things from your environment to the message, each appearing as a chip so the agents act on exactly what you mean.
Devices and integrations
A host from your inventory or a connected system — the picker groups them as
Devices and Integrations.
Folders, plans and files
A folder of assets with its governance rules, the working plan in progress,
or a file you attach for analysis.

@ is not an agent selector. To send a request to a particular
specialist, name them in the message — “Perseus, list the running processes
on…”. With no name, Centurion routes it for you.
Start from a Prompt Template
If you’re not sure how to phrase a request, pick a predefined template to get a well-formed starting prompt you can edit before sending.Audit
Kick off an assessment of a device, integration, or your environment.
Configure
Change or harden the settings of a connected asset.
Investigate
Look into an alert, indicator, or suspicious behavior.
Report
Turn an analysis into a shareable document.

Pull in External Documents
Type/ to run a slash command. Slash commands let you pull a document straight into the conversation from SharePoint or Google Drive — for example a /read-document command backed by your personal connectors — so the agents can work from a spec, policy, or spreadsheet you already have.
Attach Files and Images
Attach files directly to a message when you want the agents to analyze something you have on hand — documents (PDF, TXT), images (PNG, JPG), and audio. The content becomes part of the request context.Work Faster in the Input Box
Queue follow-ups
While an agent is working, line up to three more messages — they send
automatically as the current one finishes.
Recall messages
Press
Alt+↑ and Alt+↓ (Cmd on a Mac) to cycle through messages you sent earlier and
reuse them.Autocomplete words
Press
Tab to accept context-aware suggestions for commands and asset names
as you type.Track usage
A usage indicator shows how much of the conversation’s large context window
(on the order of one million tokens) you’ve used.
Act on a Response
Every agent message carries its own actions:- Copy the message text.
- Rate it with thumbs up or thumbs down to send feedback that improves the agents.
- Send to Clipboard to collect a table, JSON, or code block in the Clipboard tab for editing and reuse.
Manage Your Conversations
Start a New Chat to pivot to a fresh topic, Favorite a conversation to pin it, and open Chat History to return to any past thread.As the agents work, results open as tabs in the Workspace panel on the right,
so you never lose your place. Watch agents reason and act in Live reasoning &
operational panels.
