Mention Another Project
Hand your agent the context of any project, or of a whole sidebar group of projects, from the Projects tab of the Agent Input @ picker, without leaving the terminal you are in. The tab mirrors your sidebar's groups and nesting, so no workspace is needed, and a workspace you belong to still mentions all of its projects in one row.

Why You Need This
How this feature boosts your daily productivity
When the bug is in the API but you are working in the web app, the usual fix is copy-paste: open the other project, find the file, paste it in, and hope you grabbed enough. Mentioning the other project instead gives the agent that project's real context by name: its root folder, the group it sits in, and the AI terminals already open in it. Mentioning one other project also points @ file search at that project's folder, so your file mentions cross the repo boundary rather than stopping at it. When the change spans a product, pick its sidebar group and every project under it, nested groups included, goes along in one mention, worked out again when you press Send, with a plain line telling you if the list had to be cut short.
How It Works
Get started in 4 simple steps
Type @ in Agent Input
The picker opens with tabs for Files, Terminals, Agents, Projects and Templates. Tab and Shift+Tab jump between the tabs that have results.
Open the Projects tab
Your projects are listed the way the sidebar lists them, with groups and nested groups in the same order. No workspace is needed.
Pick a project or a whole group
@Backend mentions one project. A group row mentions every project under it, nested groups included. A workspace you belong to leads the list as one row.
Send with the context attached
Each project reaches the agent with its root folder, its group and its open AI terminals. Mentioning one other project also points @ file search at its folder.

How it compares
To give an agent context from another repo, people paste files into the prompt or add the other folder to the agent's workspace.

Cursor indexes every folder in a multi-root workspace, and an agent session can target a saved workspace of several folders.

Copilot Chat works across the folders of a VS Code multi-root workspace once you add the other repository to it.
