Widgets - unicorn

A widget is a small interactive card that appears inside the chat, in place of a block of text. unicorn has six. Each one shows the same information your agent would otherwise write out, and adds buttons for the obvious next step.

The six widgets

Widget	Appears when you ask for	What it shows	Buttons
Briefs	Your unread briefs	Each brief, read or unread	Mark read, Mark all read, Discuss this
Course	One course	Its buckets and the items in each, with staff posts marked	Open, Break this down, What do staff say about this?
Changes	What changed	Recent change events, newest first	What matters here?
Plan	A weekly or assignment plan	The checklist, with tickable items	Ticking an item saves the plan. Replan the rest
Deadlines	Upcoming deadlines, or a search for items	Items on a timeline by due date	Plan around this
Connections	unicorn’s status	Each source, its last sync and any error	Help me fix a source

A button that says “Discuss this” or “Break this down” does not run anything by itself. It sends a message to your agent, as if you had typed it, and your agent then replies.

Where they appear

Client	Widgets
claude.ai (web)	Yes
Claude desktop	Yes
Claude on mobile	Yes
ChatGPT	Yes
Claude Code	No. You get the text version.
Cowork	Not confirmed. If you see plain text, that is the fallback.
Other MCP clients	Only if the client supports MCP Apps. Otherwise you get the text version.

The text fallback

Every tool result also comes as plain text, and the text has the full content. A client that cannot show a widget shows the text, so nothing is missing. Buttons that need your agent, such as Discuss this, are hidden in a client that cannot send messages from a widget.

What widgets can and cannot do

They change unicorn’s own state only: marking a brief read, or saving a plan when you tick an item.
They never write to Ed, Moodle, Canvas or Gmail.
They load nothing from the internet. Everything a widget shows came from your unicorn.

Ask your agent for the same thing in words, for example “show my unread briefs”, and check that the client is one from the table above. If the plain text shows instead of a card, the client does not support widgets. That is expected and not a fault in unicorn.
