For AI Agents

Hand your agent this brief or the ReUI MCP, not a screenshot. Installs with a ReUI Pro or Ultimate license.

Best for: A reply's evidence with no run controls: numbered sources with publisher logos, repo files with line counts and a confidence badge

When to use

  • A live step feed of one agent run that the person who started it can approve, pause or stop
  • The research trail behind an answer: the search query, numbered sources, repo files and confidence
  • A record of what a run touched and settled: MCP calls per server, refused scopes and failed items

When not to use

  • A plain vertical sequence of steps or events with no search, sources or answer: use the Timeline component
  • A docs help sidebar that reads knowledge base articles before it writes an answer: use the Docs Support Assistant block
  • Operator pages across many runs: a run queue, an approval inbox or tool access settings: use the Agents blocks
  • The conversation around the run: the message thread, the prompt composer and the replies: use the AI Chat blocks
  • A dated history of what people did, such as activity feeds, milestones or release notes: use the Timeline blocks

Agent notes

  • Replace RESEARCH, SOURCES, CHECKED and ANSWER; each source logo is a brand mark from @/components/ui/svgs and each dwellMs sets the pace
  • ANSWER.confidence always renders in a success-light badge whatever its text; map your confidence levels to badge variants
  • A source title and Open source only fire a toast with the brand, so url is copied but never opened; Open file is a toast as well
  • Each page.tsx pads a top aligned min-h-svh wrapper around AgentActivity, whose root caps at max-w-xl or max-w-2xl; drop the wrapper in your layout
  • Each run is replayed from the block's data file on setTimeout timers; drive the same state from your agent's events instead
  • Each block calls toast from sonner but mounts no toaster, so those messages stay hidden until your layout renders one

Frequently Asked Questions

When should I use the Research Timeline block?

For the conversation around the run: the message thread, the prompt composer and the replies, use the AI Chat blocks. For a dated history of what people did, such as activity feeds, milestones or release notes, use the Timeline blocks.

What is the Research Timeline block built with?

Research Timeline uses Badge, Button, Card, Item, Marker, Skeleton, Spinner, Timeline, Tooltip. Installing the block through the ReUI registry pulls those dependencies in for you.

Can I restyle the Research Timeline block?

How should I use Shadcn agent activity blocks in a real project?

Treat them as structured starting points. Keep the layout, hierarchy, and interaction ideas that work, then replace placeholder content, data wiring, and business logic with your own product requirements.
