Show what your AI agent is actually doing — tool calls, reasoning, cost, approval gates.
by AI Marketplace OS · New publisher
Why this exists
Every AI product ends up rebuilding the same UI: what is the agent doing right now, what did that tool call cost, and how does a human approve the risky step? The chat frameworks (assistant-ui, CopilotKit, AI Elements) render messages — the *agent activity layer* is left to you. This is that layer, finished.
What you get
- **TraceTimeline** — live-updating activity stream; events with the same id update in place, so it reads like a story, not a log
- **ToolCallCard** — running/succeeded/failed states, durations, expandable input/output; failures auto-expand with the error
- **ApprovalGate** — severity-tinted (info/caution/danger) human decision points with optional countdown, collapsing to quiet receipts once decided
- **ReasoningStep** + **CostMeter** — streamed thinking; pinned cumulative spend with model + token detail
- **fromUIMessages** — Vercel AI SDK v5 adapter (structural typing, no dependency on the `ai` package)
Facts an agent should know
- Peer deps: react >= 18 only. ESM. Import `styles.css` once. Client components (use inside a `"use client"` boundary in Next.js App Router).
- Theming via `--amos-*` CSS custom properties; light/dark built in; `prefers-reduced-motion` respected.
- Ships with tests, full TypeScript declarations, AGENTS.md integration brief, and a runnable demo.
