A web app that spawns four specialist agents in parallel, streams their responses to the browser in real time via SSE, then feeds their findings into a synthesizer agent that produces a unified decision brief.

Getting started

Install dependencies:

bun install
bun run build:sdk

Set an API key:

export CLINE_API_KEY="cline_..."

Run:

bun dev

Open http://localhost:3456 in your browser, enter a mission, and watch the agents work.

What it does

You enter a mission in the browser
The server spawns four Agent instances in parallel via Promise.all:
- Architect (system design)
- Security Analyst (audit)
- Pragmatist (product)
- Skeptic (red team)
Each agent streams assistant-text-delta events to the browser via SSE, rendered in its own card
Once all specialists finish, a synthesizer agent combines their findings into a unified decision brief, also streamed live

Concepts demonstrated

Running multiple Agent instances concurrently with Promise.all
Per-agent subscribe() for independent event streams
Server-Sent Events (SSE) to stream agent output to a browser
Agent composition: feeding one agent's output as input to another
Inline HTML frontend served from the same Node.js server (single file, no build step)
