Multi-Agent War Room

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

1. You enter a mission in the browser
2. The server spawns four Agent instances in parallel via Promise.all:
   • Architect (system design)
   • Security Analyst (audit)
   • Pragmatist (product)
   • Skeptic (red team)
3. Each agent streams assistant-text-delta events to the browser via SSE, rendered in its own card
4. 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)
