Build your first agent stack

The DeesseJS agent stack wires three things together: a model provider, a tool registry, and a streaming endpoint that surfaces the agent's reasoning in real time.

1. Install the SDK

pnpm add @deessejs/agents

2. Compose an agent

import { Agent } from "@deessejs/agents"

const agent = new Agent({
  model: "claude-sonnet",
  tools: [searchDocs, runQuery, deployPreview],
})

3. Stream the response

for await (const chunk of agent.stream("Deploy the staging env")) {
  process.stdout.write(chunk.text)
}

What's next

• Use the Next.js RAG template — wire embeddings and a vector store.
• Add observability — capture traces from the streaming endpoint.
