Start building

npm install @deuz-sdk/core

Set ANTHROPIC_API_KEY, then run your first agent:

import { runAgent } from '@deuz-sdk/core/agent';
import { createAnthropic } from '@deuz-sdk/core/anthropic';

const anthropic = createAnthropic({ apiKey: process.env.ANTHROPIC_API_KEY });

const result = await runAgent({
  model: anthropic('claude-opus-4-8'),
  prompt: 'Explain how rainbows form in three sentences.',
  maxSteps: 4,
});

if (result.status === 'completed') console.log(result.output);

Use Node.js 22+, or an edge runtime with Web APIs. Node integrations have separate imports.

What ships

• Models — multiple providers, streaming, structured output, and tool calls.
• Agents — typed results, verification, approvals, and resumable runs.
• Swarms — task dependencies, bounded parallel work, reducers, and SQLite persistence.
• Context — memory, retrieval, compaction, and MCP tools.
• Control — shared execution policies, budget accounting, traces, and optional React bindings.

Core has zero required runtime dependencies; integrations use optional peers. In 2.1, each swarm run has one executor, and uncertain external effects require reconciliation before retry.
