**Drop-in replacement for `@anthropic-ai/claude-agent-sdk` — same API, multiple providers.**

[Getting Started](#getting-started) · [Features](#features) · [Providers](#supported-providers) · [API Reference](#api-reference) · [Examples](#examples)

import { query, tool, createSdkMcpServer } from "one-agent-sdk";

// Same API as @anthropic-ai/claude-agent-sdk — swap provider with one option
const conversation = query({
  prompt: "What's the weather?",
  options: { provider: "codex" }, // or "openai", "anthropic", "openrouter", ...
});

The Problem

`@anthropic-ai/claude-agent-sdk` has a great API — but it only works with Claude Code. If you want to use Codex or Kimi, you have to learn a completely different SDK.

The Solution

One Agent SDK is a drop-in replacement for `@anthropic-ai/claude-agent-sdk` that routes to any backend. Same `query()`, `tool()`, `createSdkMcpServer()` — just pass `options.provider` to switch:

  const conversation = query({
    prompt: "Analyze this code",
-   options: { systemPrompt: "You are helpful." },
+   optio
