  Migrate existing AI agent projects (LangChain, LangGraph, OpenAI Agents SDK,
  Claude Agent SDK, CrewAI) to EdgeOne Makers platform conventions.
  Use when the user wants to adapt a standard agent project to run on EdgeOne Makers,
  convert Express/Next.js API routes to Makers handlers, or add platform capabilities
  (context.tools, context.sandbox, context.store).
  Do NOT trigger for new agent projects (use makers-agents instead).
pathPatterns:
  - agents/**
  - cloud-functions/**

  - pattern: "process\\.env|os\\.environ"
    message: "Migration checklist: replace process.env / os.environ with context.env (TS) or ctx env access (Python)."

EdgeOne Makers Migration Guide

Migrate existing AI agent projects to the **EdgeOne Makers** platform format. Covers structural conversion, API adaptation, and platform capability injection.

⚠️ Migration Checklist (common to all frameworks)

Before starting framework-specific changes, check these global items:

• [ ] Create `edgeone.json` with correct `agents.framework` and `buildCommand`/`outputDirectory`
• [ ] Move backend code from Express routes / Next.js API routes into `agents/` directory
• [ ] Replace `process.env` / `os.environ` with `context.env` / `ctx.env`
• [ ] Replace `req.headers.get('x')` with `context.request.headers['x']` (Node) or plain dict access (Python)
• [ ] Replace `await req.json()` with `context.request.body` (already parsed)
• [ ] Replace direct model API calls (OpenAI, Anthropic) with `AI_GATEWAY_*` env vars
• [ ] Add SSE streaming for AI endpoints (replace `res.json()` / `return {"data": ...}`)
• [ ] Add `makers-conversation-id` header to frontend fetch calls
• [ ] Wire platform tools through `context.tools` instead of custom tool implementations
• [ ] Wire conversation history through `context.store` instead of in-memory or custom DB
• [ ] If using web_search, set `WSA_API_KEY` env var and use `context.tools.get("web_search")`
• [ ] Set up `edgeone makers dev` for local development

§1. Standard API Route → Makers Handler

This is the most common migration pattern. Applies to Express/Next.js API routes, plain HTTP handlers, etc.

Node (Express/Next.js → Makers)

// ❌ Before: Next.js API route (app/api/chat/route.ts)
export async function POST(req: Request) {
  const body = await req.json();
  const headers = req.headers;
  const apiKey = process.env.OPENAI_API_KEY;
  // ... LLM call ...
  return Response.json({ data: result });
}

// ✅ After: Makers agent handler (agents/chat/index.ts)
export async function onRequest(context: any) {
  const body = context.request.body;               // already parsed
  const conversationId = context.conversation_id;   // auto-injected from header
  const env = context.env;                          // context.env, never process.env
  // ... LLM call via AI_GATEWAY_* ...
  return new Response(JSON.stringify({ data: result }), {
    headers: { 'Content-Type': 'application/json' },
  });
}

Python (Flask/FastAPI → Makers)

# ❌ Before: Flask route
@app.route('/chat', methods=['POST'])
def chat():
    body = request.get_json()
    api_key = os.environ.get('OPENAI_API_KEY')
    # ... LLM call ...
    return jsonify({'data': result})

# ✅ After: Makers agent handler (agents/chat/index.py)
async def handler(ctx):
    body = ctx.request.body
    conversation_id = ctx.conversation_id
    api_key = ctx.env.get("AI_GATEWAY_API_KEY")
    # ... LLM call via AI_GATEWAY_* ...
    return {"data": result}

§2. CrewAI (Python)

Key changes

| Before | After | |--------|-------| | `os.environ.get("OPENAI_API_KEY")` | `ctx.env.get("AI_GATEWAY_API_KEY")` | | `LLM(provider="openai", ...)` — LiteLLM dispatch | `LLM(provider="openai", base_url=ctx.env["AI_GATEWAY_BASE_URL"], ...)` — bypass LiteLLM | | `memory=True` on Crew | `memory=False` + use `ctx.store` | | `verbose=True` | `verbose=False` (events go through `crewai_event_bus`) | | `crew.kickoff()` (blocking) | `await asyncio.to_thread(crew.kickoff)` | | Custom search tools | Use `ctx.tools.to_crewai_tools(BaseTool)` | | Flask/FastAPI handler | `async def handler(ctx):` → `ctx.utils.stream_sse(gen())` |

edgeone.json

{
  "buildCommand": "",
  "outputDirectory": "",
  "agents": {
    "framework": "crewai"
  }
}

Requirements

crewai>=1.14.5
openai>=1.50.0

Migration steps

1. Replace Flask/FastAPI entry with `async def handler(ctx):` 2. Read env from `ctx.env`, never `os.environ` 3. Use `LLM(provider="openai", api_key=ctx.env["AI_GATEWAY_API_KEY"], base_url=ctx.env["AI_GATEWAY_BASE_URL"])` 4. Set `Crew(memory=False, verbose=False)` 5. Wrap `crew.kickoff()` in `asyncio.to_thread()` 6. Replace custom tools with `ctx.tools.to_crewai_tools(BaseTool)` 7. Return SSE via `ctx.utils.stream_sse(gen())`

> See [makers-agents/references/python-frameworks/crewai.md](../makers-agents/references/python-frameworks/crewai.md) for the complete pattern. > Detailed before/after: [references/crewai-to-makers.md](references/crewai-to-makers.md)

§3. LangGraph / DeepAgents (Node + Python)

Key changes

| Before | After | |--------|-------| | Direct model creation (`new ChatOpenAI(...)`) | Use `AI_GATEWAY_*` for apiKey/baseURL | | `MemorySaver` (in-memory checkp
