Provider SDK

LLM providers are added via adapter implementations in packages/provider-sdk.

Adapter contract

Provider adapters expose:

• provider definition metadata
• non-stream generation
• optional streaming generation
• tool-call aware response handling

Built-in providers

• ollama
• openai_compatible
• openai
• azure_openai
• gemini (basic)

Add a new provider

1. Implement adapter in packages/provider-sdk/src/providers
2. Register in packages/provider-sdk/src/index.ts
3. Add provider id/type to shared types if needed
4. Add UI fields in node config modal
5. Add tests in workflow engine/provider package
