OpenSIN SDK

The @opensin/sdk (TypeScript) and opensin-ouroboros (Python) packages provide the core building blocks for the OpenSIN-AI ecosystem.

Vision

The SDK is designed to be Engine-Agnostic. It provides a high-level orchestration layer that can swap between the TypeScript Runtime (Standard) and the Rust Engine (High-Performance) seamlessly.

Key Packages

Package	Language	Role
@opensin/sdk	TypeScript	Primary orchestration and plugin layer
@opensin/agent-sdk	TypeScript	Specialized tools for building A2A agents
opensin-ouroboros	Python	Data processing and Python-based worker logic

Installation

# Node.js / Bun
bun add @opensin/sdk

# Python
pip install opensin-ouroboros

Core Modules

⚡ Agent Loop

The heart of every agent. Handles the ReAct cycle, token counting, and tool execution.

🛠️ Tool System

A unified interface for local (MCP) and remote (A2A) tools.

🧠 Memory & Context

Advanced context pruning and persistent memory storage.

The 2026 Sovereign Standard

Every SDK interaction follows the A2A-First Mandate:

• Never hardcode API keys; use the Passwordmanager hooks.
• Never use direct LLM calls; use the opencode run abstraction.
• Always provide Evidence-First logs for debugging.
