OpenAI Responses API Integration

About

This skill empowers developers to transition from stateless Chat Completions to the stateful OpenAI Responses API, enabling the creation of advanced AI agents. It provides standardized patterns for managing persistent conversation IDs, leveraging server-side tools like Code Interpreter and File Search, and integrating with the Model Context Protocol (MCP). By preserving the model's reasoning notebook across turns, it helps users achieve better multi-turn performance, improved cache efficiency, and seamless background processing for complex, long-running tasks.

Key Features

• Reasoning preservation across turns for 5% better multi-turn performance
• 91 GitHub stars
• Stateful conversation management via persistent Conversation IDs
• Server-side tool integration for Code Interpreter, File Search, and Web Search
• Support for polymorphic outputs and background processing modes
• Simplified migration patterns from legacy Chat Completions to Responses API

Use Cases

• Building agentic AI applications that require long-term reasoning and state management
• Optimizing API costs through 40-80% better cache utilization on multi-turn interactions
• Implementing high-performance RAG workflows using server-side File Search
