API開発

Builds and manages stateful AI agents using the OpenAI Assistants API v2 for legacy application maintenance and complex RAG workflows.

This skill provides specialized knowledge for implementing and maintaining OpenAI Assistants API v2 workflows, encompassing stateful threads, high-scale file search, and sandboxed code execution. While the API is scheduled for sunset in August 2026, this skill remains critical for developers managing existing production environments, troubleshooting persistent run errors, or orchestrating migrations to the newer Responses API. It offers comprehensive implementation patterns for Code Interpreter, File Search (up to 10,000 files), and asynchronous run polling.
