What problem does it solve? Developers building with OpenAI APIs often rely on outdated or unofficial information when choosing models, migrating integrations, or updating prompts. This Skill grounds every answer in current official OpenAI developer documentation with citations, so guidance on models, APIs, and upgrades stays accurate. ## Core Features & Use Cases - Official Docs Lookup: Searches and fetches pages from the developers.openai.com MCP server, quoting exact sections with concise citations. - Model Selection & Migration: Resolves the latest recommended model, classifies upgrades as model-string-only, light prompt rewrite, or blocked, and keeps changes narrow and behavior-preserving. - Prompt-Upgrade Guidance: Applies bundled prompting and upgrade guides (with remote freshness checks) to adapt prompts for newer models without scope creep. - Use Case: A user asks to migrate a GPT-4o assistant to the latest model. The Skill fetches the current latest-model guide, recommends the target model string and reasoning effort, and suggests only the minimal prompt blocks needed. ## Quick Start Ask the assistant to look up the latest OpenAI model guidance and recommend how to upgrade your existing API integration with citations from official docs.
