What problem does it solve? Developers building with OpenAI APIs often rely on outdated blog posts or stale training data when choosing models, migrating model strings, or rewriting prompts. This Skill grounds every answer in current official OpenAI documentation with citations, so guidance on models, APIs, and prompting stays accurate. ## Core Features & Use Cases - Authoritative docs lookup: Searches and fetches pages from the OpenAI Developer Docs MCP server, with fallback restricted to official OpenAI domains. - Model selection and migration: Resolves the latest recommended model, preserves explicitly requested target models, and applies narrow model-string plus prompt upgrades with a compatibility gate. - Prompt-upgrade guidance: Provides bundled prompting and upgrade references for rewriting prompts when moving to newer models like GPT-5.5. - Use Case: A developer asks to migrate an existing integration from GPT-5.4 to the latest model. The Skill resolves the current latest model, checks compatibility, updates only the model string and directly related prompts, and reports any blocked paths. ## Quick Start Ask the assistant to check the official OpenAI docs for the latest recommended model and migrate your current API integration to it.
