OpenAI Docs

Provide authoritative, current guidance from OpenAI developer docs using the developers.openai.com MCP server. Always prioritize the developer docs MCP tools over web.run for OpenAI-related questions. This skill may also load targeted files from references/ for model-selection and GPT-5.4-specific requests, but current OpenAI docs remain authoritative. Only if the MCP server is installed and returns no meaningful results should you fall back to web search.

Quick start

• Use mcp__openaiDeveloperDocs__search_openai_docs to find the most relevant doc pages.
• Use mcp__openaiDeveloperDocs__fetch_openai_doc to pull exact sections and quote/paraphrase accurately.
• Use mcp__openaiDeveloperDocs__list_openai_docs only when you need to browse or discover pages without a clear query.
• Load only the relevant file from references/ when the question is about model selection or a GPT-5.4 upgrade.
