OpenAI Docs

Provide authoritative, current guidance from OpenAI developer docs using the developers.openai.com MCP server. "Docs MCP" means mcp__openaiDeveloperDocs__search_openai_docs and mcp__openaiDeveloperDocs__fetch_openai_doc; for API reference, schema, parameter, or required-field questions, also use mcp__openaiDeveloperDocs__get_openapi_spec when available. Official-domain web search is fallback after those tools are unavailable or unhelpful. Broad Codex questions use the manual helper before Docs MCP. This skill also owns model selection, API model migration, and prompt-upgrade guidance.

Host routing

• In Codex, use the documented OpenAI Developer Docs MCP wrappers and Codex manual helper when those capabilities are exposed.
• In Claude Code, including sessions backed by the GLM Coding Plan endpoint, inspect the active MCP tools before naming a wrapper. Use the configured OpenAI Developer Docs MCP if present; otherwise use Claude Code web retrieval restricted to official OpenAI domains and the bundled local resolver/manual scripts where applicable.
• A third-party Claude Code model endpoint changes the inference provider; it does not make Codex-only tools or wrapper names available.
• In GitHub Copilot or any other host, map the workflow to the current tool list and preserve the same official-domain and citation requirements.
• Never claim a Codex manual helper, MCP operation, or host-native docs tool ran unless the active session exposed it and the call completed.
