No more copy-pasting outdated docs. Your coding agent now has real-time access to the latest SDK specs. The skill is open source and available on GitHub - link here: https://github.com/vincentmcleese/cha... ------ Here's what we cover: → What is the OpenAI Docs MCP?: A plugin for any coding agent that dynamically searches and reads the latest OpenAI developer documentation. No authentication required. → Why This Matters: OpenAI docs update constantly. Copy-pasting means working with stale information within weeks. The MCP keeps you current automatically. → Skills Explained: What skills are, how they work like "IKEA manuals" for agents, and why they're taking off across coding agents and LLM clients. → The ChatGPT Apps SDK Skill: A purpose-built skill that connects to the Docs MCP to fetch live documentation when building ChatGPT apps. Includes templates, tool annotations, and submission guidelines. → Live Build Demo: We build a yo-yo store app with instant checkout from scratch using Cursor and Codex - watching the agent pull docs in real-time. → Tool Annotations & Submission Checklist: How the skill automatically applies OpenAI's tool annotation requirements and generates a checklist for app store submission. → Testing with MCP Jam: How to run your app locally and test it in an MCP inspector before connecting to the ChatGPT platform. The skill always pulls current docs - so if OpenAI updates something tomorrow, your next build uses the new specs automatically. 📌 Ghost Team: https://www.ghostteam.ai 📫 Newsletter: https://elliotgarreffa.beehiiv.com/ Follow for More AI Content: ➡️ LinkedIn:   / elliotgarreffa   ➡️ X: https://x.com/elliot_garreffa ➡️ TikTok: /elliotagarreffa ➡️ Instagram: /elliotagarreffa Timestamps 01:30 – Adding the Docs MCP to Cursor 03:00 – Demo: Querying "What is a ChatGPT app?" 04:30 – What are skills?
