Build, scaffold, refactor, and troubleshoot ChatGPT Apps SDK applications that combine an MCP server and widget UI. Use when Codex needs to design tools, register UI resources, wire the MCP Apps bridge or ChatGPT compatibility APIs, apply Apps SDK metadata or CSP or domain settings, or produce a docs-aligned project scaffold. Prefer a docs-first workflow by invoking the openai-docs skill or OpenAI developer docs MCP tools before generating code.

Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'build-chatgpt-app' ] || [ -L ~/.agents/skills/'build-chatgpt-app' ]; then echo 'A skill folder named build-chatgpt-app already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/openai/plugins' "$d" && git -C "$d" checkout --quiet 'd420d13051bffe4543ed39e30fa46b87148e47dd' -- 'plugins/openai-developers/skills/build-chatgpt-app' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/openai-developers/skills/build-chatgpt-app' ~/.agents/skills/'build-chatgpt-app' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'build-chatgpt-app' ~/.claude/skills/'build-chatgpt-app' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
