Connect a ChatGPT or Codex subscription via OAuth device-code login. Use when the user wants to sign in with their ChatGPT Plus, Pro, or Team account (e.g. "use my Codex subscription", "log in with ChatGPT").
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 🔐 ChatGPT / Codex OAuth Onboarding
Use the user's existing **ChatGPT or Codex subscription** for `gpt-5-codex`, `gpt-5`, `gpt-5-mini` access — without an API key.
This is a **script-mode skill** — no tools registered. Read this file, then call the exports from a `bash` block.
## See also
- `byok-custom-model` skill — for vendor-key BYOK setup (DIFFERENT mechanism, NOT OAuth)
- `config/context/references/model-onboarding.md` — overall model-selection landscape

## When to use this skill
✅ **Use** when the user EXPLICITLY says one of:
- "Sign in with my ChatGPT account"
- "Use my Codex subscription"
- "Connect my ChatGPT Plus / Pro / Team / Enterprise"
- "Login with OpenAI / ChatGPT"
❌ **Do NOT use** for:
- BYOK / API-key-based setup ("Add OpenAI API key", "I have an OpenAI key")
- Other vendors that sound similar (Anthropic, Gemini, Qwen, etc.) → use `byok-custom-model`
- "Add the OpenAI model" without subscription context — ASK first whether they want OAuth (subscription) or BYOK (API key)

How to install
mdr add starchild-ai-agent/official-skills/chatgpt-codex-onboarding@sha256:3e129102cacaa387The line at the top of this page pins the label v2.0.4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
