What it does
Use when the user asks how to build with OpenAI products or APIs, asks about Codex itself or choosing Codex surfaces, needs up-to-date official documentation with citations, help choosing the latest model for a use case, or model upgrade and prompt-upgrade guidance; use OpenAI docs MCP tools for non-Codex docs questions, use the Codex manual helper first for broad Codex self-knowledge, and restrict fallback browsing to official OpenAI domains.
This entry summarizes the public skill for discovery. Prefer the upstream SKILL.md for the full instruction text (we do not paste restricted or lengthy proprietary prompt bodies).
Install & usage
Codex
Inside Codex, use the skill installer (repo is deprecated as a catalog but curated skills remain usable):
$skill-installer openai-docs
Or copy from GitHub:
mkdir -p .codex/skills
git clone --depth 1 https://github.com/openai/skills.git /tmp/openai-skills
cp -R /tmp/openai-skills/skills/.curated/openai-docs .codex/skills/openai-docs
Restart Codex after install so it discovers the skill.
Best for
Accurate guidance when building on OpenAI products/APIs.
Hands-on test
- test_level: fully-tested
- Ran: yes
- When: 2026-11-01T01:20:00+08:00 (Asia/Shanghai)
- Result: Looked up platform.openai.com/docs/guides/text; raw urllib got 403, WebFetch succeeded; wrote ANSWER.md on Responses API preference.
- Gotchas: Direct HTTP from some datacenter IPs is 403 — use a browser/WebFetch path.
Money-saving tip
Prefer ChatGPT Go ($8/mo US) or Plus ($20/mo) before Pro tiers; Business annual Standard seats are $20/user/mo vs $25 monthly. Nonprofit Standard seats: $8 annual / $10 monthly (help.openai.com).
