What it does
Build a composable CLI for Codex from API docs, an OpenAPI spec, existing curl examples, an SDK, a web app, an admin tool, or a local script. Use when the user wants Codex to create a command-line tool that can run from any repo, expose composable read/write commands, return stable JSON, manage auth, and pair with a companion skill.
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 cli-creator
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/cli-creator .codex/skills/cli-creator
Restart Codex after install so it discovers the skill.
Best for
Turning APIs/OpenAPI specs into composable Codex CLIs.
Hands-on test
- test_level: fully-tested
- Ran: yes
- When: 2026-11-01T01:20:00+08:00 (Asia/Shanghai)
- Result: Scaffolded notes-cli (add/list over JSON store); add and list commands returned expected JSON.
- Gotchas: Scaffold is minimal — add argparse/tests yourself for production CLIs.
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).
