SKILL.md

codex-image

Generate or edit images via OpenAI's Responses API by reusing the user's ChatGPT subscription — no OPENAIAPIKEY needed. The skill speaks to /v1/responses with the image_generation hosted tool while presenting an HTTP fingerprint indistinguishable from the official codex CLI.

When to invoke

Invoke this skill when the user asks to generate or edit an image and:

  • They explicitly mention codex-image / "codex image" / "use my ChatGPT

quota", or

  • They have an active codex login (~/.codex/auth.json exists) and have

not asked for an API-key based generator, or

  • They explicitly want to avoid paying for OPENAIAPIKEY usage.

Do not use this skill when:

  • The user has an OPENAIAPIKEY set and wants to use it directly (use a

generic Images API skill instead).

  • The user wants Google / Gemini / Adobe / other vendor image models.
  • The user wants pure local background removal (imagegen skill covers that).

Commands

codex-image generate "<prompt>" [--output-format png|webp|jpeg] [--out PATH] [--force]
codex-image edit --input REF1.png [--input REF2.png ...] "<prompt>" [--out PATH] [--force]
codex-image login
codex-image logout
codex-image status

Run codex-image --help for full flags. See [references/cli.md](./references/cli.md) for details and examples.

Prompting

See [references/prompting.md](./references/prompting.md). The guidance is compatible with the sibling imagegen skill so prompts can be reused.

Auth

The skill resolves an access token like so:

  1. Read $CODEX_HOME/auth.json (default ~/.codex/auth.json).
  2. If the access token is close to expiry, refresh it.
  3. If the file is missing or refresh fails, launch a PKCE OAuth browser flow

(binds 127.0.0.1:1455, falling back to :1457). On success, write auth.json so subsequent calls — including codex itself — reuse it.

Use codex-image login to force the OAuth flow. Use codex-image logout to clear tokens (keeps the file shape; codex will treat it as logged-out). Use codex-image status to inspect the current credential.

Output

By default images are written to:

$CODEX_HOME/generated_images/codex-image/<UTC>-<slug>.<ext>

with file mode 0o644. Pass --out PATH for an explicit destination.

Exit codes

Code Meaning
0 Success
2 User input error
3 File-system error
4 Auth/plan error (HTTP 403)
5 Network / rate-limit error (retries exhausted)
6 Partial success (stream broken)
7 API business error (response.failed)
130 User interrupt (Ctrl+C)
