Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 4 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 59 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00089 | $0.01086 |
| Opus 5.5 | $0.00036 | $0.00434 |
| Sonnet 5.5 | $0.00018 | $0.00217 |
| Haiku 4.5 | $0.00009 | $0.00109 |
Grade B, and why
codex-image scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- On success → saves token to `~/.chatgpt_auth.json` (chmod 600, token + timestamp only) How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex Image Generation
Generate images via chatgpt.com/backend-api/codex/responses using the image_generation tool (gpt-image-2).
Requirements
- A ChatGPT account (token is fetched automatically via browser session)
- No manual token setup needed — the skill handles auth automatically
Auth Token Resolution (in order)
--tokenargument (CLI only)CODEX_IMAGE_TOKENenvironment variable--token-fileargument (CLI only)~/.chatgpt_auth.jsoncache (valid for 8 hours)- Auto login flow — fetches from
https://chatgpt.com/api/auth/sessionviaminis-browser-use:- If already logged in → token extracted and saved to cache immediately
- If not logged in → opens
chatgpt.com/auth/loginin the browser, then polls every 10s in a new tab for up to 5 minutes - On success → saves token to
~/.chatgpt_auth.json(chmod 600, token + timestamp only) - Token is never printed to stdout or logs — it stays in the cache file only
Usage
Text-to-image
python3 scripts/codex_image.py "a cute rabbit on a light background" \
--output rabbit.png \
--model gpt-5.4 \
--effort low
Image-to-image / reference image
python3 scripts/codex_image_edit.py "turn this person into a cinematic iOS AI assistant portrait" \
--image reference.jpg \
--output portrait.png \
--model gpt-5.4 \
--effort low
codex_image_edit.py encodes the local reference image as a base64 data URL and sends it as multimodal input (input_text + input_image) to the same Codex responses endpoint, then asks the image_generation tool to create a new image from the reference.
Parameters
| Parameter | Default | Description |
|---|---|---|
prompt |
(required) | Image description or edit instruction |
--image |
(edit only, required) | Local reference image path for image-to-image generation |
--output |
codex_image.png / codex_image_edit.png |
Output file path |
--model |
gpt-5.4 |
Codex model |
--effort |
low |
Reasoning effort: low/medium/high |
--token |
- | Access token directly (skips auto auth; text-to-image script only) |
--token-file |
- | File containing token (skips auto auth; text-to-image script only) |
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 1mo ago First seen · 93 lines · 89 tokens per session scan B 2ffe4029bb45
codex-image is a skill published in the GitHub repository OpenMinis/MinisSkills (502 stars, last pushed 2d ago), licensed MIT. It adds 89 tokens to every session and 1,086 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
