chatgpt-image-gen

chatgpt-image-gen is a skill for Claude Code, Codex from sologuy/chatgpt-web-handoff. It costs 76 tokens per session (1,650 once invoked), scanned A, original, MIT.

A command-line tool that uses a Chrome browser already signed in to ChatGPT to create images and save them as local files. It supports prompts, reference images, styles, aspect ratios, and output locations.

In plain words
What is it for?
Use it to create illustrations, mockups, concept art, or other images from text prompts, optionally guided by reference images and saved to a chosen folder.
Why use it?
It avoids setting up an image-generation API or API key, but requires an active ChatGPT web account and its available usage.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions Codex.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is [ -n "$CGIMG" ] || { echo "请先在项目仓库运行 ./scripts/install.sh --skills image" >&2; exit 1; }.

Good fit Use it to create illustrations, mockups, concept art, or other images from text prompts, optionally guided by reference images and saved to a chosen folder.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00076 $0.01650
Opus 5.5 $0.00030 $0.00660
Sonnet 5.5 $0.00015 $0.00330
Haiku 4.5 $0.00008 $0.00165

Security

Grade A, and why

chatgpt-image-gen scanned grade A with 0 findings 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 14d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ChatGPT 出图

驱动 Chrome 里已经登录的 ChatGPT Web 生成图片,并把图直接取回本地文件。 不走 API、不需要 key —— 用的就是你自己那个账号的网页版额度。

CGIMG=
for root in "$HOME/.claude" "$HOME/.agents" "$HOME/.codex" "$HOME/.hermes"; do
  if [ -x "$root/skills/chatgpt-image-gen/cgimg" ]; then
    CGIMG="$root/skills/chatgpt-image-gen/cgimg"
    break
  fi
done
[ -n "$CGIMG" ] || { echo "请先在项目仓库运行 ./scripts/install.sh --skills image" >&2; exit 1; }

"$CGIMG" "一只橘猫蹲在旧书店的木梯上,午后阳光斜射进来" \
  --style "写实摄影,浅景深" --aspect 3:2 --out ~/Desktop

返回 JSON,images[].path 就是落盘路径,另有尺寸、文件格式、大小与 SHA-256。 这是前台等待命令,生成时间受网页和账号状态影响。要审查文字或代码,用同仓的 chatgpt-handoff;本 Skill 可独立安装,不依赖另一个 Skill 的入口。


参数

参数 说明
prompt(位置参数) 要画什么。尽量具体——主体、场景、光线、氛围都写上,含糊的描述容易让它反问
--style 风格:写实摄影,浅景深 / 水彩 / 等距像素 / 胶片颗粒 …
--aspect 画面比例:16:9 / 3:2 / 1:1 / 9:16
--ref 参考图,可重复。会先上传再出图
--note 追加一句自定义要求,原样拼进提示词
--out 输出目录或文件名,默认当前目录;不覆盖已有文件
--max 最多保存几张,默认 4
--timeout 等待上限秒数,默认 600
--interval 轮询间隔秒数,默认 6
--keep-tab 跑完不关标签页(想继续在网页上追改图时用)
--allow-model-drift 明确接受实测模型不在预期列表;不要为绕过报错自行加上

档位固定极高,没有参数可调。 出图这件事没有省额度的必要,来回调档反而多一次 账号级写操作,还可能和别的自动化撞车。


提示词是自动包装过的

你给的描述会被包成一句明确的出图指令,末尾固定加上:

直接出图,不要向我提问、不要先描述你打算怎么画。只要图。

这句不是客套。ChatGPT 对含糊的描述习惯先追问风格或尺寸,一问就卡在那儿, 自动化这边只能干等到超时。所以宁可把要求写死。

即便如此,描述太抽象时它仍可能反问。超时返回里会带 assistant_text。 先检查保留的会话:已经发出的任务可能仍在生成,不能把超时当作未发送而直接重投。


会不会打扰你

会在已有 Chrome 会话里新开本次任务的标签页,不主动把 Chrome 窗口提到前台。 浏览器内的标签选择仍可能变化。成功时只关闭本次新页;加 --keep-tab 可保留。 失败时保留已经创建的本次页面,返回 page_id 和已知的 conversation_url,便于核查。


出错怎么办

情况 含义 怎么办
send_unknown 已跨发送边界,未确认结果 检查保留页面,不要直接再执行 cgimg,避免重复生成
timeout 已发送,尚未取得完整图片 读取 assistant_text 并检查保留会话;可能仍在生成,不能据此重投
image_download_failed 部分或全部图片取回/写盘失败 保留 images 中已成功的文件,核对 failed_images,从现有会话取图,不能重新生成冒充重试下载
ref_not_found 参考图路径不对 改路径。这一步在开浏览器之前就查,不浪费一轮
output_exists / output_type 输出文件已存在或扩展名不支持 换输出路径,保留已有文件
auth_required ChatGPT 掉登录了 去原浏览器登录后再执行
model_changed / effort_not_found 模型或档位不符 报出实测值,不静默降档;明确接受新模型后才可用 --allow-model-drift
browser_busy / effort_drifted 本次未发送,另一入口占锁或档位变化 核对未发送状态后可重试

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.
