Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00098 | $0.01834 |
| Opus 5 | $0.00049 | $0.00917 |
| Sonnet 5 | $0.00020 | $0.00367 |
| Haiku 4.5 | $0.00010 | $0.00183 |
Grade A, and why
cyxj-poster 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 12d 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.

Poster Design Generator
一句话生成大师级海报、书籍封面、专辑封面等设计作品。基于 Mondo 丝网印刷美学，支持 33+ 传奇设计师风格和 10 种写实摄影风格。
脚本调用
python3 ${CLAUDE_PLUGIN_ROOT}/skills/cyxj-poster/scripts/generate_mondo_enhanced.py "subject" "type" [options]
生图后端：gpt-image-2（GPTIMG2 @
api.chatgpt-code.com，OpenAI 兼容 HTTP）。 默认输出 2K 分辨率，统一用response_format=url取图后下载落地。
- 文生图走
/v1/images/generations；带参考图（--ip-ref/--input）时走/v1/images/edits（multipart）。- 需要环境变量
GPTIMG2_BASE_URL/GPTIMG2_API_KEY（未设置则从~/项目/自己的应用/密钥存储/.env读取）。- prompt 的 AI 扩写（
--ai-enhance）仍由 Gemini 文本模型完成，需GEMINI_API_KEY，与生图无关。
必填参数
| 参数 | 说明 | 示例 |
|---|---|---|
subject |
设计主题 | "Blade Runner", "Jazz Festival" |
type |
设计类型 | movie, book, album, event |
两个位置参数实际都可选：
type省略时默认movie；subject省略则只打印帮助退出（--list-styles除外）。--compare模式只吃 subject/type/比例/配色，会忽略--style/--input/--ip-ref/--output。
可选参数
| 参数 | 说明 | 默认值 |
|---|---|---|
--style |
艺术家风格（见 --list-styles） |
自动选择 |
--ai-enhance |
AI 优化 prompt（保留用户原始意图） | 关闭 |
--compare |
生成 3 种风格对比图，值为逗号分隔的恰好 3 个风格 key（如 kilian-eng,saul-bass,jock） |
无 |
--input |
输入图片路径（图生图转换） | 无 |
--ip-ref |
IP 角色参考图目录 | 无 |
--title |
直接渲染在海报上的标题文字 | 无 |
--colors |
配色偏好 | AI 建议 |
--aspect-ratio |
画幅比例 | 9:16（album 未显式指定时默认 1:1） |
--output |
自定义输出路径 | outputs/ |
--no-generate |
只输出 prompt，不生成图片 | 关闭 |
--list-styles |
列出所有可用风格 | — |
常用画幅比例
均为 2K 输出，边长对齐 16 的倍数：
| 比例 | 输出尺寸 | 用途 |
|---|---|---|
9:16 |
1440x2560 | 电影海报、书籍封面、手机竖屏（默认） |
16:9 |
2560x1440 | 文章配图、横屏封面 |
3:4 |
1536x2048 | 小红书配图 |
1:1 |
2048x2048 | 专辑封面、头像 |
4:3 |
2048x1536 | 通用横版 |
21:9等未在 2K 映射表内的比例会回退到 9:16（1440x2560）。需要超宽幅时请用上表内的比例。
调用示例
参数表即接口，按需自由组合。给一个多参数组合的形状参考（IP 角色海报）：
python3 ${CLAUDE_PLUGIN_ROOT}/skills/cyxj-poster/scripts/generate_mondo_enhanced.py "cyberpunk tech news" event --ip-ref ./ip-reference/ --title "A社新规：禁止第三方调用" --aspect-ratio 4:3 --colors "deep navy blue, neon cyan, magenta"
What ships with it
7 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.

cyxj-poster is a skill published in the GitHub repository chenyuxiaojin/xiaochen-skills (6 stars, last pushed 8d ago), licensed MIT. It adds 98 tokens to every session and 1,834 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
