OpenDesign is an open-source, local-first desktop app that lets coding agents create prototypes, dashboards, slide decks, images, video, and design systems as exportable files. It is used by people working with agent runtimes such as Claude Code, Codex, Cursor, and DeepSeek Harness. The catalogue add-ons extend the OpenDesign workflow with skills, instructions, commands, and plugins.
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.

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 | $0.00025 | $0.00681 |
| Opus 5 | $0.00013 | $0.00341 |
| Sonnet 5 | $0.00005 | $0.00136 |
| Haiku 4.5 | $0.00003 | $0.00068 |
Grade A, and why
card-xiaohongshu 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 8d 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.

What it actually says
【模板: 小红书图文卡片】
- 输出 N 张连续卡片, 每张
w-[1080px] h-[1440px], 用 flex 纵向排列方便整体截图也方便单张截图。N 由【用户内容】信息量决定: 短内容 3-6 张起步, 长内容应更多 (小红书平台单帖最多 18 图, 通常 9 张以内最佳); 一张卡只承载一个核心观点。 - 第一张是封面: 巨大的标题 + 1 行副标题 + 一个吸引人的标签 (类似 "干货预警" / "建议收藏")。
- 中间几张展开正文, 每张一个核心观点, 配 emoji + 短句 + 1-2 个例子。
- 最后一张是总结 + 行动号召 (关注 / 收藏 / 评论)。
- 配色: 选择柔和的莫兰迪色或粉色系; 元素圆润, 大量留白。
- 字号大、行距宽、对比强（小红书在手机上看, 小字根本看不清）。
- 每张卡片右下角小水印 (作者名 / 日期)。
What ships with it
2 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.
