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 | $0.00040 | $0.00878 |
| Opus 5 | $0.00020 | $0.00439 |
| Sonnet 5 | $0.00008 | $0.00176 |
| Haiku 4.5 | $0.00004 | $0.00088 |
Grade A, and why
ppt-keynote 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: Keynote 风格 PPT】
- 每张幻灯片是一个
<section class="slide">, 整体宽 1280 高 720, 居中显示, 背景渐变。 - 单页内容极简: 大标题 + 1-3 行支持文字; 或一张数据图; 或一个金句。
- 字号: 标题
text-7xl font-semibold tracking-tight, 副标题text-2xl text-neutral-500。 - 第一页是封面 (主题 + 演讲者 / 日期), 最后一页是 "Thanks." 或行动号召。
- 顶部右上角小指示器: 当前页 / 总页数。
- 加一段 JavaScript 监听 ArrowLeft / ArrowRight / 空格键切换 slide; 同时维护 hash (#/3)。
- 每页之间用 fade-in 动画。
- 保持留白, 数据卡片用 grid 布局对齐, 颜色克制。
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.

ppt-keynote is a skill published in the GitHub repository nexu-io/open-design (95,624 stars, last pushed today), licensed Apache-2.0. It adds 40 tokens to every session and 878 once invoked, about $0.0002 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 2026-09-03.
