Oh My PPT is a local-first desktop application that uses AI to create, edit, present, and export editable HTML-based slide presentations. It is for people making presentations, lessons, stories, reports, or pitches who want to describe their content and then adjust the resulting pages, visuals, animations, and layouts.
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 | $0.00000 | $0.00534 |
| Opus 5 | $0.00000 | $0.00267 |
| Sonnet 5 | $0.00000 | $0.00107 |
| Haiku 4.5 | $0.00000 | $0.00053 |
Grade A, and why
midcentury 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 4d 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
世纪中叶现代风格是那个黄金年代的美学缩影——芥末黄、焦橙、青绿在奶油色画布上交织出温暖的几何图案。这不是老气，而是经过时间沉淀的经典。Eames 椅子、Nelson 钟表、Saarinen 餐桌的精神都凝聚在每一页之中。
配色
标题 #78350f 深棕、正文 #92400e 焦糖，强调色 #ca8a04 芥末黄与 #0d9488 青绿是经典的世纪中叶组合。背景 linear-gradient(160deg, #fef3c7 0%, #fef9c3 50%, #fef3c7 100%) 是奶油色的双段渐变，温暖而柔和。卡片 rgba(255,255,255,0.9) 干净清爽，边框 rgba(180,83,9,0.2) 是淡焦橙色的轻描。
排版
中世纪现代字体——几何无衬线或带有曲线美的衬线。标题可以配合几何形状装饰，但不过分。字号层级优雅，行距宽松。
布局
有机几何形状作为装饰元素——杏仁形、星爆、原子图案。布局温暖但不拥挤，留白充足。内容区块之间用几何线条连接，而非硬边框。
动画
fade-up、stagger-list、morph-shape
适合场景
设计史叙事、家居美学展示、复古品牌故事、生活方式分享——需要传递「经典永不过时」的时刻。
配图
设计、家居、产品、文化生活和章节转场页，可用一件中世纪家具、安静室内或生活方式场景承接主题；暖色室内与有机几何保持简洁，不引入时代错位的物件。
事实信息、数据、流程、比较、清单和参数页不配图。
不要
- 不要使用现代科技感或冷色调
- 不要使用过于锐利的几何形状
- 不要让装饰喧宾夺主
- 不要追求「未来感」或「先锋感」
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.

midcentury is a skill published in the GitHub repository arcsin1/oh-my-ppt (1,943 stars, last pushed 4d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 534 tokens. 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 2026-08-30.
