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.

- NVIDIA SkillSpector warn
SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Agent Snooping · line 12 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
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 | $0.00064 | $0.01141 |
| Opus 5 | $0.00032 | $0.00571 |
| Sonnet 5 | $0.00013 | $0.00228 |
| Haiku 4.5 | $0.00006 | $0.00114 |
Grade A, and why
html-ppt-taste-editorial 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 11d 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.

How it starts
The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HTML PPT — Editorial Minimalism
A 16:9 deck for the briefs that hate neon: investor updates, design reviews, internal manifestos, lecture decks. Reads like a print supplement, not a SaaS landing.
Source
Distilled from Leonxlnx/taste-skill — skills/minimalist-skill/SKILL.md. The deck system follows the project deck convention: each .slide is a 100vw × 100vh section, the active slide carries .active / .is-active, and the baked example owns keyboard, wheel, touch, and dot navigation inside the gallery iframe. No-script and print fallbacks keep every slide visible. See example.html in this directory.
Hard rules
- Substrate: warm off-white
#FBFBFA/#F7F6F3. Foreground off-black#1A1A19. Never pure white or pure black. - Type pairing: display in serif (Instrument Serif / Newsreader / Lyon), body in grotesque (Inter Tight / Switzer), meta in mono (JetBrains Mono).
- Display scale per slide: title
clamp(56px, 6.5vw, 96px)italic-capable serif, line-height1.05, tracking-0.025em. - Hairline only:
1px solid #EAEAEA— borders, dividers, table cells. No drop shadows. - One accent color chosen from the muted-pastel pairs (e.g. sage
#346538on#EDF3EC, or red#9F2F2Don#FDEBEC). Used sparingly — eyebrow dot, chart fill, call-out chip. Never as a slide background. - Slide padding: generous (
72px 96pxminimum). Title at most 14ch wide. - Eyebrow: every slide opens with a mono uppercase eyebrow
letter-spacing: 0.18emand a section number01 / 09. - Page numbers: mono, bottom-right corner.
Banned
- Inter (use Inter Tight if you must, but prefer Switzer / SF Pro). No Roboto, Open Sans.
- Heavy drop shadows. Glow. Gradient text.
- 3-equal-card feature rows. Use uneven hairline-divided columns instead.
- Emojis in text or as bullet markers — use
—or no marker. - Full-bleed photography on every slide. Use one or two image slides; reserve them.
- AI-cliché copy ("Elevate", "Unleash", "Seamless", "Next-Gen").
- Slide transitions noisier than fade-in.
What ships with it
1 file 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.
