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
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

- NVIDIA SkillSpector warn
SkillSpector: 3 findings, 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 →

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 | $0.00049 | $0.02486 |
| Opus 5 | $0.00024 | $0.01243 |
| Sonnet 5 | $0.00010 | $0.00497 |
| Haiku 4.5 | $0.00005 | $0.00249 |
Grade A, and why
open-design-landing-deck 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 7d 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 — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.
open-design-landing-deck
Sister skill to open-design-landing. Same
Atelier Zero visual system (warm paper, Inter Tight + Playfair Display,
italic-serif emphasis, coral dots), but paginated as a horizontal
magazine-style swipe deck instead of a long scrolling page.
The navigation model is intentionally borrowed from the
guizang-ppt skill — ←/→ arrow keys, wheel /
swipe, ESC for the overview grid — so it feels like a print magazine
flipping page by page rather than a web slide deck scrolling.

(one viewport per slide, horizontal swipe)
What you get
- A single self-contained HTML file with N viewport-sized slides laid out horizontally on one transformed flex track.
- Keyboard navigation:
←/→·↑/↓· PageUp/PageDown · Space · Home/End. - Wheel + touch swipe (with momentum guard so a single trackpad flick doesn't overshoot).
- Per-slide chrome strip: brand mark, deck title, location,
Roman-numeral year, live slide counter (
01 / 11). - Coral progress bar at the bottom that fills as you advance.
- Dot indicator strip near the bottom; click any dot to jump.
- ESC overview grid — scaled thumbnails of every slide, click to
jump. Mirrors
guizang-ppt's overview UX. - Reuses the same 16-slot image library as the sister skill — no duplicate assets.

What ships with it
5 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.
