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.

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 | $0.00104 | $0.02974 |
| Opus 5 | $0.00052 | $0.01487 |
| Sonnet 5 | $0.00021 | $0.00595 |
| Haiku 4.5 | $0.00010 | $0.00297 |
Grade A, and why
open-design-landing 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.

How it starts
The opening of the file, as written. The whole thing — 298 lines — stays where its author put it; the contents beside it link to each section on GitHub.
open-design-landing
Build a single-page editorial landing site (or a slide deck — see the
sibling open-design-landing-deck skill)
in the Atelier Zero design system: warm-paper background, Inter
Tight + Playfair Display, italic serif emphasis spans, dotted hairline
rules, coral terminating dots, scroll-reveal motion, and 16 surreal
collage plates.
This is the canonical OpenDesign marketing-page recipe — the example output is the very page you see at open-design.
The skill is fully parameterized. The agent fills one typed
inputs.json from the user's brief; the composer turns that JSON +
the canonical styles.css into a deployable artifact.

What you get
A single HTML file with all of:
- Editorial topbar (volume / issue / language strip), Headroom-style sticky nav with live GitHub star count.
- 8 numbered Roman-numeral sections with paper-textured background: hero (with 3 stat rings + 4-step index), about, capabilities (4 cards), labs (5 cards + filter pills + progress bar), method (4 steps with thumbnails), selected work (dark slab + 2 tilted cards), testimonial (pull quote + 5 partner glyphs), CTA (ribbon + email pill).
- Footer with 4 link columns + huge italic-serif kicker word.
- Scroll-reveal motion on every section (IntersectionObserver, respects
prefers-reduced-motion). - Fully responsive at 1280 / 1080 / 880 / 560 breakpoints.
Workflow contract
Run these four steps in order. The agent should complete each step before moving on, and prefer asking the user a focused question over inventing copy.
What ships with it
36 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.

open-design-landing is a skill published in the GitHub repository nexu-io/open-design (95,309 stars, last pushed yesterday), licensed Apache-2.0. It adds 104 tokens to every session and 2,974 once invoked, about $0.0005 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.
