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.

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 | $0.00081 | $0.02533 |
| Opus 5.5 | $0.00032 | $0.01013 |
| Sonnet 5.5 | $0.00016 | $0.00507 |
| Haiku 4.5 | $0.00008 | $0.00253 |
Grade A, and why
kami-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 1mo 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 — 234 lines — stays where its author put it; the contents beside it link to each section on GitHub.
kami-landing
Produce a single-page document in the kami (紙 / 纸) design system. The aesthetic borrows from editorial print, technical white papers, and old typewritten correspondence — the goal is good content on good paper, not modern app UI.
Design system source of truth:
design-systems/kami/DESIGN.md. Read it before shipping. Tokens, type rules, the "ten invariants", and forbidden colors all live there.
What you get
A single self-contained HTML file with:
- Warm parchment canvas (
#f5f4ed) — never#ffffff. - Single chromatic accent — ink-blue (
#1B365D), used on the section number, the headline accent word, the left rule of the manifesto, and the metric values. Anywhere else, ink-blue must cover ≤ 5% of the document surface area. - Serif at one weight (500) for hierarchy — Charter (EN),
TsangerJinKai02 / Source Han Serif (CN), or YuMincho (JA),
selected by the
languageparameter. No italic anywhere. - Tight print rhythm — line-heights 1.10–1.55, letter-spacing per language (0 for EN, 0.35px for CN, 0.02em for JA).
- Numeric stacks set in
font-variant-numeric: tabular-numsso metric columns and pagination digits sit cleanly aligned. - Depth via 1px rings + whisper shadows (
0 4px 24px rgba(0,0,0,0.05)). No hard drop shadows, no neumorphism, no backdrop-filter blurs. - Tag fills as solid hex (e.g.
#E4ECF5), neverrgba()— print renderers double-paint alpha tags. - Responsive at 1280 / 980 / 768 / 560.
Page structure
1. Eyebrow row — locale switcher · edition · version (12px sans uppercase)
2. Hero — display headline (96–106px serif 500), tagline (21px),
three hero-token chips (paper-tinted)
3. Manifesto — pull paragraph in serif 400, 20px, 1.65 LH, with
ink-blue left-rule and signature footer
4. Metrics row — 3-6 cells: value (24px serif 500 ink-blue, tabular-nums),
label (12px serif 500 olive)
5. Chapters — numbered (`01`, `02`, …) ink-blue serif 500 14px,
section title 28-32px, body 14-15px
6. Footer — kicker word (mega serif 500), license · year · contact,
three-column site index in 12px serif 500
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.

kami-landing is a skill published in the GitHub repository nexu-io/open-design (103,954 stars, last pushed today), licensed Apache-2.0. It adds 81 tokens to every session and 2,533 once invoked, about $0.0003 per session on Opus 5.5. 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.
