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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.02281 |
| Opus 5 | $0.00024 | $0.01141 |
| Sonnet 5 | $0.00010 | $0.00456 |
| Haiku 4.5 | $0.00005 | $0.00228 |
Grade A, and why
kami-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 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.
How it starts
The opening of the file, as written. The whole thing — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.
kami-deck
Sister skill to kami-landing. Produces a single
self-contained HTML file: a horizontal magazine-style swipe deck in
the kami (紙 / 纸) design system — print rhythm, ink-blue accent,
serif at one weight, no italic, no cool grays.
The navigation model is intentionally borrowed from the
guizang-ppt skill — ←/→ arrow keys, wheel /
swipe, ESC for the overview grid. The aesthetic stays kami: parchment
content slides, ink-blue cover and chapter slides, serif everywhere.
Design system source of truth:
design-systems/kami/DESIGN.md. Read it before shipping. Tokens, type rules, and forbidden colors all live there. Slide-specific scale ratios (macro × 1.6, letter-spacing × 0.6 vs. print) are documented in §3 "Hierarchy" and §5 "Layout Principles · Slides".
What you get
- N viewport-sized slides (6-15 is the sweet spot) laid out horizontally on one transformed flex track.
- Cover and chapter slides flip background to ink-blue
(
#1B365D) with ivory text — the only place dark theme is used. - Content / stats / quote / CTA slides stay on parchment
(
#f5f4ed) with serif at weight 500. - Per-slide chrome strip: brand mark · deck title · live slide
counter (
01 / 09). - Tabular-nums on every counter, metric, page number.
- Coral-free — kami's accent is ink-blue. Progress bar and dot nav are ink-blue too.
- Keyboard / wheel / touch nav, ESC overview grid, dot indicator.
- Multilingual stack — EN / zh-CN / ja, set on
:rootvia thelanguageparameter.
Slide types
| Kind | Background | Use it for |
|---|---|---|
cover |
ink-blue | Title plate at the start. Centered serif title + tagline. |
chapter |
ink-blue | Roman/Arabic numeral chapter divider. |
content |
parchment | Section number + title + body + optional bullets. |
stats |
parchment | 3-4 metric cells (value · label · sub). |
quote |
parchment | Pull quote with ink-blue left rule + author signature. |
cta |
parchment | Closing pitch + 1-2 buttons. |
end |
ink-blue | Mega serif kicker word + colophon footer. |
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-deck is a skill published in the GitHub repository nexu-io/open-design (94,527 stars, last pushed today), licensed Apache-2.0. It adds 49 tokens to every session and 2,281 once invoked, about $0.0002 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.
