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 high
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 →
- high Tool Misuse · line 183 Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.
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 | $0.02722 |
| Opus 5 | $0.00024 | $0.01361 |
| Sonnet 5 | $0.00010 | $0.00544 |
| Haiku 4.5 | $0.00005 | $0.00272 |
Grade A, and why
hps-academic-paper 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 — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Academic Paper(学术论文风)
A locked, single-theme deck plugin in the html-ppt-studio family, ported from
the MIT-licensed lewislulu/html-ppt-skill
academic-paper theme (assets/themes/academic-paper.css on the upstream
templates/deck.html scaffold). The register is a LaTeX article walking on
stage: paper-white ground, ink-black serif text, link-blue underlined
citations, italic kickers, hairline rules everywhere, zero rounded corners,
no shadows. It reads like Computer Modern even when Computer Modern is not
installed.
Start from example.html in this plugin folder. It is the proven seed: keep
its :root token sheet, base/slide-system CSS, academic device classes, deck
chrome and the entire navigation script verbatim, then replace only the slide
content. Do not rewrite the design system, and do not introduce any color or
font outside this spec.

What ships with it
3 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.

hps-academic-paper is a skill published in the GitHub repository nexu-io/open-design (95,309 stars, last pushed yesterday), licensed Apache-2.0. It adds 49 tokens to every session and 2,722 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.
