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.

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 | $0.00067 | $0.01677 |
| Opus 5.5 | $0.00027 | $0.00671 |
| Sonnet 5.5 | $0.00013 | $0.00335 |
| Haiku 4.5 | $0.00007 | $0.00168 |
Grade A, and why
motion-future 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 yesterday.
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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
The Future Is Already Here
A 20-second electric-blue tech reel, rebuilt from the viral original: 3D cubes, a word tunnel, liquid chrome type, a FUTURE.EXE desktop, a countdown, glass objects and a chrome FUTURE hero, cut to 120 BPM. example.html is the finished reference — start from it.
Source
A remake of a viral post by Douyin: https://www.douyin.com/video/7690393045783346918 (6,439 likes · 2,164 saves · 1,285 shares on Douyin (as of 2026-10-12)). The composition is rebuilt in code from the published piece; the soundtrack is original.
Reference files
Copy example.html, assets/gsap.min.js, assets/three-addons.js, assets/unbounded-black-glyphs.js, assets/jetbrains-mono-OFL.txt, assets/jetbrains-mono-subset.ttf, assets/soundtrack.mp3, assets/three.min.js.gz, assets/unbounded-OFL.txt, assets/unbounded-subset.ttf into the composition, preserving the assets/ path.
Font licenses travel with their fonts. Use these frozen local bytes; no runtime
script or font CDN is needed.
The gallery loads assets/three.min.js. The frozen reference package carries
the same Three.js bytes compressed as assets/three.min.js.gz to fit the
per-file budget. Before rendering, decompress it into the composition:
gzip -dc "<reference-root>/assets/three.min.js.gz" > "<composition-root>/assets/three.min.js".
Both placeholders are the actual reference and composition directories in this
task. Keep the HTML script URL pointing to the decompressed .js file.
Art direction
- Electric blue, black, white and chrome; heavy display type Unbounded Black with JetBrains Mono for the HUD (both SIL OFL, bundled).
- Three.js for the 3D layer (
#gl) under a 2D overlay canvas (#ui). All scenes are readable code insideexample.html. assets/three-addons.jsholds the three.js add-ons the film needs (RoomEnvironment, FontLoader, TextGeometry), unbundled.assets/unbounded-black-glyphs.jsholds Unbounded Black outlines for every 3D word: A–Z, a–z, 0–9 and common punctuation.- The original is a 62s Chinese post; this reference is a 20s English highlight cut.

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.

motion-future is a skill published in the GitHub repository nexu-io/open-design (101,352 stars, last pushed today), licensed Apache-2.0. It adds 67 tokens to every session and 1,677 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 2026-10-15.
