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.

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 | $0.00045 | $0.02809 |
| Opus 5 | $0.00023 | $0.01404 |
| Sonnet 5 | $0.00009 | $0.00562 |
| Haiku 4.5 | $0.00005 | $0.00281 |
Grade A, and why
ve-terminal-mono 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

Terminal Mono(等宽终端)
A locked, single-theme deck plugin derived from the MIT-licensed
nicobailon/visual-explainer
slide-deck template, restyled with the Terminal Mono aesthetic from its
references/slide-patterns.md. Developer-native and typographically strict:
near-black ground, monospace everything, one green voice, a faint dot grid.
Zero skeuomorphism, zero effects. No $ prompts, no red/yellow/green
window chrome, no CRT scanlines, no vignettes, no glows. This theme stands on
typographic discipline and the dot-grid texture alone. (The skeuomorphic
"terminal theater" look belongs to a different plugin — do not drift there.)
Start from example.html in this plugin folder. It is the proven seed: copy
its :root tokens (both themes), deck/slide CSS, dot-grid treatment, and the
entire SlideEngine 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.
Design tokens (locked — list verbatim in :root)
Dark is the default theme; light mode switches automatically via
prefers-color-scheme: light. Both blocks are part of the locked spec —
dual-theme support is the visual-explainer family signature and must ship in
every deck.

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.

ve-terminal-mono is a skill published in the GitHub repository nexu-io/open-design (95,309 stars, last pushed yesterday), licensed Apache-2.0. It adds 45 tokens to every session and 2,809 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.
