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 | $0.00103 | $0.00972 |
| Opus 5 | $0.00051 | $0.00486 |
| Sonnet 5 | $0.00021 | $0.00194 |
| Haiku 4.5 | $0.00010 | $0.00097 |
Grade A, and why
digital-eguide 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 8d 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.

The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Digital E-Guide Skill
Produce a two-page digital guide preview side-by-side. Cover on the inline-start, inside spread on the inline-end. Lifestyle creator tone, lots of negative space, serif display headings, careful column rhythm.
Workflow
- Read the active DESIGN.md (injected above). Pick a serif display token for the title (italic ligatures encouraged), a body serif for long-form, and a mono token for stats / labels.
- Pick the topic + author from the brief. Generate a real title (e.g. "The Creator's Style & Format Guide"), a real subtitle, and a one-line author byline.
- Layout — center two pages on a tinted backdrop:
- Page 1 — cover:
- Eyebrow ("STYLE & FORMAT GUIDE FOR CREATORS").
- Display title with mixed weights and one italic flourish word
("The Creator's Style & Format guide" —
&andguideitalic). - 3-cell stat row ("16 PRINCIPLES OF STYLE", "38 DOS & DON'TS",
"1 BLOCK, ZERO TEMPLATES") in mono, separated by
·. - "What's inside" header with a 2-column TOC (chapters + page numbers in mono, leader dots).
- Footer: "FIND YOUR VOICE" + page 01 mono.
- Subtle decorative dot or sticker (CSS) in a corner.
- Page 2 — spread:
- Eyebrow with chapter number + name ("CHAPTER 02 · TONE").
- Display sub-title ("Write like you talk — only sharper.").
- 2-column body: opening paragraph + a numbered 4-step list ("01 Pick the rule", "02 Drop the filler"…).
- Pull-quote pinned to inline-end: for Latin scripts use large italic display and accent color; for Arabic, Persian, and Urdu use regular or light emphasis (no italics); for Hebrew use regular or light emphasis (no italics). Include attribution. (script-aware)
- Bottom strip with "EXERCISE" callout (mono label + 1 sentence prompt in italic).
- Footer: chapter title + page 18 mono.
- Page 1 — cover:
- Write a single HTML document:
<!doctype html>through</html>, CSS inline.- Pages are 600×860 paper-tone cards with 6px shadow, slight rotation opposing each other (±0.6deg) for a magazine-on-desk feel.
data-od-idon cover, spread, toc, pull-quote, exercise.
- Self-check:
- Type hierarchy is editorial — title owns page 1, sub-title owns page 2.
- Italic accent appears once per page.
- Mono used only for labels, stats, and TOC numbers.
What ships with it
1 file 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.
