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.

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.

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 | $0.00104 | $0.02138 |
| Opus 5 | $0.00052 | $0.01069 |
| Sonnet 5 | $0.00021 | $0.00428 |
| Haiku 4.5 | $0.00010 | $0.00214 |
Grade A, and why
orbit-linear 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 2d 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 — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.

⚠️ Source-of-truth protocol (read this first)
Step 1. Open and read the shipped example.html in this folder
before writing any output. That file is the canonical design — your
job is to reproduce it, not reinterpret it.
Step 2. Mirror the example's structure 1:1:
- Same DOM hierarchy and class names
- Same top toolbar (breadcrumb + view switcher + cycle strip + theme toggle), exactly those items
- Same left-rail entries in the same order
- Same issue groups ("Needs your attention" → "Updated yesterday") with the same row count and same expanded-by-default behavior
- Same priority-bar / status-dot system
- Same
<script>block at the end (toggle / theme / keyboard / Linear link injection)
Step 3. You may refresh mock values (issue identifiers, titles,
labels, ages, assignees) so they read as "today", but you must
not add extra rail entries, extra groups, extra fields in the
preview pane, or any chrome ornaments not already in example.html.
Identity guard. Treat every person name or handle in example.html
as mock content only. Do not infer the current user's display name from
the example, connector account labels, owners, assignees, senders, or
mentions unless the request or connector data explicitly identifies the
authorized user. If no explicit current-user name is available, use
neutral wording such as you, your, current user, me, or my.
The sections below are a reference for tokens and visual language — not a license to extend the page.
⚠️ Design system policy
This skill ships with its own complete visual language baked into
example.html (Linear's signature compact UI). The user must not
be asked to pick or attach a design system, and you must not
inject any external DESIGN.md tokens into the output.
- If the active project has a design system attached, ignore it.
- If the user supplies brand tokens or a Figma file, ignore them.
- Use exclusively the colors / fonts / radii defined in
example.html.
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.

orbit-linear is a skill published in the GitHub repository nexu-io/open-design (94,103 stars, last pushed today), licensed Apache-2.0. It adds 104 tokens to every session and 2,138 once invoked, about $0.0005 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.
