design-extract is a command-line tool that examines live websites with a headless browser and turns their visual and interaction rules into design-system files. It is used by developers and designers to extract tokens, component details, responsive behavior, accessibility findings, and platform-specific outputs, while the catalogue commands, skills, plugin, and rule expose that process to coding agents.
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 | $0.00000 | $0.00349 |
| Opus 5.5 | $0.00000 | $0.00140 |
| Sonnet 5.5 | $0.00000 | $0.00070 |
| Haiku 4.5 | $0.00000 | $0.00035 |
Grade A, and why
studio 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 1mo 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.
What it actually says
Launch designlang studio, a tiny local web app that turns the most recent extraction into a living, editable design system. Editing a token restyles a wall of real components and a rebuilt page instantly; you can toggle a generated dark mode, inspect easing curves and choreography in the Motion tab, and export the edited system back out as DTCG tokens, CSS variables, and a Tailwind theme — or copy a shareable link that encodes the edits.
npx designlang studio $ARGUMENTS
This starts a local HTTP server (default port 4837) and prints a URL. Tell the
user to open it in their browser. It reads the latest *-design-tokens.json
from ./design-extract-output/ by default — if there is no extraction yet, run
/extract <url> or /site <url> first.
Useful flags via $ARGUMENTS:
| Flag | Effect |
|---|---|
--dir <dir> |
directory to read the latest extraction from |
--port <n> |
port for the local server (default 4837) |
The server runs until the user stops it (Ctrl+C). Do not block on it — surface the URL and let the user drive.

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.

studio is a command published in the GitHub repository Manavarya09/design-extract (4,268 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 349 tokens. 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 2026-08-30.
Other commands, from other repositories
typography
Run a typography-only audit — scale detection, font count, body size, line height, fluid type. Scoped variant of /ui-ux-suite:audit.
dashboard-layout
Design and build a complete dashboard layout — sidebar navigation, KPI cards, chart areas, data tables, filter bar, and responsive behavior. Outputs production-ready HTML/CSS.
color-specialist
Use when colour is failing. Contrast below AA, a palette with no system behind it, dark mode that is only inverted light mode, or semantic colours that carry no meaning.
dark-mode-specialist
Use when dark mode looks wrong. Pure black surfaces, elevation that disappears, brand colours that vibrate against dark, a white flash on load, or a mode toggle that does not persist.
motion-designer
Use when animation feels wrong. Transitions too slow or too bouncy, motion with no purpose, blanket transitions on every property, no reduced-motion support, or animation that drops frames.
responsive-design-specialist
Use when a layout breaks between sizes. Arbitrary breakpoints, type that does not scale, images that blow out the grid, or a desktop design retrofitted onto mobile.
