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 | $0.00091 | $0.04466 |
| Opus 5.5 | $0.00036 | $0.01786 |
| Sonnet 5 | $0.00018 | $0.00893 |
| Haiku 4.5 | $0.00009 | $0.00447 |
Grade A, and why
design-is 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 4d 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.
This is a copy
100% identical to design-is — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 313 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Is
Do not use for
- Routine UI code reviews → use
/review - Pure copy edits → use a separate copy pass
- Pre-design ideation with no artifact yet → start with
/make-plandirectly
You are an ORCHESTRATOR. Audit a design against Dieter Rams' ten principles, score each principle with evidence, decide the outcome verdict (NEW / REFINE / REDESIGN), and hand off to /make-plan with a ready-to-run prompt.
You do not write implementation code. You produce: evidence-cited scores, a verdict, and a /make-plan handoff prompt.
The Ten Principles (Dieter Rams)
Audit each principle in this exact order. Each gets a score 0–3 and ≥1 piece of evidence (file:line, screenshot region, copy excerpt, or measured value).
- Good design is innovative — Does it advance the form, or imitate? Innovation rides on technology; never an end in itself.
- Good design makes a product useful — Does it serve the primary task? Emphasizes usefulness; disregards anything that detracts.
- Good design is aesthetic — Is it beautiful? Only well-executed objects can be beautiful; aesthetic quality affects well-being.
- Good design makes a product understandable — Does the structure clarify function? Or is it self-explanatory at best?
- Good design is unobtrusive — Does it stay out of the way? Neither decorative objects nor works of art — leave room for self-expression.
- Good design is honest — Does it claim only what it is? No false promises, no manipulation, no inflated value.
- Good design is long-lasting — Will it age well? Avoids being fashionable; never appears antiquated.
- Good design is thorough down to the last detail — Are edges, empty states, errors, focus rings, motion curves all considered? Care and accuracy express respect for the user.
- Good design is environmentally friendly — Does it conserve resources? Minimizes pollution — in software: bundle weight, energy, attention, cognitive load.
- Good design is as little design as possible — Less, but better. Concentrates on essentials; back to purity, back to simplicity.
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.
- 4d ago First seen · 313 lines · 91 tokens per session scan A eb30de4965d6
design-is is a skill published in the GitHub repository skillmds/skillmd (1 stars, last pushed yesterday), licensed MIT. It adds 91 tokens to every session and 4,466 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to design-is, differing in 2 lines, and is treated as a copy.
Other skills, from other repositories
get-context
Mandatory design-brief gate for clarifying the product and outcome. Use before ideation, image-to-code builds, redesigns, or product UI work to clarify missing product information and play back the brief before proceeding.
frontend
Builds, styles, and polishes web UI and UX. Use for any frontend, page, component, styling, layout, animation, or visual-quality task, or when asked to make an interface look or feel a certain way.
designlang-tokens
Use when styling UI for cal.com — references the extracted design system tokens instead of inventing colors, spacing, or typography.
antv-x6-editor
A skill for creating and troubleshooting interactive diagrams with AntV X6, a JavaScript engine for editors made of connected nodes and lines. It supports diagram types such as flowcharts, dependency graphs, entity-relationship diagrams, and organization charts.
antv-infographic
Create beautiful infographics based on given text content. Use when users request to create infographics.
app-screenshot-debug
Drive the running termio app via AppleScript / System Events to reach a UI state (focus the window, click a sidebar project, a terminal pane, a control), capture a pixel-accurate screenshot of just that window, and read it back for visual analysis — for diagnosing layout / spacing / alignment / 'this looks ugly'…
