A design review tool that evaluates a website or interface against Dieter Rams' ten principles of good design. It produces evidence-based scores, a verdict, and a handoff plan for creating, refining, or redesigning the work.

Use it to audit an existing design, score each principle, document supporting evidence, and prepare a make-plan request for the next design changes.

It gives a structured way to find usability and visual design problems instead of relying only on subjective feedback.

Token cost

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	$0.00091	$0.04466
Opus 5.5	$0.00036	$0.01786

Security

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 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.

Origin

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-plan directly

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.

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.
