design

design is a skill for Claude Code from procoders/superpowers-v. It costs 67 tokens per session (1,044 once invoked), scanned A, original, MIT.

A workflow for keeping a project's user interface consistent while adding or changing pages, screens, components, or styles. It uses the project's DESIGN.md file as the record of colours, fonts, spacing, layout, and component rules, and ends with a screenshot check.

In plain words
What is it for?
Use it for interface work in a web or other UI project; skip it for libraries, command-line tools, APIs, and other work with no interface.
Why use it?
It prevents a new interface change from drifting away from the project's existing visual rules.

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.

Security

Grade A, and why

design 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 7d 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Design

Load this only when the change has a user interface. It adds no questions: the brainstorm asks at most one about identity, and only for a new project.

1. DESIGN.md is the one source of the look

The project's look lives in DESIGN.md at the repo root, in Google's open format (https://github.com/google-labs-code/design.md): YAML tokens (colors, typography, spacing, rounded, components) between --- fences, then prose sections in this order: Overview, Colors, Typography, Layout, Elevation & Depth, Shapes, Components, Do's and Don'ts. Put DESIGN.md in the plan's change_set whenever you write it.

  • It exists: follow it. New screens use its tokens and its existing components; a new colour, font or component goes into DESIGN.md first, with its reason, never only into a stylesheet.
  • Existing UI, no DESIGN.md: write it from what is there (CSS variables, theme config, the colours, fonts and spacing the pages actually repeat), exactly as it is. Do not restyle the project; record the current look.
  • New project: write it before the first screen, from the spec's Identity: line and the subject itself (what a real business of this kind looks like, not a generic app). Where the owner left the look to you, say so in Overview.

Components, once. Before writing markup, list the project's existing components and partials (buttons, fields, form rows, cards, tables, page shell, error summary) and build from them. A pattern that would appear a second time becomes one shared component with parameters, and its first copy is replaced by it; never paste markup or a style block from one screen into another. The Components section of DESIGN.md names each shared component and where it lives.

Then run npx @google/[email protected] lint DESIGN.md and fix every error (it checks the structure, token references and WCAG AA contrast). Load the tokens into the app as CSS custom properties, so a style never hard-codes a value.

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.

design is a skill published in the GitHub repository procoders/superpowers-v (42 stars, last pushed yesterday), licensed MIT. It adds 67 tokens to every session and 1,044 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-23.
