Design Systems

What it does

When your agent uses it

• Creating design tokens
• Building component libraries
• Implementing design systems
• Setting up theming architecture

Example prompts

• “/design-systems”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

1. 1Audit existing UI — Inventory current components, colors, typography, and spacing across the product to identify inconsistencies and…
2. 2Define design tokens — Establish primitive tokens (colors, spacing, typography, shadows) as CSS custom properties or a token format (e.g…
3. 3Build foundational components — Create atomic components (Button, Input, Text, Icon) that consume design tokens and expose a clear props…
4. 4Compose patterns and layouts — Assemble atomic components into higher-order patterns (forms, cards, navigation) with documented usage…
5. 5Set up documentation and Storybook — Configure Storybook with stories for every component variant, state, and accessibility annotation…
6. 6Integrate testing and governance — Add visual regression tests (e.g., Chromatic), accessibility linting (e.g., axe-core), and a…
7. 7Ship and iterate — Publish the library as a versioned package, gather consumer feedback, and run regular accessibility and performance…

What it can do on your machine

Read from SKILL.md and the folder at commit 7682ca7. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript and css).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Design Systems loads about 1.8k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 598 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~73

When it runs · the whole SKILL.md, loaded when a task matches

~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
