At a glance

Explicitly load a design system from the org-level registry at ~/.claude/design-systems/<name/ for the current project.

  • Works in 6 steps: If $0 (name) is missing → Bash(ls… → Verify the folder exists → Read the tokens file → …
  • User says use the Acme design system
  • SKILL.md covers Steps, When to NOT use this skill and Registry format reminder
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Use Design System is an agent skill from bluzir/claude-code-design. Explicitly load a design system from the org-level registry at ~/.claude/design-systems/<name/ for the current project. Use when user says "use the Acme design system", "apply company-x tokens", or similar.

Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Design systems. The repository describes itself as: Claude Design reproduced for Claude Code — HTML decks, prototypes, design systems, animated videos via skills + starters + Chrome DevTools MCP.

When your agent uses it

  • User says use the Acme design system
  • Apply company-x tokens

Example prompts

  • “use the Acme design system”
  • “apply company-x tokens”
  • “/use-design-system”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Bash(ls:*), Bash(mkdir:*), Bash(cp:*)

Workflow steps

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

  1. If $0 (name) is missing → Bash(ls ~/.claude/design-systems/ 2>/dev/null) and show the list, ask which one.
  2. Verify the folder exists
  3. Read the tokens file
  4. Copy to project-level for faster subsequent reads
  5. If ~/.claude/design-systems/$0/preview.html exists, offer to open it for visual reference via /preview…
  6. Report: "Loaded design system $0 — colors, fonts, spacing, radii written to .claude/design-tokens.json. Subsequent /make-deck…

What it can do on your machine

Read from SKILL.md and the folder at commit ce68c84. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Bash(ls:*)
    • Bash(mkdir:*)
    • Bash(cp:*)

    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 json).

    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

Use Design System loads about 563 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 155 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~563

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 155 words (~563 tokens).
