What it does
Design System is an agent skill from affaan-m/ECC. アクセシビリティ、レスポンシブネス、テーマ設定、コンポーネント群、トークンを備えた本番環境対応デザインシステムの構築。Figma、Storybook、コンポーネントライブラリ統合。
Its SKILL.md is about 180 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. It works with Storybook and Figma. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.
When your agent uses it
- Tasks that involve Design systems
Example prompts
- “/design-system”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 4eb71d9. 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.
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 System loads about 177 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 40 words of instructions outside code blocks.
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.

When should I use Design System?
Design System fits situations like: tasks that involve Design systems.
How do I install Design System in Claude Code?
Run `npx skills add affaan-m/ECC --skill design-system -a claude-code`. Or copy the skill folder (docs/ja-JP/skills/design-system in affaan-m/ECC) into .claude/skills/design-system in your project. Claude Code loads it when a task matches its description.
