What it does

Design System is an agent skill from flornkm/personal-site. How to build UI in this repo — compose classes with cn, use the CSS-variable design tokens (never raw hex/px), reuse the typographic and ui/ primitives, and define variants with cva like the existing components. Use whenever writing or editing a component, styling JSX, or reaching for a primitive that does not yet exist.

Its SKILL.md is about 1.6k 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 tokens, Design systems and React components. It works with Tailwind CSS. The repository describes itself as: Florians personal site.

When your agent uses it

  • Editing a component
  • Reaching for a primitive that does not yet exist

Example prompts

  • “/design-system”

Workflow steps

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

  1. Confirm it's missing — read src/components/ui first; reuse/extend if something close exists.
  2. Match the local style — study button.tsx: cva for variants, cn(..., className) merge, forwardRef where a ref is useful (see link.tsx)…
  3. Write it in src/components/ui/.tsx by hand. Keep it small and composable; expose cva variants only if there are real variants.
  4. Use tokens and cn throughout — no raw colors, no inline style for what Tailwind expresses.
  5. Only reach for a third-party headless lib if the primitive is genuinely complex (focus trapping, positioning) and nothing comparable…

What it can do on your machine

Read from SKILL.md and the folder at commit cbc0e20. 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).

    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 1.6k tokens when it runs. Until then it costs about 86 tokens; SKILL.md has 671 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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 671 words (~1,615 tokens).

“This is a TanStack Start + Tailwind v4 site with a handrolled component layer and CSS-variable design tokens. There is no shadcn, no Base UI/Radix, no component CLI — primitives are written by hand in this repo. Stay inside the…”

With the skills CLI, run `npx skills add flornkm/personal-site --skill design-system -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/design-system, .gemini/skills/design-system, .github/skills/design-system and .opencode/skills/design-system in your project.

What does Design System need to run?

SKILL.md names no scripts, command-line tools or credentials: Design System is instructions for the agent only.

Does Design System access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Design System safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
