geeklego: Skill for Claude Code

.claude/skills/component-builder-v2/SKILL.md

component-builder-v2 is a skill for Claude Code from GeekyAnts/geeklego. It costs 257 tokens per session (7,521 once invoked), scanned A, original, MIT.

A guide for building React components that follow the GeekLego v2 design system, using ShadCN, Tailwind, and Radix UI patterns. React is a library for building web interfaces; these tools provide shared styling and behavior rules.

In plain words
What is it for?
Use it to create or scaffold buttons, dialogs, popovers, comboboxes, commands, and other React interface components.
Why use it?
It keeps new components consistent with the existing design system and its accessibility and code-structure conventions.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md.

This is GeekyAnts/geeklego's own configuration. It tells Claude Code how to work on geeklego itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything geeklego configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { cn } from "../lib/cn";.

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

component-builder-v2 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 10d 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.

GeekLego Component Builder (v2 — 2-tier ShadCN/Radix)

You generate v2 components: the ShadCN pattern (cva + cn + forwardRef + Radix primitives), styled with standard semantic Tailwind utilities (bg-primary text-primary-foreground), on geeklego's primitive palette. No component-token tier, no atom/molecule/organism folders, no memo(forwardRef), no hand-rolled a11y where Radix provides it.

Read before every session

File Why
CLAUDE.md (repo root) The v2 rules: 2-tier model, ShadCN pattern, Radix-first, hard rules. Authoritative.
components/v2/Button/ The canonical reference for a simple component. Mirror its shape exactly: Button.tsx, button-variants.ts, Button.types.ts, Button.stories.tsx, and components/v2/lib/cn.ts.
components/v2/Dialog/, Popover/ The shipped references for a compound component built on a Radix primitive. When you build anything with slots + a Radix behavioral primitive, read the real Dialog/Popover first — they're the worked, in-repo version of the pattern.
components/v2/Combobox/, Command/ The shipped reference for the trickiest recipe — Popover + cmdk. Read these when building a combobox/autocomplete/command-palette.
design-system/v2/semantics.css The standard semantic token set + how @theme inline registers utilities + the --ext-* custom-variant block. Know what semantics exist before styling.
references/radix-primitive-map.md Before building anything interactive — the lookup for "does Radix already provide this?"
references/composition-example.md The why behind the compound-on-Radix pattern (what the old 3-tier code hand-rolled, and how Radix replaces each piece). Read alongside the real Dialog above.

Changes

What this file has done since we first saw it

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.
