.agents/skills/shadcn/SKILL.md

shadcn is a skill for Claude Code, Codex from dinhtungdu/tangerine. It costs 90 tokens per session (4,411 once invoked), scanned A, a copy of shadcn, MIT.

A guide and toolset for shadcn/ui, a system that adds interface components as source code to a project.

In plain words
What is it for?
Use it to add, search, repair, debug, style, and combine shadcn/ui components and presets.
Why use it?
It helps locate the right project configuration and documentation, especially when the project is a monorepo—a repository containing multiple related projects.

Skill for Claude CodeCodex

Written for Claude Code and Codex: allowed-tools in frontmatter, but also agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is dinhtungdu/tangerine's own configuration. It tells Claude Code and Codex how to work on tangerine 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 tangerine configures →

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

shadcn 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 2mo 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.

Origin

This is a copy

How it starts

The opening of the file, as written. The whole thing — 249 lines — stays where its author put it; the contents beside it link to each section on GitHub.

shadcn/ui

A framework for building ui, components and design systems. Components are added as source code to the user's project via the CLI.

IMPORTANT: Run all CLI commands using the project's package runner: npx shadcn@latest, pnpm dlx shadcn@latest, or bunx --bun shadcn@latest — based on the project's packageManager. Examples below use npx shadcn@latest but substitute the correct runner for the project.

Current Project Context

!`f() { local dir="${1:-.}"; if [ -f "$dir/components.json" ]; then npx shadcn@latest info --json -c "$dir"; return; fi; for d in $(find . -maxdepth 3 -name "components.json" -not -path "*/node_modules/*" 2>/dev/null | head -5 | xargs -I{} dirname {}); do npx shadcn@latest info --json -c "$d"; return; done; npx shadcn@latest info --json; }; f`

The JSON above contains the project config and installed components. Use npx shadcn@latest docs <component> to get documentation and example URLs for any component.

Monorepo note: In monorepos, components.json lives in a subdirectory (e.g. web/). The context above auto-detects it by searching up to 3 levels deep. If auto-detect fails or you need a specific workspace, pass -c <path> explicitly: npx shadcn@latest info -c web --json. Never run npx shadcn@latest info from a monorepo root without -c — it will error.

Principles

  1. Use existing components first. Use npx shadcn@latest search to check registries before writing custom UI. Check community registries too.
  2. Compose, don't reinvent. Settings page = Tabs + Card + form controls. Dashboard = Sidebar + Card + Chart + Table.
  3. Use built-in variants before custom styles. variant="outline", size="sm", etc.
  4. Use semantic colors. bg-primary, text-muted-foreground — never raw values like bg-blue-500.

Critical Rules

These rules are always enforced. Each links to a file with Incorrect/Correct code pairs.

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.
