shep: Skill for Claude Code

.claude/skills/shadcn-ui/SKILL.md

shadcn-ui is a skill for Claude Code from shep-ai/shep. It costs 74 tokens per session (10,384 once invoked), scanned A, original, MIT.

A guide to shadcn/ui, a collection of accessible React interface components that developers add and customize in their own project. It covers setup, Tailwind CSS styling, Radix UI, and common components such as forms, dialogs, tables, and menus.

In plain words
What is it for?
Use it when setting up shadcn/ui, adding buttons, inputs, cards, dialogs, dropdowns, navigation, tables, or notifications, or building styled forms and layouts in a TypeScript React or Next.js project.
Why use it?
It gives consistent implementation patterns for building user interfaces without figuring out each component's setup and accessibility details from scratch. It also covers form validation with React Hook Form and Zod.

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-ui 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.

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.
