Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00072 | $0.01204 |
| Opus 5.5 | $0.00029 | $0.00482 |
| Sonnet 5.5 | $0.00014 | $0.00241 |
| Haiku 4.5 | $0.00007 | $0.00120 |
Grade A, and why
nextjs-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 21d 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.
How it starts
The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Next.js + shadcn/ui
Build an interface with a visual identity that fits its content, audience and task. These are design defaults, not a fixed page recipe; the user's direction and an established design system take precedence.
Choose the visual direction
For a new view or substantial redesign, use frontend-design to choose the typography, palette and composition before building. Preserve a working visual system during smaller edits.
Choose fonts for the product's tone, reading density and language support. Use shadcn/create to choose the component style, body and heading fonts, icon family and theme together. Compare the preview with representative content, then make deliberate choices about type scale, spacing and hierarchy. Neither the default preset nor an unusual font guarantees a good design.
Record the chosen preset, theme, fonts and icon family in the project's design notes; preserve that direction unless the brief changes. References and images are project-specific. Component style and icon family are separate choices; styling.md covers them.
Keep the user's task clear:
- Cut decorative badges, repeated headings, empty marketing claims and helper text that explains the obvious.
- Keep useful status, navigation, explanations and disclosures.
- Use cards, sections and CTAs because the content needs them, rather than filling a template.
- Use brief motion to connect an action with its result, expanded details or active navigation. Reuse existing interaction components; styling.md covers Motion, GSAP and
vercel-react-view-transitionsfor different animation needs. - Reuse the project's icon family. Use
iconswhen sourcing new UI icons, file-type icons or official brand assets; an icon does not automatically replace a clear label.
Use atmosphere when it helps
Grid and dot patterns, soft background lights, gradients, custom shapes, textures, illustrations and video are available design tools. Use them when they suit the brief, strengthen the product's identity or clarify a section. A distinctive background can be the right choice; a quiet page can be too.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

nextjs-shadcn is a skill published in the GitHub repository laguagu/claude-code-nextjs-skills (70 stars, last pushed yesterday), licensed MIT. It adds 72 tokens to every session and 1,204 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
