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.

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 | $0.00077 | $0.00945 |
| Opus 5 | $0.00039 | $0.00473 |
| Sonnet 5 | $0.00015 | $0.00189 |
| Haiku 4.5 | $0.00008 | $0.00094 |
Grade A, and why
frontend-design 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 today.
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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
What ships with it
3 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.

frontend-design is a skill published in the GitHub repository zebbern/termstack (5 stars, last pushed 4mo ago), with no licence file. It adds 77 tokens to every session and 945 once invoked, about $0.0004 per session on Opus 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 2026-09-03.

ranui
Use when building UI with the ranui web-component library (elements like , , , , ) or its fluent DOM builder (ranui/builder — Div/View/Span/signal/createEffect/EventManager). Covers the import map, the full element inventory, conventions, accessibility, and where the authoritative API reference lives.
dile-components
Use when building or modifying UI with the Dile Components library (@dile/ui, @dile/crud, @dile/editor, @dile/utils, @dile/lib, @dile/iconlib, @dile/icons) — a framework-agnostic, Lit-based web component catalog. Trigger when installing/importing dile- custom elements, using tags like , , , building CRUD screens…
ui-design
先推理，后构建。 AI 最大的设计问题是跳过对业务逻辑和用户意图的深度分析，直接套用万能模板：居中 Hero 布局、饱和度过高的蓝紫渐变、无脑的 Inter 全家桶、以及满屏的毛玻璃卡片。这不叫设计，这叫向默认值妥协[cite: 3]。.
awesome-design-md
Create a DESIGN.md style baseline BEFORE building UI. Use FIRST when no design draft exists — installs a proven visual style, then invoke frontend-design to implement. For borrowing a known product style, getting consistent typography/colors/spacing, or needing a fast visual starting point.
design-system
Document and define UI design system tokens, components, and guidelines.
frontend-ui-engineering
Builds production-quality UIs. Use when building or modifying user-facing interfaces. Use when creating components, implementing layouts, managing state, or when the output needs to look and feel production-quality rather than AI-generated.
