implementing-ui

implementing-ui is a skill for Claude Code, Codex from careerchain-ys/stdd. It costs 98 tokens per session (4,461 once invoked), scanned A, original, Apache-2.0.

A guide for building user interfaces, including admin screens, tables, forms, validation, and layouts that adapt to different screen sizes. It tells the agent to follow the project’s requirements and technical design documents.

In plain words
What is it for?
Building admin dashboards, list and table views, React Hook Form forms, validation rules, responsive layouts, and mobile-friendly components.
Why use it?
It gives consistent rules for screen structure, form behavior, field validation, displayed values, and mobile support instead of leaving those decisions to each implementation.

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

implementing-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 4d 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.

UI実装スキル

対象プロジェクトにおけるUI実装の包括的ガイド。

重要: 仕様書の参照

⚠️ UI実装を開始する前に、必ず以下の仕様書を確認すること:

  1. REQUIREMENTS.md - 画面の目的・ユースケースを理解
  2. TECH_DESIGN.md - 技術設計・型定義、および「画面項目定義」セクション(画面 feature は必須・非画面 feature は省略)の項目詳細・バリデーションルール・表示形式

TECH_DESIGN.md の画面項目定義セクションがある場合:

  • フォーム項目名・データ型は定義に従うこと
  • バリデーションルールは定義通りに実装すること
  • 表示形式(日付フォーマット、通貨など)は定義に従うこと
  • 選択肢の値・表示テキストは定義通りに実装すること

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.
