UI Styling
Ohh-889/skyroc
Create beautiful, accessible user interfaces with shadcn/ui components (built on Radix UI + Tailwind), Tailwind CSS utility-first styling, and canvas-based visual designs.
Register AI-generated-looking UI patterns as prohibited rules in the design system.

ban-patternRegister AI-generated-looking UI patterns as prohibited rules in the design system.
Ban Pattern is an agent skill from tsubotax/melta-ui. Register AI-generated-looking UI patterns as prohibited rules in the design system. Use when user says "AIっぽい", "AI臭い", "これ禁止", "このパターンやめたい", "ban this pattern", "add to prohibited", or points out a generic/cookie-cutter UI element.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering Design systems. It works with Tailwind CSS. The repository describes itself as: 人間にも、AIにも、読めるデザインシステム — AI-Ready Design System for Claude Code & Cursor. The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit a44f290. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
npmFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Ban Pattern loads about 1.4k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 265 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

以下を読み込む:

SSOT は design/contracts/rules.json。CI / MCP check_rule / PostToolUse hook はすべて
rules.json を参照する。ここに機械可読ルールを足して初めて「ban → 即 enforcement」が成立する。
prohibited.md は人間向けの解説ミラーであり、enforcement の実体ではない。順序厳守:
design/contracts/rules.json — 機械可読ルールを追加(最優先)rules[] 配列にルールオブジェクトを 1 件追加する。スキーマは design/schemas/rule.schema.json。
detector の選び方(これで自動検出されるか・人手参照に留まるかが決まる):
| detector | いつ使う | 必須フィールド | 例 |
|---|---|---|---|
tailwind-class | 単一の固定クラスを禁止 | pattern(クラス名) | border-l-4, shadow-2xl |
tailwind-class-prefix | 前方一致で複数バリアントを一網打尽 | pattern(接頭辞)。任意値回避経路があれば prefixPatterns も | bg-gradient- |
tailwind-class-segment | クラスを - 分割したセグメント一致(色名等) | matchPatterns(セグメント配列)、pattern: null | purple/violet |

どこが古いかは 3-4 の design:drift がファイル名・数値付きで指摘するので(英語入口の数値整合も検証する)、それに従って直す。components/*.md の禁止事項にも追記する(任意)。npm run design:build # llms.txt / llms-full.txt / metadata/components.json
npm run design:update-showcase # docs/index.html の数値
npm run design:coverage # README の検証カバレッジ表(manual を足すと manual 件数が動く)npm run design:drift # 件数 drift を全部指摘。NO DRIFT になるまで 3-2 を直す

以下のフォーマットで報告する:
## 禁止パターン登録完了
**ルール ID**: `[RULE_ID]`(rules.json に追加 → CI / MCP check_rule / hook で即 enforcement)
**パターン**: [禁止したパターンの説明]
**detector**: `[tailwind-class / -prefix / -segment / manual]`([自動検出 / 人手参照のみ])
**代替**: `[DS準拠の代替]`
### 更新ファイル
- design/contracts/rules.json — 機械可読ルールを追加(SSOT・enforcement の実体)
- foundations/prohibited.md — 人間向け解説に追加([manual の場合: <!-- RULE_ID --> 付き])
- DESIGN.md / README.md / AGENTS.md — ルール件数を N→N+1
- llms / docs/index.html / README カバレッジ表 — 再生成
### 検証
- npm run design:drift — NO DRIFT ✅
- npm run design:check — PASSED ✅
- [auto の場合: npm run design:lint-generated で発火確認]
### サンプル修正
- [修正した箇所のリスト or 「該当なし」]| 問題 | 対処 |
|---|---|
design/contracts/rules.json のスキーマ検証で落ちる | design:check のエラー文に従う。id は大文字スネーク、detector に応じた必須フィールド(tailwind-class→pattern / segment→matchPatterns / manual→pattern:null + contractLint:skip)を確認 |
design:drift が件数 mismatch を出す | 指摘されたファイル・数値の「N ルール」「全ルール(N 件)」を実数に直し、design:build / update-showcase / design:coverage を再実行 |
| manual ルールを足したら orphan 0 検証で落ちる | prohibited.md(または該当 foundations/patterns md)の行末に <!-- RULE_ID --> を付けて参照経路を作る |
| 禁止パターンの Tailwind クラスが特定できない | AskUserQuestion でスクリーンショットや具体例を求める。単一クラスでなく色名なら tailwind-class-segment、接頭辞バリアント群なら tailwind-class-prefix を検討 |
| 既存ルールと部分的に重複する | 既存ルールの拡張(pattern / matchPatterns の追加)で対応するか、新規ルールにするかをユーザーに確認する |

Register AI-generated-looking UI patterns as prohibited rules in the design system. Ban Pattern is an agent skill from tsubotax/melta-ui. Register AI-generated-looking UI patterns as prohibited rules in the design system.
Ban Pattern fits situations like: user says AIっぽい; ban this pattern; add to prohibited; points out a generic/cookie-cutter UI element.
Run `npx skills add tsubotax/melta-ui --skill ban-pattern -a claude-code`. Or copy the skill folder (skills/ban-pattern in tsubotax/melta-ui) into .claude/skills/ban-pattern in your project. Claude Code loads it when a task matches its description.
Run `npx skills add tsubotax/melta-ui --skill ban-pattern -a codex`. Or copy the skill folder (skills/ban-pattern in tsubotax/melta-ui) into .agents/skills/ban-pattern in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add tsubotax/melta-ui --skill ban-pattern -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ban-pattern, .gemini/skills/ban-pattern, .github/skills/ban-pattern and .opencode/skills/ban-pattern in your project.
Going by SKILL.md and its folder, Ban Pattern needs the command-line tools its instructions call (npm).
SKILL.md contains no URLs. Its commands use npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Ban Pattern is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Ban Pattern: UI Styling (Ohh-889/skyroc, 795 stars), Design System (Ohh-889/skyroc, 795 stars), Creative Tim UI Blocks (creativetimofficial/ui, 12k stars) and Scalar Design System (scalar/scalar, 16k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
