這個 Skill 是什麼?

把介面任務轉成可觀察的無障礙驗收條件。

可以做什麼?何時適合使用?

  • 改善表單標籤與錯誤恢復
  • 檢查對話框焦點返回
  • 規劃螢幕閱讀器驗收
  • 檢查色彩對比、縮放、reflow 與減少動態效果

如何使用

  1. 提供介面、使用者任務與支援環境
  2. 先列原生 HTML、ARIA 與鍵盤行為要求
  3. 提出修改及人工驗收矩陣,區分未測項目
  4. 逐項檢視語意結構、導覽、表單、dialog、焦點、鍵盤與螢幕閱讀器輸出

使用前你需要準備

  • 介面程式與設計目標
  • 目標裝置和操作方式

你可以替換:

[component]、[screen size]

環境與相依需求

  • 提供元件程式與瀏覽器/輔助科技範圍;完整使用時保留來源 references。

使用範例與 Prompt

以下是 2lus 撰寫的示範需求;請替換為你有權處理的檔案與專案,不代表已執行或保證結果。

入門

檢查這個登入表單的 label、錯誤關聯與鍵盤順序;先列問題,不要執行瀏覽器。

實務

為刪除確認 dialog 設計初始焦點、Escape、可見關閉與焦點返回的人工步驟。

進階

依附件元件設計 WCAG 2.2 驗收矩陣,涵蓋縮放、減少動態效果及兩種螢幕閱讀器;標記證據缺口。

實用提醒

  • 以原生控制項優先;ARIA 不會自動提供鍵盤操作。
  • 自動檢測可找出部分缺陷;仍需人工檢查鍵盤、閱讀順序與輔助科技操作。

限制與注意事項

  • 自動掃描或程式審查不能宣稱 WCAG 完整合規。

安全注意事項

  • 只使用去識別化表單資料;讀取來源不代表授權執行外部工具。

使用與設定

此條目不提供已確認的通用安裝指令;請依官方文件與 Agent 版本操作。

Resource type

Skill

How is this different from similar skills?

  • Web Design Guidelines

    Web Design Guidelines reviews overall UI/UX; Web Accessibility examines WCAG, ARIA, keyboard behavior and assistive-technology evidence.

Documented capabilities

These are operations described upstream, not permissions granted or tested by 2lus.

Capabilities not declared here; review the original source.

What is this skill?

Turn interface tasks into observable accessibility acceptance criteria.

Use cases and when to use it

  • Repair form labels and recovery
  • Review dialog focus restoration
  • Plan screen-reader acceptance
  • Review contrast, zoom, reflow, and reduced motion

How to use it

  1. Provide components, tasks and supported environments
  2. Specify native HTML, ARIA and keyboard behavior
  3. Propose changes and a manual evidence matrix
  4. Inspect semantics, navigation, forms, dialogs, focus, keyboard use, and screen-reader output

What you need

  • Interface code and design goals
  • Target devices and interaction methods

You can replace:

[component], [screen size]

Environment and dependencies

  • Supply component code and browser/AT scope; retain upstream references.

Usage and prompt examples

These example requests were written by 2lus. Substitute files and projects you may use; examples are not executed results or guarantees.

Beginner

Inspect this login form for labels, error associations and tab order; report findings without launching a browser.

Practical

Draft manual checks for initial focus, Escape, visible dismissal and focus restoration in this deletion dialog.

Advanced

Create a WCAG 2.2 evidence matrix for these components covering zoom, reduced motion and two screen readers; flag untested conditions.

Tips

  • Prefer native controls; ARIA alone provides no keyboard interaction.
  • Automated checks find only some defects; manually review keyboard use, reading order, and assistive technology.

Limitations

  • Code review or automated scanning cannot establish full WCAG conformance.

Security notes

  • Use anonymized form data; source access does not authorize external execution.

Usage and setup

No verified universal installation command is provided for this entry. Follow the official documentation for your agent version.

Supported agents
