name: code-quality description: Coding style standards, security guidelines, and accessibility requirements. Use when (1) Writing new code, (2) Reviewing code for style/security, (3) Implementing UI/UX features, (4) Addressing security concerns, (5) Ensuring accessibility compliance. Covers naming conventions, formatting, security best practices (no secrets/PII), accessibility standards (semantic HTML, keyboard nav), and responsive design.

Code Quality Standards

Coding Style

• Naming: camelCase for vars/functions; PascalCase for classes/types
• Formatting: 4-space indentation; target ≤80 chars (wrap thoughtfully)
• Comments: Meaningful, current; delete stale comments
• Security: Never log secrets/PII; validate inputs; least privilege by default
• Errors/Logs: Explicit error types; structured logs by level; actionable messages

Accessibility & UX Quality

• Favor semantic roles/labels; keyboard nav and focus order must work
• Include responsive checks at 375, 768, 1024, 1440 with notes/screenshots
• Use deterministic test IDs; avoid brittle CSS/XPath

Security & Compliance Guardrails

• No real credentials in code, tests, or screenshots
• Use test accounts/fixtures; redact secrets

這個 Skill 整體質量良好，能有效指導程式碼質量工作。優點是結構清晰、覆蓋全面，能在多個開發場景中發揮作用。不過內容相對簡略，引用了許多實用指南但參考文件缺失，需要進一步補充完善才能發揮全部價值。
