## 🚨 Critical Issues & Bugs
None detected.

## 💡 Suggestions & Best Practices

• rss/index.html: The new URL string ('https://mcp.tokenbel.info/mcp') is hardcoded three separate times within the same component (display text, clipboard function, and href attribute). If you are using a frontend framework like Alpine.js (which the @click syntax suggests) or Vue, it is highly recommended to assign this URL to a data variable. This prevents "magic strings" and ensures you only have to update it in one place next time.

<!-- Example using Alpine.js -->
<div x-data="{ mcpUrl: 'https://mcp.tokenbel.info/mcp', copied: null }">
  <code x-text="mcpUrl"></code>
  
  <button @click="navigator.clipboard.writeText(mcpUrl); copied = 'mcp'; setTimeout(() => copied = null, 2000)">
    Copy
  </button>
  
  <a :href="mcpUrl" target="_blank" rel="noopener">
    Open
  </a>
</div>

## 📊 Final Assessment

• Rating: Good
• Reason: The PR is a clean, low-risk update that effectively accomplishes its goal without introducing bugs or security issues. Implementing the suggested variable extraction would be a nice maintainability improvement, but it does not block this change from being merged.
