📝 Review Summary

This PR adds a new section "Use Bitwarden SSH agent" to the commit signing documentation. The addition is well-placed and technically sound, fitting naturally between the standard SSH key configuration and keychain storage sections.

✅ Strengths

1. Perfect placement: The new section is logically positioned after standard SSH setup but before keychain configuration, following the document's flow.

2. Follows repository conventions:

   • Uses proper heading hierarchy (### Use Bitwarden SSH agent)
   • Consistent formatting with existing content
   • Proper link formatting with descriptive text

3. Clear and concise: The content is brief but informative, providing essential information without overwhelming detail.

4. Proper external linking: Links to the official Bitwarden help documentation rather than duplicating content.

🎨 Suggestions for Enhancement

While the current implementation is solid, consider these minor improvements:

1. Add context for when to use this option:

   ### Use Bitwarden SSH agent
   
   If you're already using Bitwarden and prefer to manage your SSH keys within your vault, you can use the Bitwarden desktop app as an SSH agent.
   
   Import your SSH key into Bitwarden desktop...

2. Consider adding a tip or note to highlight the benefit:

   :::tip
   
   This approach centralizes your SSH key management within Bitwarden, ensuring keys are only available when your vault is unlocked.
   
   :::

📋 Technical Review

• Grammar & spelling: ✅ No issues found
• Link functionality: ✅ External link format is correct
• Markdown syntax: ✅ Proper heading structure and formatting
• Content accuracy: ✅ Description aligns with Bitwarden's SSH agent capabilities
• Style guide compliance: ✅ Follows repository conventions from CLAUDE.md

🏆 Overall Assessment

This is a clean, focused addition that enhances the documentation by providing users with an additional SSH key management option. The change is minimal, technically accurate, and well-integrated into the existing content structure.

Recommendation: ✅ Approve - This PR is ready to merge as-is, though the minor enhancements above could add value if desired.
