PR Review Complete ✅

I've thoroughly reviewed this documentation PR for the settings.sh script. Here's my comprehensive feedback:

✅ Code Quality & Best Practices

• Excellent documentation structure: The changes follow the established pattern perfectly, adding both Quick Start usage and detailed Scripts section documentation
• Bilingual approach: Properly maintains the English/Japanese format consistent with the repository's style
• Clear and actionable: The documentation clearly explains what the script does and its requirements

✅ Accuracy & Completeness

• Script verification: Confirmed settings.sh exists at /home/runner/work/dotfiles/dotfiles/settings.sh:1-11 and contains exactly what's documented
• Accurate description: The documentation correctly states it "disables press-and-hold for keys in favor of key repeat"
• Important warning included: Properly mentions the system restart requirement
• Logical placement: Added in the correct sequence (after ./link.sh) in Quick Start section

✅ Repository Conventions

• Follows CLAUDE.md guidelines: Matches the established documentation patterns and conventional commit format (docs:)
• Consistent formatting: Uses the same structure as other script documentation (install.sh, link.sh)
• Proper section organization: Maintains the logical flow of the README structure

✅ Security & Performance

• No security concerns: Documentation-only changes with no functional impact
• Safe script reference: The referenced settings.sh uses standard macOS defaults write command safely
• No performance impact: Pure documentation addition

✅ Testing Considerations

• Documentation testing: As noted in the PR description, the author verified README.md renders correctly
• No functional testing needed: Since this is documentation-only, no code changes require testing
• Script accuracy verified: The documented behavior matches the actual script implementation

Minor Suggestions for Excellence

While the PR is solid as-is, here are some optional enhancements for future consideration:

1. Enhanced Quick Start context: Could mention this is optional (since other scripts are required) - something like # Configure macOS system settings (optional)

2. Expanded script description: Could mention this is specifically for development workflow optimization in the Scripts section

Summary

This is a high-quality documentation PR that:

• ✅ Accurately documents existing functionality
• ✅ Follows all repository conventions and patterns
• ✅ Maintains consistency with existing documentation style
• ✅ Provides clear, actionable information for users
• ✅ Has zero security, performance, or functional risks

Recommendation: Approve and merge 🚀
