Claude Code Review

VERDICT: APPROVE

SUMMARY: This PR changes the version flag shorthand from -V to -v to align with common CLI conventions where lowercase -v is the standard version flag. The change is cosmetic and introduces no security or correctness issues. The verification shows no conflicts with existing options.

FINDINGS: None

---

Verification Details:

I checked the following potential issues and found no problems:

1. Flag Collision Check: Searched the entire file for existing -v option definitions. Found only one other use on line 172 (-v, --verbose in the check command), but this is scoped to that specific command and does not conflict with the global -v, --version flag defined on line 137. Commander.js correctly handles command-specific flags separately from global flags.

2. Breaking Change Assessment: This change alters the CLI interface by removing -V as a shorthand. However:

   • The long form --version remains unchanged (backward compatible)
   • Users typing -V will get an "unknown option" error instead of the version (degradation, not a security issue)
   • The new -v shorthand matches widespread CLI conventions (git, npm, docker all use -v)
   • This is a UX improvement, not a security regression

3. Input Validation: The VERSION constant comes from the imports (line 9). No user input is involved in this change.

4. Code Logic: The change only affects the argument passed to .version(). The Commander.js library handles this safely.

No security or correctness mitigations were needed as this is a pure interface change with no execution logic modifications.
