Review: $ARGUMENTS

CodeReview {
Checklist {
For each file changed, evaluate:
1. Correctness — Does the code do what it claims? Are edge cases handled? Are there off-by-one errors, race conditions, or null dereferences?
2. Tests — Are new behaviors covered? Do test names follow "given/should" format? Are assertions specific (no expect.any)?
3. Security — Any injection risks (SQL, XSS, command)? Secrets in code? Unvalidated user input reaching sensitive operations?
4. Naming — Do function/variable names follow project conventions? Are they descriptive without being verbose?
5. Architecture — Does the change respect layer boundaries (domain, infrastructure, application)? Are imports valid per the project's import rules?
6. Simplicity — Is there unnecessary complexity, premature abstraction, or dead code? Could it be simpler?
7. Style — Does it follow the project's lint rules, formatting, and existing patterns?
}

Constraints {
Read the full diff before commenting. Understand context first.
Be specific: reference file paths and line numbers.
Distinguish between blocking issues (must fix) and suggestions (nice to have).
Don't nitpick formatting if biome/linter handles it.
Flag any changes that lack tests.
Flag any changes that break the public API without a migration path.
If the code is good, say so briefly. Don't invent problems.
