Review Summary
The PR looks solid, but has one critical security flaw.
Critical
auth.ts:15 — Unsalted MD5 used for passwords.
const hash = crypto.createHash('md5').update(password).digest('hex');
Use Argon2 or bcrypt instead to prevent rainbow table attacks.

About this skill
Run a structured code review on your recent changes without waiting for a teammate. This skill checks for security vulnerabilities (SQL injection, XSS, authentication bypasses), logic errors, edge cases, performance issues, and style violations.
Findings are organized by severity: Critical, Warning, and Suggestion. Each finding includes the file, line number, a description of the issue, and a concrete fix. Use it as a first pass before peer review, or as your only reviewer on solo projects.
