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

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.

Use Cases
- Identify security vulnerabilities like SQL injection and cross-site scripting
- Surface performance bottlenecks and logic errors before deployment
- Categorize findings by severity to prioritize critical fixes first
- Apply suggested code examples to resolve style and syntax violations
Known Limitations
- Cannot execute code to find runtime-only bugs. - Limited context on very large monorepos (better results on specific diffs). - May not catch violations of private/internal proprietary libraries.
