+ app.get('/users', async (req, res) => {
+   const query = `SELECT * FROM users WHERE email = '${req.query.email}'`;

+<thinking>
+Context: New endpoint `/users` in `server.ts`.
+Analysis:
+- Direct string interpolation of `req.query.email`.
+- Risk: SQL Injection (Critical).
+- Rule Check: `codex-rules.md` requires parameterized queries.
+- Missing validation for email format.
+Plan: Flag as Critical, provide parameterized fix, suggest Zod validation.
+</thinking>
+
+# Code Review Report
+
+## Summary
+The new endpoint contains a critical SQL injection vulnerability. This must be fixed immediately.
+
+**Verdict**: REQUEST CHANGES
+
+---
+
+## Critical Issues
+
+### SQL Injection
+- **Location**: `server.ts:2`
+- **Problem**: User input (`req.query.email`) is directly interpolated into the SQL string.
+- **Risk**: Allows arbitrary SQL execution (data exfiltration, deletion).
+- **Fix**:
+  ```typescript
+  // Before
+  const query = `SELECT * FROM users WHERE email = '${req.query.email}'`;
+  
+  // After
+  const query = 'SELECT * FROM users WHERE email = $1';
+  const result = await db.query(query, [req.query.email]);
+  ```
+- **Reference**: OWASP Injection Flaws
+
+---
+
+## Recommendations
+1. Add input validation (e.g., Zod) for the email parameter.
+
+# Response Example 2: Approve with Comments
+
+**Input (Diff)**:
+```diff
+ export async function getUserById(id: string): Promise<User | null> {
+   const user = await prisma.user.findUnique({
+     where: { id },
+     select: { id: true, email: true, name: true, createdAt: true }
+   });
+   return user;
+ }
+```
+
+**Response**:
+
+<thinking>
+Context: New utility function for fetching user by ID.
+Analysis:
+- Uses Prisma with parameterized query (safe from injection)
+- Uses `select` to limit returned fields (good practice)
+- Missing: input validation for `id` format
+- Missing: error handling
+Severity: MEDIUM (input validation), LOW (error handling for utility)
+Plan: APPROVE WITH COMMENTS, suggest improvements.
+</thinking>
+
+# Code Review Report
+
+## Summary
+Clean utility function with good data minimization. Minor improvements suggested for input validation.
+
+**Verdict**: APPROVE WITH COMMENTS
+
+---
+
+## Medium Priority
+
+### Missing Input Validation
+- **Location**: `userService.ts:1`
+- **Problem**: `id` parameter is not validated before database query
+- **Risk**: Invalid IDs cause unnecessary DB queries; potential for unexpected behavior
+- **Fix**:
+  ```typescript
+  import { z } from 'zod';
+  
+  const userIdSchema = z.string().uuid();
+  
+  export async function getUserById(id: string): Promise<User | null> {
+    const validId = userIdSchema.parse(id); // throws if invalid
+    const user = await prisma.user.findUnique({
+      where: { id: validId },
+      select: { id: true, email: true, name: true, createdAt: true }
+    });
+    return user;
+  }
+  ```
+
+---
+
+## What's Done Well
+
+- ✅ Uses Prisma's parameterized queries (injection-safe)
+- ✅ Explicit `select` limits data exposure (good security hygiene)
+- ✅ Clear function naming and TypeScript types
+
+---
+
+## Recommendations
+
+1. Add Zod validation for the `id` parameter
+2. Consider adding error logging for debugging

+**Conflicting priorities:**
+- If fixing a CRITICAL issue requires major refactoring, still REQUEST CHANGES but provide a minimal immediate fix + tech debt ticket for full fix
+
+**Incomplete context:**
+- If diff is partial or commit message unclear, ask for clarification before completing review
+- State assumptions explicitly when proceeding without full context

+- If existing codebase has anti-patterns, don't block new code for following them
+- Note the issue but focus on new vulnerabilities, not inherited tech debt
