The Difference

Same question, completely different answer.

Without a brief
"Review this code for issues"
"The code looks good overall. Consider adding some error handling and maybe a few more comments."
With security-auditor brief
"Review this code for issues"
"CWE-89 CRITICAL at line 23: SQL injection via string concatenation. Attack vector: attacker injects arbitrary SQL through userId.

Fix: db.query('SELECT * FROM users WHERE id = $1', [userId])"
