" Vibe coding " or AI-assisted development carries the risk of introducing " hallucinated " vulnerabilities or insecure coding patterns that the AI learned from public (and potentially flawed) repositories. The most responsible control is to implement a rigorous, human-led " security checklist " for code reviews. This ensures that every line of AI-generated code is checked for common flaws like SQL injection or hardcoded credentials. Prompting the AI to check its own code (Option C) is unreliable because the model may suffer from the same biases or logic errors that created the code in the first place.
