    Common Pitfalls

    AI code suggestions introduce security vulnerabilities
    Mitigation: Run SAST on AI-generated code. Require security review for AI suggestions. Maintain blocklist of unsafe patterns.
    AI review comments too verbose, developers ignore them
    Mitigation: Tune AI to provide concise feedback. Prioritize critical issues. Limit to 5 comments per PR. Human review still required.
    AI training data includes proprietary code, legal risk
    Mitigation: Use enterprise AI tools with data privacy guarantees. Review AI provider terms. Audit AI output for copied code.
