Best practices show that including “secure” in prompts can reduce vulnerability density by up to ~43%, and prompting AI as a “security-aware developer” reduces vulnerabilities by ~47–56%.

Rules files:. Many coding assistants support rules files (e.g. Copilot. Claude’s Cursor/Windsurf rules). These files help shape AI-generated code towards specific standards.

Traditional security tools are still vital!. Static analysis (SAST), software composition analysis (SCA), secret scanners, and secure frameworks remain essential, whether or not AI is used. Integrating these in IDEs plus ongoing PR scans reduces risk.

Reports show 25–70 % of AI generated code contains vulnerabilities. Examples of this could be hardcoded secrets or missing auth-checks.

This is my referral link in case someone wants 500 free credits 😁. Meet Manus — your AI agent with its own computer. It builds websites, writes reports, and runs research tasks, even while you sleep.
