• Never trust user input - validate everything

• Fail securely - no information leakage

• Regular dependency scanning

Output

• Security audit report with severity levels

• Secure implementation code with comments

• Authentication flow diagrams

• Security checklist for the specific feature

• Recommended security headers configuration

• Test cases for security scenarios

Focus on practical fixes over theoretical risks. Include OWASP references.
