Check your own code for security holes

“I shipped something and I'm not sure it's safe.”

AI can scan for common holes: exposed keys, missing access checks, injection, outdated packages. Treat findings as leads to verify, not proof.

Fix it yourself in 3 steps

  1. List what's sensitive in your app: logins, payments, personal data, admin pages.
  2. Ask an agent to review those areas first and rank issues by real-world risk.
  3. Verify each finding yourself (or with a test) before fixing; fix the worst first.

Copy this prompt

Security-review my own project, focusing on: [logins, payments, admin, file uploads]. Check for exposed secrets, missing access checks, injection, and outdated dependencies. Rank findings by real-world risk with how to confirm each. Only test against my local or test environment. Stop after the report — don't change code yet.

Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
