App Guardrails

What it is

AI writes code fast, but it fails in predictable ways. It skips security checks and ships code that looks right but isn’t. App Guardrails is a Claude skill that asks three quick questions to size up a project, then scales testing and review to match. Eleven safety rules apply no matter what. Small builds stay simple, and serious ones get a real audit before they ship.

Why I built it

I wanted a guaranteed baseline of quality and security in everything I build, even when I don’t spell out every detail.

What I learned

I pushed Claude to research the most common mistakes and security holes in junior-developer and vibe-coded apps, and I kept having it expand on them until the instructions were solid enough to trust running behind the scenes.
