Claude Code produces some of the strongest AI-written code available, often cleaner than a hand-rolled first draft. The point of a scan is not that the code is bad. It is that security review is a separate job, and an agent focused on making a feature work is not simultaneously auditing it against the ways AI code tends to fail.
What still slips through
- Missing authorization on generated routes, including Broken Object Level Authorization
- Hardcoded secrets in scaffolding, migrations, or config
- Fallback secrets in environment lookups that become predictable in production
- JWTs decoded without verifying, and Supabase access without Row Level Security
We measured this across model generations: the secret-leak rate held roughly flat, because the flaw is a pattern of the task, not a gap in the model. The data is in the Claude models security comparison.

The fastest check
Run a free scan on your repo or live URL for a prioritized, high-signal list with exact file and line, plus an AI rewriter to fix each finding. It is the security pass that pairs naturally with building fast in Claude Code.
Frequently asked questions
Is Claude Code's generated code less secure than other AI tools?
No. We measured this across model generations and the secret-leak rate held roughly flat, because the flaw is a pattern of the task, an agent focused on making a feature work rather than auditing it, not a gap specific to one model.
What does Prbl catch that Claude Code itself won't flag?
Missing authorization on generated routes including BOLA, hardcoded secrets in scaffolding or migrations, fallback secrets in environment lookups, JWTs decoded without verifying, and Supabase access without Row Level Security.
How long does a scan take for a Claude Code project?
A few seconds to a minute depending on repo size. Paste the repo or live URL for a prioritized list with exact file and line, plus an AI rewriter to fix each finding.
