Key Points
- A Qiita post introduces a free CLI tool that performs a fast (30-second) security scan on AI-generated code to catch obvious issues before committing.
- The article argues that these quick scans can create a false sense of safety because AI models may reproduce common vulnerabilities learned from public repositories.
- It highlights a layered Japanese-style workflow: automated scan first, then manual review of flagged parts, plus a separate human-only review for sensitive areas like authentication, payments, or data mutation.
- The author contrasts this with a more common Western pattern of “AI wrote it → scanner approved it → ship it,” warning against treating scanning results as the full review.
- A personal anecdote explains how relying on green automated CI scans led to a real production incident involving insufficient validation in an AI-generated file upload handler.
