Code Scanning: How to Detect Bugs and Code Quality Issues. Here's the short version.

Code scanning is an umbrella term for automated inspection of source or artifacts. This article separates static quality scans, security-focused SAST, dependency scanning, secret scanning, and dynamic testing — and explains triage, remediation, and re-scanning.

Types of scanning. Static application security testing (SAST) — source patterns for vulnerabilities. General static analysis — bugs, smells, complexity, maintainability. Dependency scanning — known CVEs in packages (e.g. Dependabot alerts). Secret scanning — committed tokens and keys.

Scanning pull requests vs full repositories. PR scans focus on diffs for fast feedback. Full-repository scans baseline legacy debt and find issues in unmodified files.

Triage and remediation workflow. First, run scan and export or view severity-ranked findings. Second, assign owners for Critical and High items. Third, fix or document justified suppressions. Fourth, re-scan to verify closure.

Want to find these issues in your own code? Connect your GitHub repository to CodeInspector. You'll get findings with the file, line, severity, and a recommended fix, plus HTML and PDF reports for your team. Start free at codeinspector.app.
