sensitive-content-scanner

To scan files for sensitive content before sharing a repository, you can apply regex-based pattern matching to detect and flag credentials, personal identifiers, and private URLs across your project folders and configurations.

Data sanitization for code and configuration files is the process of detecting sensitive content like credentials and local paths, then replacing them with placeholders to prevent accidental data leakage when publishing.

Regex-based sensitive content detection works by applying predefined and customizable regular expression patterns to scan datasets and flag private URLs, personal identifiers, and embedded credentials.

You can customize sensitive content scanning rules for your local environment by creating a personal context file at ~/.claude/sensitive-content-context.md to tailor the regex detection patterns to your specific project needs.

Sensitive content scanning works with pre-publish checks on local machines by scanning repositories, project folders, and shared configurations to flag sensitive data and provide actionable sanitization guidance before export.

Regex pattern matching can detect credentials, personal identifiers, private URLs, and local paths in configuration files, helping prevent accidental leakage when sharing code or datasets.
