Safe Repository Check

Context

Security audit for sensitive data in repository. Check for credentials, API keys, company-specific information, and PII.

Modes

• Default (full-scan): scans all git-tracked files plus history. Use for periodic audits or first-time repo review.
• --diff: scans only staged + unstaged changes (git diff + git diff --cached). Use before commit or when called from review / ship workflows. Fast, no false positives from pre-existing files.

Workflow

Default (full-scan)

1. Run bash scripts/scan-secrets.sh to scan all tracked files for credential patterns
2. Check for sensitive tracked files by name: .env* (except .env.example), *.pem, *.key, *_rsa*, *secret*, *credential*
3. Analyze git history for removed secrets: git log --all --full-history -- "*.env" "*.pem" "*.key" "*secret*" "*credential*"
4. Review .gitignore for proper patterns
5. Report findings (see assets/report-template.md)

--diff mode

1. Compute changed files: git diff --name-only HEAD + git diff --name-only --cached
2. Scan only those files with the regexes in scripts/scan-secrets.sh (grep them directly) plus the filename checks above
3. Skip history analysis (not relevant for in-flight changes)
4. Report findings scoped to changed files only

Rules

• Only check git-tracked files (git ls-files) - ignore local configs
• Check current tracked files AND git history
• Filter false positives: minified JS, node_modules, test fixtures, docs
• Verify .gitignore covers sensitive patterns
• Report tracked files with secrets and historical commits
• Never output actual secret values in report

Error Handling

• If git history scan is slow → limit to last 100 commits with git log --oneline -100
