Quick Start

1. Obtain a GitHub Personal Access Token (instructions).

   Note: To avoid issues during analysis, ensure you grant all available permissions to the token. Insufficient permissions may cause errors or incomplete results.

2. Initialize your API key:

   exc key
   

3. Run your first analysis:

   exc analysis owner/repo

Detailed Command Reference

1. API Key Management

• Set or update your GitHub API key:

  exc key
  

• Reset (delete) your API key:

  exc key --reset
  

• Storage:
  • Linux: ~/.exc/apikey.sec (permissions: 0600)
  • Windows: %USERPROFILE%\.exc\apikey.sec

2. Repository Analysis

• Analyze repository health, stats, and contributors:

  exc analysis owner/repo
  

  • Shows description, stars, forks, languages, top committers, contributors, issues, and PRs.

3. User Analysis

• Profile a GitHub user:

  exc user-a username
  

  • Displays user info, activity, and top repositories.

4. Secret Scanning

• Scan recent commits for secrets:

  exc scan-secrets owner/repo -l 20
  

  • Detects AWS keys, GitHub tokens, SSH keys, and generic API keys in the last N commits.
• Deep scan for secrets in files and commits:

  exc advanced-secrets owner/repo -l 30
  

  • Scans all files and recent commits for a wide range of secret patterns.

5. File History

• Show commit history for a specific file:

  exc file-history owner/repo path/to/file.py
  

  • Lists commit messages, authors, dates, and links for the file.

6. Dork Scan

• Search public GitHub code for sensitive patterns:

  exc dork-scan "dork query"
  

  • Supports advanced queries, file extension and filename filters.

7. Contributor Impact

• Estimate contributor impact:

  exc contrib-impact owner/repo
  

  • Ranks contributors by code additions/deletions.

8. Security Scoring

• Evaluate repository security posture:

  exc security-score owner/repo
  

  • Checks for branch protection, code scanning, dependabot, security.md, and more.

9. Commit/PR Anomaly Detection

• Detect suspicious commit/PR activity:

  exc commit-anomaly owner/repo
  

  • Flags risky commit messages and patterns.

10. User Anomaly Detection

• Detect unusual user activity:

  exc user-anomaly username
  

  • Highlights abnormal event timing or frequency.

11. Content & Workflow Auditing

• Audit repository documentation and policies:

  exc content-audit owner/repo
  

  • Checks for LICENSE, SECURITY.md, CODE_OF_CONDUCT.md, CONTRIBUTING.md, and README quality.
• Audit GitHub Actions/CI workflows:

  exc actions-audit owner/repo
  

  • Reviews workflow files for security risks and best practices.

API Key Management

• Your GitHub token is required for all API operations.
• The token is stored securely and never transmitted except to GitHub.
• If you lose or wish to rotate your token, use exc key --reset.

---

Troubleshooting

• API Rate Limits: If you hit GitHub API rate limits, wait and retry later. Use a personal access token with sufficient permissions.
• Missing Output or Slow Results: Large repositories or high API usage may cause delays. Try reducing the number of results or commit range.
• Color Output Issues: If you do not see colored output, ensure your terminal supports ANSI colors (e.g., use modern terminals on Windows or Linux).
• Permission Errors: Ensure you have write access to your home directory for API key storage.
