About This Assessment

This security assessment was created by Claude Code (an AI assistant from Anthropic) to help users evaluate the safety and trustworthiness of Claude Owl.

This project has been built extensively with Claude Code and, like all software, may contain bugs or security issues. This is open source software - you can review the complete source code, build it yourself, and verify all security claims.

Found a bug or security issue? Please report it on GitHub.

Overall Safety Rating

8.5/10
VERY GOOD

Strong foundational security practices with all critical Electron configuration issues resolved.

✅

Safe for Evaluation

  • ✓ No sensitive data logging (keys, tokens, passwords)
  • ✓ Only accesses Claude config directories
  • ✓ Path validation prevents file system attacks
  • ✓ Security scanning for imported commands
  • ✓ Open source - full code review possible
✅

Production: Ready

  • ✓ Isolated rendering engine (can't access system)
  • ✓ Web security protections enabled
  • ✓ Only opens safe website links
  • ✓ All security vulnerabilities patched

🛡️ Security Protections

System Isolation

  • • Application runs in isolated sandbox
  • • Cannot access files outside Claude directories
  • • Path validation blocks directory traversal
  • • Only opens http:// and https:// links

Data Protection

  • • Zero logging of passwords or API keys
  • • No telemetry or analytics tracking
  • • All data stays on your machine
  • • Never sends files to external servers

Code Safety

  • • Scans imported commands for dangers
  • • Validates hook scripts before saving
  • • Type-safe code (no runtime surprises)
  • • Automated security scanning in CI

Transparency

  • • 100% open source - review all code
  • • Build from source yourself
  • • No obfuscation or hidden behavior
  • • All dependencies publicly auditable

📁 What Data Does Claude Owl Access?

✅ Files Read/Written

File Path Access Purpose
~/.claude/settings.json Read/Write User-level settings
~/.claude.json Read-only Project discovery
{PROJECT}/.claude/settings.json Read/Write Project settings
