• 🔑 No Token Management - Uses GitHub CLI authentication, no personal access tokens needed
• 🛡️ Privacy by Design - All API calls use your existing gh CLI permissions directly

Command Execution Security 🔒

Robust protection against prompt injections and malicious command execution:

• ⚪ Allowlisted Commands Only - Only pre-approved, safe NPM and GitHub CLI commands are executable
  • NPM: view, search, ping, config, whoami
  • GitHub CLI: search, api, auth, org
• 🛡️ Argument Sanitization - All command arguments are properly escaped to prevent shell injection attacks
• ✅ Pre-execution Validation - Every command is validated against allowed lists before execution
• 🔧 Controlled Environment - Commands run in a secure, cross-platform shell environment with controlled variables
  • Cross-platform shells: Uses /bin/sh on Unix/macOS, cmd.exe or powershell.exe on Windows - minimal, standard shells
  • PowerShell support: Modern Windows environments can optionally use PowerShell with enhanced security
  • Why minimal shells are safe: Avoids user's potentially customized shells with aliases, functions, plugins, or advanced features
  • Controlled variables: Only essential environment variables (PATH, SHELL) are passed, preventing environment-based attacks
  • Platform-specific escaping: Uses appropriate argument escaping for each platform (single quotes on Unix, double quotes for CMD, single quotes for PowerShell)
• 🚫 No Arbitrary Execution - System cannot execute arbitrary shell commands or scripts
• ⏱️ Timeout Protection - All commands have execution timeouts to prevent resource exhaustion
