🏗️ Architecture Overview

Dual Implementation Strategy

  • TinyGo Implementation: Security-focused, minimal attack surface (~2MB)
  • Rust Implementation: Performance-optimized, feature-rich (~8MB)
  • Automatic Selection: Smart selection based on operation characteristics

Security Features

  • WebAssembly Sandboxing: Complete isolation through WASM runtime
  • Capability-Based Security: Only explicitly granted file system access
  • Path Validation: Automatic protection against path traversal attacks
  • Preopen Directories: Restricted access to specified directory trees
