Module cli_download 

CLI download and management utilities Automatic Claude Code CLI download and management

This module provides functionality to automatically download and manage the Claude Code CLI binary, similar to Python SDK’s bundling approach.

Download Strategy

1. First, check if CLI is already installed (PATH, common locations)
2. If not found, check the SDK’s local cache directory
3. If not cached, download from official source and cache locally

Cache Location

• Unix: ~/.cache/cc-sdk/cli/
• macOS: ~/Library/Caches/cc-sdk/cli/
• Windows: %LOCALAPPDATA%\cc-sdk\cli\

Feature Flag

The download functionality requires the auto-download feature (enabled by default). To disable, use default-features = false in your Cargo.toml.
