This change makes the Claude Code SDK package optional, preventing installation failures for users who don't need Claude Code functionality. Changes: - Added @anthropic-ai/claude-code to optionalDependencies in package.json - Implemented lazy loading in language-model.js to only import the SDK when actually used - Updated documentation to explain the optional installation requirement - Applied formatting fixes to ensure code consistency Benefits: - Users without Claude Code subscriptions don't need to install the dependency - Reduces package size for users who don't use Claude Code - Prevents installation failures if the package is unavailable - Provides clear error messages when the package is needed but not installed The implementation uses dynamic imports to load the SDK only when doGenerate() or doStream() is called, ensuring the provider can be instantiated without the package present.
