Result of code execution.

Simplified schema optimized for LLM consumption.

Result of a single file download operation.

The response is designed to allow partial success in batch operations.

The errors are standardized using FileOperationError literals for certain recoverable conditions for use cases that involve LLMs performing file operations.

Result from backend write operations.

Base sandbox implementation with execute() as the core abstract method.

This class provides default implementations for all protocol methods. File listing, grep, and glob use shell commands via execute(). Read uses a server-side Python script via execute() for paginated access. Write delegates content transfer to upload_files(). Edit uses a server-side script for small payloads and uploads old/new strings as temp files with a server-side replace for large ones.

Subclasses must implement execute(), upload_files(), download_files(), and the id property.

LangSmith sandbox implementation conforming to SandboxBackendProtocol.

This implementation inherits all file operation methods from BaseSandbox and only implements the execute() method using LangSmith's API.
