roche-sandbox 0.4.0

Universal sandbox orchestrator for AI agents — Python SDK

roche-sandbox

Python SDK for Roche -- universal sandbox orchestrator for AI agents.

Requirements

• Python >= 3.10
• Roche CLI on PATH (or Roche daemon running)

Install

pip install roche-sandbox          # SDK only (requires Roche CLI installed separately)
pip install roche-sandbox[cli]     # SDK + auto-download prebuilt CLI binary

If you installed without [cli], you can download the CLI later:

roche-install-cli                  # downloads from GitHub Releases
cargo install roche-cli            # or build from source

Quick Start

from roche_sandbox import Roche

roche = Roche()
sandbox = roche.create(image="python:3.12-slim")
output = sandbox.exec(["python3", "-c", "print('Hello from Roche!')"])
print(output.stdout)  # Hello from Roche!
sandbox.destroy()

Context Manager (auto-cleanup)

with roche.create(image="python:3.12-slim") as sandbox:
    output = sandbox.exec(["echo", "hello"])

Async API

import asyncio
from roche_sandbox import AsyncRoche

async def main():
    roche = AsyncRoche()
    sandbox = await roche.create(image="python:3.12-slim")
    output = await sandbox.exec(["echo", "hello"])
    await sandbox.destroy()

asyncio.run(main())

Configuration

sandbox = roche.create(
    image="python:3.12-slim",
    memory="512m",
    cpus=1.0,
    timeout_secs=600,
    network=False,    # default: AI-safe
    writable=False,   # default: AI-safe
    env={"API_KEY": "secret"},
)

Transport

The SDK auto-detects whether the Roche gRPC daemon is running and connects to it. If the daemon is unavailable, it falls back to invoking the Roche CLI as a subprocess.

You can force CLI mode explicitly:

roche = Roche(mode="direct")

API Styles

The SDK provides two API styles:

• Async-first: AsyncRoche and AsyncSandbox -- native async/await support.
• Sync wrapper: Roche and Sandbox -- blocking equivalents for scripts and notebooks.

Public Exports

from roche_sandbox import (
    Roche, AsyncRoche,
    Sandbox, AsyncSandbox,
    roche_sandbox,                 # decorator
    SandboxConfig, ExecOutput, SandboxInfo,
    Mount, SandboxStatus,
    RocheError, SandboxNotFound, SandboxPaused,
    ProviderUnavailable, TimeoutError, UnsupportedOperation,
)

@roche_sandbox Decorator

The decorator automatically creates and injects a sandbox into your function — no manual lifecycle management needed. Works with both sync and async functions.

from roche_sandbox import roche_sandbox

@roche_sandbox(image="python:3.12-slim")
def run_code(code: str, sandbox) -> str:
    result = sandbox.exec(["python3", "-c", code])
    return result.stdout

output = run_code("print('hello')")  # sandbox is auto-managed

Async

@roche_sandbox(image="python:3.12-slim")
async def run_code(code: str, sandbox) -> str:
    result = await sandbox.exec(["python3", "-c", code])
    return result.stdout

Agent Framework Integration

The decorator strips the sandbox parameter from the function signature, so agent frameworks (OpenAI, LangChain, CrewAI, etc.) only see user-facing parameters:

from agents import function_tool

@function_tool
@roche_sandbox(image="python:3.12-slim")
def run_code(code: str, sandbox) -> str:
    """Execute Python code in a sandbox."""
    return sandbox.exec(["python3", "-c", code]).stdout

Parameters

Parameter	Type	Default	Description
image	str	"python:3.12-slim"	Container image
provider	str	"docker"	Sandbox provider
network	bool	False	Enable network access
writable	bool	False	Enable writable filesystem
timeout_secs	int	300	Sandbox timeout
memory	str | None	None	Memory limit (e.g. "512m")
cpus	float | None	None	CPU limit
sandbox_param	str	"sandbox"	Name of the injected parameter

Agent Framework Examples

See examples/python/ for integration examples with:

• OpenAI Agents SDK — @function_tool integration
• LangChain / LangGraph — custom BaseTool + stateful retry workflow
• CrewAI — @tool decorator + multi-agent crew
• Anthropic API — tool_use + multi-turn agentic loop
• AutoGen — custom CodeExecutor + group chat
• Camel-AI — BaseToolkit + role-playing session

All examples run without API keys (simulated mode) and optionally switch to real LLM calls.
