Sandboxed rollouts you call like typed Python (import as `agentix`)

Agentix

Sandboxed rollouts you call like typed Python.

Turn agents, tools, and scorers into Python callables. Package their dependencies into runtime images. Call them from evaluators, trainers, and orchestration code without writing a new runner for every pairing.

The 10-Second Model

Agentix has two primitives:

• Remote calls: client.remote(fn, *args, **kwargs) runs a Python callable inside a sandbox worker. The callable is serialized with stdlib pickle, Python's native callable reference mechanism.
• Bundles: agentix build [path] packages a Python project and its declared dependencies into a deploy-ready runtime image.

from agentix import RuntimeClient
from app import run

async with RuntimeClient(sandbox.runtime_url) as client:
    result = await client.remote(run, input="hello")

The unit of composition is not a bespoke benchmark runner or agent adapter. It is a Python callable.

Why Agentix Exists

Agent experiments sprawl quickly. One agent needs a CLI wrapper. Another needs a Python harness. A benchmark needs repo setup, grading scripts, and logs. A training loop needs the same pieces batched across many sandboxes.

Agentix collapses that matrix into one execution contract: if Python can serialize the callable and the sandbox has its dependencies, the host can call it.

You have	You expose	You call
Claude Code, Codex, Aider, OpenHands, or an internal agent	async def run(...) -> RunResult	await client.remote(run, ...)
Shell, files, repo setup, or local tools	async def run(command: str) -> BashResult	await client.remote(bash_run, ...)
SWE-bench, MLE-Bench, or an internal evaluator	async def score(...) -> Score	await client.remote(score, ...)
Streaming or interactive workflows	async def stream(...) -> AsyncIterator[Event]	async for event in client.remote(stream, ...)

What Ships

• Typed remote calls across the host-to-sandbox boundary.
• Unary, streaming, and bidirectional call shapes inferred from callable signatures.
• One runtime worker process today behind an internal worker backend boundary, so future pools or per-call isolation can stay API-compatible.
• Bundle builds from normal Python projects and pyproject.toml dependencies.
• Optional Nix system dependencies when a project includes default.nix.
• Deployment backend plugins through the agentix.deployment entry point group.

Quickstart

Install the host framework and a deployment backend:

pip install agentixx agentix-deployment-docker

Create a remote callable:

# src/hello_agentix/__init__.py
async def run(input: str) -> str:
    return f"sandbox saw: {input}"

Build a bundle:

agentix build ./hello-agentix -o hello-agentix:0.1.0

Deploy it and call the callable:

import asyncio

from agentix import RuntimeClient
from agentix.deployment.base import SandboxConfig, session
from agentix.deployment.docker import DockerDeployment
from hello_agentix import run


async def main() -> None:
    deployment = DockerDeployment()
    config = SandboxConfig(image="hello-agentix:0.1.0")

    async with session(deployment, config) as sandbox:
        async with RuntimeClient(sandbox.runtime_url) as client:
            print(await client.remote(run, input="hello"))


asyncio.run(main())

Architecture

Host process
  RuntimeClient.remote(fn, ...)
    serializes callable with pickle
    detects unary / stream / bidi
    encodes args and kwargs
        |
        v
Sandbox
  agentix-server
        |
        v
  worker subprocess
    unpickles callable
    validates args
    calls fn(*args, **kwargs)

Remote calls use Socket.IO events for unary, streaming, and bidirectional shapes. HTTP is kept only for /health. Errors stay in-band.
