# SWE-ReX — Agent Guide

name: swe-rex ｜ version_range: 1.4.0~1.4.0 ｜ generated: 2026-08-28

title_en: SWE-Rex - Sandboxed Agent Code Execution ｜ desc_en: Local/cloud sandboxed code execution with parallelism (by SWE-agent).

Preflight

note: Requires Python >= 3.10; sandbox execution requires Docker.

python3 --version && docker --version 2>/dev/null || echo docker-missing

预期输出: see command output

Install

note: Tsinghua mirror recommended in mainland China.

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple swe-rex==1.4.0
swerex-remote --help

预期输出: usage: swerex-remote [-h] [--host HOST] [--port PORT] --auth-token AUTH_TOKEN

Operations

Inspect CLI surface

note: Verified in this environment.

swerex-remote --help

预期输出: server parameter surface (--host/--port/--auth-token)

Verify library imports

note: Verified in this environment.

python3 -c "import swerex; print('swerex OK')"

预期输出: swerex OK

Start sandbox execution server

note: Requires Docker + auth token; sandbox run not tested in this environment.

swerex-remote --host 127.0.0.1 --port 8000 --auth-token <token>

预期输出: server listening (for agent clients to connect and execute code)

Python API integration

note: Official form; requires server started first; not tested in this environment (no Docker).

python3 - <<'PY'
import asyncio
from swerex import RemoteSandbox
async def main:
    sandbox = RemoteSandbox(host="127.0.0.1", port=8000, auth_token="<token>")
    print(await sandbox.run("echo hi"))
asyncio.run(main)
PY

预期输出: hi (requires server started first; not tested in this environment — no Docker)

Uninstall

note: Idempotent pip uninstall; sandbox containers cleaned up as needed.

pip uninstall -y swe-rex 2>/dev/null || true
command -v swerex-remote >/dev/null 2>&1 && echo '残留: swerex-remote 仍存在' || echo 'swe-rex removed: OK'

预期输出: see command output

Facts

writes: none (CLI/library) ｜ runtime: Python >= 3.10, Docker for sandbox ｜ notes: sandbox execution not tested in this environment (no Docker); no background process
