Ship runtime usage guide for code execution sandboxes. Covers Python execution via IPython kernel with persistent variables, Shell command execution, filesystem operations with security constraints, and common development workflows. Use this when working inside a Ship container to understand available tools, pre-installed libraries, path security rules, and best practices for file I/O, data processing, and project scaffolding.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Ship Runtime: Python & Shell Sandbox Ship is a containerized execution environment providing three core capabilities: **Python** (via IPython kernel), **Shell**, and **Filesystem** operations. All operations are confined to the `/workspace` directory. ## Container Base Image - **Base**: `python:3.13-slim-bookworm` (Debian Bookworm minimal) - **Runtime user**: `shipyard` (uid 1000, passwordless sudo) - **Workspace**: `/workspace` (mounted as shared Cargo Volume) ## Architecture ``` ┌────────────────────────────────────┐ │ Ship Container │ │ │ │ ┌──────────┐ ┌───────────────┐ │ │ │ IPython │ │ Shell/Bash │ │ │ │ Kernel │ │ Executor │ │ │ └─────┬─────┘ └──────┬───────┘ │ │ └───────┬────────┘ │ │ ┌──────┴──────┐ │ │ │ Filesystem │ │ │ │ /workspace │ │ │ └─────────────┘ │ └────────────────────────────────────┘ ``` ## Capability 1: Python Execution Python code runs inside an **IPython kernel**. Variables, imports, and state persist across calls within the same sandbox session. ### Key Behaviors …

How to install
mdr add astrbotdevs/shipyard-neo/python-sandbox@sha256:a8bf0aaf191ab7c4The line at the top of this page pins the label git:20260330.f776cf8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
