Runs a coding agent (Claude Code, OpenCode, Codex or any other) inside a persistent smolvm machine with the project mounted, so it can run with full permissions without touching the host. Use when someone wants to sandbox their coding agent, run it in skip-permissions or YOLO mode safely, or give it a disposable environment it can install anything into. Do not use it to run untrusted code with no network; use throwaway-machine for that.
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
# A coding agent in a machine Verified on **smolvm v1.27.4** on Linux x86_64, 2026-10-14, and on **v1.29.0** on macOS arm64, 2026-10-15. Done means the agent runs inside the machine from the project directory, its edits appear on the host, and git works on the mounted repo. ## Procedure **1. Copy the Smolfile into the project.** Edit the `npm install` line in `init` to the agents you use; any install command works. ```bash cp docs/coding-agent/assets/agent.smolfile ./Smolfile ``` **2. Create and start the machine.** Pass API keys as references so they are read from your host at launch, never written to the machine record: ```bash smolvm machine create --name agent -s Smolfile --secret-env ANTHROPIC_API_KEY=ANTHROPIC_API_KEY smolvm machine start --name agent # first start runs init: under a minute once the image is pulled ``` The Smolfile forwards your SSH agent, so `start` needs `SSH_AUTH_SOCK` set on the host: without it, it stops with `ssh-agent: SSH_AUTH_SOCK is not set`. Start one with `eval $(ssh-agent)`, or delete the `[auth]` block. **3. Run the agent.** ```bash smolvm machine exec --name agent -it -- claude --dangerously-skip-permissions …

How to install
mdr add smol-machines/smolvm/coding-agent@sha256:a2fe11bcbba3d250The line at the top of this page pins the label git:20261016.432b170, 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.
