CreateOS Integrations

Claude Code, Codex, Pi, OpenCode & DeepSeek Harness plugins for disposable sandbox compute.

Run code off your machine in disposable CreateOS Sandboxes — from Claude Code, Codex, Pi, OpenCode, or DeepSeek Harness.

Why

Heavy builds, flaky test suites, and untrusted code don't belong on your laptop. claude-code-plugin gives Claude a skill + slash commands that offload them to throwaway CreateOS Sandboxes — created and running your first command in roughly 200 ms, self-destructing when done — so your machine stays free, your deps stay isolated, and untrusted code never touches local state.

🧨 Disposable — one-shot offload stages a dir, runs, pulls artifacts, then auto-destroys. Box-side changes never touch local unless you ask.
⚡ Fast — ~200 ms from create to first command; parallel fanout across N boxes for matrix builds and split test suites.
🔒 Isolated — untrusted code runs in a disposable Sandbox, not your shell. Egress can be locked to an exact allowlist.
🔁 Live loops — a reusable per-repo box with file sync, port tunnels, and public HTTPS expose for real dev sessions.
💤 Cheap to keep — pause snapshots a warm box (deps and all) at zero compute cost; resume brings it back in a handful of seconds.

Quick start

Claude Code:

# 1. Add the marketplace + install the plugin
/plugin marketplace add NodeOps-app/createos-claude-plugins
/plugin install @createos/claude-code@createos

# 2. Offload a heavy test run to a throwaway box (auto-destroys)
/createos-sandbox:offload . "npm ci && npm test"

Pi:

# 1. Install the extension from this repository
pi install git:github.com/NodeOps-app/createos-claude-plugins

# 2. Start Pi locally with CreateOS sandbox tools available
pi

# Optional: create a sandbox and route Pi's built-in tools into it
pi --inside-createos-sandbox

# Optional: copy this project to /root/workspace before sandbox-mode Pi starts
pi --inside-createos-sandbox --createos-sync-once

# Optional: continuously sync this project and /root/workspace in sandbox mode
pi --inside-createos-sandbox --createos-watch

Codex:

# 1. Add the marketplace
codex plugin marketplace add NodeOps-app/createos-claude-plugins

# 2. Install the plugin
codex plugin add @createos/codex@createos

# 3. Launch codex — the skill teaches createos CLI usage
codex

OpenCode:

# 1. Install the plugin
opencode plugin @createos/opencode --global

# 2. Launch opencode — sandbox tools are available automatically
opencode

DeepSeek Harness:

# 1. Install the bundle from this monorepo checkout
dsh plugin --profile web add /path/to/createos-claude-plugins/packages/dsh-createos

# 2. Configure CreateOS sandbox credentials
export CREATEOS_SANDBOX_API_KEY='...'
export CREATEOS_SANDBOX_SHAPE='s-2vcpu-2gb'

# 3. Start DSH Web from the workspace path the remote tools should use
dsh web

The Claude Code, Codex, Pi, and OpenCode integrations use the createos CLI, which auto-installs on first use. Sign in once with createos login (browser OAuth, run it in your own terminal) or export CREATEOS_API_KEY=<key>; check with cos auth. The DeepSeek Harness integration uses @nodeops-createos/sandbox and CREATEOS_SANDBOX_* environment variables. Prefer a local checkout? See Install.

Packages

Package	What it does
claude-code-plugin	Hooks-based Claude Code plugin — offload, parallel fanout, scratch shell, reusable box with sync, port tunnel, public HTTPS expose, private-network clusters, BYO-S3 disk mounts, WireGuard VPN, and snapshot/fork — all driving the authed `createos` CLI.
pi-extension	Pi coding agent extension with all 33 `sandbox_*` tools for lifecycle, configuration, port tunnels, file sync, private networks, persistent disks, and device VPN. Built-in tools route remotely only with `--inside-createos-sandbox`.
@createos/codex	Codex plugin — skill that teaches the `createos` CLI for sandbox lifecycle, networking, disks, and VPN.
@createos/opencode	OpenCode plugin with 33 sandbox tools (`sandbox_exec`, `sandbox_push`, `sandbox_pull`, networks, disks, VPN, sync) and system prompt injection for sandbox-first workflows.
@nodeops-createos/dsh-createos	DeepSeek Harness bundle that replaces `ctx.fs` and `ctx.subprocess` together, so Bash, file, LSP, and PTY consumers operate inside one CreateOS sandbox without provider-specific tool forks.

Claude Code — commands at a glance

Command	What
`/createos-sandbox:offload <dir> <cmd>`	one-shot: stage → run → pull artifacts → destroy
`/createos-sandbox:fanout <dir> <cmd1> [cmd2 …]`	run each command in its own throwaway box, in parallel
`/createos-sandbox:shell`	instant throwaway interactive Linux (destroyed on exit)
`/createos-sandbox:up` · `run` · `sync` · `down`	reusable per-repo box + file sync for live dev loops
`/createos-sandbox:tunnel <port>`	forward a box port to `127.0.0.1` (private)
`/createos-sandbox:expose <port>`	public HTTPS URL for a box port
`/createos-sandbox:cluster …`	N boxes on one private network, name-addressable
`/createos-sandbox:disk …`	mount your own S3 bucket into the project box
`/createos-sandbox:vpn …`	WireGuard L3 into your private networks
`/createos-sandbox:fork`	snapshot the project box → independent clone
`/createos-sandbox:pause` · `resume`	park the warm box at zero compute cost, then restore it exactly
`/createos-sandbox:template …`	build a custom image so boxes boot with the toolchain already installed
`/createos-sandbox:status`	show active box + sync + tunnels + cluster

Full flags, networking guide, and heavy-build tips live in the Claude Code Plugin README.

Pi — commands at a glance

Pi and built-in tools run locally by default. --inside-createos-sandbox routes built-ins (bash, read, write, edit, ls, find, grep) to a sandbox; all 33 sandbox lifecycle, networking, disk, and device-VPN tools remain available in either mode.

Command	What
`/sandbox`	Show sandbox status
`/network create <name>`	Create a private network
`/network ls`	List your networks
`/network show <name>`	Show network members + IPs
`/network attach <name>`	Join this sandbox to a network
`/network detach <name>`	Leave a network
`/network rm <name>`	Delete a network
`/device status`	Show registered devices
`/device attach <network>`	Give your machine access to a network
`/device detach <network>`	Remove access

Flags

Flag	Purpose
`--inside-createos-sandbox`	Run Pi inside a sandbox
`--createos-shape <shape>`	Sandbox shape (default: `s-2vcpu-2gb`)
`--createos-rootfs <name>`	Base image or template
`--createos-network <name>`	Network(s) to join at creation
`--createos-sync-once`	Copy project to `/root/workspace` once
`--createos-avoid-git-ignore`	Include Git-ignored files in that copy
`--createos-watch`	Two-way project sync for this session

Use --createos-sync-once, --createos-watch, and other --createos-* flags with --inside-createos-sandbox. The sync flags are mutually exclusive. The first preserves sandbox-only files and excludes VCS metadata plus Git-ignored files by default; --createos-avoid-git-ignore includes ignored files. The latter starts the existing two-way sync. In sandbox mode, loaded Pi skill directories are mirrored before the first agent turn; Pi credentials, settings, and sessions stay local.

Full tool inventory lives in the Pi Extension README.

DeepSeek Harness — execution world

The DSH bundle replaces the local filesystem and subprocess providers with CreateOS-backed providers over one shared sandbox. It uses the CreateOS SDK and managed-process API rather than the createos CLI.

Surface	What runs remotely
`ctx.fs`	read, write, edit, glob, search, and atomic writes
`ctx.subprocess`	one-shot Bash commands and managed process waits
PTY terminals	persistent terminal sessions via managed PTYs

Full reference in dsh-createos/README.md.

Install

From GitHub (recommended):

/plugin marketplace add NodeOps-app/createos-claude-plugins
/plugin install @createos/claude-code@createos

From a local checkout:

git clone https://github.com/NodeOps-app/createos-claude-plugins
/plugin marketplace add /path/to/createos-claude-plugins
/plugin install @createos/claude-code@createos

DeepSeek Harness from a local checkout:

dsh plugin --profile web add /path/to/createos-claude-plugins/packages/dsh-createos

Dev (instant, no install):

claude --plugin-dir /path/to/createos-claude-plugins/packages/claude-code-plugin
/reload-plugins      # after editing plugin files

Requirements

CreateOS account — the createos CLI auto-installs on first use. Opt out with COS_NO_AUTOINSTALL=1.
Sign-in — createos login in your own terminal (interactive browser OAuth; Claude can't drive a TTY prompt), or export CREATEOS_API_KEY=<key> to skip the browser entirely. cos auth reports which is active.
DeepSeek Harness env: CREATEOS_SANDBOX_API_KEY and CREATEOS_SANDBOX_SHAPE; optional CREATEOS_SANDBOX_BASE_URL and CREATEOS_SANDBOX_ROOTFS.
Host tools: jq, tar, bash, base64; perl for ANSI/path handling; curl for the one-time CLI install.

Safety

One-way by default — offload uploads and sync are laptop → box; box-side writes never flow back unless you opt in (-2).
Excludes — .git, node_modules, target, .venv, and other regenerable dirs are stripped from uploads by default.
Scoped — cos only ever touches boxes it created (cos-*) or the project box in its statefile. Your other sandboxes are never touched.
Quota — external keys have been observed to allow 2 boxes running at once, with a daily creation cap. This is observed behaviour, not published policy — budget cluster and fanout against it and expect excess jobs to queue rather than fail.

Contributing

Issues and PRs welcome. The Claude Code, Codex, Pi, and OpenCode plugins are thin surfaces over the createos CLI; keep those command surfaces aligned. The DeepSeek Harness bundle uses the CreateOS SDK and managed-process API, so keep it aligned with the SDK and control-plane API.
