What it does

Vm Provisioning is an agent skill from TwiTech-LAB/devchain. Prepare a DevChain remote VM for development of a project. Find the tools the project needs from its CI, version files, manifests and docs, install the missing ones, and mark the project as provisioned on this VM. Runs only on a claimed DevChain VM. Use at agent start when devchain status prints remote VM, when a command on the VM fails because a tool is missing, or when the user asks to provision or prepare the VM. Triggers: provision the VM, prepare the VM, install the dev stack, VM is missing tools, remote VM…

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `provision.sh`). Compatibility notes: DevChain remote VMs (Ubuntu or Debian) claimed by a home DevChain

It sits in DevOps & Cloud. It works with PHP. The repository describes itself as: Run a team of AI coding agents. On your machine. Local-first orchestration for Claude Code, Codex, OpenCode, Antigravity, and Copilot. The licence is MIT.

When your agent uses it

  • Asks to provision

Example prompts

  • “/vm-provisioning”

Requirements

  • Python 3
  • Node.js
  • A Bash shell
  • Docker
  • Compatibility (from SKILL.md): DevChain remote VMs (Ubuntu or Debian) claimed by a home DevChain

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Find the script
  2. Check
  3. Find the requirements
  4. Install what is missing
  5. Mark
  6. Report
  7. Install Docker (only when it is missing)

What it can do on your machine

Read from SKILL.md and the folder at commit 172b47c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • nvm
    • docker
    • curl
    • apt-get
    • npm
    • apt
    • bash
    • php
    • pnpm
    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use docker, curl, npm, pnpm and pip, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    DevChain remote VMs (Ubuntu or Debian) claimed by a home DevChain

    From compatibility in the SKILL.md frontmatter.

Context cost

Vm Provisioning loads about 1.8k tokens when it runs. Until then it costs about 136 tokens; SKILL.md has 944 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~136
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

VM Provisioning

A DevChain remote VM starts as a generic machine. Only the project folder comes from home. This skill installs the development stack that the project needs on the VM. Then it marks the project as provisioned on this VM.

Step 0 — Find the script

  1. Call devchain_get_skill with slug vm-provisioning. Note the returned contentPath.
  2. The script is <contentPath>/provision.sh. Run it with bash.

Below, $P means bash <contentPath>/provision.sh.

Step 1 — Check

Run $P check.

OutputAction
homeStop. Home needs no provisioning.
provisionedStop. Continue your task.
not provisionedGo to Step 2.

If a command later fails because a tool is missing, do Steps 2 to 6 for that tool, even when the check prints provisioned.

Step 2 — Find the requirements

Read these sources in this order. When two sources conflict, the earlier source wins.

  1. CI workflows (.github/workflows/*.yml, .gitlab-ci.yml). They show the exact tools and versions that build the project.
  2. Version files: .nvmrc, .node-version, .tool-versions, .python-version, .ruby-version.
  3. Manifests: package.json (engines, packageManager), composer.json (require.php, ext-*), pyproject.toml, requirements*.txt, go.mod, Gemfile, Cargo.toml, pom.xml, build.gradle.
  4. Dockerfile and Compose files. Base images show the runtimes. Services show the databases, caches and queues.
  5. Setup docs: README, CONTRIBUTING, docs/AGENTS.md, and the setup or development pages in docs/.

Write a list. For each tool, give the tool, the required version and the source (file:line).

Step 3 — Install what is missing

Check each tool first (for example php -v). Install only the tools that are missing or have the wrong version.

Run devchain status once. Its second line says whether sudo works without a password. If the line does not start with sudo: yes, ask the user before you run any sudo command.

NeedMethod
OS packages (PHP, web server, build tools, database clients)Run sudo apt-get update once. Then run sudo apt-get install -y <packages>.
A version that the distribution does not haveAsk the user before you add a third-party package repository (for example the ondrej/php PPA).
Node.jsUse DevChain's Node (/usr/local/bin/node) when it meets the requirement. If not, install nvm in the user's home, run nvm install <version>, then run nvm alias default system. Run project commands with nvm exec <version> <command>.
pnpm or YarnUse corepack with the version in packageManager, or npm install -g <tool>@<version>.
PythonUse the system python3 and a project .venv. For another version, use uv or pyenv in the user's home.
Databases, caches, queuesIf the project has a Compose file, use it (docker compose up -d <service>). If not, install the OS package and bind the service to 127.0.0.1.
DockerDevChain installs Docker when it sets up the VM. If docker version or docker compose version fails without sudo, install Docker as Step 6. Never install it with apt or a script.

Do not install project dependencies (npm ci, pnpm install, pip install) as part of provisioning. File sync does not copy node_modules, .venv, dist, build or target between home and the VM. The agent whose task needs them installs them. vendor/ (Composer) syncs with home, so home's copy arrives on the VM.

Never do these

DevChain runs on this VM. Each action below can break DevChain, its agents or the file sync.

  • Do not replace, upgrade or remove /usr/local/bin/node, npm, or anything under /opt/devchain-host. DevChain and the Codex and Copilot CLIs run on this Node.
  • Do not set a global default Node (for example nvm alias default 18). New agent shells then start the provider CLIs on the wrong Node.
  • Do not install, upgrade or remove the provider CLIs: claude, codex, copilot, opencode, agy. DevChain pins their versions.
  • Do not install Docker yourself. Do not change users or groups (usermod, groupadd). Use Step 6: DevChain installs Docker, adds the user to the docker group and restarts itself safely.
  • Do not stop, restart or change devchain-host, devchain-bootstrap or Syncthing. Do not use port 3000 or 22000. Run ss -ltn before you pick a port for a service.
  • Do not turn on or change a firewall (ufw, iptables). Do not change the SSH settings.
  • Do not run apt upgrade, apt full-upgrade or do-release-upgrade. Do not reboot.
  • Do not replace /usr/bin/python3. The OS tools use it.
  • Do not change project files for provisioning. The project folder syncs with home.
  • Do not create, copy or print secrets. If the project needs credentials, tell the user.

Step 4 — Mark

Run $P set.

The marker is the file ~/.devchain/provisioning/<DEVCHAIN_PROJECT_ID> on the VM. It is outside the project folder, because the project folder syncs with home. It holds the claimedAt value of /etc/devchain-host/claim.json. A reset or a reinstall claims the VM again and writes a new value, so $P check then prints not provisioned. An update keeps the value.

Step 5 — Report

Tell the user in short lines:

  • what you installed, with versions;
  • what was already present;
  • what the user must do (for example a third-party repository or credentials).

If Docker is missing, also tell the user: "DevChain now installs Docker and restarts. All agent sessions on this VM stop. Start them again when the install is done."

Step 6 — Install Docker (only when it is missing)

Warning: DevChain restarts at the end of the install. Your session and every other agent session on this VM stop. Do this step last.

  1. Complete Steps 4 and 5 first.

  2. Start the install:

    bash
    curl -sS -X POST "$DEVCHAIN_API_URL/api/host/docker" -H 'Content-Type: application/json' -d '{}'

  3. A 202 reply with "state":"pending" means that the install started. Do nothing more. DevChain restarts when the install is done.

  4. A 404 reply or the code HOST_HELPER_OUTDATED means that this VM runs an older DevChain. Tell the user to run Update VM in Cloud, then press Install Docker there.

To read the progress, run curl -sS "$DEVCHAIN_API_URL/api/host/docker".
