--- name: atlas description: Provision and drive Atlas machines — cloud VMs attached to an Atlas workspace, with public URLs for anything you serve. Use whenever the user asks you to build, run, test, host, or ship anything: offload the work to a machine and drive it end to end with the `atlas` CLI (machine create/exec/put/get/ports/rm), then hand back a live URL. Also provides ping_user, the required way to ask the user a question: it pages them and blocks for their reply instead of stalling in chat. Covers install, login, the offload loop, ports and public URLs, workspace paths, specialists and sources, exit codes, the ping log, cost, and cleanup. --- # atlas Remote dev VMs you drive on the user's behalf, each one attached to an Atlas workspace. A machine is your default place to build and run things — off the user's laptop, with a public URL at the end instead of "it works locally". Backed by `@atlaslabsnpm/cli` (binary: `atlas`). Machines run on Modal. **This file is the spec.** Every command, flag, path rule and exit code below is read off the CLI source. If something is not here, do not assume it exists — run `atlas` with no arguments to print the built-in help rather than guessing a flag. --- ## MUST — offload to a machine When this skill is active: - **Run build / install / dev-server / test work on an Atlas machine, not the user's laptop.** Don't ask "should I use a VM?" — create one and use it. - **Drive it end to end** — create → push files → install/build/run → hand back a live URL — without stopping after each step to ask permission to continue. - **Deliver a public URL**, never "it's running on port 3000 locally." - **Stop the machine when the work is done.** A running machine bills. - **Never stall in the chat waiting on the user.** If you need them, use `ping_user` (below) and keep working on everything that does not depend on the answer. - **Use the CLI, not `curl`.** `atlas` reads the saved token itself, so the command shape stays constant and the user approves `atlas` once instead of approving a fresh hand-rolled HTTP line every time. --- ## Install ```bash npm install -g @atlaslabsnpm/cli # requires Node.js 20+ ``` No npm, or a locked-down box: ```bash curl -fsSL https://www.atlaslabs.id/install.sh | sh ``` Installs one self-contained file to `/usr/local/bin` when writable, else `~/.local/bin`. Never needs `sudo`; verifies a SHA-256 checksum before anything lands on PATH. Single file, no installer at all: ```bash curl -fsSL https://www.atlaslabs.id/download/atlas.cjs -o atlas.cjs node atlas.cjs whoami ``` `atlas.cjs` is a valid entrypoint name — the CLI only auto-runs when invoked as `cli.ts`, `cli.js`, `atlas.cjs`, `atlas.js`, or `atlas`. --- ## Authenticate ```bash atlas login # device flow, opens a browser for approval atlas whoami # → email (name) atlas logout # revokes server-side, then deletes the local token ``` `login` posts to `/api/v1/auth/device/code`, prints a **user code** and a verification URL, opens the browser, then polls `/api/v1/auth/device/token` at the server-supplied interval until the user approves or the code expires. **Never ask the user to paste a token into the chat**, and never print one. If the browser does not open, the CLI prints `Open this URL manually: …` — relay that line rather than re-running `login`. ### Where state lives | | Path | |---|---| | Config dir (Windows) | `%APPDATA%\atlas` | | Config dir (else) | `$XDG_CONFIG_HOME/atlas`, else `~/.config/atlas` | | Token (macOS) | Keychain, service `id.atlaslabs.cli`, account = your username | | Token (fallback) | `/token`, mode `0600` | | Settings | `/config.json` — `{ baseUrl?, currentGroup? }` | | Install id | `/installation` — a continuity hint only, carries no authority | `ATLAS_BASE_URL` overrides the server; `baseUrl` in `config.json` also does. Default is `https://www.atlaslabs.id` — always the **`www`** host. The apex redirects, and a redirect hop drops the `Authorization` header, so an apex call lands unauthenticated. If `whoami` shows an identity you did not expect, check `ATLAS_BASE_URL` and `config.json` before doing anything else. --- ## Groups and workspaces Every machine, specialist and source lives in a **workspace**. Which workspace is resolved, in order: 1. `group:` in `atlas.yaml` in the current directory 2. `currentGroup` in `config.json` 3. otherwise, your **personal** workspace ```bash atlas group list # `*` marks the current group atlas group create "Acme Team" # creates and switches to it atlas group use acme-team # switch ``` A `group` value that names no group you belong to is a hard failure, not a silent fall back to personal. ### Invite a human ```bash atlas invite ben@example.com --role builder --machine my-app atlas member invite ben@example.com builder # older positional form, still works ``` Roles: `owner` | `builder` | `operator` | `viewer`. Default `operator`. `--machine ` names the machine they are being brought in for, so the invite email arrives with the machine id in it. A flag whose value is missing or is itself another flag is an **error**, not a default — `--machine --role owner` will not invite someone to a machine called `--role`. The command prints the accept URL. If email delivery failed it says so and the link is the fallback — hand the link over rather than re-inviting. **The invitee must open that link before anything else works.** Accepting is what creates their membership; until then `atlas group use ` reports `Unknown group ""`, because groups are listed through memberships. The link is bound to the invited address and expires in 7 days, so it has to be opened by whoever that email belongs to — forwarding it does not transfer it. Spaces can also be shared from the web UI at `/app/spaces`, which invites into the group that owns the space. --- ## The offload loop **1. Create a machine.** The slug is required and is a DNS label — lowercase letters, numbers and dashes, 1–63 chars. ```bash atlas machine create my-app # → Created my-app (running) # atlas://workspace/my-app atlas machine create my-app --template ``` Creating a slug that already exists is a **409, not a second machine**. That is deliberate: re-running create is safe and never double-bills. **2. Push files.** Write locally, then upload. ```bash atlas put my-app ./server.js server.js # → /workspace/server.js atlas put my-app ./index.html public/index.html ``` **3. Start long-running work in the background** so `exec` returns instead of hanging: ```bash atlas exec my-app -- 'cd /workspace && (nohup node server.js >/tmp/dev.log 2>&1 &)' ``` **4. Poll until it is up:** ```bash atlas exec my-app -- 'curl -s -o /dev/null -w %{http_code} localhost:3000' # not 200 yet? read the log: atlas exec my-app -- 'tail -50 /tmp/dev.log' ``` **5. Hand back the public URL:** ```bash atlas ports my-app ``` **6. Stop it when done:** ```bash atlas machine rm my-app ``` --- ## What the machine actually is Verified on the live image — do not guess beyond this: | | | |---|---| | OS | Debian 12 (bookworm), x86_64, on gVisor | | User | **root** | | Workdir | `/workspace` | | Preinstalled | node v22, npm, pnpm, python3 3.13 + pip, git, curl, gcc, make | | Exposed ports | **3000 and 8000**, each with a public HTTPS tunnel URL | **Bind servers to `0.0.0.0`**, not `127.0.0.1`, or the tunnel cannot reach them. **Ports are fixed when the machine is created.** 3000 and 8000 are the only ones routable from outside; a server on 5173 is unreachable. Configure the tool to use 3000 (`vite --port 3000`, `next dev -p 3000`) rather than trying to expose another port. Anything else you need — a database, a language runtime — install it in the machine (`apt-get install -y …`, `pip install`, `npm i -g`). You are root. --- ## `exec` — running commands ```bash atlas exec -- atlas exec # `--` optional when nothing looks like a flag ``` - Everything after the **first `--`** is the remote command, verbatim, including anything that looks like a flag. Without `--`, the whole tail is the command. - Arguments are joined with spaces and run **through a shell**, so `&&`, pipes, redirects and subshells work. Quote accordingly. - stdout goes to stdout, stderr to stderr. - **`exec` mirrors the remote exit code.** `atlas exec app -- npm test` fails your script when the tests fail. Rely on that rather than grepping stdout. - `exec` is request/response, not a stream: a command that never returns will hold the call open. Background anything long (`nohup … &`) and poll. --- ## `put` / `get` — file transfer ```bash atlas put atlas get [localPath|-] ``` Remote paths are **workspace-relative** (the workdir is `/workspace`): | You write | Result | |---|---| | `server.js` | `/workspace/server.js` | | `public/index.html` | `/workspace/public/index.html` | | `/workspace/server.js` | accepted; the prefix is stripped | | `/etc/hosts` | **refused with an error** | Other absolute paths are refused rather than silently rewritten — turning `/etc/hosts` into a workspace-relative write is the kind of guess that quietly puts a file somewhere the user did not ask for. `get` with no local path, or `-`, writes the bytes to **stdout** — pipe it. --- ## HARD RULE — ask with `ping_user`, never in the chat When this skill is active and you need something from the user, you **must** reach them with `ping_user`. Stopping to ask in the chat is not the fallback; it is the thing this replaces. ```bash atlas ping_user my-app "Postgres or SQLite for the todo store?" --timeout 300 ``` It **blocks until they answer** and prints **only their reply on stdout**, so capture it and keep going: ```bash DB=$(atlas ping_user my-app "Postgres or SQLite for the todo store?") echo "using $DB" ``` Everything else — the question, the reply link, delivery status — goes to stderr, so `$(...)` gets a clean answer and nothing else. ### Flags | Flag | Effect | |---|---| | `--timeout ` | How long to wait. Default **300**. Must be a positive number. | | `--context
