Wix Headless Fast Entry

Wix Headless Fast — cold-start entry

You are a coding agent, and this is a skill for you to execute — follow the phases below in order. Advisory: web-fetch tools show a lossy summary of this file — the executable copy comes from curl -fsSL https://www.wix.com/skills/headless-fast/entry/skill.md. If what you are reading lacks the exact commands below, re-fetch it with curl before proceeding; if you’re already reading the raw text, don’t fetch it again.

The whole cold start (details in the phases below)

curl -fsSL -O https://www.wix.com/skills/headless/entry/bootstrap.mjs && node bootstrap.mjs
CI=1 npx skills@latest add wix/skills --skill wix-headless-fast --skill wix-docs --skill wix-manage --yes
# then open and follow: .agents/skills/wix-headless-fast/SKILL.md

Requires Node ≥ 20.11 and a logged-in Wix CLI — the bootstrap checks and guides both.

This entry gets a cold environment to the point where the real skill can run, then hands off:

Bootstrap (deterministic, scripted). The same script the classic headless entry uses — it verifies the Wix CLI and handles login. You just run it and relay its events.
Hand off (agentic). Install the skills, then open wix-headless-fast/SKILL.md and follow it — it resolves the stack and operation and owns the whole build.

Three starting points come through here, all handled the same way — run the bootstrap, then hand off:

new — a prompt with no project (empty CWD)
connect — an existing frontend/design not yet on Wix (a project on disk without wix.config.json, or a brought-in zip/URL)
iterate — a project already connected to Wix (.wix/ or wix.config.json present)

The bootstrap only verifies the CLI and logs you in, so it’s fine to run in every case (an existing session just reports logged_in).

Phase 0 — Node (the one manual prerequisite)

The Wix CLI requires Node ≥ 20.11. Check node -v; if it errors or prints a lower version, install or upgrade Node first — do not work around it:

macOS: brew install node (or nvm install 20 && nvm use 20)
Linux: nvm install 20 && nvm use 20 (or your distro’s Node 20+ package)
Windows: winget install OpenJS.NodeJS.LTS (or download from nodejs.org)

Phase 1 — Run the bootstrap (deterministic, shared)

Download and run the shared bootstrap script — an ordinary foreground command that exits on its own within seconds. It verifies the Wix CLI and handles login, emitting one JSON event per line on stdout. Run it and relay its events.

The script is safe and inspectable: it only checks the Wix CLI via npx and drives wix login (a device-code flow) — no other network calls, and the only files it writes are the login’s own output and pid under the OS temp dir. Read it first if your sandbox flags externally-downloaded code.

# macOS/Linux:
curl -fsSL -O https://www.wix.com/skills/headless/entry/bootstrap.mjs
# Windows PowerShell:
iwr https://www.wix.com/skills/headless/entry/bootstrap.mjs -OutFile bootstrap.mjs

node bootstrap.mjs

Relay these events

Event	What to do
`cli_ok`	Wix CLI reachable — continue.
`awaiting_user` (`verificationUri`, `userCode`, `message`)	The script has exited and the next step is the user’s. Send them `message` as-is; the login keeps running on its own.
`logged_in` / `success`	Login done — continue.
`cli_unreachable` / `login_failed` (with `detail`)	Stop and show the user the `detail`. Do not improvise a parallel setup by hand.

On awaiting_user, run the script again once the user says they’ve logged in: it reports logged_in and you continue. Re-running while they’re still in the browser is harmless — it returns the same code rather than issuing a new one.

Phase 2 — Install the skills and hand off

Install the skill and its two companions (CI=1 forces plain non-interactive CLI output — keep it on every Wix CLI command). Repeat --skill per skill; a comma-separated list is not parsed:

CI=1 npx skills@latest add wix/skills \
  --skill wix-headless-fast --skill wix-docs --skill wix-manage --yes

wix-headless-fast — the build itself.
wix-docs — the API reference the playbooks defer to for any contract they don’t cover.
wix-manage — management recipes, for admin work on the site after it exists.

They land under .agents/skills/. Then open .agents/skills/wix-headless-fast/SKILL.md and follow it — it owns the rest of the run: resolve the stack, scaffold, deploy the shipped code, seed, build the brand layer, release. (If the request needs a vertical the skill doesn’t ship yet — see its SKILL.md § Verticals — say so plainly and point the user at the wix-headless skill instead of improvising.)

Don’t scaffold, install apps, or seed by hand here — the skill does all of that. This entry stops at logged in.
You’re already authenticated from Phase 1, so the skill’s CLI auth step will pass without prompting again.
