What it does

Launch is an agent skill from popmechanic/VibesOS. Self-contained SaaS pipeline — invoke directly, do not decompose. Generates a Vibes app, adds auth + billing, and deploys live. Uses Agent Teams to parallelize for maximum speed. Use when the user wants to build and ship a complete SaaS product in one step, or says "launch", "ship it", "build and deploy".

Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `LAUNCH-REFERENCE.md` and `prompts/builder.md`). Compatibility notes: Requires Claude Code with Agent Teams support

It sits in Agent Workflows. The repository describes itself as: A GUI for Claude Code that makes it easy to vibe code simple, un-hackable apps. The licence is MIT.

When your agent uses it

  • The user wants to build and ship a complete SaaS product in one step
  • Build and deploy

Example prompts

  • “launch”
  • “ship it”
  • “build and deploy”
  • “/launch”

Requirements

  • A credential in OPENROUTER_API_KEY
  • Compatibility (from SKILL.md): Requires Claude Code with Agent Teams support
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Glob, Grep, AskUserQuestion, Task, Teammate, SendMessage, TaskCreate, TaskUpdate, TaskList, TaskGet

Workflow steps

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

  1. Collect Inputs
  2. Build
  3. Assembly & Deploy
  4. Verify & Cleanup

What it can do on your machine

Read from SKILL.md and the folder at commit 5baf8a2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash
    • Glob
    • Grep
    • AskUserQuestion
    • Task
    • Teammate
    • SendMessage

    …and 4 more on the same allowed-tools line.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • bun

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

  • Network

    No URLs in SKILL.md.

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • OPENROUTER_API_KEY

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

  • Compatibility

    Requires Claude Code with Agent Teams support

    From compatibility in the SKILL.md frontmatter.

Context cost

Launch loads about 3k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 1,211 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~3k

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.

  • NoteMentions a .env fileSKILL.md:39
    **DO NOT check .env, credentials, or project state before asking this question.**
  • NoteMentions a .env fileSKILL.md:146

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Write, Edit, Bash, Glob, Grep, AskUserQuestion, Task, Teammate, SendMessage, TaskCreate, TaskU

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.

Notation

Ask [Header]: "question" means call AskUserQuestion with that header and question. Options listed as bullets. User can always type custom via "Other".

For architecture context, see LAUNCH-REFERENCE.md in this directory.


FIRST: Terminal or Editor UI?

This is the very first question — ask before anything else. DO NOT check .env, credentials, or project state before asking this question. DO NOT invoke any other skill before asking this question. If Editor is chosen, skip ALL remaining steps — the editor handles everything.

Ask the user:

"How do you want to build? Editor (opens a browser UI with live preview, chat, and deploy button) or Terminal (I'll generate and deploy from here)?"

Present Editor as the first/recommended option.

  • If Editor: Start the editor server and END YOUR TURN. Do not ask any more questions. Do not continue to Phase 0 or any phase below. The editor UI handles the entire workflow — setup, generation, preview, deploy.

    Launch the editor server:

    bash
    VIBES_ROOT="${CLAUDE_PLUGIN_ROOT:-$(dirname "$(dirname "${CLAUDE_SKILL_DIR}")")}"
    bun "$VIBES_ROOT/scripts/server.ts" --mode=editor --prompt "USER_PROMPT_HERE"

    If no prompt was given, omit --prompt:

    bash
    VIBES_ROOT="${CLAUDE_PLUGIN_ROOT:-$(dirname "$(dirname "${CLAUDE_SKILL_DIR}")")}"
    bun "$VIBES_ROOT/scripts/server.ts" --mode=editor

    Tell the user: "Open http://localhost:3333 — the editor handles everything from here." Your job is done. Stop. Do not read further. Do not proceed to any phase below.

  • If Terminal: Continue with the workflow below.


⛔ EVERYTHING BELOW IS TERMINAL MODE ONLY

If the user chose Editor above, STOP. Do not read or execute anything below this line. The editor UI handles setup, generation, preview, and deployment.


Auth Check (Terminal mode only — silent unless needed)

Check for cached auth. Editor mode handles auth in the browser, so this only runs for Terminal:

bash
VIBES_ROOT="${CLAUDE_PLUGIN_ROOT:-$(dirname "$(dirname "${CLAUDE_SKILL_DIR}")")}"
bun --input-type=module -e "
import { readCachedTokens, isTokenExpired } from '$VIBES_ROOT/scripts/lib/cli-auth.js';
const tokens = readCachedTokens();
if (tokens && !isTokenExpired(tokens.expiresAt)) {
  console.log('AUTH_OK');
} else {
  console.log('AUTH_NEEDED');
}
"
  • If AUTH_OK → proceed silently (do not mention auth)
  • If AUTH_NEEDED → ask: "To deploy apps, you'll need a Vibes account. Sign in now? (A browser window will open for Pocket ID — takes about 10 seconds.)"
    • If yes:
      bash
      VIBES_ROOT="${CLAUDE_PLUGIN_ROOT:-$(dirname "$(dirname "${CLAUDE_SKILL_DIR}")")}"
      bun --input-type=module -e "
      import { getAccessToken } from '$VIBES_ROOT/scripts/lib/cli-auth.js';
      import { OIDC_AUTHORITY, OIDC_CLIENT_ID } from '$VIBES_ROOT/scripts/lib/auth-constants.js';
      const tokens = await getAccessToken({ authority: OIDC_AUTHORITY, clientId: OIDC_CLIENT_ID });
      if (tokens) console.log('Signed in successfully!');
      "
      Confirm success, then continue.
    • If no → proceed anyway (auth will be needed at deploy time)

Pre-Flight Check

Only one check before collecting input:

#CheckCommandIf True
1app.jsx existstest -f app.jsxAsk [Reuse]: "app.jsx exists. Reuse it or regenerate?" If reuse: skip T1.

Auth and deploy credentials are handled automatically — no user setup needed. On first deploy, a browser window opens for Pocket ID login. Tokens are cached at ~/.vibes/auth.json.

Phase 0: Collect Inputs

0.1 App Prompt

Ask [App prompt]: "What do you want to build? Describe the app you have in mind."

  • "Todo list" — A simple task manager with categories and due dates
  • "Photo gallery" — A shareable photo gallery with albums and captions
  • "Team dashboard" — A metrics and status dashboard for small teams

Store as appPrompt.

0.2 App Name

Ask [App name]: "What's the app name? (used for subdomain + database)"

  • "Derive from prompt" — Generate a URL-safe slug automatically
  • "Let me specify" — I'll type my own name

If "Derive from prompt": generate URL-safe slug (lowercase, hyphens, max 30 chars). Store as appName.

0.3 AI Features (conditional)

Scan appPrompt for AI keywords: "chatbot", "chat with AI", "summarize", "generate", "analyze", "AI-powered", "intelligent".

If detected: Ask [AI features]: "Does this app need AI features?"

  • "Yes — I have an OpenRouter key" — I'll paste my API key
  • "Yes — I need to get one" — I'll sign up at openrouter.ai
  • "No AI needed" — Skip AI capabilities

If yes: check grep OPENROUTER_API_KEY ~/.vibes/.env. If found, offer reuse (mask key). Otherwise collect via Ask and offer to cache to ~/.vibes/.env. Store as openRouterKey (or null if no AI).

0.4 SaaS Config

Factory config is collected here but applied later by the assembly script. Do NOT hand-implement SaaS logic — the factory assembly handles tenant routing, auth gating, and billing.

Choose billing mode based on monetization intent:

  • "off" (free) — all authenticated users get full access. Good for MVPs and internal tools.
  • "required" (subscription) — users must subscribe. Stripe billing integration is phase 2.

Always ask the user — do not assume a default.

Ask [Billing]: "What billing mode for your SaaS?" AND [Title]: "App display title?"

  • Billing: "Free (no billing)" or "Subscription required"
  • Title: "Derive from app name" or "Let me specify"

Ask [Tagline]: "Describe your app's tagline (short punchy phrase)"

  • "Generate one" — Create from app description
  • "Let me write it" — I'll provide it

When billing is "required": These fields appear on a pricing section visible to potential customers before signup. Optimize for marketing copy quality — benefit-driven language, not technical descriptions. Tagline = sales headline. Subtitle = value proposition ("why should I pay?"). Features = compelling benefit statements (3-5 items).

Repeat pattern for subtitle and features list (3-5 bullet points).

Store: billingMode ("off"/"required"), appTitle, tagline, subtitle, features (JSON array).

0.5 Theme Selection

Theme switching is handled by the live preview wrapper, not inside the app. The builder generates a single-theme layout. Set themeCount = 1.


Phase 1: Build

1.1 Setup
  1. Resolve plugin root — use this in all bash blocks:
    bash
    VIBES_ROOT="${CLAUDE_PLUGIN_ROOT:-$(dirname "$(dirname "${CLAUDE_SKILL_DIR}")")}"
  2. Create team: TeamCreate("launch-{appName}", "Full SaaS pipeline for {appName}")
  3. Create tasks: T1 (generate app.jsx), T3 (assembly), T4 (deploy), T5 (verify).
1.2 Spawn Builder (T1)
  1. Read ${CLAUDE_SKILL_DIR}/prompts/builder.md
  2. Substitute: {appPrompt}, {appName}, {pluginRoot}
  3. Set {aiInstructions}: if openRouterKey is set, add rule about useAI hook (see vibes SKILL.md "AI Features"). If null, leave empty.
  4. Spawn: Task tool, team_name="launch-{appName}", name="builder", subagent_type="general-purpose"

While the builder generates, SaaS config was already collected in Phase 0. Nothing else needs to happen in parallel — no credential collection, no manual setup.


Phase 2: Assembly & Deploy

Blocked by T1. Check TaskList until builder completes.

2.1 Verify Inputs

Confirm: app.jsx exists with valid JSX. All factory config values collected.

Scan app.jsx for builder mistakes (see LAUNCH-REFERENCE.md "Common Builder Mistakes"). Fix any found before proceeding.

2.2 Preview Before Deploy

Ask [Preview]: "Want to preview the app before deploying?"

  • "Yes — open live preview" — Start the preview server and iterate on the design
  • "No — deploy now" — Skip preview, go straight to deploy

If yes: run bun "$VIBES_ROOT/scripts/server.ts" and tell the user to open http://localhost:3333. They can chat to iterate on the design and switch themes. When satisfied, stop the server and continue to 2.3.

2.3 Assemble & Deploy

Step A — Assemble:

bash
VIBES_ROOT="${CLAUDE_PLUGIN_ROOT:-$(dirname "$(dirname "${CLAUDE_SKILL_DIR}")")}"
bun "$VIBES_ROOT/scripts/assemble-factory.js" app.jsx index.html \
  --app-name "{appName}" \
  --app-title "{appTitle}" \
  --domain "{appName}.vibes.diy" \
  --billing-mode "{billingMode}" \
  --tagline "{tagline}" \
  --subtitle "{subtitle}" \
  --features '{featuresJSON}' \
  --admin-ids '[]'

Step B — Validate: grep -c '__VITE_\|__OIDC_\|__APP_' index.html — must be 0.

Step C — Deploy:

bash
VIBES_ROOT="${CLAUDE_PLUGIN_ROOT:-$(dirname "$(dirname "${CLAUDE_SKILL_DIR}")")}"
bun "$VIBES_ROOT/scripts/deploy-cloudflare.js" \
  --name "{appName}" \
  --file index.html \
  {aiKeyFlag}

Where {aiKeyFlag} = --ai-key "{openRouterKey}" if set, omitted if null.

On first deploy, the CLI opens a browser for Pocket ID login. The user signs in once and tokens are cached for future deploys.


Phase 3: Verify & Cleanup

3.1 Verify

Ask [Verify]: "Your app is live! Open each URL and verify:\n\n- Landing: https://{appName}.vibes.diy\n- Tenant: https://{appName}.vibes.diy?subdomain=test\n\nDoes everything look right?"

  • "All working" — Everything loads correctly
  • "Something's broken" — Need to troubleshoot

If broken, ask what's wrong and troubleshoot.

3.2 Shutdown

Send shutdown_request to "builder" (if spawned). Wait for response. Clean up team.

3.3 Summary
## Launch Complete

**App**: {appTitle}
**URL**: https://{appName}.vibes.diy

When should I use Launch?

Launch fits situations like: the user wants to build and ship a complete SaaS product in one step; build and deploy.

How do I install Launch in Claude Code?

Run `npx skills add popmechanic/VibesOS --skill launch -a claude-code`. Or copy the skill folder (skills/launch in popmechanic/VibesOS) into .claude/skills/launch in your project. Claude Code loads it when a task matches its description.

How do I install Launch in Codex?

Run `npx skills add popmechanic/VibesOS --skill launch -a codex`. Or copy the skill folder (skills/launch in popmechanic/VibesOS) into .agents/skills/launch in your project. Codex loads it when a task matches its description.

Can I use Launch in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add popmechanic/VibesOS --skill launch -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/launch, .gemini/skills/launch, .github/skills/launch and .opencode/skills/launch in your project.

What does Launch need to run?

Going by SKILL.md and its folder, Launch needs the command-line tools its instructions call (bun) and credentials named OPENROUTER_API_KEY. Our summary lists: A credential in OPENROUTER_API_KEY. Its frontmatter pre-approves these tools: Read, Write, Edit, Bash, Glob, Grep, AskUserQuestion, Task, Teammate, SendMessage, TaskCreate, TaskUpdate, TaskList, TaskGet. Compatibility (from SKILL.md): Requires Claude Code with Agent Teams support.

Does Launch access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Launch safe to install?

Our automated static check of SKILL.md found notes only (mentions a .env file; pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Launch use?

Launch is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Launch use?

About 3k tokens (SKILL.md is roughly 12k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Launch?

Skills that share tags, products or a category with Launch: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 296k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
