Hypervibe

🇫🇷 Lire en français

A Claude Code plugin that bootstraps full-stack T3 projects with modular addons. Built for non-technical users who want to create and deploy web apps by describing what they want in plain language.

📘 First time? Follow the step-by-step installation guide. It walks you through the prerequisites, the accounts to create, and your first project, end to end.

Installation

You need Claude Code first. It is included with a Claude Pro plan or higher (the free plan is not enough), and ships with the Claude desktop app (Mac and Windows) or as a CLI. New to Claude? Create your account and subscribe here. Then, inside Claude Code, run:

/plugin marketplace add flavien-ia/hypervibe-harness
/plugin install hypervibe@hypervibe-harness

Updating from a version older than 2.5? After updating the plugin, just re-run /start in Claude Code: it detects your old background mechanisms and consolidates them into the new unified one for you, safely and with your consent at each step (nothing happens if you have nothing to migrate). More context in MIGRATION.md.

Then type /start: it installs everything else for you (Node.js, pnpm, Git, and each service's CLI) and checks that all your connections work.

Prefer a guided, click-by-click version? See the full walkthrough at hypervibe.fr/plugin/installation.

Getting started

New to this?	Already comfortable?
/start - checks your setup and shows you around	/bootstrap - jump straight in
/prof - explains how everything works	/spec - build a detailed spec first

How it works

Just describe what you want to build. Claude analyzes your description and infers which addons are needed (database, auth, payments, etc.), then presents the plan for your approval before building.

/bootstrap My photographer portfolio website
/bootstrap My lead management dashboard with user accounts
/bootstrap My online invoicing SaaS with Stripe payments

Three ways to define your project

When you launch /bootstrap, you choose how to describe your app:

• A - Build a spec together (/spec): Claude guides you step by step through 5 blocks (project, pages, design, features, constraints) and produces a cahier-des-charges.md
• B - Provide an existing spec: give Claude a .md file, he reads it and infers the infrastructure
• C - Short description only: Claude asks the infrastructure questions in one go and builds a simple app

Workflow skills

Skill	What it does
/bootstrap	Create a new project from scratch
/spec	Build a detailed project specification, step by step
/start	First-time onboarding: checks prerequisites, presents all commands
/prof	Explains how everything works in plain language (pedagogical mode)
/seo	Audit SEO and fix issues (metadata, sitemap, OG, structure, URLs/slugs, accessibility, readability, topical depth, freshness)
/geo	Audit and optimize for AI answer engines (ChatGPT, Claude, Perplexity, Google AI Overviews) - llms.txt, AI crawler policy, FAQPage schema, citability signals, E-E-A-T, Q&A format. Complementary to /seo.
/gsc	Connect the site to Google Search Console, verify DNS automatically, submit the sitemap, then audit what Google actually sees - indexing coverage, top queries, quick wins (positions 11-20), low CTR pages, zombie pages. Complementary to /seo (external Google data).
/security	Security audit (secrets, auth, headers, dependencies, RGPD)
/rgpd-audit	RGPD compliance audit - detects third-party services in use, updates the subprocessors registry, generates or refreshes the privacy policy page
/clean	Find unused files, dead code, orphan env vars and DB tables - review + delete on a branch
/rotate-secret	Rotate a secret (Stripe, Brevo, Google…) everywhere it lives - local + Vercel
/quotas	Show your current usage against each service's free tier (Neon, Cloudflare, Brevo, Resend, Vercel) with verdicts per gauge

Each addon can be activated during /bootstrap or used standalone on an existing project.
