What is web-app-scaffold?

A skill for starting full-stack web applications with Next.js, TypeScript, MongoDB, and other listed development tools. Full-stack means it covers both the user interface and server-side code.

Use it to scaffold a new web app, including its application structure, data access, interface components, validation, and tests.

It removes the initial setup work needed to assemble a new application with these technologies.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00081	$0.01492
Opus 5	$0.00041	$0.00746
Sonnet 5	$0.00016	$0.00298
Haiku 4.5	$0.00008	$0.00149

Security

Grade A, and why

web-app-scaffold scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Scaffold a fullstack Next.js app

Database default is PostgreSQL via Drizzle; use MongoDB/Mongoose when the user asks for it or the domain is genuinely document-shaped.

Steps

Create the app (confirm the name first):

pnpm create next-app@latest <name> --typescript --tailwind --eslint --app --src-dir --import-alias "@/*" --use-pnpm

Install the stack:

# Postgres (default)
pnpm add drizzle-orm pg zod @tanstack/react-query
pnpm add -D drizzle-kit @types/pg @electric-sql/pglite \
  vitest @vitejs/plugin-react @testing-library/react @testing-library/jest-dom jsdom \
  @tanstack/react-query-devtools @tanstack/eslint-plugin-query
# Mongo variant: swap drizzle-orm/pg/drizzle-kit/@types/pg/@electric-sql/pglite
# for: mongoose (dep) + mongodb-memory-server (dev)
pnpm dlx shadcn@latest init            # then: pnpm dlx shadcn@latest add button card ...
pnpm dlx shadcn@latest mcp init --client claude   # writes .mcp.json (commit it)

The MCP server lets Claude browse, search, and install components from any shadcn-compatible registry (including third-party ones) by name — no API key needed. See "Registries and MCP" in the shadcn-ui skill.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
