new-app

new-app is a skill for Claude Code, Codex from OneWave-AI/open-agent-stack. It costs 57 tokens per session (598 once invoked), scanned A, original, MIT.

A starter workflow for building a new web app with Next.js, TypeScript, and Tailwind CSS. It applies a chosen visual theme and leaves clear connection points for login and data storage.

In plain words
What is it for?
Use it to begin a marketing site, dashboard, tool, storefront, prototype, or client project with a consistent foundation.
Why use it?
It avoids starting with generic styling, an unclear folder structure, or fake data and unfinished login code that later need replacing.

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.

Security

Grade A, and why

new-app 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 25 lines — stays where its author put it; the contents beside it link to each section on GitHub.

New App

The first hour sets the ceiling: apps that start as default-Tailwind boilerplate stay looking like it. Scaffold with the design system already in, the structure already opinionated, and the lies already removed (no fake data wired to nothing).

Workflow

  1. One question round, maximum. From the idea sentence, infer the app shape (marketing site, dashboard, tool, storefront) and confirm only what changes the scaffold: does it need auth, does it need a database, who is it for. Everything else gets a sensible default now and a refactor later.
  2. Pick the skin. Choose (or let the user choose) a theme from the Open Agent Stack design-styles/ collection -- aurora-mesh, cirrus, liquid-glass, mono-brutalist, neo-terminal, sand-terra, tidal -- and wire its tokens into Tailwind before writing any component. House rules apply regardless of theme: no purple, no emoji in UI, icons from Lucide.
  3. Scaffold. Next.js App Router + TypeScript + Tailwind. Structure: route groups by audience, components/ui for primitives consuming tokens only, lib for real logic. Auth slot (middleware + provider stub wired to real session shape) and data slot (typed client, one real example query) if needed -- stubs that state what they are, never mock data pretending to be live.
  4. Set the motion language. Run motion-system before the first animated component -- three durations, three easings, and the reduced-motion policy go into the theme alongside the color tokens. Ten minutes here is what stops the app accumulating fourteen different hover durations by week two.
  5. First real screen. Build the landing/home screen properly against the theme -- type scale, spacing, one signature motion -- so every screen after has a quality bar to match, not a placeholder to excuse.
  6. Boot it. npm run dev, verify it renders, commit. The scaffold is done when it runs, not when the files exist.

Rules

  • Never ship hardcoded/mock data wired to look live -- if a real backend exists, query it; if not, the empty state is the honest UI.
  • Tokens from minute one: no raw hex in components, ever, so the theme swap stays a one-file change.
  • Opinionated beats configurable at this stage -- one good default now, options when the app earns them.
  • The README the scaffold writes says what is real, what is stubbed, and what the next three build steps are.

What this file has done since we first saw it

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.
