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

scaffold-nextjs 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 2mo 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.

What it actually says

Scaffold Next.js Project (claudeforge)

Follow the master prompt at frontend/nextjs/PROMPT.md. Steps:

  1. Confirm parameters: project_name, project_slug (kebab-case), app type (web/admin/landing/chat), include 3D/auth, brand primary color, deployment target (vercel vs self-hosted).
  2. Read foundational docs:
    • frontend/nextjs/PROMPT.md — master prompt with directory tree, deps, key files
    • frontend/nextjs/01-stack-and-libraries.md — locked library list with rationale
    • frontend/nextjs/02-design-system-spec.md — token system if creating a design system
  3. Read deep-dives as needed:
    • 03-animations-and-motion.md — Framer Motion patterns
    • 04-mobile-responsive.md — mobile-first, dvh, safe-area, touch targets
    • 05-forms-and-state.md — rhf+zod, TanStack Query, Zustand, URL state
  4. Generate: pnpm create next-app with TS+Tailwind+ESLint+src-dir+App Router, replace deps with locked stack, init shadcn/ui, install initial UI components (button/input/label/dialog/dropdown/toast), write layout.tsx, providers.tsx, globals.css with token CSS vars, tailwind.config.ts with semantic tokens, lib/utils.ts (cn), lib/env.ts (zod), one example feature page demonstrating Server Component + form + TanStack Query mutation.
  5. Verify: pnpm dev works, pnpm lint && pnpm type-check && pnpm test clean.
  6. If deployment_target=self-hosted: also create Dockerfile with output: 'standalone' (see deployment/per-framework/deploy-nextjs.md).

Do NOT install antd, Mantine, react-icons, formik, lenis, ogl, or any rejected library from 01-stack-and-libraries.md section 7.

Changes

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.
