frontend-feature is a skill for Claude Code from vstorm-co/full-stack-ai-agent-template. It costs 64 tokens per session (701 once invoked), scanned A, original, MIT.

A project-specific guide for building pages and data-driven features in a Next.js frontend, a web application framework using React.

In plain words
What is it for?
It helps add localized dashboard or marketing pages, connect screens to backend endpoints, and manage interactive state with the project's existing conventions.
Why use it?
It explains where routes, data access, UI components, client state, and translations belong, reducing inconsistent frontend changes.

About the project

Full-Stack AI Agent Template generates full-stack AI applications with a FastAPI backend and Next.js frontend, including agents, retrieval-augmented generation, streaming, authentication, and integrations. It is for building AI products with features such as chat, conversation sharing, administration, and multiple agent or vector-database choices. Catalogue add-ons support the generated applications and their agent workflows.

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.

Security

Grade A, and why

frontend-feature 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 7d 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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Frontend Feature (Next.js 15 + React 19)

The frontend lives in frontend/src/ — App Router, TypeScript, Tailwind, next-intl, and Zustand. Routes are locale-prefixed: app/[locale]/….

Layout

Path Purpose
src/app/[locale]/… Pages (route groups: (dashboard), (marketing), (auth))
src/app/api/… Next.js route handlers that proxy to the backend
src/lib/ API clients (api-client.ts, *-api.ts), query-keys.ts, helpers
src/components/ UI by domain (chat/, kb/, dashboard/, ui/, …)
src/stores/ Zustand stores (one per concern, re-exported from index.ts)
src/hooks/ useChat, useWebSocket, etc.

Steps

  1. Page — add src/app/[locale]/(dashboard)/<feature>/page.tsx. Default to a Server Component; add "use client" only where you need interactivity. Read params via the async App Router APIs.

  2. Data access — add a typed client in src/lib/<feature>-api.ts built on api-client.ts. Don't scatter fetch calls in components. For server-side fetching use server-api.ts. If the backend needs a same-origin proxy (auth cookies), add a handler under src/app/api/….

  3. Caching keys — register query keys in src/lib/query-keys.ts so cache invalidation stays consistent.

  4. Client state — if the feature needs shared client state, add a store in src/stores/<feature>-store.ts and export it from stores/index.ts. Keep server data in the data layer; use stores for UI/ephemeral state.

  5. Components — put reusable pieces in src/components/<domain>/; compose primitives from src/components/ui/. Keep components under ~100 lines — extract when they grow.

  6. i18n — user-facing copy goes through next-intl messages, not hardcoded strings. Add keys to the message catalog and read them with useTranslations / getTranslations.

  7. Verify:

    cd frontend
    bun run type-check && bun run lint
    bun dev            # check the page renders against a running backend (make dev)

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.
