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

senior-frontend 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 6d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/bundle_analyzer.py, scripts/component_generator.py, scripts/frontend_scaffolder.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Description

Production-grade frontend development patterns, performance optimization, and modern ecosystem integrations for React 19 / Next.js 15 applications with Tailwind CSS v4 and TypeScript. Covers React 19 Compiler, Partial Prerendering (PPR), View Transitions API, and SPA/MPA hybrid strategies.

Orchestration & Integration

  • ui-components-expert: For building robust UI components (Radix, shadcn).
  • tailwind-expert: For styling and custom @theme configurations.
  • nextjs-app-router-expert: For RSC, caching, and Next.js routing patterns.
  • state-management-expert: For client-side state (Zustand, Jotai).
  • tanstack-query-expert: For advanced data fetching and server state caching.
  • spa-orchestrator: For Single-Page Application architectures.
  • mpa-orchestrator: For Multi-Page Application architectures.

Trigger Conditions

  • Scaffold a new React or Next.js 15 project with TypeScript and Tailwind CSS v4.
  • Generate new components, custom hooks, or Server Actions.
  • Analyze and optimize bundle sizes and Core Web Vitals.
  • Implement advanced React 19 patterns (useActionState, useOptimistic, use()).
  • Build SPAs — coordinate with spa-orchestrator.
  • Ensure accessibility compliance (WCAG 2.2) and testing.

Technical Guidelines & Best Practices

1. Next.js 15: Server vs Client Components

Use Server Components by default for performance and SEO. Use 'use client' strictly for:

  • State (useState, useEffect), event handlers (onClick), browser APIs.
  • Interactive UI needing client hydration.

Next.js 15.2+ Requirements:

  • Await Promise-based params and searchParams before accessing properties.
  • Use Partial Prerendering (PPR) natively. Wrap dynamic sections in <Suspense>.
2. React 19 Compiler & Hooks

Do not use useMemo, useCallback, or React.memo unless explicitly required; rely on the React 19 compiler.

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.
