You are an expert QA auditor specializing in comprehensive Flutter application audits for production readiness, compliance certification, and enterprise deployment. This skill performs deep audits covering architecture, security, compliance, testing, performance, and code quality.

Refactor sync+async modules to eliminate duplication using the iter-coroutine

Multi-LLM collaborative brainstorming and planning. Use when user explicitly requests consultation with multiple AI models (ChatGPT, Gemini, other LLMs) before presenting an implementation plan, or asks to "consult the council", "ask other models", or "get perspectives from other AIs". Queries external LLM APIs, synthesizes their perspectives, and presents an adapted implementation plan.

Use when testing web applications, debugging browser console errors, automating form interactions, or verifying UI implementations. Load for localhost testing, authenticated app testing (Gmail, Notion), or recording demo GIFs. Requires Chrome extension 1.0.36+, Claude Code 2.0.73+, paid plan.

Dual-AI engineering loop orchestrating Claude Code (planning/implementation) and Codex (validation/review). Use when (1) complex feature development requiring validation, (2) high-quality code with security/performance concerns, (3) large-scale refactoring, (4) user requests codex-claude loop or dual-AI review. Do NOT use for simple one-off fixes or prototypes.

Generate ROS 2 Python launch files and multi-node system configurations for educational content. This skill should be used when creating lessons that teach launch file syntax, writing exercises involving multi-node startup, parameter configuration, or generating worked examples for robot system deployment.

Guidelines for multi-agent AI and learning projects with lesson-based structures. Activate when working with AI learning projects, experimental directories like .spec/, lessons/ directories, STATUS.md progress tracking, or structured learning curricula with multiple modules or lessons.

UniTask library expert specializing in allocation-free async/await patterns, coroutine migration, and Unity-optimized asynchronous programming. Masters UniTask performance optimizations, cancellation handling, and memory-efficient async operations. Use PROACTIVELY for UniTask implementation, async optimization, or coroutine replacement.

Expert help with GitHub CLI (gh) for managing pull requests, issues, repositories, workflows, and releases. Use this when working with GitHub operations from the command line, creating new releases, or bumping package versions.

GPU VRAM management patterns for sharing memory across services (Ollama, Whisper, ComfyUI). OOM retry logic, auto-unload on idle, and service signaling protocol.

Build production-ready component libraries with Tailwind CSS using CVA, compound components, design tokens, and theming.

Create persona documentation for a product or codebase. Use when asked to create persona docs, document target users, define user journeys, document onboarding flows, or when starting a new product and needing to define its audience. Persona docs should be the first documentation created for any product.

Rate limiting algorithms, implementation strategies, HTTP conventions, tiered limits, distributed patterns, and client-side handling. Use when protecting APIs from abuse, implementing usage tiers, or configuring gateway-level throttling.

When the user asks about startup metrics, SaaS metrics, unit economics, or business performance tracking. Triggers on: "startup metrics", "SaaS metrics", "CAC and LTV", "unit economics", "burn multiple", "rule of 40", "magic number", "marketplace metrics", "churn rate", "MRR", "ARR", "net revenue retention", "runway", or requests for metrics dashboards and investor reporting.

Minimize total codebase size through ruthless simplification. Measure success by final code amount, not effort. Bias toward deletion.

Build flexible, maintainable React components using compound components, context providers, and explicit variants. Avoid boolean prop proliferation.

Patterns for building resilient API clients and real-time connections with retry logic, circuit breakers, and graceful degradation. Use when building production systems that need to handle failures. Triggers on retry logic, circuit breaker, connection resilience, exponential backoff, API client, fault tolerance.

React and Next.js performance optimization guidelines from Vercel Engineering. 57 rules across 8 categories for writing, reviewing, and refactoring React code.

Patterns for skeleton loaders, shimmer effects, and loading states that match design system aesthetics. Covers skeleton components, shimmer animations, and progressive loading. Use when building polished loading experiences. Triggers on skeleton, loading state, shimmer, placeholder, loading animation.

API versioning strategies — URL path, header, query param, content negotiation — with breaking change classification, deprecation timelines, migration patterns, and multi-version support. Use when evolving APIs, planning breaking changes, or managing version lifecycles.
