User-centered problem framing that captures who is blocked, what they're trying to do, why it matters, and how it feels. \n \n Structures problems around five dimensions: persona, desired outcomes, barriers, root causes, and emotional impact—ensuring you solve problems worth solving, not feature requests \n Includes a fill-in template, quality checks, and anti-patterns to avoid solution smuggling, generic personas, and symptom-level diagnosis \n Designed for discovery alignment, stakeholder buy-

Local network Sonos speaker control with discovery, playback, volume, and grouping. \n \n Discover speakers on the local network and control individual devices by name with play, pause, stop, and volume commands \n Manage speaker groups with join, unjoin, party, and solo operations; browse and play favorites and queue tracks \n Optional Spotify search integration via SMAPI (requires Spotify Web API credentials) and fallback IP specification for SSDP discovery failures \n Requires the sonos CLI b

Structure vague product requests into validated opportunities and testable solutions before building. \n \n Guides teams through a five-question discovery process: extract desired outcome, identify customer problems (opportunities), generate solution ideas, evaluate feasibility and impact, and select a proof-of-concept to test first \n Prevents \"feature factory\" syndrome by forcing divergence across multiple opportunities and solutions before converging on what to build \n Outputs a structured

Expert patterns for building Shopify apps with React Router, embedded Admin integration, and GraphQL APIs. \n \n Covers React Router app setup, embedded apps with App Bridge, and secure webhook handling with HMAC verification \n Emphasizes GraphQL Admin API over REST for new development, with guidance on rate limiting and async processing patterns \n Includes anti-patterns to avoid: REST API usage, synchronous webhook processing, and polling instead of webhooks \n Highlights critical sharp edges

Generate type-safe Convex queries, mutations, and actions with built-in validation, authentication, and error handling. \n \n Supports three function types: queries (read-only, cached), mutations (transactional writes with automatic retries), and actions (external APIs, long-running tasks) \n Enforces argument and return type validation via Convex validators; includes authentication checks and authorization patterns for ownership verification \n Actions requiring Node.js APIs (SDKs, crypto) must

Performance optimization patterns for Mapbox GL JS applications, prioritized by user impact. \n \n Eliminate initialization waterfalls by loading map data in parallel with map initialization, and set precise viewport to avoid redundant tile fetches \n Use symbol layers for 100+ markers (GPU-accelerated) and clustering for 10,000+ features; avoid HTML markers at scale \n Choose GeoJSON for datasets under 5 MB, vector tiles for 20+ MB; implement viewport-based loading to reduce bandwidth \n Always

TypeScript-first schema validation with automatic static type inference from runtime schemas. \n \n Define schemas once and automatically infer TypeScript types for compile-time safety; supports primitives, objects, arrays, unions, and recursive types \n Validate data with parse() (throws) or safeParse() (returns result object); includes async validation for database lookups and external checks \n Transform and refine data during validation using transform() , refine() , and superRefine() for cu

Diagnose and fix real problems. Every command here is tested and works.

Holistic SaaS health assessment across growth, retention, unit economics, and capital efficiency. \n \n Evaluates four interconnected dimensions—growth & retention, unit economics, capital efficiency, and strategic position—against stage-specific benchmarks (pre-$10M, $10M–$50M, $50M+ ARR) \n Identifies red flags by severity (critical, high priority, medium priority) and surfaces root causes rather than isolated metric problems \n Delivers a prioritized action plan with expected impact, fro
