This skill should be used when implementing Stripe webhook handlers in Next.js App Router with Supabase database integration. It applies when handling subscription lifecycle events, syncing payment status to a database, implementing upsert logic with fallback strategies, or sending transactional emails on payment events. Triggers on requests involving Stripe webhooks, subscription management, payment event handling, or Supabase subscriber tables.
Guides backend design work including API contract specification, database schema design, auth model, and integration point design. Use when designing the API, creating OpenAPI specs, designing database schemas, defining auth and permissions, or when the user says design the API, API contract, schema design, database design, backend design, OpenAPI spec. Requires completed Product Discovery and Product Design artifacts as input.
CO-STAR UI Creator for React/Next.js: structured prompting to build or integrate UI (components, pages, design systems) or to create custom CO-STAR prompts. Use when the user wants to add hero sections, dashboards, design tokens, shadcn/Magic UI/Aceternity integration, Newsprint design system, or to draft their own CO-STAR prompt (Context, Objective, Style, Tone, Audience, Response). Always run discovery questions first, then plan, then implementation.
Privacy-preserving ERC-4337 wallet development for vehicle identity and sensitive data protection. Use when implementing ERC-4337 account abstraction wallets that handle sensitive information (vehicle license plates, biometric data, personal IDs) requiring on-chain privacy. Triggers on requests like implement ERC-4337 wallet for vehicle, create privacy-protected account abstraction, build wallet with vehicle number privacy, develop ERC-4337 with ZK proof integration, or any smart contract wallet development requiring commitment schemes, deterministic address generation, and sensitive data protection.
Run fantasy baseball projection commands — predict, evaluate, compare systems, look up player projections/valuations, manage cached datasets, evaluate keeper league trades and optimization, run draft boards and mock drafts, and use Yahoo Fantasy integration for rosters, draft tracking, and keeper cost derivation. Use this when the user asks to run projections, compare systems, evaluate accuracy, look up a player, check valuations, manage/rebuild cached datasets, evaluate keeper league decisions/trades/optimization, view draft boards, run mock drafts, sync Yahoo league data, or manage Yahoo-derived keeper costs.
