Playwright Blazor Testing

Best practices for building Harper applications, covering schema definition, automatic APIs, authentication, custom resources, and data handling. Triggers on tasks involving Harper database design, API implementation, and deployment.

Generates folder structures, module contracts, middleware pipelines, and frontend/backend boundaries for TypeScript full-stack applications, and finds domain-informed deepening opportunities in existing codebases. Use when setting up project structure, organizing a monorepo, defining folder layout, designing backend modules, establishing team conventions, improving architecture outside a local diff, writing an architecture brief, or asking "how should I structure this app", "design the folder structure", "set up the architecture", "find architecture improvements", "make this codebase agent-friendly", or "set up guardrails for coding agents". For scaffolding a new Next.js repo use scaffold-nextjs, for a new TypeScript CLI use scaffold-cli, for multi-tenant domain or isolation strategy use multi-tenant-architecture, and for structural review of a local diff use pr-reviewer.

Deploy Hummingbot trading infrastructure including API server, MCP server, and Condor Telegram bot. Use this skill when the user wants to install, deploy, set up, or configure Hummingbot.

Use this skill when adding authentication, handling user input, working with secrets, creating API endpoints, or implementing payment/sensitive features. Provides comprehensive security checklist and patterns.

Use this skill whenever the user asks about weather, forecasts, temperature, rain, storms, severe weather alerts, air quality, pollen, UV, or wants an activity recommendation (can I walk / bike / hike / commute / drive given the weather). Weather CLI powered by Open-Meteo (global, no auth, unlimited) + NWS (US severe weather). No API key. Triggers on phrasings like 'what's the weather', 'is it going to rain today', 'any storms coming', 'should I bike to work', 'how's the air quality', 'compare NYC and LA weather this weekend', 'is this unusually hot for April'.

Execute read-only SQL queries against multiple Microsoft SQL Server databases. Use when: (1) querying MSSQL/SQL Server databases, (2) exploring database schemas/tables, (3) running SELECT queries for data analysis, (4) checking database contents. Supports multiple database connections with descriptions for intelligent auto-selection. Blocks all write operations (INSERT, UPDATE, DELETE, DROP, etc.) for safety.
