Generate database seed scripts with realistic sample data. Reads Drizzle schemas or SQL migrations, respects foreign key ordering, produces idempotent TypeScript or SQL seed files. Handles D1 batch limits, unique constraints, and domain-appropriate data. Use when populating dev/demo/test databases. Triggers: 'seed database', 'seed data', 'sample data', 'populate database', 'db seed', 'test data', 'demo data', 'generate fixtures'.
Expert Go developer specializing in Go 1.21+ features, concurrent programming with goroutines and channels, and comprehensive stdlib utilization. This agent excels at building high-performance, concurrent systems with idiomatic Go patterns and robust error handling.
Generate and review Java code using patterns and best practices from Joshua Bloch's "Effective Java" (3rd Edition). Use this skill whenever the user asks about Java best practices, API design, object creation patterns, generics, enums, lambdas, streams, concurrency, serialization, method design, exception handling, or writing clean, maintainable Java code. Trigger on phrases like "Effective Java", "Java best practices", "builder pattern", "static factory", "defensive copy", "immutable class", "enum type", "generics", "bounded wildcard", "PECS", "stream pipeline", "optional", "thread safety", "serialization proxy", "checked exception", "try-with-resources", "composition over inheritance", "method reference", "functional interface", or "Java API design."
Master Rust 1.75+ with modern async patterns, advanced type system features, and production-ready systems programming. Expert in the latest Rust ecosystem including Tokio, axum, and cutting-edge crates. Use PROACTIVELY for Rust development, performance optimization, or systems programming.
Node.js development principles and decision-making. Framework selection, async patterns, security, and architecture. Teaches thinking, not copying.
Comprehensive AEM (Adobe Experience Manager) architecture design skill for enterprise implementations. Use this skill when building AEM components, designing content architecture, configuring Dispatcher caching, creating dialogs with Granite UI, implementing Sling Models, OSGi services, servlets, or ClientLibs. Covers component development, performance optimization, caching strategies, security best practices, and CI/CD with Cloud Manager. Supports both AEM 6.5 and AEM as a Cloud Service. Also creates architecture diagrams (Mermaid, ASCII) for AEM systems. Triggers on requests for AEM development guidance, component creation, dialog design, caching configuration, architectural decisions, or diagram/visualization requests for AEM projects.
Terra API webhook handling for real-time health data. Use when setting up webhook endpoints, verifying signatures, handling events, or debugging webhook issues.
Add Stripe payments to a web app — Checkout Sessions, Payment Intents, subscriptions, webhooks, customer portal, and pricing pages. Covers the decision of which Stripe API to use, produces working integration code, and handles webhook verification. No MCP server needed — uses Stripe npm package directly. Triggers: 'add payments', 'stripe', 'checkout', 'subscription', 'payment form', 'pricing page', 'billing', 'accept payments', 'stripe webhook', 'customer portal'.
Creates and manages modular Filament plugins in Laravel. Use this skill whenever the user asks to create a plugin, module, package, or feature for Filament. This includes: creating a new plugin in the plugins/ directory, generating its ServiceProvider, registering it as a local Composer path package, creating the Artisan Install command, and — if the plugin has migrations — configuring loadMigrationsFrom() so they can be published or physically copied into the main project. Trigger this skill when the user says things like "add a billing module", "create an inventory plugin", "I need a new Filament module for X", or any request that implies encapsulated functionality in Filament.
Understand SpacetimeDB architecture and core concepts. Use when learning SpacetimeDB or making architectural decisions.
Configure and collect crash dumps for modern .NET applications. USE FOR: enabling automatic crash dumps for CoreCLR or NativeAOT, capturing dumps from running .NET processes, setting up dump collection in Docker or Kubernetes, using dotnet-dump collect or createdump. DO NOT USE FOR: analyzing or debugging dumps, post-mortem investigation with lldb/windbg/dotnet-dump analyze, profiling or tracing, or for .NET Framework processes.
Build with MPP (Machine Payments Protocol) - the open protocol for machine-to-machine payments over HTTP 402. Use when developing paid APIs, payment-gated content, AI agent payment flows, MCP tool payments, pay-per-token streaming, or any service using HTTP 402 Payment Required. Covers the mppx TypeScript SDK with Hono/Express/Next.js/Elysia middleware, pympp Python SDK, and mpp Rust SDK. Supports Tempo stablecoins, Stripe cards, Lightning Bitcoin, and custom payment methods. Includes charge (one-time) and session (streaming pay-as-you-go) intents. Make sure to use this skill whenever the user mentions mpp, mppx, machine payments, HTTP 402 payments, Tempo payments, payment channels, pay-per-token, paid API endpoints, or payment-gated services.
