mcp-integration
lunarpulse
Use Model Context Protocol servers to access external tools and data sources. Enable AI agents to discover and execute tools from configured MCP servers (legal databases, APIs, database connectors, weather services, etc.).
Swift Concurrency Expert Guide
mosif16
"Deep dive into Swift's async/await runtime, Sendable enforcement, actors, and migration strategies."
architecture-monolith
KentoShimizu
"Modular monolith architecture workflow for strong domain boundaries, transactional consistency, and operational simplicity in a single deployable. Use when teams need fast delivery and coherent data consistency with controlled complexity; do not use when independent runtime scaling boundaries are mandatory."
db-migration-strategy
KentoShimizu
"Schema migration strategy workflow for sequencing changes, compatibility windows, and rollback-safe rollout in live systems. Use when schema evolution impacts running services; do not use for static greenfield schemas without deployment constraints."
db-query-optimization
KentoShimizu
"Query optimization workflow for reducing latency and resource cost through plan-aware rewrites and access-path improvements. Use when hot-path query behavior is the bottleneck; do not use for conceptual schema redesign without workload evidence."
db-index-strategy
KentoShimizu
"Index strategy workflow for balancing read latency, write amplification, and plan stability on critical query paths. Use when query performance depends on index design trade-offs; do not use for high-level conceptual modeling."
Agent Tool Builder
mayurrathi
"Tools are how AI agents interact with the world. A well-designed tool is the difference between an agent that works and one that hallucinates, fails silently, or costs 10x more tokens than necessar..."
mercadopago-integration
martinacostadev
Integrate MercadoPago Checkout Pro (redirect-based) into Next.js applications with any PostgreSQL database (Supabase, AWS RDS, Neon, PlanetScale, self-hosted, Prisma, Drizzle, or raw pg). Use when the user needs to: (1) Add MercadoPago payment processing to a Next.js app, (2) Create a checkout flow with MercadoPago, (3) Set up payment webhooks for MercadoPago, (4) Build payment success/failure pages, (5) Create a shopping cart with payment integration, (6) Troubleshoot MercadoPago integration issues (auto_return errors, webhook failures, hydration mismatches, double submissions). Triggers on requests mentioning MercadoPago, Mercado Pago, payment integration with MP, Argentine/Latin American payment processing, or checkout with MercadoPago. Supports all MercadoPago countries: Argentina (ARS), Brazil (BRL), Mexico (MXN), Colombia (COP), Chile (CLP), Peru (PEN), Uruguay (UYU). This skill is a code-generation template — it does NOT execute financial transactions. All generated code is presented for human review and requires explicit user approval before being written to disk. Financial code templates are stored in reference files and are never auto-executed.
webdev-filter-query-builder
ozten
Domain-specific filter query building with AST representation, operator handling, query serialization, and field-type-specific inputs. Use when building advanced filter UIs for observability tools, data analytics, search interfaces, or any system requiring structured query construction with boolean logic, comparison operators, and URL/string serialization.
db-replication-sharding
KentoShimizu
"Replication and sharding workflow for scaling read/write throughput while managing consistency, failover, and data distribution risk. Use when single-node limits are reached or resilience requires topology changes; do not use for local query tuning only."
architecture-clean-architecture
KentoShimizu
"Clean Architecture workflow for enforcing dependency direction, stable domain boundaries, and use-case-centered application design. Use when teams must separate business rules from frameworks and delivery mechanisms; do not use for isolated module cleanup without boundary implications."
db-logical-design
KentoShimizu
"Logical database design workflow for table structure, key strategy, constraints, and relational consistency. Use when durable schema semantics must be defined before physical tuning; do not use for query-only optimization tasks."
db-conceptual-modeling
KentoShimizu
"Conceptual data modeling workflow for domain entities, relationships, and lifecycle boundaries. Use when teams must align on domain meaning before logical/physical schema decisions; do not use for index-only or migration-only tasks."
db-normalization
KentoShimizu
"Normalization workflow for reducing update anomalies while balancing query practicality and domain invariants. Use when schema redundancy and inconsistency risk need deliberate trade-off decisions; do not use for physical indexing-only tasks."
effect-testing
front-depiction
Write comprehensive tests using @effect/vitest for Effect code and vitest for pure functions. Use this skill when implementing tests for Effect-based applications, including services, layers, time-dependent effects, error handling, and property-based testing.
context-witness
front-depiction
Decide between Context Tag witness and capability patterns for dependency injection, understanding coupling trade-offs
sql-cli
Interstellar-code
Token-efficient MySQL/PostgreSQL operations using mycli and native CLI tools (Windows/Mac/Linux compatible). Replaces Artisan Tinker for database queries with 87% token savings.
layer-design
front-depiction
Design and compose Effect layers for clean dependency management
service-implementation
front-depiction
Implement Effect services as fine-grained capabilities avoiding monolithic designs
mongodb-transactions-consistency
romiluz13
MongoDB transaction correctness, consistency, and retry safety. Use when implementing multi-document writes, debugging transaction failures, choosing readConcern/writeConcern, handling TransientTransactionError or UnknownTransactionCommitResult, or deciding when transactions are required. Triggers on "transaction", "withTransaction", "session", "read concern", "write concern", "causal consistency", "snapshot", "retry commit", "ACID", "TransientTransactionError", and "UnknownTransactionCommitResult".
effect-ai-language-model
front-depiction
Master the Effect AI LanguageModel service for text generation, structured output, streaming, and tool calling. Use when working with LLM interactions, schema-validated responses, or building conversational AI systems.
domain-predicates
front-depiction
Generate comprehensive predicates and orders for domain types using typeclass patterns
effect-ai-tool
front-depiction
Define and implement AI tools using @effect/ai's Tool and Toolkit APIs. Use when building LLM integrations with type-safe tool definitions, parameter validation, and handler implementations. Covers user-defined tools, provider-defined tools, and toolkit composition.
