Work with NFDomains (NFDs), the Algorand Name Service (.algo domains), using the @txnlab/nfd-sdk TypeScript SDK. Use when building features that involve resolving .algo domain names to addresses (or reverse), displaying NFD avatars and metadata, searching for NFDs, minting new NFDs, purchasing NFDs from the marketplace, managing NFD metadata and linked addresses, working with NFD segments (subdomains), interacting with NFD vaults, or integrating NFD name resolution into Algorand applications.
Drupal migration expertise. Use when working with D7-to-D10 migrations, CSV imports, JSON API imports, or custom migration plugins.
PostgreSQL query optimization, JSONB operations, advanced indexing strategies, partitioning, connection management, and database administration. Use this skill for PostgreSQL-specific optimizations, performance tuning, replication setup, and PgBouncer configuration.
REST API design and development expert specializing in endpoint design, HTTP semantics, versioning, error handling, pagination, and OpenAPI documentation. Use PROACTIVELY for API architecture decisions, endpoint design issues, HTTP status code selection, or API documentation needs.
OpenAPI documentation skill for Rust APIs using utoipa with Axum framework. Use when building REST APIs with automatic OpenAPI spec generation and Scalar UI. Covers: (1) ToSchema derive for request/response types, (2) #[utoipa::path] for endpoint documentation, (3) OpenApi derive for combining specs, (4) Security schemes (JWT, API keys), (5) IntoParams for query/path params, (6) Scalar UI integration, (7) Response and error handling patterns. Triggers: utoipa, openapi, scalar, axum api, ToSchema, IntoParams, rust api docs.
Production-grade API design patterns for REST, GraphQL, gRPC, and tRPC. Covers API architecture, OpenAPI/Swagger specs, versioning/deprecation, authentication/authorization, rate limiting, pagination, error models, contract testing, and developer documentation.
Debugs Laravel applications with Xdebug integration. Activates when setting breakpoints, stepping through code, inspecting variables, analyzing dd() output, debugging routes, controllers, queues, or Eloquent queries; or when user mentions debug, breakpoint, step into, inspect variables, Xdebug, or troubleshooting errors.
Go backend with Gin, MongoDB, JWT auth, and Clean Architecture.
Research MQL5 documentation (Japanese and English only) for MQL5 creation/editing issues, compile errors, or API questions. Use when users ask to look up docs, interpret MQL5 errors, or confirm correct language usage. Sources limited to https://www.mql5.com/ja/docs and https://www.mql5.com/en/docs.
Guide for cross-compiling complex C programs (like DOOM) for embedded MIPS environments with custom VM runtimes. This skill applies when building software that targets MIPS architecture with limited stdlib support, custom syscall interfaces, or JavaScript-based VM execution environments. Use when cross-compiling games, applications, or any C code for constrained MIPS targets.
Expert software architecture council with 6 advisors (Fowler, Beck, Uncle Bob, Newman, Hightower, Kim) for code design, architecture patterns, infrastructure, and development practices.
Wave-based parallel scheduling for DAG execution. Manages execution order, resource allocation, and parallelism constraints. Activate on 'schedule dag', 'execution waves', 'parallel scheduling', 'task queue', 'resource allocation'. NOT for building DAGs (use dag-graph-builder) or actual execution (use dag-parallel-executor).
