[Pragmatic DDD Architecture] Guide for creating DDD Value Objects (VOs). Use when defining a new Value Object in a domain layer. Covers immutability patterns, private constructors, random/from builders, Railway-oriented error handling via neverthrow Result, TypeScript branded error types, and co-locating errors within the VO file.
[Pragmatic DDD Architecture] Guide for creating DDD Entities and Aggregates. Use when defining new domain entities with business rules, private state, and getters. Covers entity instantiation via objects, integration with Value Objects, and the rule against using setters.
Query BingX standard contract positions, historical orders, and account balance. Use when the user asks about BingX standard contract positions, standard futures order history, or standard contract balance.
Jito bundle submission for MEV protection on Solana — bundle building, tip strategies, block engine endpoints, and landing rate optimization
Drupal cache contexts implementation guide. Use when asked about request-based cache variations, user.roles vs user context, URL contexts, language contexts, custom cache contexts, or cache context hierarchy. Helps prevent cache explosion from overly broad contexts.
Comprehensive map and workflows for the API domain. Triggers when users ask to 'design an API', 'secure the APIs', 'update endpoints', 'view the API ecosystem', or want to see all available API orchestration skills.
Implements CQRS with event sourcing on the iii engine. Use when building command/query separation, event-sourced systems, or fan-out architectures where commands publish domain events and multiple read model projections subscribe independently.
NCU-driven iterative optimization workflow for CUDA/CUTLASS/Triton/CuTe DSL kernels. MANDATORY: every optimization MUST start with NCU profiling, followed by multi-dimensional analysis, then targeted code modification, then re-profiling to verify. Supports roofline, memory hierarchy, warp stalls, instruction mix, occupancy, divergence analysis. Provides implementation-specific code modifications: Native CUDA (launch config, memory patterns, async copy, Tensor Core), CUTLASS (ThreadblockShape, stages, epilogue, schedule policy, alignment), Triton (autotune params, compiler hints, tl.* API patterns), CuTe DSL (threads_per_cta, elems_per_thread, tiled_copy, copy atom, shared memory, warp/cta reduce). Use when optimizing any CUDA kernel performance.
Steedos Server REST API reference (v6). Covers data CRUD endpoints (/api/v6/data), object metadata endpoints (/api/v6/objects), function execution endpoints (/api/v6/functions), file upload, health checks, and public settings. Includes query parameters (fields, filters, sort, skip, top), filter operators, authentication via cookies/bearer token, response formats, and Swagger/OpenAPI documentation.
Declarative HTTP client for microservices communication with Spring Cloud OpenFeign. Covers @FeignClient, error handling, interceptors, and circuit breaker integration. USE WHEN: user mentions "feign", "openfeign", "@FeignClient", "declarative HTTP client", "service-to-service communication", "microservices client" DO NOT USE FOR: external APIs - consider WebClient or RestClient, simple HTTP calls - use RestClient
Generates optimized read queries using Dapper. Includes multi-mapping for joins, pagination, dynamic filtering, CTEs, and best practices for high-performance data access.
Guide first-time Enable Banking API setup and sample flows: Control Panel signup, sandbox application registration, browser-generated private key download, RS256 JWT creation, Authorization header setup, listing ASPSPs, starting AIS authorization, exchanging callback code for a session, fetching balances and transactions, creating a SEPA payment, redirecting the PSU, and checking payment status. Use when Codex needs to onboard a developer quickly or scaffold a minimal working Enable Banking sandbox integration.
