Event Sourcing and CQRS patterns. Event stores, projections, snapshots, command handlers, query models, and eventual consistency. Covers EventStoreDB, Axon Framework, and custom implementations. USE WHEN: user mentions "event sourcing", "CQRS", "event store", "projection", "command handler", "read model", "write model", "EventStoreDB", "Axon" DO NOT USE FOR: simple event-driven architecture - use `event-driven`; message brokers - use messaging skills; DDD basics - use `ddd`
Opinionated guide to software design principles and architectural patterns. Use when reviewing code design, planning feature architecture, asking "is this the right design?", "how should I structure this?", or requesting design philosophy guidance. Triggers on questions about SOLID, DRY, KISS, YAGNI, Clean Architecture, DDD, hexagonal architecture, composition vs inheritance, coupling, cohesion, or any software design trade-off discussion.
Build unified cross-chain USDC balance management with Circle Unified Balance Kit SDK via App Kit (`@circle-fin/app-kit`) or standalone (`@circle-fin/unified-balance-kit`). Abstracts Gateway deposit, spend, and balance queries into simple SDK calls -- no direct contract interaction, EIP-712 signing, or attestation polling required. App Kit is recommended for extensibility across swap, bridge, send, and unified balance. Standalone Unified Balance Kit provides the same API surface in a lighter package. Neither requires a kit key for unified balance operations. Supports EVM chains and Solana via adapter packages. Use when: depositing USDC into a unified balance, spending from a unified balance to any supported chain, checking unified balance across chains, setting up Unified Balance Kit adapters (Viem, Solana, Circle Wallets), managing delegates for account separation, or building chain-abstracted USDC payment flows. Triggers on: unified balance, Unified Balance Kit, UnifiedBalanceKit, @circle-fin/unified-balance-kit, deposit USDC unified, spend unified balance, getBalances, cross-chain USDC SDK, chain abstraction SDK, adapter-viem, adapter-solana, depositFor, addDelegate, unified USDC.
Domain-Driven Design tactical patterns for complex business domains. Use when modeling entities, value objects, domain services, repositories, or establishing bounded contexts.
Complete Microsoft .NET Microservices Architecture guide (v7.0) - 350 pages of comprehensive reference material
Complete guide for enterprise architecture patterns including domain-driven design, event sourcing, CQRS, saga patterns, API gateway, service mesh, and scalability
Provides implementation patterns for Clean Architecture, Hexagonal Architecture (Ports & Adapters), and Domain-Driven Design in Java 21+ Spring Boot 3.5+ applications. Use when structuring layered architectures, separating domain logic from frameworks, implementing ports and adapters, creating entities/value objects/aggregates, or refactoring monolithic codebases for testability and maintainability.
This skill should be used when a user wants to create, draft, or plan a GitHub Epic issue — for example "write an epic", "I want to define a new initiative", "scope out this strategic project", "turn this idea into an epic", "plan work that spans multiple features", or "start from a bounded context". Also use when the user asks to define domain outcomes, capture a large initiative before breaking it into features, or describe work in terms of business goals rather than technical tasks.
Software architecture patterns and best practices
處理跨 Bounded Context 的依賴關係。當需求涉及多個限界上下文（如權限管理、付款、通知）時觸發，設計 Anti-Corruption Layer 和 Context Mapping。
This skill should be used when the user asks to "add a database table", "create a new context", "query the database", "add a field to a schema", "validate form input", "fix N+1 queries", "preload this association", "separate these concerns", or mentions Repo, changesets, migrations, Ecto.Multi, has_many, belongs_to, transactions, query composition, or how contexts should talk to each other.
