CQRS Implementation guides separating read and write models for scalable architectures and event-sourced systems. Use it when you need to scale reads and writes independently, optimize query performance, or implement high-performance reporting.

DeFi Protocol Templates provides production-ready templates for staking, AMMs, governance, and flash loans. Use when building decentralized finance applications or smart contract protocols.

Event Store Design provides patterns and guidance for designing and implementing event stores in event-sourced systems. Use it when choosing event store technologies, implementing persistence, or optimizing event storage and retrieval.

FastAPI Templates scaffolds production-ready FastAPI projects with async patterns, dependency injection, middleware, and testing setup. Use it when starting new FastAPI applications or building high-performance async APIs.

Microservices Patterns helps design microservices architectures with service boundaries, event-driven communication, and resilience patterns. Use it when building distributed systems, decomposing monoliths, or implementing microservices.

Multi-Reviewer Patterns coordinates parallel code reviews across multiple quality dimensions, deduplicating findings, calibrating severity, and producing consolidated reports. Use it when organizing multi-reviewer code reviews or consolidating review results.

NFT Standards implements ERC-721 and ERC-1155 NFT contracts with proper metadata handling, minting strategies, and marketplace integration. Use when creating NFT collections, building marketplaces, or implementing digital asset systems.

Parallel Debugging debugs complex issues using the Analysis of Competing Hypotheses methodology with parallel agent investigation, evidence collection, and root cause arbitration. Use it when bugs have multiple potential causes or need systematic root cause analysis.

Parallel Feature Development coordinates parallel feature work by defining file ownership boundaries, interface contracts, and integration patterns so multiple agents can implement different parts of a system without merge conflicts.

Projection Patterns builds read models and projections from event streams. Use it for implementing CQRS read sides, building materialized views, or optimizing query performance in event-sourced systems.

Saga Orchestration implements saga patterns for distributed transactions and cross-aggregate workflows. Use it when coordinating microservices without two-phase commit, designing compensating actions for multi-service workflows, or debugging stuck saga states.

Screen Reader Testing helps validate web applications with screen readers including VoiceOver, NVDA, and JAWS. Use when checking accessibility, debugging assistive technology issues, or ensuring ARIA support.
