Implement Server-Sent Events for real-time server-to-client updates. Use for live feeds, notifications, and streaming data.
Implement graceful server shutdown to handle in-flight requests before stopping. Use for zero-downtime deployments and proper resource cleanup.
Implement request logging, tracing, and observability. Use for debugging, monitoring, and production observability.
Expert guidance for building production-ready FastAPI applications with modular architecture where each business domain is an independent module with own routes, models, schemas, services, cache, and migrations. Uses UV + pyproject.toml for modern Python dependency management, project name subdirectory for clean workspace organization, structlog (JSON+colored logging), pydantic-settings configuration, auto-discovery module loader, async SQLAlchemy with PostgreSQL, per-module Alembic migrations, Redis/memory cache with module-specific namespaces, central httpx client, OpenTelemetry/Prometheus observability, conversation ID tracking (X-Conversation-ID header+cookie), conditional Keycloak/app-based RBAC authentication, DDD/clean code principles, and automation scripts for rapid module development. Use when user requests FastAPI project setup, modular architecture, independent module development, microservice architecture, async database operations, caching strategies, logging patterns, configuration management, authentication systems, observability implementation, or enterprise Python web services. Supports max 3-4 route nesting depth, cache invalidation patterns, inter-module communication via service layer, and comprehensive error handling workflows.
Build and deploy a paid API that other agents can pay to use via x402. Use when you or the user want to monetize an API, make money, earn money, offer a service, sell a service to other agents, charge for endpoints, create a paid endpoint, or set up a paid service. Covers "make money by offering an endpoint", "sell a service", "monetize your data", "create a paid API".
Distributed locking patterns with Redis and PostgreSQL for coordination across instances. Use when implementing exclusive access, preventing race conditions, or coordinating distributed resources.
Converts JSON data snippets into Python Pydantic data models.
Microservice Infrastructure Guide, covering core infrastructure of microservice architecture such as conditional configuration, event-driven architecture, inter-service communication, internationalization and logging. It is used when users implement inter-service calls, configure multi-environments, implement asynchronous communication, handle internationalization or standardize log output.
General .NET development workflow patterns. Use when implementing features, fixing bugs, or refactoring code.
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。
專責處理 CBF (Commanded Behavior Frame) 類型的需求。讀取規格目錄結構，生成/審查 Command Side 設計與實作。支援 Java、TypeScript、Go 多語言。
Package development and extraction of reusable code. Use when working with package development, code reusability, or when user mentions packages, composer packages, extract package, reusable code, package development.
