W-Agent-FrameWork 是做什么的？
W-Agent is a production-grade Python agent development framework inspired by Spring architecture, providing enterprise-grade infrastructure for complex agent applications. It includes an IoC container (with three-level caching to resolve circular dependencies), declarative AOP aspects, retry/circuit breaker resilience patterns, and a dual sandbox security execution environment using Wasm and nsjail. It supports hot configuration reloading, distributed locking, OpenTelemetry observability, seamless FastAPI integration, and compatibility with the LangChain tool ecosystem. Without needing to build scaffolding from scratch, W-Agent empowers agent applications with industrial characteristics of high cohesion, easy testability, and operational maintainability.
