langchain-sdk-patterns

Quick Review

Strong skill providing production-ready LangChain patterns with executable code examples. The description clearly indicates when to use the skill (implementing integrations, refactoring, establishing standards) and includes relevant trigger phrases. Task knowledge is excellent with 5 concrete patterns covering type-safety, error handling, async processing, streaming, and caching—all critical for production LangChain apps. Structure is good with clear pattern separation and error handling section, though a patterns index could improve navigation. Novelty is moderate: while these patterns save tokens vs. researching docs, an experienced LangChain developer might know them, and a CLI agent could construct similar solutions with documentation access, though less efficiently. The skill meaningfully consolidates best practices that would otherwise require browsing multiple doc pages and trial-and-error.
