Excellent skill for LangChain SDK migration. The description clearly identifies when to use this skill (version upgrades, breaking changes, legacy pattern migrations). Task knowledge is comprehensive with concrete code examples for all major migration patterns (imports, chains→LCEL, agents, memory), version-specific breaking changes, and a complete upgrade workflow. Structure is logical with clear steps, a migration checklist, and error handling table. Novelty is solid—while a skilled developer could perform these migrations manually, the skill consolidates scattered documentation, provides ready-to-use migration scripts, and handles the complexity of LangChain's frequent breaking changes across 0.1→0.2→0.3. This saves significant time researching migration paths and reduces token usage compared to asking an LLM to figure out all breaking changes and patterns from scratch.
