Backend engineer focused on Agent Harness, Tool Use, MCP, Evals, and AI infrastructure.
Zexu Jin writes agent skills centered on the LangChain and LangGraph ecosystem, covering human-in-the-loop approval and structured output, state persistence and memory, tracing and trace querying in LangSmith, and building evaluation datasets from agent traces. The catalog also reaches beyond agent tooling, with skills for root-cause analysis, decision trade-off reasoning, daily planning routines, and JSON Canvas file editing. Taken together, the skills show a focus on making agent systems observable, testable, and controllable.
