Introducing LangSmith Fetch: Debug agents from your terminal

LangSmith Fetch is a new command-line interface (CLI) tool that brings LangSmith tracing capabilities directly into a developer's terminal. It is designed to solve the friction of context-switching to a web UI when debugging AI agents. With a single command, developers can pull trace or thread data, making it easier to inspect what happened during an agent's execution. The tool also supports bulk exporting for creating evaluation datasets and can pipe trace information directly to AI coding assistants to help analyze failures and suggest improvements.
