Agent Harnesses

View as MarkdownOpen in Claude

A coding agent’s training data stops at a cutoff, so current library docs, error threads, and release notes are not in the model. Web search finds those pages, fetch reads one when the agent already has the URL, and research covers a question that needs several sources. Setup for the live APIs is in the MCP Server guide.
