Your Coding Agent Is 6 Months Out of Date — Jakub Hojsan, Exa

This post contributes to agent harness engineering by detailing Exa's solution to the knowledge-cutoff gap in coding agents. It explains why simply adding a web search tool is insufficient and proposes giving agents explicit rules for when to search. The talk also introduces query-dependent highlights, a technique that reduces a large page to a few hundred characters with no added latency, and previews Exa Agent, demonstrating its capabilities in finding conference speakers. The core technical contribution is the development of a search system specifically for coding and code-review agents that overcomes model knowledge limitations.
