Building a One-Liner Research Agent
Research tasks consume hours of expert time: market analysts manually gathering competitive intelligence, legal teams tracking regulatory changes, engineers investigating bug reports across documentation. The core challenge isn't finding information but knowing what to search for next based on what you just discovered.
The Haijun Agent SDK makes it possible to build agents that autonomously explore external systems without a predefined workflow. Unlike traditional workflow automations that follow fixed steps, research agents adapt their strategy based on what they find--following promising leads, synthesizing conflicting sources, and knowing when they have enough information to answer the question.
This foundation applies to any task where the information needed isn't available upfront: competitive analysis, technical troubleshooting, investment research, or literature reviews.
