Facio's Web Research Stack: How web_search and web_fetch Turn AI Agents Into Live Research Engines

AI agents with training data cutoffs are answering questions about a world that has moved on. Facio's web_search and web_fetch tools give agents direct access to the live web — search for sources, fetch the actual content, extract what's relevant, and reason over it. Combined with the search-reason loop, agents can run production-grade research workflows that match what humans do with browser tabs.

Here's why notebook-aware editing matters for data science agents.
