In this fourth post in my series, Observability: Why Did Your Agent Do That?, I look at the AI Agent observability problem. (You can find the three earlier posts here: Part 1: Autonomy with Brakes: Why Refusal Comes First , Part 2: Disobedient or Just Probabilistic , and Part 3: The Importance of the Context Layer.) At Real Story Group, we’ve researched more than twenty Agent AI tools and have advised several enterprise clients on different Agent AI aspects.
