Find the right Agents stack

AI agents are the most over-promised category in this index, and also the one with the highest ceiling. The difference between a useful agent and an expensive science project is governance: can it take real actions across your systems, can a human see and stop what it's doing, and does it fail safe instead of confidently doing the wrong thing at scale? Discount any vendor that demos a flashy autonomous loop but can't answer 'what happens when it's wrong on transaction 4,000.' The agents worth deploying have tight permission scoping, reliable integrations, an audit trail, and a clear human-escalation path. Start with one bounded, measurable workflow — not 'replace a team' — and expand only once it's earned trust on real volume.
