AWS re:Invent 2025 - Implementing Human-in-the-Loop Controls for Multi-Agent AI Systems (CNS428)
AWS Events. This lightning talk names the business moments where human control is needed: high-stakes decisions, irreversible actions, regulatory requirements, trust-building phases, ambiguous edge cases and graceful degradation. It also shows concrete implementation mechanisms such as MCP elicitations, Step Functions callback waits and approval nodes.
AI Expert note
The AWS service names and preview features can move. Use the decision criteria and pause/resume pattern, then implement the same controls with the stack you actually operate.
What you should get from this
See how approval gates can be implemented as explicit workflow checkpoints rather than informal manual review after something goes wrong.
