AI / Agentic AI Interview Questions
What is a Human-in-the-Loop checkpoint?
A Human-in-the-Loop checkpoint is a deliberate pause in an otherwise autonomous agent workflow where a human must review or approve an action before the agent proceeds.
- Commonly inserted before high-stakes or irreversible actions, like sending an email or executing a financial transaction
- Lets an agent operate autonomously for most of a task while still keeping a person accountable for the riskiest steps
- Can be implemented explicitly as a graph node in frameworks like LangGraph that require approval before continuing
This is a common practical compromise between full autonomy and full manual control, letting an agent handle the routine work while a human retains the final say on consequential actions.
