Start with the process
A workflow describes known steps: what starts the work, what data is required, who approves, and what happens next. Those steps should remain visible even when AI assists with part of the task.
Use an agent for bounded judgment
An agent can help interpret a request, gather relevant context, or draft a recommendation. Give it a narrow job, permitted tools, and an expected output that a person or rule can evaluate.
Put them together deliberately
The workflow can call an agent at a defined point and then route its output through a policy check or approval. This makes the end-to-end process understandable while preserving useful flexibility.
