AI Agents
When not to use an agent
Agents are expensive, non-deterministic, and slow. Sometimes a form still wins.

The rule
If the process has ≤4 branches and the inputs are structured, build a form + a flow. It will be 10× cheaper to run, 100× more reliable, and no less useful to the user.
◆ Takeaway
Use an agent for shape-shifting requests. Use a flow for known ones.
