Agents are not useful because they are agents.
They are useful when they own a narrow job inside a real workflow. Without boundaries, an agent becomes an expensive way to create uncertainty.
01
Give it a real job
A good agent starts with a narrow outcome. Vague goals create vague behavior.
Specific input
Clear output
Allowed tools
Escalation rule
02
Choose the simplest system
Many workflows do not need an agent. A rule, form, automation, or draft assistant may be safer and cheaper.
Use rules for stable logic
Use drafts for judgment-heavy work
Use agents for multi-step tasks
Use humans for final decisions
03
Supervise the work

Activity log
Human approval
Tool permissions
Quality review
Questions to ask before the first sprint
What job would the agent own?
What tools can it access safely?
When should it stop and ask a person?
