The cost curve starts after launch.

The creator quietly becomes product support.

Use a short trial with failure and support logs.

A product needs an owner even if AI wrote its code.

The first graph looks amazing: a useful internal tool appears in a day. The second graph is the one leaders miss. Each exception asks someone to stop their real work, reconstruct the agent's choices and supervise another repair cycle.

Imagine a sales operator builds an intake portal with an agent. It works for the launch path. A permission issue, old record and export mismatch arrive later. The operator spends afternoons re-prompting and retesting instead of serving accounts. The software expense looks small because that time is booked elsewhere.

For a trial, log the agent spend, owner intervention time, missed core-work time, incidents and users who now depend on it. Compare with a maintained tool that performs the same job. The decision does not need a perfect forecast; it needs the hidden costs on the same page.

Approve an internal build only with a named owner, maintenance budget, acceptance tests and a retire-or-replace trigger. Otherwise, buy the small maintained tool and keep people on their actual job. Do this because the first working screen does not finance the next year of exceptions.
