Practical fit
Follow-a-goal workflows fit migrations, refactors, and repair tasks where progress can be tested repeatedly. The value is not continuous activity; it is the ability to keep returning to one measurable condition while preserving the constraints around it.
The approach works poorly when success depends on taste, hidden stakeholder expectations, or a requirement that has not been written down. Those tasks need a human decision before an agent can loop responsibly.
How to evaluate it
Example decision
For a library migration, define success as the new API compiling, the affected tests passing, and the deprecated imports reaching zero. Stop after a repeated blocker and report the remaining call sites instead of broadening into unrelated cleanup.
