# Sequence checked units

Treat the request text that activated this skill as the multi-step work to sequence.

Apply [sequence verifiable units](../pkstack-principles/references/catalog.md#sequence-verifiable-units).
Choose the smallest unit that ends in a real check, verify it before building on it, and order the
series so baseline precedes treatment and regression precedes fix. Return the unit list, check for
each unit, and first unresolved boundary.
