# CoverageOptions

Options for a [cover](./cover) call.

Day/date scoping controls which days this coverage entry applies to. An entry without
`dayOfWeek` or `dates` applies every day in the scheduling period. `priority`
controls how hard the coverage floor is. `skillIds` is a hard filter, not a
preference. Use it only when the required minimum truly needs those skills throughout
the window. If a role or skill mix is preferred rather than required, model
that with rules such as [preferAssignment](./preferAssignment) instead of skill-filtered
coverage.
