# Rule

Operation Rule defines, per Site, how a particular operation (for example `PowerControl` / `power_on` or `FirmwareControl` / `upgrade`) should be executed against a set of components: ordered execution stages, per-component-type concurrency, pre / main / post actions, timeouts, and retry policy. Rules are reusable templates owned by Flow; this tag exposes CRUD (`POST`, `GET`, `PATCH`, `DELETE`) over them.
