### Overview

Retrieve a single tag rule by ID. Optionally include the rule's current compliance
score via the `include=score` query parameter. Rules belonging to other organizations
cannot be retrieved.

This endpoint requires any of the following permissions:

- `telemetry_rules_read`
- `metrics_read`
