# yaml/parse

You will only ever see this check reporting problems if a file containing
Prometheus rules to check doesn't parse as valid [YAML](https://yaml.org/),
meaning that pint is unable to read any rules from that file.

This includes basic YAML parser checks but will also fail if a rule
block contains duplicated keys, example:

```yaml
- record: foo
  expr: sum(my_metric)
  expr: sum(my_metric) without(instance)
```
