Minimal Rule Skeleton

rule_type = "gauge_threshold"
metric_name = "my_metric_name"
display_name = "my_metric_name"
description = "What this metric means"

[thresholds]
low = 100
high = 1000
higher_is_worse = true

[messages]
green = "{value:.0f} healthy"
yellow = "{value:.0f} elevated"
red = "{value:.0f} critical"
