metrics-collector

What problem does it solve?

This Skill prevents accidental corruption of Prometheus metrics by enforcing strict rules on metric names, labels, cardinality, and emission patterns when modifying the metrics collector.

Core Features & Use Cases

• Metric Name Preservation: Ensures existing Prometheus metric names are not removed or renamed.
• Label Stability: Guarantees that labels on existing metrics remain unchanged and new required labels are not added.
• Cardinality Control: Prevents the introduction of unbounded cardinality labels, which can overload monitoring systems.
• Use Case: When a developer needs to add a new metric to track API gateway request latency, they would use this skill to ensure the new metric adheres to all established naming conventions, label usage, and cardinality limits.
