application-metrics

Quick Review

This skill provides a well-structured guide for instrumenting applications with metrics across common components (APIs, databases, queues, caching, locks). The description clearly indicates when to use it, and the content covers the five key metric types with naming conventions, component-specific checklists, and anti-patterns. Structure is clean with tables and organized sections. Task knowledge is solid for implementation - a CLI agent could follow the checklists and patterns to add instrumentation. Novelty is moderate: while the skill consolidates best practices that would otherwise require research and multiple tokens, the patterns themselves are relatively standard in the observability domain. The skill would save a CLI agent effort in researching metrics naming and coverage, but doesn't involve highly complex or proprietary logic.
