# Cost Observability and Monitoring ## Overview Cost Observability is the practice of extending traditional system observability (logs, metrics, traces) to include **Financial** data. It allows engineering teams to answer not just "Is the system healthy?" but "Is the system cost-effective?". **Core Principle**: "Total spend is a vanity metric; cost per unit of work is a performance metric." --- ## 1. Key Cost Metrics to Track The goal is to move from **Macro** visibility (the bill) to **Micro** visibility (the request). | Metric | Level | Purpose | | :--- | :--- | :--- | | **Total Monthly Spend** | Executive | General budget health. | | **Cost per Service** | Engineering | Identify inefficient microservices. | | **Cost per Customer (Unit Cost)**| Product | Calculate per-account profitability. | | **Cost per Request** | Engineering | Measure efficiency of application code. | | **COGS (Cost of Goods Sold)** | Financial | The base cost to deliver the service. | --- ## 2. Cost Attribution and Tagging Strategy Attribution is impossible without consistent metadata. ### The Standard Tagging Schema Every resource should have the following "FinOps Tags": 1. **`Environment`**: (e.g., `prod`,

What does the Cost Observability and Monitoring skill do?
Techniques for gaining visibility into cloud spending, attributing costs to business units, and detecting financial anomalies.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill cost-observability-amnadtaowsoam-cerebratechai-claude --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
