+description: |
+  This skill enables Claude to analyze and optimize cloud costs. It identifies areas for potential savings, generates cost reports, and suggests configuration changes to reduce expenses. Use this skill when the user asks to "optimize cloud costs", "reduce cloud spending", "generate a cost report", or similar requests related to cloud resource expenses. It is especially useful when the user provides details about their cloud environment (e.g., AWS, Azure, GCP). The skill leverages best practices for cost optimization and provides production-ready configurations.

+version: 1.0.0
+---
+
+## Overview
+
+This skill empowers Claude to be a FinOps expert, helping users identify and implement strategies to minimize their cloud expenditures. By analyzing current resource utilization and suggesting optimized configurations, it ensures efficient cloud spending.
+
+## How It Works
+
+1. **Analyzing Cost Data**: Claude analyzes the user's request to identify the scope and cloud provider (if specified).
+2. **Generating Optimization Recommendations**: Claude formulates specific recommendations to reduce costs, such as rightsizing instances, identifying unused resources, or leveraging reserved instances.
+3. **Creating Cost Report**: Claude generates a detailed cost report summarizing current spending and potential savings.
+
+## When to Use This Skill
+
+This skill activates when you need to:
+- Reduce your AWS, Azure, or GCP cloud spending.
+- Generate a report detailing current cloud costs.
+- Identify underutilized or unused cloud resources.
+
+## Examples
+
+### Example 1: Reducing AWS EC2 Costs
+
+User request: "Optimize my AWS EC2 costs. I'm running several t3.medium instances."
+
+The skill will:
+1. Analyze the usage patterns of the t3.medium instances.
+2. Suggest rightsizing to t3.small or using reserved instances if utilization is consistently high.
+3. Generate a cost report showing potential savings from the recommended changes.
+
+### Example 2: Identifying Idle Azure Resources
+
+User request: "Generate a report of idle resources in my Azure subscription."
+
+The skill will:
+1. Identify any virtual machines, storage accounts, or other resources that have been idle for a specified period.
+2. Recommend terminating or deallocating the idle resources.
+3. Provide a cost report detailing the savings achieved by removing the idle resources.
+
+## Best Practices
+
+- **Resource Utilization**: Regularly review resource utilization metrics to identify opportunities for rightsizing.
+- **Reserved Instances**: Leverage reserved instances or committed use discounts for consistently used resources.
+- **Cost Monitoring**: Implement continuous cost monitoring and alerting to track spending trends and identify anomalies.
+
+## Integration
+
+This skill can be used in conjunction with other DevOps plugins to automate the implementation of cost optimization recommendations. For example, it can integrate with infrastructure-as-code tools to automatically resize instances or terminate unused resources.

+# Cloud Cost Report Template
+# This CSV file provides a template for generating cost reports.
+# Each row represents a cost item.
+#
+# Columns:
+#   - Date: The date of the cost (YYYY-MM-DD).
+#   - Account: The account or project associated with the cost.
+#   - Service: The cloud service used (e.g., EC2, S3, RDS).
+#   - Region: The AWS region (e.g., us-east-1, eu-west-1). Use 'Global' if applicable.
+#   - Item: A descriptive name for the cost item.
+#   - Cost: The cost in USD.
+#   - Unit: The unit of measurement for the item (e.g., hours, GB, requests).  Leave blank if not applicable.
+#   - Quantity: The quantity consumed.  Leave blank if not applicable.
+#   - Notes: Any additional notes or descriptions.
+#
+# Example usage:
+# 2023-10-26,ProjectA,EC2,us-east-1,Instance m5.large,1.20,hours,10,Compute costs for web server
