SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Managing AWS spending, monitoring infrastructure health, and auditing account activity requires juggling multiple consoles and APIs. This Skill centralizes cost estimation, cost analysis, CloudWatch monitoring, and CloudTrail auditing into guided workflows backed by integrated MCP servers. ## Core Features & Use Cases - Cost Estimation & Optimization: Estimate pre-deployment costs with the AWS Pricing MCP, analyze historical spending with Cost Explorer MCP, and identify right-sizing and unused-resource savings. - Monitoring & Alerting: Query CloudWatch metrics and logs, and apply ready-made alarm configurations for Lambda, EC2, RDS, DynamoDB, ECS, SQS, API Gateway, and ALB. - Audit & Security: Investigate CloudTrail API activity, troubleshoot incidents, and run Well-Architected security posture assessments. - Use Case: Ask why your AWS bill spiked last month—the Skill uses Cost Explorer to find the responsible service, CloudWatch to check usage metrics, and CloudTrail to trace recent resource creation. ## Quick Start Ask the assistant to estimate the monthly cost of your planned architecture or to analyze last month's AWS spending by service.

Frequently Asked Questions about aws-cost-operations

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I estimate AWS costs before deploying resources?▼

Use the AWS Pricing MCP server to query pricing for each planned resource, compare costs across regions, and calculate expected monthly totals based on projected usage. This workflow helps evaluate alternative service options before committing to a deployment.

How do I find out why my AWS bill increased?▼

Use the Cost Explorer MCP to break down spending by service, region, and tag, then identify anomalies exceeding normal trends. Cross-reference CloudWatch usage metrics and CloudTrail resource creation events to pinpoint the root cause.

What CloudWatch alarms should I set for Lambda functions?▼

The reference recommends alarms for error count, duration approaching 80% of timeout, throttles above zero, and concurrent executions nearing reserved limits. CDK code examples for each alarm are included in the cloudwatch-alarms reference.

Which MCP servers are bundled with this skill?▼

Three servers are bundled: AWS Pricing for cost estimation, Cost Explorer for spending analysis, and CloudWatch for metrics, alarms, and logs. Billing, CloudTrail, Application Signals, and Well-Architected assessment servers are available separately via the aws-mcp-setup skill.

Does this skill work without the AWS MCP servers configured?▼

No, the MCP tools must be available for the core workflows. The aws-mcp-setup dependency is auto-loaded, and if MCP tools are unavailable the skill guides you through that setup flow first.

How do I audit who deleted an AWS resource?▼

Query CloudTrail for the relevant API event, such as DeleteBucket for S3, filtered by time range and user identity. The skill provides audit query patterns for IAM changes, failed logins, and privileged actions.
