Aws/cost Report

Format AWS cost estimates into readable reports with breakdowns and recommendations.

Features

• Formatted markdown tables for EC2, RDS, and spec-based estimates
• Cost breakdowns by tag (owner, project)
• Actionable recommendations for cost optimization
• JSON output for programmatic analysis

Usage

The report runs automatically after @webframp/aws/cost-estimate methods. It can also be run standalone:

# Run after method execution (automatic)
swamp model method run cost-est estimate_from_spec --input-file spec.json

# Run standalone on existing model
swamp model report cost-est --json

Report Output

• Resource tables with per-item costs
• Tag-based cost allocation (by owner, project)
• Recommendations for:
  • Right-sizing expensive resources
  • Windows to Linux migration opportunities
  • Multi-AZ considerations for RDS
  • Tagging gaps

Labels

Filter reports using labels:

swamp model method run <model> <method> --report-label cost
