System Documentation
What problem does it solve?
Terraform changes can silently drive cloud costs up after deployment; this skill helps you estimate monthly spend and cost deltas from infrastructure code during PR review.
Core Features & Use Cases
- Infracost breakdown for Terraform: Generate a resource-by-resource monthly cost breakdown from Terraform code, including usage-based estimates (e.g., S3 storage and request volumes).
- PR cost diffs and guardrails: Produce before/after cost delta outputs suitable for CI comments, and fail builds when monthly cost increase exceeds a configured threshold.
- FinOps tagging and attribution: Apply and enforce tagging strategies (team/project/cost_center/environment) so costs can be attributed in reporting and policy checks.
Use case: When a data platform PR adds or modifies AWS resources (S3 buckets, RDS clusters, MSK, Athena, Lambda, etc.), you can estimate the monthly impact and block merges that exceed your budget.
Quick Start
Post a PR comment showing the monthly cost diff by running Infracost diff for the changed Terraform plan and comparing it to the base branch estimate.
