Infracost AI Agent Skills
Cloud cost intelligence for AI coding agents.
https://github.com/user-attachments/assets/16eef8f1-5bc1-4e5f-b5c4-c7594d883057
A collection of AI coding agent skills for Infracost users. These skills integrate Infracost workflows directly into your AI coding agent, providing cost estimation, optimization recommendations, and FinOps policy compliance for infrastructure as code.
Available Skills
| Skill | Description |
|---|---|
| iac-generation | Ensure cost optimization and FinOps/tagging policy compliance when writing infrastructure as code |
| scan | Analyze IaC projects to estimate cloud costs, identify savings opportunities, and flag FinOps policy violations |
| price-lookup | Look up cloud resource pricing by generating sample Terraform and running Infracost — no existing IaC required |
| install | Install or update the Infracost CLI from GitHub releases |
| uninstall | Uninstall the Infracost CLI |
| install-lsp | Install or update the Infracost Language Server |
Works with Terraform, Terragrunt, and CloudFormation. Supports AWS, GCP, and Azure.
Prerequisites
- A free Infracost account — sign up at infracost.io (takes under a minute; no credit card required).
Installation
[!IMPORTANT]
Make sure you've signed up for a free Infracost account before trying to use the AI skills (takes under a minute; no credit card required).
Claude Code
Install the plugin from the marketplace:
/plugin marketplace add infracost/agent-skills
/plugin install infracost@infracost
# Restart Claude
The skills will then be available as /infracost:<skill> slash commands.
Quick Start
After installing, try any of these prompts:
Scan for costs and policy violations:
Scan this Terraform project and tell me which resources are missing required tags.
Look up pricing without any existing code:
How much does an RDS PostgreSQL db.r5.xlarge cost in us-east-1?
Optimize to a budget:
Our budget is $2,000/month. Which resources are pushing us over, and what is the quickest
way to get under budget?
Generate compliant infrastructure:
Write Terraform for an RDS PostgreSQL instance for our payments service in us-east-1.
Required tags: team=payments, env=prod, cost-center=platform. Budget: $500/month.
How It Works
The Infracost skills connect to Infracost Cloud to retrieve real pricing data and your organization's policies. They read your local IaC files and combine that with live pricing and policy data to answer questions, surface violations, suggest fixes, and generate compliant new resources.
