Create a 3 tier web app on AWS using ECS & Postgres. It needs to be compliant with all of my organization's finops and tagging policies, and cost less than $100/mo

Policy Compliance

All 14 policies pass. Key decisions made:

- Graviton (ARM64) on ECS task definitions & RDS (db.t4g.micro) — ~20% cheaper than x86

- gp3 storage on RDS — 20% cheaper than gp2

- Single-AZ RDS — for Dev, saves ~50% vs multi-AZ

- HTTP → HTTPS redirect on ALB (ELB.1 compliance)

- Secrets Manager for DB password — not env vars

- RDS encryption at rest (storage_encrypted = true)

- copy_tags_to_snapshot = true on RDS

- CloudWatch log exports enabled on RDS

- propagate_tags = "TASK_DEFINITION" on ECS services

The Problem

Why cost visibility matters at the source

Discovering cost overruns after deployment means expensive rework, delayed releases, and uncomfortable conversations with finance. The earlier you catch cost issues, the cheaper they are to fix.

Caught late, cost more

A misconfigured instance spotted at code review costs minutes to fix. The same issue found in production costs days of incident response and thousands in unexpected spend.

Tagging debt compounds

Untagged resources are invisible to FinOps teams. Every untagged resource deployed today becomes a compliance gap, a cost attribution blind spot, and a manual cleanup task next quarter.

Compliance from the start

When cost and compliance awareness is built into your IaC authoring workflow, engineers ship compliant infrastructure on the first try — eliminating the FinOps review bottleneck entirely.

Get Started

Up and running in 2 steps

Infracost AI is a native Claude Code skill. No new tools or CLIs — just two commands in Claude Code.

Step 1 — Install the Infracost Marketplace

Open Claude Code and run the following plugin command:

/plugin marketplace add infracost/agent-skills

Step 2 — Install the Infracost Skills

Once the marketplace is installed, install the Infracost Skill (you'll need to restart Claude Code for the changes to take effect). Claude will guide you through connecting your Infracost account — your API key is configured automatically.

/plugin install infracost@infracost

Use Cases

See it in action

Infracost AI understands your infrastructure.
Here's what that unlocks.

Spot every tagging gap across your infrastructure

You can't fix what you can't see.

Untagged or incorrectly tagged resources create cost attribution gaps, compliance violations, and blind spots in your FinOps reporting. Infracost AI scans your entire IaC codebase and surfaces every resource missing required tags — before they ever get deployed.

Identifies all resources missing required tag keys
Highlights which tags are wrong, missing, or inconsistently applied
Shows the cost and compliance impact of each gap
Works across Terraform, Terragrunt, and OpenTofu

Fix tagging violations 100× faster

From audit to compliant in seconds, not sprints.

When Infracost AI finds a tagging issue, it doesn't just report it — it fixes it. Tell Claude what your required tag standards are, and it applies them across every affected resource in one shot. What used to take days of manual Terraform editing now takes a single command.

Auto-generates tag fixes for all flagged resources
Applies your organization's tag standards (team, env, cost-center, etc.)
Shows a diff before applying any changes
Handles complex modules and nested resources

Adjust resources to fit within budget

Ship more within budget, not less.

Got a cost threshold to hit? Tell Infracost AI your budget and it'll analyze your current resource configuration, identify the highest-impact changes, and suggest rightsizing options — while explaining the performance trade-offs of each change.

Analyzes current monthly cost against your stated budget
Identifies top cost drivers and rightsizing opportunities
Suggests specific instance type or tier changes
Estimates new monthly cost after each change

Generate new infrastructure that's compliant from the start

Zero surprises at review time.

Ask Infracost AI to write Infrastructure as Code (IaC) for a new service, and it generates code that's already within your budget, tagged correctly, and compliant with your org's standards — on the first attempt. No back-and-forth with your FinOps team.

Generates Infrastructure as Code with required tags pre-applied
Selects instance types that fit within your cost constraints
Validates against your org's policy rules before output
Dramatically reduces FinOps review cycles
