cost-optimization gives Claude a four-step framework: visibility, right-sizing, pricing models and architecture changes. It then lists tactics per provider, such as reserved instances and savings plans on AWS, hybrid benefit on Azure, committed use discounts on GCP and flexible shapes on OCI. It adds Terraform examples for S3 lifecycle rules, budgets and autoscaling, a tagging strategy, and a 15-item checklist.

It triggers when you ask about reducing cloud expenses or analyzing spend. The folder holds 2 Markdown files and no scripts. The discount percentages in the SKILL.md are static text, so check current pricing before you commit to a purchase.

Good for

  • Engineers and FinOps owners asked to reduce cloud spend
  • Teams running on AWS, Azure, GCP or OCI
  • Teams writing a tagging standard for cost allocation

Install cost-optimization

Claude Code

  1. 1

    Copy this prompt.

    Install the cost-optimization skill in Claude Code. Run this command:

/plugin marketplace add wshobson/agents
/plugin install cloud-infrastructure@claude-code-workflows

Then check that it loaded and tell me how to use it.
  2. 2

    Paste it into Claude Code. It shows the change and asks before running it.

Pick one route. The cloud-infrastructure plugin adds 7 more cloud skills and 7 agents. The skills-only route installs just this skill, without the plugin's agents or commands (README).

Built from the package data we hold. Not yet tested by us.

What's in the skill

When it loads

Optimize cloud costs across AWS, Azure, GCP, and OCI through resource rightsizing, tagging strategies, reserved instances, and spending analysis. Use when reducing cloud expenses, analyzing infrastructure costs, or implementing cost governance policies.

What it includes

  • Four steps: visibility, right-sizing, pricing models, architecture.

    The core outline of the skill.

    Cost optimization framework

  • Reserved instances, savings plans, spot instances and S3 lifecycle rules.

    Includes a Terraform S3 lifecycle example that expires objects after 365 days.

    Delete · AWS tactics

  • Reserved VM instances, Hybrid Benefit and Advisor recommendations.

    Azure tactics

  • Committed use discounts, sustained use discounts and preemptible VMs.

    GCP tactics

  • Flexible shapes, commitments and budgets, preemptible capacity.

    OCI tactics

  • Common tags such as Environment, Project, CostCenter and Owner, in Terraform.

    Detail in references/tagging-standards.md.

    Write · Tagging strategy

  • A Terraform AWS budget with an 80 percent alert, plus anomaly detection per provider.

    The example sends alerts to an email address you set.

    Write · Cost monitoring

  • Serverless first, right-sized databases, multi-tier storage and autoscaling.

    Four patterns with examples.

    Architecture patterns

  • 15 items, from tags and unused resources to weekly reviews.

    Cost optimization checklist

  • Names native tools per cloud and CloudHealth, Cloudability and Kubecost for multi-cloud.

Permissions

Medium risk

The skill's examples include lifecycle rules that expire objects and a checklist item to delete unused EBS volumes, IPs and snapshots. Review every Terraform plan and every deletion before you apply it.

What it can do

  • Read your data
  • Create and change things
  • Delete things
  • Read-only mode

Watch out for

  • Examples can delete stored data

    The S3 example moves objects to cheaper storage and expires them after 365 days. Applying it unchanged to a bucket you care about removes data. github.com

  • The checklist says to delete unused resources

    It lists EBS volumes, elastic IPs and snapshots. Confirm each is unused before any deletion. github.com

  • Budget alerts need a real email address

    The AWS budget example sends alerts to an address you set. Replace the placeholder before applying. github.com

Questions

What does cost-optimization do?

It teaches Claude a repeatable approach to lowering cloud costs across AWS, Azure, GCP and OCI. It covers rightsizing, tagging, discounts, budgets and architecture changes, with Terraform examples.

How do I install it?

Use the install box above. The README offers the cloud-infrastructure plugin, which adds 7 more skills and 7 agents, or a skills-only install of just this skill.

Does it connect to my cloud account?

The skill bundles no scripts; it names cost tools such as Cost Explorer and Kubecost. Whether Claude can read your account depends on the CLI or MCP servers you have set up (our note, not from the SKILL.md).

Are the savings numbers current?

They are static text in the SKILL.md, for example reserved instance savings and spot discounts. Confirm current terms with your provider before buying commitments.

Does it work in Claude.ai, Codex or Cursor?

The README documents Claude Code and Codex plugins and a Cursor plugin marketplace, plus skills-only installers for other tools. It does not describe the Claude app.

Is it safe?

The skill bundles no scripts, but its examples include lifecycle rules that delete objects and a checklist item to delete unused resources. Review any Terraform change and any deletion before you apply it.
