What it does
Optimizing Cloud Costs is an agent skill from jeremylongshore/tons-of-skills-marketplace. Execute use when you need to work with cloud cost optimization. This skill provides cost analysis and optimization with comprehensive guidance and automation. Trigger with phrases like "optimize costs", "analyze spending", or "reduce costs".
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts, reference files and assets (for example `assets/README.md`, `assets/optimization_recommendation_template.json` and `references/README.md`). Compatibility notes: Designed for Claude Code
It sits in DevOps & Cloud, covering Cloud cost optimization. It works with Google Cloud, Amazon Web Services and Terraform. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
When your agent uses it
- You need to work with cloud cost optimization
- With phrases like optimize costs
- Analyze spending
Example prompts
- “optimize costs”
- “analyze spending”
- “reduce costs”
- “/optimizing-cloud-costs”
Requirements
- Python 3
- Compatibility (from SKILL.md): Designed for Claude Code
- Pre-approved tools (allowed-tools): Read, Write, Edit, Grep, Glob, Bash(aws:*), Bash(gcloud:*), Bash(az:*)
Workflow steps
10 steps, taken from the first numbered list in SKILL.md.
- Pull current cost data using cloud cost APIs (aws ce get-cost-and-usage, gcloud billing budgets list)
- Identify the top 10 cost drivers by service, region, and resource tag
- Detect idle resources: instances with < 5% average CPU over 14 days, unattached EBS volumes, unused Elastic IPs, orphaned snapshots
- Recommend rightsizing: compare instance utilization against available instance types and suggest downsizing
- Evaluate reserved instance or savings plan coverage against on-demand spend; recommend commitments for steady-state workloads
- Identify spot/preemptible candidates: stateless, fault-tolerant workloads (batch jobs, CI runners, dev environments)
- Review storage costs: recommend S3 Intelligent-Tiering, lifecycle policies for infrequent access, or Glacier for archives
- Generate Terraform/IaC changes to implement approved optimizations
- Set up budget alerts with thresholds at 50%, 80%, and 100% of monthly budget
- Create a cost optimization report summarizing findings, savings estimates, and implementation priority
What it can do on your machine
Read from SKILL.md and the folder at commit 80f86df. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGrepGlobBash(aws:*)Bash(gcloud:*)Bash(az:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
awsgcloud
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
docs.aws.amazon.comcloud.google.comlearn.microsoft.comfinops.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Designed for Claude Code
From compatibility in the SKILL.md frontmatter.
Context cost
Optimizing Cloud Costs loads about 1.1k tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 468 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Optimizing Cloud Costs
Overview
Analyze cloud spending across AWS, GCP, and Azure to identify waste, recommend rightsizing, and generate cost-saving configurations. Covers reserved instances, spot/preemptible workloads, storage tiering, idle resource cleanup, and budget alerting using cloud-native cost management APIs.
Prerequisites
- Cloud provider CLI authenticated with billing/cost-explorer read access
- AWS:
ce:GetCostAndUsage,ec2:DescribeInstances,cloudwatch:GetMetricDatapermissions - GCP: Billing Account Viewer and Compute Viewer roles
- Azure: Cost Management Reader role
- Access to current infrastructure-as-code (Terraform, CloudFormation) for rightsizing changes
- At least 30 days of billing data for meaningful analysis
Instructions
- Pull current cost data using cloud cost APIs (
aws ce get-cost-and-usage,gcloud billing budgets list) - Identify the top 10 cost drivers by service, region, and resource tag
- Detect idle resources: instances with < 5% average CPU over 14 days, unattached EBS volumes, unused Elastic IPs, orphaned snapshots
- Recommend rightsizing: compare instance utilization against available instance types and suggest downsizing
- Evaluate reserved instance or savings plan coverage against on-demand spend; recommend commitments for steady-state workloads
- Identify spot/preemptible candidates: stateless, fault-tolerant workloads (batch jobs, CI runners, dev environments)
- Review storage costs: recommend S3 Intelligent-Tiering, lifecycle policies for infrequent access, or Glacier for archives
- Generate Terraform/IaC changes to implement approved optimizations
- Set up budget alerts with thresholds at 50%, 80%, and 100% of monthly budget
- Create a cost optimization report summarizing findings, savings estimates, and implementation priority
Output
- Cost analysis report with per-service breakdown and savings recommendations
- Terraform/CloudFormation changes for rightsizing and reserved instance purchases
- S3 lifecycle policy configurations for storage tiering
- Budget alert configurations (CloudWatch, GCP Budget, Azure Cost Alerts)
- Cleanup scripts for idle resources (with dry-run mode for safety)

Error Handling
| Error | Cause | Solution |
|---|---|---|
Access Denied on Cost Explorer API | Missing ce:* IAM permissions | Attach the AWSBillingReadOnlyAccess managed policy to the IAM user/role |
No billing data available | Account is too new or cost export not enabled | Enable Cost Explorer (takes 24h to populate) or set up CUR (Cost and Usage Report) |
Rightsizing recommendation breaks workload | Instance too small for peak load | Base sizing on P95 utilization, not average; keep a 20% headroom buffer |
Spot instance terminated mid-job | Spot capacity reclaimed by provider | Use spot fleet with diversified instance types and implement checkpointing |
Budget alert not firing | SNS topic or notification channel misconfigured | Verify SNS subscription is confirmed and test with a low threshold |
Examples
- "Analyze AWS costs for the last 3 months, identify the top waste areas, and generate a cleanup script for unattached EBS volumes and unused Elastic IPs."
- "Compare on-demand EC2 spend against Savings Plans pricing and recommend 1-year commitments for steady-state workloads."
- "Create S3 lifecycle policies to move objects older than 90 days to Glacier and delete after 365 days across all buckets tagged
env:production."
