orca-cloud-cost-optimizer

orca-cloud-cost-optimizer is a skill for Claude Code from orcasecurity/orca-skills. It costs 113 tokens per session (4,811 once invoked), scanned A, original, MIT.

A cloud spending review based on Orca Security’s records of AWS, Google Cloud, and Microsoft Azure resources. It compares current setups with cheaper options using public pricing and identifies specific assets to change.

In plain words
What is it for?
Finding oversized or unused compute, database, storage, networking, and serverless resources, then prioritising cost-cutting actions with asset details and commands.
Why use it?
It replaces vague advice about reducing cloud costs with evidence about individual resources, their configurations, and estimated savings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

orca-cloud-cost-optimizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Cloud Cost Optimizer

Answers the question: "Where are we overspending and what should we fix first?"

Analyzes all cloud assets via Orca Security MCP data to identify actionable cost reduction opportunities across compute, databases, storage, networking, and serverless resources. Delivers a dual-audience report: executive summary with total savings range, and per-asset action plan with specific IDs, Orca links, console links, CLI commands, and projected monthly savings.

The key rule: never generalize. "You have some oversized instances" is useless. "Your db-prod-us-east-1 RDS instance is a db.r5.4xlarge ($1,752/month) and could be db.r5.2xlarge ($876/month)" is what this report delivers.

Usage

/orca-cloud-cost-optimizer

Or natural language:

  • "give me a cost optimization report"
  • "where are we wasting money on cloud?"
  • "how do we cut our AWS bill?"
  • "find unused resources"
  • "what can we rightsize?"
