The file

We split this skill into the rules it gives an agent

2 rules. About 0 are common, 0 are distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈0

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Cloud Run deployment / right-sizing: Use deployment-engineer agent with sizing flags from reference/gcp-cost-optimization.md

    line 95
  2. Very specific:

    Architecture decisions (multi-region): Use architecture-design skill + architect agent for ADR

    line 96

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

GCP FinOps

Iron Law

NO GCP COST WORK WITHOUT:
1. Verifying cost allocation labels are applied to all resources (project, service, environment)
2. A billing budget alert configured before committing spend
3. Using terraform-specialist agent for Committed Use Discount reservations (never manual console)

GCP Cost Tools — Quick Reference

  • GCP Billing Console — console.cloud.google.com/billing — cost breakdown by project, service, label
  • Cloud Cost Management — cost table, cost breakdown report, budget history
  • GCP Recommender — automated right-sizing, idle resource, and CUD recommendations (gcloud recommender)
  • Active Assist — umbrella for all Recommender signals; surfaces in Cloud Console dashboard
  • Committed Use Discounts — 1-yr (~37% off) or 3-yr (~55% off); resource-based or spend-based
  • Sustained Use Discounts — automatic for Compute Engine VMs running >25% of month; no action needed

Cross-References

  • Terraform resources (CUD, budgets, SQL HA): Dispatch terraform-specialist agent to apply patterns from reference files
  • Cloud Run deployment / right-sizing: Use deployment-engineer agent with sizing flags from reference/gcp-cost-optimization.md
  • Architecture decisions (multi-region): Use architecture-design skill + architect agent for ADR
  • Security review (WIF, IAM): Dispatch security-reviewer after any infrastructure change

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
