applying-azure-cost-guardrails

applying-azure-cost-guardrails is a skill for Claude Code from alexpizarro/azure-lean-stack-skills. It costs 123 tokens per session (4,100 once invoked), scanned A, original, MIT.

A checklist and audit procedure for keeping Azure deployments within selected low-cost service tiers and usage limits.

In plain words
What is it for?
It is for reviewing Bicep infrastructure, checking consumption pricing, enabling scale-to-zero or database auto-pause, limiting logging storage, and applying storage lifecycle rules.
Why use it?
It helps catch infrastructure settings that can create unnecessary charges, such as always-running containers or databases that never pause.

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

applying-azure-cost-guardrails scanned grade A with 1 finding 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 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/audit-cost-antipatterns.sh, scripts/audit-sku-overrides.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 315 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Applying Azure Cost Guardrails

Consumption-first design defaults + a script that audits existing Bicep for cost regressions. This skill is preventive — for live cost analysis of a running deployment, compose with Microsoft's azure-cost skill.

The canonical guardrails

Every project scaffolded by this plugin inherits these defaults. Verify them when auditing.

1. SWA Free tier in test, Standard only in prod when needed

skuName: environment == 'prod' ? 'Standard' : 'Free'

Standard is $9/month per app. Skip it unless you need custom domains, SLA, or the larger function quota.

2. SQL Serverless with auto-pause

sku: { name: 'GP_S_Gen5_1', tier: 'GeneralPurpose', family: 'Gen5', capacity: 1 }
properties: {
  autoPauseDelay: 15            // minutes before pause
  minCapacity: json('0.5')
  maxSizeBytes: 1073741824      // 1 GB
}

Paused = storage cost only (~$0.10/GB/month). First request after pause takes 30–60s.

3. Container Apps scale-to-zero

scale: {
  minReplicas: 0                // <<< the cost win
  maxReplicas: 3
}
workloadProfileName: 'Consumption'   // never 'Dedicated D4/D8' — those bill per-minute idle

Idle = $0. Use minReplicas: 1 only when cold-start hurts UX.

4. Log Analytics dailyQuotaGb cap

workspaceCapping: { dailyQuotaGb: 1 }

Single most important setting. Without it, a logging bug can ingest 100+ GB overnight.

5. Storage lifecycle rules

Auto-delete temp blobs, age content through Hot → Cool → Cold. See optimizing-azure-blob-storage-cost.

6. Storage Standard_LRS (not GRS/RAGRS unless DR matters)

sku: { name: 'Standard_LRS' }

LRS is half the cost of GRS. Use GRS only when a written DR requirement exists.

7. GHCR over Docker Hub/ACR for non-secret images

GHCR public = $0. ACR Basic = ~$5/mo. Docker Hub anonymous = rate-limited and fragile.

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
