Azure WAF Pillar Review

Azure WAF Pillar Review is a skill for Claude Code, Codex from niels-emmer/myace. It costs 37 tokens per session (887 once invoked), scanned A, original, MIT.

An Azure Well-Architected Framework review checks a planned change to Microsoft’s cloud platform against reliability, security, cost, operations, and performance concerns. It uses concrete Azure services and settings rather than only general design advice.

In plain words
What is it for?
Use it before adding resources or materially changing how an Azure workload is reached, scaled, secured, monitored, or billed. Cosmetic changes such as tags or variable renames generally do not need it.
Why use it?
It helps reveal single points of failure, unnecessary spending, weak protection, difficult operations, and performance limits before a change is completed. The review focuses attention on the parts of the design most likely to affect the workload.

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

Azure WAF Pillar Review 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 12d 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.

Purpose

The Azure Well-Architected Framework (WAF) is Microsoft's set of design principles for building reliable, secure, cost-optimized, operationally excellent, and performant workloads on Azure. This skill is the Azure-specific companion to iac-expert's generic well-architected-review skill: it maps each pillar to the concrete Azure services and decisions that actually move the needle, so a review checks real Azure constructs rather than abstract principles.

When to use it

Before calling any nontrivial Azure infrastructure change done — new resources, materially changed configuration, anything that affects how the workload is reached, scaled, secured, or paid for. Skip it for genuinely cosmetic changes (a tag fix, a variable rename with no resource impact).

The pillars, and what to actually check in Azure

Reliability. Does the resource have a single point of failure it didn't have to have? Consider availability zones (zone-redundant storage, zonal VMs, zone-redundant App Service plans), availability sets for legacy VMs, and redundancy tiers (LRS vs. ZRS vs. GRS for storage). If it fails, what notices and how does recovery happen — automatically (Azure Monitor alerts, autoscale, failover) or does someone have to intervene? Does the change affect an existing backup path (Azure Backup, geo-replication, traffic-manager/front-door failover)?

Security. Does this follow private-by-default networking (private endpoints, VNet integration, no public IPs) and managed-identity-over-secrets? Does it grant any new RBAC permission, and is it scoped to least privilege rather than a broad Contributor/Owner role? Does it introduce or remove a documented exception? Is Defender for Cloud posture and Azure Policy coverage still intact?

Cost optimization. Does the resource size/tier match actual expected load, or is it a guess to revisit after real usage data? Is there a cheaper tier or pricing model (serverless/consumption vs. provisioned, reserved instances or Azure savings plans vs. pay-as-you-go) that fits the workload's actual traffic pattern? Is spend attributable to a specific cost-center tag so it shows up correctly in Azure Cost Management?

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.

Azure WAF Pillar Review is a skill published in the GitHub repository niels-emmer/myace (1 stars, last pushed 5d ago), licensed MIT. It adds 37 tokens to every session and 887 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
