terraform-azurerm-set-diff-analyzer
Analyze Terraform plan JSON output for AzureRM Provider to distinguish between false-positive diffs (order-only changes in Set-type attributes) and actual resource changes. Use when reviewing terraform plan output for Azure resources like Application Gateway, Load Balancer, Firewall, Front Door, NSG, and other resources with Set-type attributes that cause spurious diffs due to internal ordering changes.

Same command for any agent — swap --agent for claude-code, codex, cursor.

# Terraform AzureRM Set Diff Analyzer A skill to identify "false-positive diffs" in Terraform plans caused by AzureRM Provider's Set-type attributes and distinguish them from actual changes. ## When to Use - `terraform plan` shows many changes, but you only added/removed a single element - Application Gateway, Load Balancer, NSG, etc. show "all elements changed" - You want to automatically filter false-positive diffs in CI/CD ## Background Terraform's Set type compares by position rather than by key, so when adding or removing elements, all elements appear as "changed". This is a general Terraform issue, but it's particularly noticeable with AzureRM resources that heavily use Set-type attributes like Application Gateway, Load Balancer, and NSG. These "false-positive diffs" don't actually affect the resources, but they make reviewing terraform plan output difficult. ## Prerequisites - Python 3.8+ If Python is unavailable, install via your package manager (e.g., `apt install python3`, `brew install python3`) or from [python.org](https://www.python.org/downloads/). ## Basic Usage ```bash # 1. Generate plan JSON output terraform plan -out=plan.tfplan terraform show -json plan.tfplan >

How do I install it?
Run `npx skills add github/awesome-copilot --skill terraform-azurerm-set-diff-analyzer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From github/awesome-copilot, a repository with 37,432 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
