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.
Why this skill is useful
Adds a Python script that analyzes Terraform plan JSON output specifically for AzureRM resources, identifying false-positive diffs that the AI wouldn't reliably generate on its own.

What this skill does
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. Basic Usage Troubleshooting python: command not found: Use python3 instead, or install Python ModuleNotFoundError: Script uses only standard library; ensure Python 3.8+ Detailed Documentation scripts/README.md - All options, output formats, exit codes, CI/CD examples references/azurermsetattributes.md - Supported resources and attributes
