Covers Azure-focused modules with KISS/DRY principles, module boundary definition, interface design, and practical file structure generation. Do NOT use for general Terraform coding with no module boundary, provider version upgrades (use terraform-provider-upgrade skill), or non-Terraform IaC. /terraform-module-creator by thomast1906](https://skilld.dev/gh/thomast1906/github-copilot-agent-skills/terraform-module-creator) - [ **/terraform-provider-upgrade**202 Safe Terraform provider upgrades with automatic resource migration, breaking change detection, and state management using moved blocks.
