Terraform Module Design Is the Hard Part – So I Built an Agent Skill for It

This article discusses the common pitfalls in Terraform module design, emphasizing that the hardest part is not code generation but making correct design choices about module boundaries, responsibilities, and abstractions. The author explains why generic AI generation is insufficient and introduces their terraform-module-creator agent skill, which focuses on design judgment, principles, and integration with Azure MCP and HashiCorp MCP. The skill produces not just Terraform files but also guidance on module type, boundaries, and flexibility, aiming to prevent common issues like vague responsibilities and over-exposure of provider surfaces. The article is highly relevant to IT/Technology, specifically DevOps and infrastructure-as-code.
