Agent-Oriented Terraform#

Most Terraform code is written by humans for humans. It favors abstraction, DRY principles, and deep module nesting — patterns that make sense when a human maintains a mental model of the codebase. Agents do not maintain mental models. They read code fresh each time, trace references to resolve dependencies, and reason about the full resource graph in a single context window.

The patterns that make Terraform elegant for humans make it expensive for agents. Deep module nesting multiplies the files an agent must read. Variable threading through three layers of modules hides dependencies behind indirection. Complex for_each over maps of objects creates resources that are invisible until runtime. The agent spends most of its context on navigation, not comprehension.
