Dev details running Terraform validation in AWS Lambda

A developer detailed the challenges of running `terraform validate` within an AWS Lambda function for code evaluation in an LLM agent. The process involves writing generated Terraform code to disk, managing execution environments to prevent cross-run contamination, and handling subprocess calls for formatting and validation. A key issue is `terraform init` requiring network access, which is problematic in Lambda; the solution involves baking provider plugins into the container image at build time to avoid slow downloads and potential network failures.

    I Ran terraform validate Inside a Lambda. Two Things Broke.

    <p>Most agent projects that generate code evaluate it by asking another model whether the code looks correct. I did that for about a week in TerraformAgent before I got tired of it.</p> <p>The failure mode is boring and predictable. The judge reads a <code>.tf</code> file, sees r…
