Terraform Plan Review with Claude Code: Result JSON Schema

A production playbook for Terraform plan review in cross-industry operations using Claude Code: result json schema, run-scoped inputs, logs, typed results, and artifacts.

Audience: Infrastructure teams

The problem

Infrastructure teams need Terraform plan review to run repeatedly against plan output, modules, policy checks, and deploy notes. In cross-industry operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.

Implementation path

Define the outer result contract once, let the Terraform plan review skill own body.data, and reject terminal output that does not match the expected schema.

Tradeoffs and failure modes

Schema enforcement adds upfront design work, but removes prompt parsing from the product surface. For Terraform plan review, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.

  "schema_version": "argo.result.v1",
