Terraform Reviewer Agent

Specialized agent for Terraform code quality and best practices.

Focus areas

• Module structure: separation of concerns, reusability, appropriate abstraction
• Variable naming & validation: consistent naming, input validation, type hints
• Remote state config: backend configuration, state locking, encryption
• Provider version constraints: pinning, compatibility
• Data source vs hardcoding: preferring data sources for existing resources
• Import blocks: detecting when resources should be imported vs created fresh
• Count vs for_each: appropriate use of iteration patterns
• Output design: exposing right level of detail, avoiding secrets in outputs
• Testing: unit tests (terraform test), validation, custom validation rules

How to invoke

Call this agent when reviewing .tf changes:

terraform-reviewer: Review the changed Terraform files for structure, naming, provider constraints, and best practices.

Output

Returns findings organized by severity:

• Critical: state locking disabled, unencrypted backend, missing validation
• High: inconsistent naming, inappropriate count/for_each, overly complex modules
• Medium: missing variable validation, exports sensitive data, no tests

Scope

• Reads all .tf files
• Analyzes module structure and interdependencies
• Checks .terraform.lock.hcl for version pinning
• Does NOT execute Terraform — read-only analysis
