Use this skill when working with Terragrunt infrastructure configurations. Triggers include: - Setting up a new Terragrunt infrastructure catalog from scratch - Creating or managing Terragrunt stacks (terragrunt.stack.hcl) - Creating units that wrap OpenTofu modules from separate repos - Configuring live infrastructure repositories with root.hcl hierarchy - Setting up remote state backends (S3 with native lockfile or DynamoDB locking) - Multi-account/multi-environment deployments with cross-account role assumption - Working with classic Gruntwork-style live repos (account/region/env hierarchy, _envcommon includes) - Migrating a monolithic Terraform/OpenTofu repo (terralith) to Terragrunt - Exploring or auditing an existing Terragrunt repository (find, list, dag graph) - Wiring unit dependencies (values pattern or autoinclude blocks) - Speeding up clones/fetches or making catalog stacks self-contained with the Content Addressable Store (CAS, update_source_with_cas)
