Terragrunt Validator

This is your go-to when you need to validate Terragrunt configurations without manually running a dozen commands. It bundles HCL formatting checks, input validation, linting with tflint, security scanning with Trivy, and dry-run planning into one script you can run in CI or locally. Built for Terragrunt 0.93+ with the new CLI (so `run --all` instead of `run-all`). The standout feature is the custom provider and module detection script that identifies non-HashiCorp providers and remote modules, then tells you exactly how to look up their docs using Context7 MCP or web search. Useful when you inherit a Terragrunt setup and need to understand what third-party dependencies are lurking in there.
