What problem does it solve? When a correction is needed in a Terragrunt migration, the same change must be propagated to every terragrunt.hcl file across all populated environments, which is tedious and error-prone to do by hand. ## Core Features & Use Cases - Bulk Find/Replace: Replace strings across all terragrunt.hcl files using the migration_bulk_replace tool. - Input Management: Update an existing input value or add a new input across selected services with migration_bulk_update_input and migration_bulk_add_input. - Dry-Run Safety: Always runs in dry-run mode first, showing exact before/after diffs and file counts, and requires explicit approval before applying. - Use Case: You need to change the provider version constraint from ~> 3.0 to ~> 4.0 in every environment; the skill dry-runs the change, shows all affected files, and applies it only after your confirmation. ## Quick Start Ask the assistant to apply a bulk fix by providing the target repository path and a description such as "change provider version from ~> 3.0 to ~> 4.0 across all terragrunt.hcl files".
