    "incantation": "When a stack’s units need dependencies or shared parent-folder configuration, declare unit dependencies in `autoinclude` using generated component paths, and add an `include` block to `terragrunt.stack.hcl`. In Terragrunt v1.1.0, these features are enabled by default; no experiment flag is required.",
    "examples": [
      "unit \"vpc\" {\n  source = \"<catalog-source>/units/vpc\"\n  path   = \"vpc\"\n}\n\nunit \"app\" {\n  source = \"<catalog-source>/units/app\"\n  path   = \"app\"\n\n  autoinclude {\n    dependency \"vpc\" {\n      config_path = unit.vpc.path\n    }\n    inputs = {\n      vpc_id = dependency.vpc.outputs.vpc_id\n    }\n  }\n}",

    "gotchas": [
      "Version: v1.1.0",
      "unit.<name>.source (required): Source for the unit configuration.",
      "unit.<name>.path (required): Relative generated path for the unit; exposed as `unit.<name>.path` to sibling component references.",
      "autoinclude: Unlabeled block inside a unit or stack; its body is injected into that generated component’s configuration. It takes no arguments. For unit dependencies, declare `dependency` and `inputs` here.",
      "dependency \"<name>\".config_path (required): Path to the dependency unit or stack. It can reference a sibling’s generated path, such as `unit.vpc.path` or `stack.network.path`.",
      "inputs: Map of inputs; the example reads a dependency output with `dependency.vpc.outputs.vpc_id`.",
      "include \"<label>\".path (required): Path to the included stack file, relative to the directory of the stack file declaring the include. The included file may declare unit and stack blocks.",
      "Prerequisite: The `autoinclude` feature is for HCL `terragrunt.stack.hcl` files; JSON stack files declaring it fail generation.",
      "Prerequisite: In v1.1.0, the `stack-dependencies` experiment is no longer required; the release says the feature is enabled by default.",
      "Stack dependencies are limited to units depending on stacks; stacks cannot depend on stacks or units."

  "why_it_matters": "Wire units in a generated stack to their dependencies and add shared configuration to stack definitions.",
  "before": "Before stack dependencies, users defined dependency blocks in catalog units and passed dependency paths through `values`.",
