# Terragrunt (1.x) Single skill for all Terragrunt work, organized as a router: identify the task mode below, read ONLY the listed reference(s), then act. References are grep-friendly — prefer `grep` lookups over reading whole files. ## Hard policy 1. **Post-1.0 CLI only.** Never generate or recommend pre-1.0 forms: `run-all`, `plan-all`, `hclfmt`, `hclvalidate`, `graph-dependencies`, `validate-inputs`, `terragrunt-` prefixed flags, the `skip` attribute, `retryable_errors`, or bare `find_in_parent_folders()` pointing at a root `terragrunt.hcl`. If user code contains these, flag them and propose the 1.x form. **Emit the replacement, never just the ban:** `run --all`, `hcl fmt`, `hcl validate`, `dag graph`, **`hcl validate --inputs`** (add `--strict` to fail on inputs the module does not declare), the unprefixed flag, the `exclude` block, `errors { retry { retryable_errors = [...] } }` (the attribute name is unchanged; what moved is its position, so a bare top-level `retryable_errors` is the pre-1.0 form and the nested one is current), and `find_in_parent_folders("root.hcl")`. > `hcl validate --inputs` is spelled out here because an ablation showed it is the one > banned form this policy was carrying on its own. With the ban removed, every other form > held at zero violations — the surrounding 1.x examples were enough — while > `validate-inputs`, removed in v1.0.0, accounted for **16 of 16** remaining violations. It was the only one
