sarj-iac-lint
Custom Terraform / IaC lint rules — stdlib only, line/block based, pre-commit-friendly. Mined from recurring infra review comments across the org.
uv tool install sarj-iac-lint
Rules
| Code | Rule | What it flags |
|---|---|---|
| SARJ201 | require-deletion-protection |
A stateful resource (Cloud SQL, GKE, BigQuery, Spanner, AlloyDB, Bigtable, RDS, DynamoDB, ElastiCache, DocumentDB, Neptune, Azure databases, Cosmos DB, ...) without deletion_protection = true. |
| SARJ202 | no-comment-cruft |
Commented-out Terraform/HCL and section-banner / divider comments. |
| SARJ203 | require-prevent-destroy-on-irreplaceable |
A bucket, Secret Manager secret, or artifact registry — which expose no deletion_protection argument at all — without lifecycle { prevent_destroy = true }. |
.tf, .hcl, and .tfvars files are scanned by all rules; .yaml/.yml
(Helm/k8s/Compose) are scanned by no-comment-cruft for banners only.
Pre-commit
- repo: https://github.com/sarj-ai/standards
rev: iac-v0.2.0
hooks:
- id: sarj-require-deletion-protection
- id: sarj-no-comment-cruft-iac
- id: sarj-require-prevent-destroy-on-irreplaceable
CLI
sarj-iac-lint check --rule require-deletion-protection iac/
sarj-iac-lint list-rules
Diagnostic format is path:line:col: CODE message — Ruff-compatible.
--exit-zero reports without failing (warn mode).
Adoption
All three rules have ~zero false positives — run them as hard (blocking) hooks.
require-deletion-protection treats variable/expression-gated protection
(deletion_protection = var.enabled) and lifecycle { prevent_destroy = true }
as protected — only a literal = false or a total absence is flagged. Protection
must sit on the resource itself: a flag nested in settings { ... } is the
API-side switch and does not stop terraform destroy.
require-prevent-destroy-on-irreplaceable covers the stores SARJ201 cannot,
because they have no protection argument to check. It exempts anything declared
disposable via force_destroy, and any secret whose value a *_secret_version
resource in the same file reconstructs.
Suppression
Inline # sarj-noqa: SARJ201 — <reason> on the offending line (the resource
line for SARJ201 and SARJ203).
