Use when writing, reviewing, or fixing a single SAF/HDF-style InSpec control — STIG, CIS Benchmark, AWS/Azure/GCP best-practice baseline, application baseline, or any profile that emits Heimdall Data Format results. Apply when deciding what "done" means for a control, picking the right InSpec resource instead of raw shell pipelines, framing describe blocks for clear evaluator output, generalizing checks via inputs, attaching the right compliance metadata (CCIs, NIST 800-53, CIS controls, CSF, etc.), or porting controls between vendor baselines (RHEL/AL/Ubuntu/Windows/cloud/k8s).
