name: CDISC CORE
description: >-
  CDISC CORE (Checks and Rules Engine) is CDISC's first-party, open-source command-line conformance validator.
  It reads rules and standards metadata from the CDISC Library API with an API key, caches them locally, and
  validates SDTM / SEND / ADaM / CDASH / TIG datasets against the published CORE rules. It is the only CDISC
  command-line surface; there is no CLI for the Library API itself.

note: >-
  The command set is transcribed verbatim from the published CLI reference (its five top-level command
  headings: validate, update-cache, list-rules, list-rule-sets, list-ct). Only `validate` has its full flag
  surface recorded above — it is the command an integrator actually runs. The reference also documents
  environment-variable equivalents for most flags, custom rules/standards loading, and Dask-based large
  dataset processing.
