Command definition
check.mddescription: Drift detector. Diff SPEC.md against code. Read-only, zero writes. argument-hint: [§V | §I | §T | --all]
Invoke the **check** skill (`skills/check/SKILL.md`). Treat `$ARGUMENTS` as the scope (`§V` default, `§I`, `§T`, or `--all`). Read-only — classify each item HOLD/VIOLATE/UNVERIFIABLE (or MATCH/DRIFT/MISSING/EXTRA for §I), cite file:line evidence, end with remedy hints. Writes nothing. Run it after each build.
A Claude Code plugin that turns natural language into blueprints, blueprints into parallel build plans, and build plans into working software with automated iteration, validation, and cross-model peer review.
