Command definition
deepen.mddescription: Spare-budget design pass. Make one shallow module deep — smaller interface, behavior held, tests green before & after. argument-hint: [module/path | "improve the design"]
Invoke the **deepen** skill (`skills/deepen/SKILL.md`). Pick the single shallowest module the spec touches, diagnose the design defect at file:line, research a deeper shape (hand the external case to research → §R), and propose §I/§V/§T edits to spec. Behavior is sacred — full suite green before AND after. Run only when the build is green and there is token budget to drain.
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.
