Command definition
build.mddescription: Plan-then-execute against SPEC.md. Native Claude Code loop, no sub-agents. argument-hint: [§T.n | --all | --next]
Invoke the **build** skill (`skills/build/SKILL.md`). Treat `$ARGUMENTS` as the target (`§T.n`, `--next`, or `--all`). Plan in native plan mode, name the exact test that proves each §V touched (verification contract), read §R for external facts, execute, and auto-invoke backprop on failure. High blast radius? Suggest `/ck:review` first. Build only flips §T status; other spec edits route through spec.
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.
