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.
Frozen — compressed spec-driven development plugin for Claude Code. Still works; active development moved to JuliusBrussee/caveman.
Other commands on ck.
deepen
Spare-budget design pass. Make one shallow module deep — smaller interface, behavior held, tests green before & after.
grill
Sharpen a fuzzy idea into §G/§C before spec. Calibrated interrogation, one question at a time.
research
Gather external knowledge into §R so build grounds in facts, not hallucinations. Every finding cites a source.
review
Adversarial senior review of the spec before build. Refute, don't rubber-stamp. Ends in a go/no-go gate.
