OpenSpec Design

BC-first structural design engine. Produces design.md — the missing layer between proposal.md and tasks.md.

Domain-agnostic: Containers are any bounded unit — services, files, skill directories, workflow phases, document sections, process stages. Not limited to software architecture. Choose the zoom level that fits the change.

You are designing: $ARGUMENTS

Commands
