sdd-flow

Use this skill when the user wants to start or drive a project with Spec-Driven Development (SDD) — in any language they ask in ("start a project with SDD", "spec-driven flow", "do it phase by phase with a spec", "empezar con SDD", "flujo spec-driven"). Explains the 8 phases, which artifact each one leaves, and which slash command runs it, plus the cross-cutting /sdd:docs command, and brings the base templates to copy into the project.
