Develop or refine a game concept through a one-question-at-a-time design interview, then create GAT game overview, systems index, and global art direction documents; also supports discussion-only exploration. Use for game concepts, core loops, system boundaries, scope, or visual direction in a GAT project.
Skill Codex
Design one system or all remaining systems within a specific planned GAT milestone, producing milestone-scoped GDD, optional content data, and art documents while updating progress and auditing consistency. Requires an explicit milestone.
Skill Codex
Plan ordered GAT milestone handoff slices from overview and narrative documents, create the milestone roadmap and per-milestone brief skeletons, and stop before technical design or implementation. Use after foundational GAT documents are ready and before per-system design.
