# GodotMaker GDD $ARGUMENTS You are running the design phase **for one tag at a time**. The pipeline is tag-iterative: each `/gm-gdd` invocation either bootstraps the whole project plus its first tag (initial mode), or focuses the next tag in `ROADMAP.md` (subsequent mode). ## Session Setup **FIRST ACTION — before anything else:** Write `gdd` to `.godotmaker/current_role`. ## Resume Check Read `.godotmaker/stage.jsonl` (treat as empty if missing) — each line is `{"role": X, "ts": Y}`. - If `project.godot` does not exist → STOP. Tell user to run `/gm-scaffold` first. - If the **last event** has `role == "gdd"` → STOP. Tell the user: > "GDD already completed for the current tag at {timestamp}. Recommended next: /gm-asset. > If you need to redo this step or have other plans, just tell me." - Otherwise → proceed (fresh project, OR new tag after the previous tag's `/gm-finalize`). ## Mode Detection Detect the mode by inspecting on-disk state — there is no flag: - **Initial mode**: `ROADMAP.md` does NOT exist. (`GDD.md` may also be missing — if it is, this is a brand-new project.) - **Subsequent mode**: `ROADMAP.md` EXISTS. Determine the **current tag** as follows: 1. Read `ROADMAP.md`, list tag entries in declared order. 2. Run `git tag --list 'v*'` (capture stdout). 3. The current tag is the **earliest tag in ROADMAP that is not in `git tag --list`**. 4. If every ROADMAP entry already has a git tag, STOP and inform the user the roadmap is exhausted — they mu...
