The website and CLI share this saved 3D game creation workflow. Ask which engine (Unity, Godot, Unreal, Three.js) if unspecified; do not choose silently. create saves a brief without spending. quote(operation=plan) estimates AI preparation, accept(quote_token) starts its durable job ONLY after user approval of the shown price. get returns a persistent operation log, slots, studio_url and the same project to resume. Planning can select an appropriate preset OR compose real engine-compatible modules. A missing preset never means the genre needs a native engine. composition.modules pins all module versions; composition.tasks lists the custom logic still to implement. Assembly is a foundation, not a completed custom game: use the coding agent to finish those tasks on the selected engine (including web/Three.js). After a build, get also returns creatures (the models bound so that no unit is a capsule) and audit { verdict: complete | playable_with_defects | incomplete, headline, fixed (the free fixes applied: models, standard clips, control scheme), defects [{ severity, message, fix { tool, args, credits? } }], next }: show the user the verdict and what is left, work through next (gripforge_game_audit reads it again), and never present a verdict other than complete as a finished game. quote refine with message updates the same plan after approval, preserves selected assets and reviewed work, and persists the conversation. use_reference with slot_id and an owned image asset_id supplies an uploaded concept for visual review. assets searches compatible workspace/community items ranked by the brief and role; select chooses one or sets mode=generate with a prompt. For generation: quote concept, obtain approval, accept, poll get, show the concept, approve_concept only after visual user review; quote generate, obtain approval, accept, poll, show the model in its studio, approve_asset only after visual review. Never infer visual approval from technical success. quote build then accept acquires the selected community assets and binds them to a Game Kit prototype, without generating extra assets. With explicit allow_incomplete=true on the build quote, unreviewed models are excluded and missing slots use module defaults where available or remain empty. Show missing_assets before approval; never imply that an incomplete prototype is finished. Native engine projects still need CLI delivery/import; a web project has a play_url. Revision required for edits. Cancel/retry preserve completed steps. 2D unsupported. No automatic spending, invented asset IDs, or unrelated template substitutions.
