Use when designing or repairing a CoGames-style game and the main risk is that the rules, map, roles, or play loop do not yet match the real game or prompt closely enough.
Use when creating a new mettagrid game from scratch and you need the design-first workflow that writes the rules contract, checks engine fit, and hands a clean build plan to `cg.game.build-game`.
Use when a CoGames-style game already works visually and mechanically and now needs to be split into a composable variant registry, dependency tree, and optional curriculum tree without regressing the default game.
Use when implementing or overhauling a CoGames-style game once the target contract is known, including scaffold, registration, mechanics, assets, and variant factoring.
Use when designing or repairing a CoGames-style game and the main risk is that the rules, map, roles, or play loop do not yet match the real game or prompt closely enough.
Use when a CoGames-style game is mechanically working but still has missing, placeholder, wrongly themed, or non-namespaced art, terrain, or atlas entries.
