Changed the definition of "generate"
⟨13 unchanged words⟩ changed nothing is charged and price_changed comes back. Credits paid for an item's draft count toward that item's final (draft + final = the quoted price): confirming the plan_kit price is accepted and only the lower remaining price is charged. The same requestId returns the same jobs and ⟨7 unchanged words⟩
Added "asset_kit", "game_concept", "get_spec" and 1 more (9 tools before, 13 now)
Quote the matching asset kit — No charge here. Plans the assets a saved spec needs (GUI set with its finished screen, icons, thumbnail, props, music) in the spec's style and returns one total in credits plus a kit projectId. Show the user the total; then draft/approve/generate on that projectId exactly as after plan_kit (generate takes confirmCredits). The kit zip includes the spec files. Calling it again returns the same project.
Write a game spec from an idea — No charge. Turns a genre preset, an art-style preset and a one-line idea into a short game spec your coding agent can build from: intent (frozen), plan (milestones with testable done_when, playtest, asset manifest) and state (you update it with update_state). Returns game_spec.json plus GAME_SPEC.md, AGENTS.md and PROMPT.md to save in the project. Names of existing games, characters and brands are removed: specs are original games only. With an API key the spec is saved (specId) for get_spec, update_state and asset_kit.
Read a saved game spec — No charge. The saved spec (all three layers) and its handoff files. Without specId, lists your recent specs.
