A full-cycle game-development agent for Godot: from a one-line idea to a running, verified build — style-consistent, self-evolving, and runnable under both Claude Code and Codex.
GAT is not a single prompt. It is a small team of role agents running a 13-skill pipeline, backed by a game-architecture knowledge base and a self-evolving memory, that carries a game all the way from design to implementation inside Godot.
It unifies four projects into one workflow:
- a document-driven design pipeline (concept → GDD → art direction → milestones),
- the game-architect knowledge base (30+ references on paradigms and per-system design),
- the game-skill-vfx pipeline (AI skill-effect VFX → Godot sprite sheets),
- and live Godot editor control (build scenes/nodes in a running editor).

⭐ Style-lock — one style, enforced forever. Generate one hero in a "papercut wuxia" look,
and every icon, VFX, and tileset for the next six months must match it — or the game reads as an
asset-flip. GAT freezes your art direction into an enforceable Style Contract
(design/art/style-contract.yaml). Every asset skill (1) refuses to run without it, (2) composes
its prompt as frozen-prefix + your-subject + frozen-suffix with a locked negative/seed, and
(3) passes an audit gate (tools/art_audit.py) that rejects off-palette, wrong-resolution,
or off-family output. Changing the style is a deliberate --relock, never an accident.
→ docs/style-lock.md
⭐ Self-evolving — the toolkit compounds. Every skill reads a shared knowledge base before
work and writes lessons back after. Pitfalls, recipes, patterns, and balance bands accumulate
in knowledge/wiki/; game #10 starts far ahead of game #1. GAT can even propose improvements
to its own skills — through review, never silently. → docs/self-evolving.md

The toolkit is cloned once and shared by all your games. Point a game repo at it:
git clone https://github.com/chenhangcuisg-code/gat ~/gat
# wire a game project to run GAT under both runtimes:
bash ~/gat/install.sh --runtime both --target /path/to/my-game
# Windows: pwsh -File ~/gat/install.ps1 -Runtime both -Target C:\path\to\my-game
cd /path/to/my-game # then run /gat-workflow-start- Claude Code → skills/agents linked into
.claude/, rules inCLAUDE.md. - Codex →
AGENTS.md+~/.codex/prompts/gat-*.mdgenerated from the same source.
One set of SKILL.md files, both runtimes — no fork. → docs/dual-runtime.md
- Godot 4.x (tested 4.6.2 / 4.7); optional Hastur plugin for live editor control.
- Python 3.10+ with
pillow numpy pyyamlfor the style tools. - For skill VFX: a CUDA GPU (open models, no paid APIs). →

gpt-image-2(no GPU needed).

GAT（Godot 智能体团队）不是一句 prompt，而是一个由角色智能体组成的小团队运行一条 13 个技能的流水线，背后有游戏架构知识库与自进化记忆支撑，把一款游戏从设计 一路推进到 Godot 里的实现。
它把四个项目整合进一条工作流：
- 文档驱动的设计流水线（概念 → GDD → 美术方向 → 里程碑）；
- game-architect 知识库（30+ 篇范式与分系统设计参考）；
- game-skill-vfx 流水线（AI 技能特效 → Godot 精灵表）；
- 以及实时 Godot 编辑器操控（在运行中的编辑器里搭场景/节点）。

⭐ 锁风格（Style-lock）——一次定风格，永久强约束。 你用「水墨剪纸武侠」画了一个主角，
之后半年里每一张图标、每一个特效、每一块 tileset 都必须是同一个「画师」的手笔，否则游戏就像
素材拼凑。GAT 把美术方向冻结成可执行的风格契约 design/art/style-contract.yaml：所有出图
技能都会（1）没契约就拒绝生成，（2）把 prompt 组成 冻结前缀 + 你的主体 + 冻结后缀（附带锁定
的负面词/种子），（3）过一道审计门禁 tools/art_audit.py，调色板不符、分辨率不对、跟母版
不像的一律打回重生成。改风格必须显式 --relock，绝不「顺手」漂移。
→ docs/style-lock.md
⭐ 自进化（Self-evolving）——工具越用越强。 每个技能干活前先读共享知识库，干完后把
教训写回去。踩坑、方法、模式、数值区间不断沉淀进 knowledge/wiki/，做到第 10 个游戏时的起点
远高于第 1 个。GAT 甚至能提出对自身技能的改进——但走评审、绝不悄悄改。
