Game Design
ericrisco/rsc-harness
A skill your agent uses when designing or repairing what makes a game fun — verbs and mechanics, moment-to-moment/session/meta loops, progression, economy faucets and sinks, difficulty curves…
Builds a risk-matched whitebox or an approved production game candidate from a game design for its target runtime, with replayable evidence.

What it does
This skill, documented in Chinese, builds a runnable game candidate from an approved design in one of two stages. The whitebox stage tests the riskiest design question in the form that exposes it, and the production stage implements the approved game design and art direction for the target runtime named in the product brief. It must not redo concept, level or art direction during the build.
Inputs are the game design file and, for a full candidate, an art direction file; missing product decisions go back to their owners. The agent declares a build stage and a build path (template or custom), compresses the product boundary, experience facts and completion evidence into a short build brief, and implements a minimal complete core loop of start, real input, state change, result and restart. When a generative model is used, it only interprets input and results while a rules engine owns what gets committed.
Failures are kept replayable with saved initial state, input paths and fixed seeds. Optional contracts cover Blender assets, playable model rules, voice production and generative media. Production adds one authoritative verification command so a QA skill can walk a clean start, core action, designed result and restart, and the output is a build brief plus the candidate.
When your agent uses it
- Prototyping the riskiest question in a game design as a whitebox
- Implementing an approved game design for its target runtime
- Writing a minimal build brief from a design document
- Making a game candidate replayable so QA can verify it
Example prompts
- “Prototype the riskiest design question from GAME_DESIGN.md as a whitebox.”
- “Turn the approved game design and art direction into a runnable production candidate.”
- “Write the build brief for this design and build the candidate for the target runtime in the product brief.”
Requirements
- A GAME_DESIGN.md file, plus ART_DIRECTION.md for a full production candidate
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- 先实现一个最小但完整的核心循环：启动、真实输入、状态变化、结果和重开。范围不足时修范围，
- 实现 GAME_DESIGN 的状态、动作与结果；使用生成模型时，模型只解释输入和结果，规则器拥有提交权。
- 保留能复现问题的初态与输入路径，涉及随机性时固定 seed；修订后重放失败路径与相邻反例。
- 回写实际工具链、install/build/start 命令和版本；未知值写 NOT_AVAILABLE: 原因，不猜。
What it can do on your machine
Read from SKILL.md and the folder at commit 03feee9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Game Build From Design loads about 661 tokens when it runs, and up to ~3.4k if it reads all its reference files. Until then it costs about 127 tokens; SKILL.md has 128 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Build a risk-matched whitebox or the approved production game for its target runtime. Turn GAME_DESIGN, and ART_DIRECTION when production begins, into a minimal BUILD_BRIEF and a runnable candidate that can be iterated with replayable evidence. Use for prototype the riskiest design question, implement the approved game design, or turn this design into a running game. 游戏构建执行。先按最大风险做白盒，或在正式生产时把批准后的 GAME_DESIGN 与 ART_DIRECTION 压缩成最小 BUILD_BRIEF，在目标运行环境中实现可运行候选并用可回放证据迭代。用于验证高风险设计问题、构建游戏原型或实现批准方案。
游戏构建执行
保护已批准的体验边界；正式生产时再保护已批准的美术边界。驱动实现模型完成真实可玩的候选，不在 构建阶段重新做概念、关卡或美术方向。
读取 build-brief-contract.md。白盒阶段必须已有 GAME_DESIGN.md；
完整候选还必须已有 ART_DIRECTION.md。缺产品决定时回对应 owner，不在 BUILD_BRIEF 就地发明。
产物语言由 PRODUCT_BRIEF.md 锁定；未锁定时跟随对话语言，不默认产出中文。
目标与自由
按 PRODUCT_BRIEF 锁定的平台、生产引擎、目标运行时、显示/输入、范围、分级和联网边界交付。
目标工具链不可用时不得自动改做网页；只有 brief 已批准替代运行时才可使用，并分开记录
targetRuntime、testedRuntime 与未覆盖项。
正式生产继承 ART_DIRECTION.md 的可观察视觉约束与批准目标图，在实际运行中验证焦点资产。
BUILD_BRIEF 只压缩产品边界、必须保真的体验事实、运行方式与完成证据，实现细节交给实现模型。
先声明 buildStage: whitebox|production 与 buildPath: template|custom。已有交互语法只有在能保留原作
独有动作、代价和世界回应时才采用；实时手感、空间、视线、物理或模板覆盖不了的核心动词走 custom。
白盒也必须选择能验证最大风险的形态，不能把所有项目降成文游。
当前会话能编码时直接实现；外部模型不可用时只交付构建说明，不声称游戏已生成。不要发送与原型 无关的完整受版权保护原文。
按能力读取可选合同
- 已选择 Blender 制作或修改可编辑三维资产时，读取 blender-asset-workflow.md； 不因项目是 3D 就默认采用 Blender 或安装 MCP。
- 采用生成式自由输入、知识权限、事件回放、存档迁移或
signature_command时，读取 playable-model-contract.md 的相关部分。 - 语音策略不是
none时读取 tts-production-contract.md。 - 实际采用动态媒体时读取 generative-media-pipeline.md。
共同构建循环
- 先实现一个最小但完整的核心循环：启动、真实输入、状态变化、结果和重开。范围不足时修范围， 不先堆审计材料。
- 实现 GAME_DESIGN 的状态、动作与结果；使用生成模型时，模型只解释输入和结果，规则器拥有提交权。
存在
signature_command时再执行可选合同的专属边界。 - 保留能复现问题的初态与输入路径，涉及随机性时固定 seed；修订后重放失败路径与相邻反例。
- 回写实际工具链、install/build/start 命令和版本；未知值写
NOT_AVAILABLE: 原因，不猜。 实际候选与 GAME_DESIGN、ART_DIRECTION 的事实描述不符时，交回对应 owner 修订或在 BUILD_BRIEF 标明冲突， 不留下描述已不存在的玩法、表现或声音的文档。
whitebox 到此按 build-brief-contract「完成证据」运行最窄检查并交回 design owner；设计修订后
重放受影响路径，直到最大风险已被实际暴露或当前方向被否决。
production 继续：
- 提供一条权威验证命令和最小可观察状态，使
game-qa能一次走完clean start → 核心动作 → 设计结果 → restart。 - 运行最窄的开发检查与启动 smoke，修复构建失败、阻断日志、资源失败和崩溃；替代运行时未覆盖的 目标平台输入、性能、打包或设备项写入 limitation。
- 达到 brief 的
targetFinish；更高完成度只处理已批准的焦点资产和招牌时刻，不制造与可玩闭环 无关的发布审计。 - 交给
game-qa；诊断、复跑与事实源规则见契约「完成证据」。
输出
生成 build/BUILD_BRIEF.md 与实际候选；production 还生成权威验证入口。截图、录制与 raw trace 只保留
调试所需的最小集合。
