Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.00821 |
| Opus 5.5 | $0.00015 | $0.00328 |
| Sonnet 5.5 | $0.00007 | $0.00164 |
| Haiku 4.5 | $0.00004 | $0.00082 |
Grade A, and why
prototype scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
当此技能被调用时：
-
读取概念描述来自参数。识别此原型必须回答的核心问题。如果概念模糊，在继续之前明确陈述问题。
-
读取 CLAUDE.md 获取项目上下文和当前技术栈。了解所使用的引擎、语言和框架，以便原型使用兼容的工具构建。
-
创建原型计划：用 3-5 个要点定义最小可行原型的样子。核心问题是什么？回答它所需的最少代码量是多少？什么可以跳过？
-
创建原型目录：
prototypes/[concept-name]/，其中[concept-name]是从概念派生的短 kebab-case 标识符。 -
在隔离目录中实现原型。每个文件必须以以下内容开头：
// PROTOTYPE - NOT FOR PRODUCTION // 问题：[正在测试的核心问题] // 日期：[当前日期]标准有意放宽：
- 可以随意硬编码值
- 使用占位资源
- 跳过错误处理
- 使用最简单可行的方案
- 复制代码而非从正式代码导入
-
测试概念：运行原型。观察行为。收集可测量的数据（帧时间、交互次数、手感评估）。
-
生成原型报告并保存到
prototypes/[concept-name]/REPORT.md：
## 原型报告：[概念名称]
### 假设
[我们预期为真的内容 — 我们要回答的问题]
### 方法
[我们构建了什么、花了多长时间、走了哪些捷径]
### 结果
[实际发生了什么 — 具体观察，而非意见]
### 指标
[测试期间收集的任何可测量数据]
- 帧时间：[如相关]
- 手感评估：[主观但具体 — "200ms 延迟时响应感觉迟钝"而非"感觉不好"]
- 玩家操作次数：[如相关]
- 迭代次数：[尝试了多少次才成功]
### 建议：[推进 / 转向 / 放弃]
[用证据解释建议的一段话]
### 如果推进
[从原型到正式实现需要改变什么]
- 架构要求
- 性能目标
- 与原设计的范围调整
- 预估正式开发工作量
### 如果转向
[结果建议的替代方向]
### 如果放弃
[为什么此概念不可行以及我们应该怎么做]
### 经验教训
[影响其他系统或未来工作的发现]
- 输出摘要给用户：核心问题、结果和建议。附上完整报告的链接
prototypes/[concept-name]/REPORT.md。
重要约束
- 原型代码绝不能从正式源文件导入
- 正式代码绝不能从原型目录导入
- 如果建议是推进，正式实现必须从头编写 — 原型代码不会被重构为正式代码
- 原型总工作量应控制在相当于 1-3 天的工作量内
- 如果原型范围开始膨胀，停下来重新评估问题是否可以简化
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 1mo ago First seen · 88 lines · 37 tokens per session scan A 965b3d4c2e21
prototype is a skill published in the GitHub repository pixel-cellar/Claude-Code-Game-Studios (361 stars, last pushed 6mo ago), licensed MIT. It adds 37 tokens to every session and 821 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
