design-review

design-review is a skill for Claude Code from pixel-cellar/Claude-Code-Game-Studios. It costs 0 tokens per session (911 once invoked), scanned A, original, MIT.

A checklist-based review for game design documents, which describe how a game should work. It checks whether the document is complete, consistent, clear enough to build, and aligned with the project's standards.

In plain words
What is it for?
Use it to review a game concept, game design document, or related system specification. It checks formulas, edge cases, dependencies, performance concerns, balance risks, and acceptance criteria.
Why use it?
It helps catch missing rules, contradictions, unclear details, and conflicts with other game systems before programmers start work.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

design-review 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 7d 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

已将 .claude/skills/design-review/SKILL.md 翻译为中文:


name: design-review description: "审查游戏设计文档的完整性、内部一致性、可实现性以及对项目设计标准的遵循情况。在将设计文档交付给程序员之前运行此技能。" argument-hint: "[设计文档路径]" user-invocable: true allowed-tools: Read, Glob, Grep

当此技能被调用时:

  1. 完整阅读目标设计文档

  2. 阅读主配置文件 CLAUDE.md 以了解项目上下文和标准。

  3. 阅读目标文档引用或暗示的相关设计文档 (检查 design/gdd/ 中的关联系统)。

  4. 按照设计文档标准清单进行评估

    • 包含概述(Overview)章节(一段式总结)
    • 包含玩家幻想(Player Fantasy)章节(期望的感受)
    • 包含详细规则(Detailed Rules)章节(无歧义的机制描述)
    • 包含公式(Formulas)章节(所有数学定义及变量说明)
    • 包含边界情况(Edge Cases)章节(异常情况已处理)
    • 包含依赖关系(Dependencies)章节(其他系统已列出)
    • 包含调优旋钮(Tuning Knobs)章节(可配置数值已识别)
    • 包含验收标准(Acceptance Criteria)章节(可测试的成功条件)
  5. 检查内部一致性

    • 公式计算出的值是否与描述的行为一致?
    • 边界情况是否与主要规则矛盾?
    • 依赖关系是否双向(对方系统是否了解本系统)?
  6. 检查可实现性

    • 规则是否足够精确,使程序员无需猜测即可实现?
    • 是否存在细节缺失的"含糊带过"章节?
    • 是否考虑了性能影响?
  7. 检查跨系统一致性

    • 是否与任何现有机制冲突?
    • 是否与其他系统产生意外的交互?
    • 是否与游戏已确立的基调和设计支柱(Pillars)一致?
  8. 按以下格式输出审查结果

## 设计审查:[文档标题]

### 完整性:[X/8 章节已存在]
[列出缺失章节]

### 一致性问题
[列出任何内部或跨系统矛盾]

### 可实现性问题
[列出任何模糊或不可实现的章节]

### 平衡性隐患
[列出任何明显的平衡风险]

### 改进建议
[按优先级排列的改进列表]

### 裁定:[通过 / 需要修订 / 需要重大修订]
  1. 上下文后续步骤建议
    • 如果被审查的文档是 game-concept.mdgame-pillars.md
      • 检查 design/gdd/systems-index.md 是否存在
      • 如果不存在,在改进建议中添加:

        "此概念已准备好进行系统分解。运行 /map-systems 将其拆解为具有依赖关系和优先级的独立系统, 然后编写各系统的 GDD。"

    • 如果文档是单个系统的 GDD:
      • 检查系统索引(Systems Index)是否引用了此系统
      • 如果裁定为通过(APPROVED):建议"将此系统在系统索引中的状态更新为'已批准'。"
      • 如果裁定为需要修订(NEEDS REVISION)或需要重大修订(MAJOR REVISION NEEDED):建议"将此系统在系统索引中的状态更新为'审查中'。"
      • 注意:此技能为只读模式。用户(或 /design-system)必须 在系统索引中执行实际的状态更新。

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.

design-review is a skill published in the GitHub repository pixel-cellar/Claude-Code-Game-Studios (326 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 911 tokens. 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 2026-08-30.
