scope-check

scope-check is a skill for Claude Code from pixel-cellar/Claude-Code-Game-Studios. It costs 47 tokens per session (902 once invoked), scanned A, original, MIT.

A scope-review tool for video-game work that compares the original plan with current implementation and identifies added or removed work. Scope creep means unplanned work expanding a project beyond its agreed plan.

In plain words
What is it for?
Use it to compare features, sprints, or milestones with the codebase and Git history, measure scope changes, assess risks, and suggest what to cut, postpone, keep, or escalate.
Why use it?
It makes schedule, quality, and integration risks visible when features or sprint tasks grow without matching cuts or extra time.

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

scope-check 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:

  1. 读取原始计划 — 找到相关文档:

    • 如果是功能名称:从 design/gdd/ 读取设计文档
    • 如果是 Sprint 编号:从 production/sprints/ 读取 Sprint 计划
    • 如果是里程碑:从 production/milestones/ 读取里程碑定义
  2. 读取当前状态 — 检查实际已实现或正在进行的部分:

    • 扫描代码库中与该功能/Sprint 相关的文件
    • 读取 Git 日志中与此工作相关的提交
    • 检查指示未完成范围新增的 TODO 注释
  3. 对比原始范围与当前范围:

    ## 范围检查: [Feature/Sprint Name]
    生成时间: [Date]
    
    ### 原始范围
    [原始计划中的项目列表]
    
    ### 当前范围
    [当前已实现或正在进行的项目列表]
    
    ### 新增范围(不在原始计划中)
    | 新增项 | 添加者 | 时间 | 有依据? | 工作量 |
    |--------|--------|------|----------|--------|
    | [item] | [commit/person] | [date] | [是/否/不明确] | [小/中/大] |
    
    ### 移除范围(在原始计划中但已取消)
    | 移除项 | 原因 | 影响 |
    |--------|------|------|
    | [item] | [移除原因] | [受影响的内容] |
    
    ### 膨胀评分
    - 原始项目数: [N]
    - 当前项目数: [N]
    - 新增项目数: [N] (+[X]%)
    - 移除项目数: [N]
    - 净范围变化: [+/-N] ([X]%)
    
    ### 风险评估
    - **进度风险**: [低/中/高] — [说明]
    - **质量风险**: [低/中/高] — [说明]
    - **集成风险**: [低/中/高] — [说明]
    
    ### 建议
    1. **裁剪**: [为按时交付应移除的项目]
    2. **延期**: [可移至未来 Sprint/版本的项目]
    3. **保留**: [确实必要的新增项]
    4. **标记**: [需要制作人(Producer)/创意总监(Creative Director)决策的项目]
    
  4. 输出范围检查结果,附带明确结论:

    • 正常: 范围在原始计划的 10% 以内
    • 轻微蔓延: 范围增加 10-25% — 通过调整可管理
    • 显著蔓延: 范围增加 25-50% — 需要裁剪或延长工期
    • 失控: 范围增加 >50% — 停止并重新规划

规则

  • 范围蔓延是指在没有相应裁剪或工期延长的情况下新增内容
  • 并非所有新增都是坏事 — 有些是发现的需求。但必须被确认并纳入考量
  • 在推荐裁剪时,优先保护核心玩家体验,而非锦上添花的功能
  • 始终量化范围变化 — "感觉变大了"不可操作,"+35% 的项目数"才是

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.
