balance-check

balance-check is a skill for Claude Code, Codex from pixel-cellar/Claude-Code-Game-Studios. It costs 0 tokens per session (780 once invoked), scanned A, a copy of Malicious Exfil Query, MIT.

A game-balance analysis guide for checking combat, economy, progression, and loot data, formulas, and configuration. It looks for abnormal values, broken progress curves, dominant strategies, and resource imbalances.

In plain words
What is it for?
Use it to examine game data and design documents, calculate metrics such as damage per second and time to kill, and produce a structured balance report.
Why use it?
It helps find balance problems before changed game data or designs make the player experience worse.

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

balance-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 6d 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.

Origin

This is a copy

86% identical to Malicious Exfil Query — 79 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

翻译完成,需要写入权限。以下是翻译后的完整内容:

---
name: balance-check
description: "分析游戏平衡性数据文件、公式和配置,识别异常值、破损的进度曲线、退化策略和经济失衡。在修改任何平衡相关数据或设计后使用。"

user-invocable: true
allowed-tools: Read, Glob, Grep

当此技能被调用时:

1. **识别平衡领域**(Balance Domain)——从参数中提取。

2. **读取相关数据文件**——从 `assets/data/` 和 `design/balance/` 中获取。

3. **读取设计文档**——从 `design/gdd/` 中获取被检查系统的设计文档。

4. **执行分析**:

   **战斗平衡(Combat Balance)**:
   - 计算每个威力等级(Power Tier)所有武器/技能的 DPS(每秒伤害)
   - 检查每个等级的击杀时间(Time-to-Kill)
   - 识别是否存在严格优于其他选项的选项(支配性选项)
   - 检查防御选项是否能创造无敌状态
   - 验证伤害类型/抗性交互是否平衡

   **经济平衡(Economy Balance)**:
   - 映射所有资源产出源(Faucet)和消耗点(Sink)及其流速
   - 预测资源随时间的累积情况
   - 检查是否存在无限资源循环
   - 验证金币消耗是否与金币产出同步增长
   - 检查是否有任何物品永远不值得购买

   **进度平衡(Progression Balance)**:
   - 绘制经验值(XP)曲线和战力曲线
   - 检查是否存在空白区(长时间无实质性进度)
   - 检查是否存在战力飙升(能力突然大幅跃升)
   - 验证内容门槛是否与预期玩家战力对齐
   - 检查跳过/刷怪策略是否破坏预期的节奏

   **战利品平衡(Loot Balance)**:
   - 计算获取每个稀有度等级的预期时间
   - 检查保底计时器(Pity Timer)的数学模型
   - 验证没有任何战利品在任意阶段完全无用
   - 检查背包压力与获取速率的关系

5. **输出分析报告**:

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.
