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 | $0.00098 | $0.03472 |
| Opus 5 | $0.00049 | $0.01736 |
| Sonnet 5 | $0.00020 | $0.00694 |
| Haiku 4.5 | $0.00010 | $0.00347 |
Grade A, and why
acoustic-calculation-engine 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 12d 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.

ACE — 装配式装修隔声计算引擎
一、技能标识与角色定位
| 项目 | 定义 |
|---|---|
| 技能标识 | ACE |
| 技能名称 | acoustic-calculation-engine |
| 定位 | 独立补充技能——通用隔声计算基础设施 |
| 核心原则 | 底层物理模型通用化，上层评价量和构造规则由各调用方技能注入 |
| 输出性质 | 专业估算，非实验室检测值、非现场实测值 |
ACE 不直接面向终端用户。它是被隔墙（PW）、楼地面（FL）、吊顶（CL）三个领域技能调用的计算后端，通过标准化接口（IC-03/IC-08/IC-09）接收构造参数、返回估算结果和风险识别。
二、能力边界
ACE 提供以下计算能力
| 编号 | 能力 | 物理模型 | 适用场景 |
|---|---|---|---|
| C1 | 质量定律估算 | M1 | 所有板材构造的空气声隔声基础估算 |
| C2 | 吻合效应分析 | M2 | 所有薄板构造的吻合谷风险识别 |
| C3 | MSM 共振频率与空腔增益 | M3 + M4 | 双层板+空腔构造（龙骨隔墙、隔声吊顶） |
| C4 | 撞击声改善量估算 | M5 | 浮筑地面、楼面垫层 |
| C5 | 声桥/缝隙风险评估 | M6 | 所有构造的节点风险识别 |
| C6 | 敏感性分析 | M1-M6 | 关键参数变化对结果的影响趋势 |
| C7 | 基准校准估算 | M7 | 有标准图集/检测报告基准数据的同族变体构造推算（详见 §七） |
ACE 不做以下事情
- 不做"是否满足标准限值"的合规判断——该判断由调用方基于各自 A1 性能指标表完成
- 不替代实验室检测报告或现场实测——输出始终标注"专业估算"
- 不处理超出适用边界的构造——返回"超出模型适用范围"
- 不覆盖现场侧向传声、门窗薄弱构件、施工质量离散等不可建模因素
- 不包含任何标准限值，保持纯技术计算定位
- 不将基准校准结果视为变体构造的检测值——即使基准来自标准图集或检测报告，变体构造的输出仍属"专业估算"（见 §七）
三、接口契约摘要
ACE 通过三组接口契约被调用，每组契约是通用 ACE-IN/ACE-OUT 在特定场景下的实例化：
| 契约 | 调用方向 | 场景 | 评价量 |
|---|---|---|---|
| IC-03 | PW → ACE | 隔墙空气声隔声 | Rw+C / Rw+Ctr / DnT,w+C |
| IC-08 | FL → ACE | 楼地面撞击声隔声 | Ln,w / ΔL |
| IC-09 | CL → ACE | 吊顶空气声隔声 | Rw+C / Rw+Ctr |
通用输入结构（ACE-IN 三层架构）
- 调用方标识层：技能标识 + 计算类型 + 评价量
- 构造描述层：构造类型 + 板材层 + 空腔层 + 支撑/连接系统 + 密封方式
- 计算选项层：输出详细度 + 频率范围
各调用方的最小参数集详见 interface-contracts.md 对应契约。参数不足时 ACE 返回"参数不足，无法执行有效计算"并列出缺失字段。
通用输出结构（ACE-OUT）
计算结果
├─ 隔声估算区间 {下限, 上限, 评价量, 置信度}
└─ 频段分析 [{中心频率, 估算隔声量, 吻合谷标记}]
风险识别
├─ 吻合效应风险 {等级, 风险频率范围, 说明}
├─ 声桥风险等级 {等级, 风险点, 说明}
├─ 密封评估 {结论, 依据, 改进建议}
└─ 构造合理性意见 {结论, 风险点, 优化方向}
敏感性分析（标准/详细模式）
关键假设说明
适用边界声明
超出范围提示（如有）
四、红线体系
完整注册信息见 redlines-registry.md §八。以下为行为指令摘要。
P0 计算安全红线（2 条，不可违反）
| 编号 | 行为指令 |
|---|---|
| ACE-R-P0-1 | 输出只能是"专业估算"。禁止表述为实验室检测值或现场实测值。触发后立即更正并提示需检测报告确认。 |
| ACE-R-P0-2 | 输入超出模型适用范围时，禁止继续给出确定数值。返回"超出适用范围"，列出缺失信息和人工评估建议。 |
P1 计算方法红线（3 条）
| 编号 | 行为指令 |
|---|---|
| ACE-R-P1-1 | 必须识别声桥风险：龙骨刚性连接、贯通构件、节点缺陷等须纳入风险提示，输出声桥风险等级和改进建议。 |
| ACE-R-P1-2 | 必须评估密封风险：隔声密封不足会显著削弱构造性能，须输出密封评估，不得只报理论隔声量。 |
| ACE-R-P1-3 | 禁止替代主技能做合规判断：不判断是否满足标准限值，只做估算结果和风险说明。合规判断由发起方基于 A1/B2 完成。 |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 12d ago First seen · 198 lines · 98 tokens per session scan A 0074fddf985e
acoustic-calculation-engine is a skill published in the GitHub repository eiway112/prefab-interior-skills (4 stars, last pushed 10d ago), licensed MIT. It adds 98 tokens to every session and 3,472 once invoked, about $0.0005 per session on Opus 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 2026-08-31.
