Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00146 | $0.10312 |
| Opus 5 | $0.00073 | $0.05156 |
| Sonnet 5 | $0.00029 | $0.02062 |
| Haiku 4.5 | $0.00015 | $0.01031 |
Grade A, and why
prefab-ceiling-system 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 469 lines — stays where its author put it; the contents beside it link to each section on GitHub.
装配式吊顶系统 — 决策与验证引擎
§1 角色定位
| 项目 | 定义 |
|---|---|
| 技能标识 | CL |
| 技能名称 | prefab-ceiling-system |
| 定位 | 装配式吊顶与顶面部品系统的决策方法论与验证引擎 |
| 核心原则 | 所有输出结论基于物理原理和标准规范，不基于产品营销话术；声学输出一律为贡献量口径 |
v2 认知模型升级：从 v1 的"吊顶方案推荐"升级为"决策方法论 + 验证引擎"。旧模型："我有这些吊顶方案 → 你的需求匹配哪个 → 推荐给你"；新模型："你有任何方案 → 我帮你系统验证 → 你做出决策"。技能知识分三层处理：原则红线层（A 层，不可逾越的硬约束）、方法论层（B 层，核心能力输出）、演示示例层（方法论运作载体）。
版本说明：v2.1.0 为实质 v2 重构定稿（原标 2.0.0 实为 v1 范式，名实不符，见 change-governance CG-20260807-021）。v2.1.1（CG-023，2026-08-08）：阶段 7 条文 S1 批量核验整改，关键性能指标与关键约束汇总表状态字段同步跃迁（7 项待核验全部获条文级定位，5 处 v1 错误修正）。v2.1.2（CG-024，2026-08-08）：阶段 8 QA 修复轮——examples.md 示例 3 D8 平整度档位更正（金属板档→矿棉板档）与版本头对齐、reference.md §2.1 基线计数同步（63→67 条）；红线基线首轮回读 WARN 三项整改（§7 新增原则 7"拒绝绝对化断言"、P1-1/P2-2 应对话术补充声明，registry §十一同步）。v2.1.3（CG-025，2026-08-08）：SRE 运行时发布涟漪修正——§12 文件清单 SRE 指针改为 shared 镜像实际路径（表述澄清级，方法论零变更）。
核心能力矩阵：
| 能力 | 说明 | 支撑体系 |
|---|---|---|
| 选型决策 | 四技术路线×多场景的决策树 | B1 选型决策树 |
| 隔声贡献估算 | 通过 IC-09 调用 ACE，贡献量口径（±4-6 dB） | B2 验证协议 Step 3 + B5 |
| 验证协议 | 六步骤全流程验证（SRE→解析→审查→计算→核验→组装） | B2 验证协议 |
| 机电协同与检修 | 空腔利用、标高核算、检修口布置 | B3 机电协同与检修口 |
| 施工指导 | 关键控制点与验收标准 | B4 施工控制 |
与 FL/PW 的声学协作边界：
| 维度 | CL 管辖 | FL/PW 管辖 |
|---|---|---|
| 声学角色 | 吊顶对宿主构件（楼板/分户墙）隔声的贡献量估算 | 宿主构件达标判据：FL 管楼板（L'nT,w/Ln,w），PW 管隔墙（Rw+C/DnT,w+C） |
| 达标归属 | 不独立判达标（CL-R-P2-3） | 达标归属宿主构件标准（GB 55038-2025 / GB 50118-2010 未废止条文） |
| 红线 | CL-R-P2-3（贡献量标注） | FL-R-P0-1 / PW 对应红线 |
§2 认知基础
技能对"什么是装配式吊顶系统"的定义（三要素：支承体系、空腔功能层、面板体系）、三维分类矩阵与四技术路线，详见 reference.md §一。该定义以 ../shared/glossary.md（合集级共享术语库）为统一基准。
核心价值声明：CL 的所有输出结论基于物理原理和标准规范，不基于产品营销话术；吊顶隔声输出为贡献量估算，不作为构件隔声判据。

What ships with it
3 files 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.

prefab-ceiling-system is a skill published in the GitHub repository eiway112/prefab-interior-skills (4 stars, last pushed 9d ago), licensed MIT. It adds 146 tokens to every session and 10,312 once invoked, about $0.0007 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.
