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 | $0.00057 | $0.01607 |
| Opus 5 | $0.00028 | $0.00804 |
| Sonnet 5 | $0.00011 | $0.00321 |
| Haiku 4.5 | $0.00006 | $0.00161 |
Grade A, and why
ppt-visual-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 today.
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.

PPT Visual Review
这是流程类 Skill，默认仅在用户显式调用 $ppt-visual-review 时运行。
对一份 PPT 式 HTML（每页一屏、固定画布）做版式验收：每一页的节奏是不是同一套。主审四件事—— 块间间隔、页边距、区域留白、并排列的对称。判定以真实渲染的图为准，测量只是线索。
本技能会直接改被审文件的版式并输出改前改后对比报告，不等用户逐条审批；文案、数字与内容结构不动。
1. 读出版面契约
先把这份 deck 的版面契约写下来，它是后面每条判定的基准：页画布尺寸、页边距、间隔档位（deck 实际在用的几个
分隔值）、卡片内边距、投影规格。契约从被审文件自身取——:root 变量、页容器的定位值、重复出现的数值——不套外部规范。
一条贯穿全篇的判定原则：同一角色的间隔，在每一页取同一个值。页眉到主区、主区到页脚、主区内相邻区块， 各是一个角色。
完成标准：页边距、区块间隔、卡片间隔三档各写出一个目标值，且每个值能在被审文件里指到出处。
2. 测量
NODE_PATH=<装了 playwright 的 node_modules> \
node scripts/measure-deck.js --file <deck.html> --out <目录> --label before --shot
产物：<label>.json（每页几何 + flags）、每页 plain 截图与 ruler 标尺图。常用开关见脚本头部注释；
页容器不是 .slide 时用 --slide-sel 指定，阈值用 --tol/--slack/--near/--min-gap 调。
脚本量的是视觉盒（含硬投影与旋转的包围盒，透明容器取子孙绘制并集），口径与理由写在脚本头部——读结果前先看那段， 否则会把「5px 投影 + 25px 间隔」误当成 30px 的间隔。
flags 是线索，不是结论：rhythm 同容器内间隔极差、cross-page 同角色跨页不一致、slack 透明区域空出的整块、
symmetry 列边错位与左右边距不对称、scale 接近但不相等的间隔档位。每条都要在第 3 步用图复核后才能进报告。
完成标准：json 覆盖全部页，pageCount 与实际页数一致；scale 归一后各页 width/height 相同。
3. 看图
逐页 Read 两张图：plain 判观感，ruler 核数值。 这一步不可跳过——数字全在容差内而看着仍不齐，以图为准；
图上看得见、flags 没报的，补成 finding。
逐页对着图问同样几件事：相邻区块的间隔是不是一个节奏；页边距四边是否对称、各页是否同值；主区底部有没有整块空出； 并排的两列底边是否对齐；同角色元素（页眉、页脚、图例、页码）在各页的位置是否落在同一条线上。
有旋转装饰、居中对齐的单行排、卡片内文字长短不一时，几像素的错位是设计意图，判为保留，不凑数量。
完成标准：每页两张图都真的看过；每条 finding 能在图上指出位置，且能说清读者会看到什么不一致。
4. 定级与改
三档定级：阻断（整块留白或列底错位，一眼就看出这页没排完）、应改（间隔不成节奏、跨页同角色不同值、 左右边距不对称）、可选（几像素的档位对齐、装饰性错位）。
改法：动档位与容器定位，不逐处补 px。把目标间隔写成变量或改页容器的边距定位，让同角色的位置在各页同源； 留白靠压缩版式空间或让容器随内容收敛来消，列底不齐靠对齐两列的收尾块。改完确认没有新增散落数值。
边界：只改版式，不动文案、数字、口径与内容结构。版式空间压不下、必须删改内容才能排满时，停下来问用户， 不要自行删内容。
完成标准：每条阻断与应改都有对应的 CSS 改动，且能说出改的是哪个档位。
5. 回归
重跑第 2 步，--label after --shot --gate，对照 before/after 的 flag 数与数值；被审仓库自带版式门禁脚本时一并跑。
完成标准：阻断与应改类 flag 清零，或每条残留都写明保留理由；after 截图逐页复看一遍，确认改动没有把内容挤出页面。
6. 报告
python3 scripts/build-report.py --data findings.json --out <报告.html>
findings.json 的字段与示例见 scripts/build-report.py 头部注释。报告是单文件 HTML，
图片内嵌，可直接转发。
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.

ppt-visual-review is a skill published in the GitHub repository hxy91819/mason-skills (2 stars, last pushed today), licensed MIT. It adds 57 tokens to every session and 1,607 once invoked, about $0.0003 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 2026-09-04.
