What it does

Write Leetcuda Book is an agent skill from xlite-dev/LeetCUDA. 把 LeetCUDA kernels/interview 教学源码（base/sgemv/sgemm/hgemm/flashattn/ffpaattn/fp8gemm.cuh/fp4gemm.cuh）+ ffpa-attn CuTe sm120 源码（csrc/cuffpa/cute fp8/fp4，commit 861d75e）写成中文 CUDA 技术书（6 Part 38 章 + CuTe 白皮书导读 + 5 附录，XeLaTeX→PDF，终态 585 页零 error）。RFC-0..N 已全部完成（2026-09-24，Part V=FP8/FP4 HGEMM 篇 ch34-37 新增，原 FP8/FP4 Attention 篇顺延为第六部分），当前任务形态 = 增补章（RFC-L/M/N 模式）/复审/勘误/图重绘。当任务涉及：撰写或修改书稿章节（chapters/chNN.tex）、每章最小测试（book/tests/chNN.cu）、ffpaattn.bench 验证、知乎资料收集与提炼、TikZ inline 图新建（主路径）与存量 drawio 图维护、源码注释核查、勾选 RFC 进度、构建/审校…

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files (for example `BOOK_PLAN.md`, `RFC.md` and `examples/drawio-recon-m1/README.md`).

It sits in Documents & Office, covering Diagrams, LaTeX and GPU and accelerator computing. It works with CUDA, draw.io, LaTeX and C++. The repository describes itself as: An Open-source book with Modern CUDA learning Notes for Beginners - BF16/FP8/FP4, HGEMM, CuTe, Flash-Attention, etc. The licence is GPL-3.0.

What it can do on your machine

Read from SKILL.md and the folder at commit c5e985f. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- python3
- pdftoppm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Write Leetcuda Book loads about 2k tokens when it runs. Until then it costs about 164 tokens; SKILL.md has 464 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~164
When it runs · the whole SKILL.md, loaded when a task matches: ~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

硬规则速查（违反必返工）

源码冻结：anchors.yaml 登记的全部源文件——各 .cuh + bench/ 下 10 个 .cu（bench/bench_leetcuda.cu 与 9 个模块 .cu：bench/{base,sgemv,sgemm,hgemm,fp8_gemm,fp4_gemm,flash_attn,ffpa_attn,utils}.cu，2026-09-29 迁入 bench/ 后均已登记）——在 RFC-A 登记 SHA256 后零改动。注释错误只记 book/CHECKLOG.md + 正文「勘误与考据」，不回写源码。
正文形态：原理讲解 + 关键代码段（每段 ≤40 行，linerange 多段裁剪，firstnumber=auto）；完整代码给附录 D 的 GitHub commit permalink；每章正文（非 listings）≥3500 字。
测试：book/tests/chNN_*.cu 无 cuBLAS/cuDNN 依赖，CPU fp64 参考 + 容差三档（F32Acc 1e-3 / F16Acc 5e-2 / TF32 1e-2），规模 ≤512，arch 不在位输出 SKIP；行数 ≤300（基础章）/≤500（复杂章）。
知乎素材：五步法（枚举→全文落 zhihu-analysis/→提炼→成文不照抄→附录 E 汇总）；图片直接引用+出处标注（作者/文章/链接/日期），原图归档 book/figures/zhihu/；水印/作者角标/平台 logo 一律标记为非内容元素，不得进入书内图。
图管线（TikZ 主路径）：新图默认 TikZ inline 写在章节 tex 内，用 tikz-diagrams skill（模板/编译渲染/视觉 QA 工具链；ch26b 六图先例，上游 5be940f 亦将存量图大规模迁为 tikzpicture）。drawio 降为存量维护路径（ch20-32 仍 36 处 png 引用）：drawio-reconstruction skill 为主（inventory→重建→审查闭环），drawio-diagram-builder/drawio-flow-forge 辅助。执行模式：主 agent 直接做，不派 task agent（闭环子代理实测易卡死，用户 2026-09-11 拍板）。审查结论如实记 audit（自审需标注）。drawio 质量三查（XML well-formed + COVER=0 + 渲染宽不越界，见「drawio 制图铁律」）；.drawio 源文件必须入库（用户要求可手改，勿只提交 PNG）。 ⚠️ TikZ 图强制视觉验收（2026-09-28 用户定为铁律）：TikZ 图出现文文重叠/图文重叠极其常见（坐标估算的文字宽度与真实渲染字宽不符所致，N.19 七图 + O.18 六图全是此类）。任何新建/修改 tikzpicture 后，必须真实渲染并 view_image 逐角落检查确认无重叠后才算完成——只看代码/编译零 error 不算验收。配方：抽图到 standalone（border=8pt + \usepackage[UTF8,fontset=fandol]{ctex}，fandol 失败则 fontset=none + \setCJKmainfont{Noto Sans CJK SC}，CJK 文本必须真实渲染、禁止用假文本代替——重叠取决于真实字宽）+ 从 book/preamble.tex 复制用到的颜色/样式定义 → xelatex -interaction=nonstopmode → pdftoppm -r 150 -png → view_image；修复优先级：平移节点/换 anchor/text width+align 换行/箭头改走线/竖排改横排（横排更宽，要挪到空白带）/字号降档（≥\scriptsize）。修法只动排版不动内容。foreach 标签里的循环变量（如 16\i）会被文本替换成数字，语义上想保留符号 i 必须改用显式值表（{0/0/16,1/16/32,...}）。
行文风格（作者基线）：参考 @DefTruth《图解:从Online-Softmax到FlashAttention V1/V2/V3》与《WINT8/4》系列——原理一定要讲细：公式逐项展开、指令逐 bit/逐字段解释、先直觉后形式化再代码；中文叙述、术语保留英文。其余可自由发挥。
注释核查五类：F1 架构事实（Prog Guide+cutlass skill arch guides）/ F2 PTX（本地 ptx-docs）/ F3 数学（独立推导）/ F4 性能断言（标来源）/ F5 历史陈述（对原论文）。
构建：CWD=book/，TEXMFCNF=../tex/: xelatex -interaction=nonstopmode book.tex ×2（或 ./build.sh）；本机已有 xelatex+ctexbook+Noto CJK（已验证）。TOC 全量装载报 main_memory capacity exceeded（PDF 目录丢失）时须 fmtutil-sys --byfmt xelatex 重建 fmt——texmf.cnf 的 main_memory 仅 fmt 生成期生效，改配置不重建无效（2026-09-22 L.9 根因）。

drawio 制图铁律（存量图维护适用；2026-09 全书返工沉淀）

生成器结构：每图一份自包含 gen.py（F 类 box/text/line + 输出 python3 gen.py <输出文件全名>，如 gen.py fig-12-2.drawio——误传目录名会产生孤儿文件）。批量期的权威源在 .tmp/drawio/gen_batch_{a,b1,b2,c1,c2,d,e}.py（.gitignore 忽略），每图目录的 gen.py 是其回流拷贝（入库、自包含）。改图必须改 .tmp 权威源再回流，直接改目录版会在下一轮批量重跑时被静默覆盖（fig-14-2 实测踩中）；回流后用 cmp -s 校验。

XML 铁律：

value 禁裸 < / &：Tile<64,64,16>、Swizzle<3,4,3>、->、R^16 类写法的 < 必须转义 <。裸 < 毁掉 well-formed → drawio 静默渲染成细条（fig-26-1 只输出 2522x74，书里等于废图）。
每个生成器末尾做 ET.fromstring(xml) 自检；全书定期 python3 -c "ET.parse" 全量扫（本次 2/39 破损）。
text 元素不自动换行：geometry 宽小于渲染宽，文字直接溢出色框（甚至越出页宽）。长注释必须手工拆多行，或把 geometry 宽改到 ≥ 估算渲染宽。
宽度估算：CJK/全角 × fontSize×1.02，ASCII × fontSize×0.58（含全角标点按 CJK 计）。check_text_fit.py 用此公式报 [OOB]（越页宽）/[COLLIDE]（侵入右邻框）。
z-order：后画的实心 box 会盖住先画的 text。右上角注释卡与左侧网格文字相交时，把文字移出卡区（check_overlap.py 的 COVER 即此类）。
导出体检：PNG 宽 ≈ pageWidth × 3（-s 3），高宽比 ≈ pageHeight/pageWidth。比例异常 = 渲染崩了（先查 XML well-formed），不要直接 includegraphics。

常见布局病（本轮回修）：说明行（y 40–60）与列头框（y 50+）净空不足 → 原点下移 16–26px；卡片内文字 409px 渲染塞 300px 框 → 框加宽 + 拆行；左表右侧的 ... 居左文本 geometry 过宽侵入相邻框 → 宽度收到渲染宽；「标题 + 图」跨页 → 图示节前 \needspace{图高+30mm}（mm = width_tw × 181 × png_h/png_w，preamble.tex 已 \usepackage{needspace}）。

其它约定：CJK 禁 bold（易糊）；两位数格宽 ≥54px；纯色缩略格无文字；.drawio/.png/gen.py 三件套全部入库。
