About this skill
Creates an exercise directory structure with chapters, questions, answers, and explanations, ensuring it passes linting. Use when the user wants to scaffold exercises, create exercise stubs, or set up a new course chapter.

创建能通过 pnpm ai-hero-cli internal lint 的 exercise directory structures,然后用 git commit 提交。
Directory naming
- Sections:
exercises/下的XX-section-name/(例如01-retrieval-skill-building) - Exercises:section 下的
XX.YY-exercise-name/(例如01.03-retrieval-with-bm25) - Section number =
XX,exercise number =XX.YY - Names 使用 dash-case(小写、连字符)
Exercise variants
每个 exercise 至少需要这些 subfolders 中的一个:
problem/— student workspace,包含 TODOssolution/— reference implementationexplainer/— conceptual material,不含 TODOs
创建 stub 时,除非 plan 指定其他 variant,否则默认使用 explainer/。
Required files
每个 subfolder(problem/、solution/、explainer/)都需要一个 readme.md,要求:
- 非空(必须有真实内容,即使只有一行 title 也可以)
- 没有 broken links
创建 stub 时,生成带 title 和 description 的最小 readme:
# Exercise Title
Description here
如果 subfolder 有 code,还需要 main.ts(>1 行)。但对 stubs 来说,readme-only exercise 可以接受。
Workflow
- Parse the plan — 提取 section names、exercise names 和 variant types
- Create directories — 对每个 path 执行
mkdir -p - Create stub readmes — 每个 variant folder 一个带 title 的
readme.md - Run lint — 执行
pnpm ai-hero-cli internal lint验证 - Fix any errors — 迭代直到 lint 通过
Lint rules summary
linter(pnpm ai-hero-cli internal lint)检查:
- 每个 exercise 有 subfolders(
problem/、solution/、explainer/) - 至少存在
problem/、explainer/或explainer.1/之一 - primary subfolder 中存在非空
readme.md - 没有
.gitkeepfiles - 没有
speaker-notes.mdfiles - readmes 中没有 broken links
- readmes 中没有
pnpm run exercisecommands - 除非是 readme-only,否则每个 subfolder 都需要
main.ts
Moving/renaming exercises
重新编号或移动 exercises 时:
- 使用
git mv(不是mv)重命名 directories,保留 git history - 更新 numeric prefix 以维持顺序
- 移动后重新运行 lint
Example:
git mv exercises/01-retrieval/01.03-embeddings exercises/01-retrieval/01.04-embeddings
Example: stubbing from a plan
给定这样的 plan:
Section 05: Memory Skill Building
- 05.01 Introduction to Memory
- 05.02 Short-term Memory (explainer + problem + solution)
- 05.03 Long-term Memory
创建:
mkdir -p exercises/05-memory-skill-building/05.01-introduction-to-memory/explainer
mkdir -p exercises/05-memory-skill-building/05.02-short-term-memory/{explainer,problem,solution}
mkdir -p exercises/05-memory-skill-building/05.03-long-term-memory/explainer
然后创建 readme stubs:
exercises/05-memory-skill-building/05.01-introduction-to-memory/explainer/readme.md -> "# Introduction to Memory"
exercises/05-memory-skill-building/05.02-short-term-memory/explainer/readme.md -> "# Short-term Memory"
exercises/05-memory-skill-building/05.02-short-term-memory/problem/readme.md -> "# Short-term Memory"
exercises/05-memory-skill-building/05.02-short-term-memory/solution/readme.md -> "# Short-term Memory"
exercises/05-memory-skill-building/05.03-long-term-memory/explainer/readme.md -> "# Long-term Memory"
