# Scaffold Exercises

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 TODOs
- `solution/` — reference implementation
- `explainer/` — 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:

```md
# 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

1. **Parse the plan** — 提取 section names、exercise names 和 variant types
2. **Create directories** — 对每个 path 执行 `mkdir -p`
3. **Create stub readmes** — 每个 variant folder 一个带 title 的 `readme.md`
4. **Run lint** — 执行 `pnpm ai-hero-cli internal lint` 验证
5. **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 `.gitkeep` files
- 没有 `speaker-notes.md` files
- readmes 中没有 broken links
- readmes 中没有 `pnpm run exercise` commands
- 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:

1. 使用 `git mv`(不是 `mv`)重命名 directories,保留 git history
2. 更新 numeric prefix 以维持顺序
3. 移动后重新运行 lint

Example:

```bash
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:

```bash
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"
```
