Scaffold Exercises
Create exercise directory structures that pass `pnpm ai-hero-cli internal lint`, then commit with `git commit`.
Directory naming
- **Sections**: `XX-section-name/` inside `exercises/` (e.g., `01-retrieval-skill-building`) - **Exercises**: `XX.YY-exercise-name/` inside a section (e.g., `01.03-retrieval-with-bm25`) - Section number = `XX`, exercise number = `XX.YY` - Names are dash-case (lowercase, hyphens)
Exercise variants
Each exercise needs at least one of these subfolders: - `problem/` - student workspace with TODOs - `solution/` - reference implementation - `explainer/` - conceptual material, no TODOs When stubbing, default to `explainer/` unless the plan specifies otherwise.
Required files
Each subfolder (`problem/`, `solution/`, `explainer/`) needs a `readme.md` that: - Is **not empty** (must have real content, even a single title line works) - Has no broken links When stubbing, create a minimal readme with a title and a description: ```md
Exercise Title
Description here ``` If the subfolder has code, it also needs a `main.ts` (>1 line). But for stubs, a readme-only exercise is fine.
Workflow
1. **Parse the plan** - extract section names, exercise names, and variant types 2. **Create directories** - `mkdir -p` for each path 3. **Create stub readmes** - one `readme.md` per variant folder with a title 4. **Run lint** - `pnpm ai-hero-cli internal lint` to validate 5. **Fix any errors** - iterate until lint passes
Lint rules summary
The linter (`pnpm ai-hero-cli internal lint`) checks: - Each exercise has subfolders (`problem/`, `solution/`, `explainer/`) - At least one of `problem/`, `explainer/`, or `explainer.1/` exists - `readme.md` exists and is non-empty in the primary subfolder - No `.gitkeep` files - No `speaker-notes.md` files - No broken links in readmes - No `pnpm run exercise` commands in readmes - `main.ts` required per subfolder unless it's readme-only
Moving/renaming exercises
When renumbering or moving exercises: 1. Use `git mv` (not `mv`) to rename directories - preserves git history 2. Update the numeric prefix to maintain order 3. Re-run lint after moves Example: ```bash git mv exercises/01-retrieval/01.03-embeddings exercises/01-retrieval/01.04-embeddings ```
Example: stubbing from a plan
Given a plan like:
```
Section 05: Memory Skill Building
- 05.01 Introduction to Memory
- 05.02 Short-term Memory (explainer + problem + solution)
- 05.03 Long-term Memory
```
Create:
```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
```
Then create 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"
