Scaffold Exercises

Name: scaffold-exercises
Author: mattpocock

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:

# 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

Parse the plan - extract section names, exercise names, and variant types
Create directories - mkdir -p for each path
Create stub readmes - one readme.md per variant folder with a title
Run lint - pnpm ai-hero-cli internal lint to validate
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:

Use git mv (not mv) to rename directories - preserves git history
Update the numeric prefix to maintain order
Re-run lint after moves

Example:

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:

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"
