What problem does it solve? Setting up course exercise structures manually is error-prone: wrong naming conventions, missing readme files, and lint failures from pnpm ai-hero-cli internal lint waste time. This Skill scaffolds exercise directories that pass linting on the first run. ## Core Features & Use Cases - Directory Scaffolding: Creates section folders (XX-section-name/) and exercise folders (XX.YY-exercise-name/) with correct dash-case naming and numeric ordering. - Variant Support: Generates problem/, solution/, and explainer/ subfolders, each with a non-empty readme.md stub that satisfies lint rules. - Lint Validation & Fixes: Runs pnpm ai-hero-cli internal lint and iterates on errors until the structure passes, then commits with git. - Use Case: Given a course plan listing sections and exercises, scaffold the entire exercises/ tree with stub readmes, validate it with the linter, and commit the result in one workflow. ## Quick Start Scaffold the exercises from my course plan into the exercises directory and make sure they pass lint.
