What problem does it solve? Manually creating course exercise folders that satisfy strict linting rules is error-prone and repetitive. This Skill scaffolds section and exercise directories with the correct naming, subfolders, and readme stubs so they pass pnpm ai-hero-cli internal lint on the first run. ## Core Features & Use Cases - Directory Scaffolding: Creates numbered section folders (XX-section-name) and exercise folders (XX.YY-exercise-name) with dash-case naming. - Variant Support: Generates problem/, solution/, and explainer/ subfolders, each with a non-empty readme.md stub. - Lint Validation: Runs pnpm ai-hero-cli internal lint and iterates on errors until the structure passes. - Safe Renaming: Uses git mv to renumber or move exercises while preserving git history. - 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. ## Quick Start Scaffold the exercises from my course plan into the exercises directory and make sure they pass linting.
