Lean and instruction-focused with no conceptual padding; sections like 'Lint rules summary' deliver only actionable rules Claude would not already know, and every token earns its place.

Provides executable commands (`mkdir -p`, `pnpm ai-hero-cli internal lint`, `git mv`) with concrete real paths and copy-paste-ready bash examples in the stubbing walkthrough.

The Workflow is a clear 5-step sequence with an explicit validation checkpoint (Run lint → Fix any errors → iterate until lint passes), forming a proper validate-fix-retry feedback loop.

No bundle files exist and none are warranted; the body is a single-purpose skill organized into well-labeled sections (naming, variants, required files, workflow, lint rules, examples) with easy navigation and no nested references.

Lists multiple concrete actions — '创建包含章节、题目、答案和讲解的练习目录结构' (build dir structures with sections/problems/answers/explainers) and '确保通过 linting' (ensure lint passes) — rather than vague language.

Explicitly answers both what (create exercise directory structures and pass linting) and when via the '适用于用户想…时' clause, which is an explicit 'Use when' trigger.

Includes natural terms a user would say — 'scaffold exercises', '创建 exercise stubs', '设置新的课程章节' — covering the common ways this need is expressed.

Targets a clear niche — course exercise scaffolding with linting — with distinct triggers unlikely to fire for unrelated skills.
