name: chapter-evaluator description: "Evaluate educational chapters from dual student and teacher perspectives. This skill should be used when analyzing chapter quality, identifying content gaps, or planning chapter improvements. Reads all lessons in a chapter directory and provides structured analysis with ratings, gap identification, and prioritized recommendations."

Chapter Evaluator Skill

Evaluate educational chapters through dual lenses: the Student Experience (engagement, clarity, confidence) and the Teacher Perspective (pedagogy, objectives, assessment). Output structured analysis with ratings, gaps, and actionable improvements.

When to Use

• Analyzing a chapter's overall quality before publication
• Identifying why content "feels off" (too short, boring, disconnected)
• Planning improvements to existing chapters
• Comparing chapters against quality standards
• User asks to "evaluate", "review", "analyze", or "assess" a chapter

Evaluation Process

Step 1: Gather Chapter Content

Read all lesson files in the chapter directory:

ls -la <chapter-path>/*.md | grep -v summary | grep -v README | grep -v quiz

For each lesson file, extract:

• YAML frontmatter (learning objectives, cognitive load, skills, layer)
• Word count
• Section structure (headings)
• Try With AI prompts
• Hands-on exercises
• Code examples

Step 2: Student Perspective Analysis

Evaluate as a beginner encountering this content for the first time.

2.1 Engagement Score (1-10)

Score	Criteria
9-10	Compelling hook, real-world relevance clear, I want to keep reading
7-8	Interesting enough, some engaging moments, minor dry spots
5-6	Functional but forgettable, reads like documentation
3-4	Boring, walls of text, no compelling reason to continue
1-2	Would abandon after first section

Check for:

• Opening hook (does first paragraph grab attention?)
• Real-world scenarios (why does this matter to ME?)
• Story/narrative flow vs disconnected facts
• Visual breaks (diagrams, tables, code blocks)
• Pacing variety (concept → hands-on → concept)
• Comparative Value (vs alternatives like VS Code/Copilot)

2.2 Length Assessment

Verdict	Criteria
Too Short	Missing examples, concepts unexplained, abrupt endings, "I don't understand"
Just Right	Each concept has sufficient depth, examples clarify, natural flow
Too Long	Repetitive explanations, over-elaborated points, could cut 30%+

Word count benchmarks:

• Conceptual lesson: 1,000-1,400 words
• Hands-on lesson: 1,200-1,600 words
• Installation/setup: 800-1,200 words (focused)
• Capstone: 1,400-1,800 words

2.3 Clarity Score (1-10)

Score	Criteria
9-10	Crystal clear, no re-reading needed, "aha" moments
7-8	Mostly clear, occasional re-read for complex parts
5-6	Understandable with effort, some confusing sections
3-4	Frequently confused, missing context, jargon unexplained
1-2	Cannot follow, assumes knowledge I don't have

Check for:

• Jargon introduced before defined
• Logical flow between paragraphs
• Transitions between sections
• Prerequisites assumed vs stated
• Safety Checks: No concatenated commands or risky copy-pastes

2.4 Hands-On Effectiveness (1-10)

Score	Criteria
9-10	Clear steps, achievable, builds confidence, "I did it!"
7-8	Mostly clear, minor ambiguity, successful completion likely
5-6	Workable but confusing steps, may need to troubleshoot
3-4	Missing steps, unclear what to do, likely to get stuck
1-2	Cannot complete without external help

Check for:

• Step-by-step instructions (numbered, clear)
• Expected output/results shown
• Troubleshooting guidance
• Connection to concepts just learned

2.5 Progression Clarity (1-10)

Score	Criteria
9-10	Clear path from start to mastery, each lesson builds on previous
7-8	Generally progressive, minor jumps between lessons
5-6	Some logical progression, noticeable gaps
3-4	Disconnected lessons, unclear how they relate
1-2	Random ordering, no clear learning path

Check for:

• Opening connections ("In Lesson N-1, you learned X. Now...")
• Running example threaded through chapter
• Skills building on each other
• Clear "what's next" at lesson end

2.6 Confidence Score (1-10)

Score	Criteria
9-10	"I can definitely do this now" - ready to apply independently
7-8	"I mostly understand and could figure out the rest"
5-6	"I kind of get it but would need help applying it"
3-4	"I'm confused about when/how to use this"
1-2	"I have no idea what I just read"

Check for:

• Practice opportunities before moving on
• Verification steps ("you should see X")

Step 3: Teacher Perspective Analysis

Evaluate as an instructional designer assessing pedagogical soundness.

3.1 Learning Objectives Quality (1-10)

Score	Criteria
9-10	SMART objectives, measurable, aligned to content and assessment
7-8	Clear objectives, mostly measurable, good alignment
5-6	Objectives present but vague or partially aligned
3-4	Weak objectives, not measurable, poor alignment
1-2	Missing or meaningless objectives

• End-of-lesson checkpoint

Dimension Criticality & Publication Gate

CRITICAL: Not all dimensions are equally important for publication. Use this gate to determine if content is ready.

Gate Dimensions (MUST BE 7+)

These dimensions BLOCK publication if below 7/10. Fix these first.

Dimension	Why Critical	Remediation
Clarity	If unclear, nothing works. Confused students abandon.	Use technical-clarity skill
Scaffolding	Poor progression breaks learning. Students can't build on prior knowledge.	Use concept-scaffolding skill
Layer Appropriateness	Wrong layer means students lack prerequisites or are under-challenged.	Redesign layer; check prerequisites

Important Dimensions (6+)

These should be strong but minor issues are fixable.

Dimension	Target	Remediation
Engagement	6+	Add more worked examples and interactive elements
Learning Objectives	6+	Use learning-objectives skill
Assessment/Verification	6+	Add verification steps; clarity checks
Cognitive Load	6+	Reduce concepts per lesson; add practice

Enhancement Dimensions (5+)

These are nice-to-have; publication doesn't require perfection here.

• Progression Clarity (5+)
• Hands-On Effectiveness (5+)
• Confidence (5+)
• Try With AI Effectiveness (5+)

Publication Decision Logic

Use this decision tree AFTER scoring all dimensions:

IF any gate dimension (Clarity, Scaffolding, Layer) < 7:
  → REVISE: Content not ready
  → Fix the failing dimension(s)
  → Re-evaluate

ELSE IF (Engagement < 6) AND (Hands-On < 6):
  → CONDITIONAL PASS: Functional but needs improvement
  → Content is usable; improvements recommended
  → Can publish with revision plan

ELSE IF any important dimension (Objectives, Assessment, Load) < 5:
  → CONDITIONAL PASS: Missing elements but learnable
  → Flag for revision; can publish

ELSE:
  → PASS ✅: Ready for publication
  → All gate dimensions 7+
  → Most important dimensions 6+

Example Decision

Chapter Evaluation Results:

• Clarity: 8 ✅
• Scaffolding: 7 ✅
• Layer Appropriateness: 8 ✅
• Engagement: 5 (below ideal)
• Cognitive Load: 7 ✅
• Learning Objectives: 6 ✅
• Assessment: 7 ✅

Decision: PASS ✅ — All gate dimensions 7+. Engagement is low, but structure is solid. Recommend: Add more compelling examples in next revision.

Step 4: Gap Analysis

After scoring, identify specific missing elements:

Content Gaps

• Missing examples (concept taught but not demonstrated)
• Missing hands-on (theory without practice)
• Missing "why" (what but not why it matters)
• Missing troubleshooting (happy path only)
• Missing transitions (lessons don't connect)

Structural Gaps

• Missing opening hook
• Missing running example continuity
• Missing "What's Next" closure
• Missing visual elements (all text, no diagrams/tables)
• Missing code examples for technical content

Pedagogical Gaps

• Objectives not assessed
• Cognitive overload unaddressed
• Layer mismatch (content doesn't match declared layer)
• Prerequisites not actually prerequisite
• Try With AI prompts disconnected from content

Step 5: Generate Improvement Recommendations

For each gap, provide:

1. Problem: What's missing or wrong
2. Impact: How it affects learning (high/medium/low)
3. Fix: Specific action to address
4. Effort: Estimated work (low: <30min, medium: 30-90min, high: >90min)
5. Priority: 1 (critical), 2 (important), 3 (nice-to-have)
