# 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:

```bash
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                                                                     |

## 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)
