# Structural Analysis
This resource supports **Step 2** of the Skill Creator workflow.
**Input files:** `$SESSION_DIR/global-context.md`, `$SESSION_DIR/step-1-output.md`, `$SOURCE_DOC` (targeted reading)
**Output files:** `$SESSION_DIR/step-2-output.md`, updates `global-context.md`
**Stage goal:** Understand what the document is about as a whole and how its parts relate.

## Why Classify Content
### WHY Content Classification Matters
Classification activates the right extraction patterns:
- **Methodologies** need sequential process extraction
- **Frameworks** need dimensional/categorical extraction
- **Tools** need template structure extraction
- **Theories** need concept-to-application mapping
**Mental model:** You read fiction differently than non-fiction. Similarly, you extract differently from processes vs. frameworks.
Without classification, you might force a framework into linear steps (loses nuance) or extract a process as disconnected concepts (loses flow).
### WHAT to Classify
#### Classification Question 1: Practical vs. Theoretical
**Practical content** teaches **how to do something** (action-focused, procedures, methods)
**Theoretical content** teaches **that something is the case** (understanding-focused, principles, explanations)
**Decide:** Is this primarily teaching **how** (practical) or **why/what** (theoretical)?
**If theoretical:** Flag this - you'll need extra synthesis in Step 4 to make it actionable.
---
#### Classification Question 2: Content Structure Type
**Sequential (Methodology/Process):**
- Look for: Numbered steps, phases, "before/after" language
- Extraction focus: Order, dependencies, decision points
**Categorical (Framework/Model):**
- Look for: Dimensions, types, categories, "aspects of" language
- Extraction focus: Categories, definitions, relationships
**Structured (Tool/Template):**
- Look for: Blanks to fill, sections to complete
- Extraction focus: Template structure, what goes where
**Hybrid:**
- Combines multiple types (e.g., Design Thinking has framework + process + tools)
- Extraction focus: Identify boundaries, extract each appropriately
---
#### Classification Question 3: Completeness Level
Rate completeness 1-5:
- **5 = Complete:** Covers when/how/what, includes examples
- **3-4 = Partial:** Missing some aspects, needs gap-filling
- **1-2 = Incomplete:** Sketchy outline, missing critical pieces
**If < 3:** Ask user if you should proceed and fill gaps or find additional sources.
---
### WHAT to Document
```markdown
## Content Classification
**Type:** [Practical / Theoretical / Hybrid]
**Structure:** [Sequential / Categorical / Structured / Hybrid]
**Completeness:** [X/5] - [Brief rationale]
**Implications:**
- [What this means for extraction approach]
- [What skill structure will likely be]
```
**Present to user for validation before proceeding.**

## Why State Unity
### WHY Unity Statement Is Critical
The unity statement is your North Star for extraction:
- Prevents scope creep (keeps focus on main theme)
- Guides component selection (only extract what relates to unity)
- Defines skill purpose (becomes core of skill description)
- Enables coherence (everything connects back to this)
**Adler's rule:** "State the unity of the whole book in a single sentence, or at most a few sentences."
Without clear unity: bloated skills, missed central points, unclear purpose.
### WHAT to Extract
Create a one-sentence (or short paragraph) unity statement:
#### Unity Formula
**For practical content:**
"This [document type] teaches how to [VERB] [OBJECT] by [METHOD] in order to [PURPOSE]."
**Example:** "This guide teaches how to conduct user interviews by asking open-ended questions following the TEDW framework in order to discover unmet needs and validate assumptions."
**For theoretical content:**
"This [document type] explains [PHENOMENON] through [FRAMEWORK] to enable [APPLICATION]."
**Example:** "This paper explains cognitive load through information processing theory to enable instructional designers to create more effective learning materials."
---
#### How to Find the Unity
**Look for:**
1. Explicit statements in abstract, introduction, or conclusion
2. "This paper/guide..." statements
3. If not explicit, infer: What question does this answer? What problem does it solve?
**Test your statement:**
- Does it cover the whole document?
- Is it specific enough to be meaningful?
- Would the author agree?
---
### WHAT to Validate
**Present to user:**
```markdown
## Unity Statement
"[Your one-sentence unity statement]"
**Rationale:** [Why this captures the main point]
Does this align with your understanding?
```
---
## Why Enumerate Parts
### WHY Structure Mapping Is Essential
Understanding how parts relate to the whole:
- Reveals organization logic (chronological, categorical, priority-based)
- Shows dependencies (which parts build on others)
- Identifies extraction units (natural boundaries for deep reading)
- Exposes gaps (missing pieces)
- Guides skill structure (major parts often become skill sections)
**Adler's rule:** "Set forth the major parts of the book, and show how these are organized into a whole."
Without structure mapping: linear reading without understanding relationships, redundant extraction, poor skill organization.
### WHAT to Extract
#### Step 1: Identify Major Parts
Look for main section headings, numbered phases, distinct topics, natural breaks.
```markdown
## Major Parts
1. [Part 1 name] - [What it covers]
2. [Part 2 name] - [What it covers]
3. [Part 3 name] - [What it covers]
```
---
#### Step 2: Understand Relationships
**Common patterns:**
**Linear:** Part 1 → Part 2 → Part 3 (sequential, each builds on previous)
**Hub-spoke:** Core concept with multiple aspects exploring different dimensions
**Layered:** Foundation → Building blocks → Advanced applications
**Modular:** Independent parts, use what you need
---
#### Step 3: Map Parts to Unity
For each part:
- How does this contribute to the overall unity?
- Is this essential or supplementary?
```markdown
## Parts → Unity Mapping
**Part 1: [Name]**
- Contribution: [How it supports main theme]
- Essentiality: [Essential / Supporting / Optional]
```
---
#### Step 4: Identify Sub-Structure
For complex documents, go one level deeper (major parts + subsections).
**Example:**
```markdown
1. Introduction
1.1. Problem statement
1.2. Proposed solution
2. Core Framework
2.1. Dimension 1
2.2. Dimension 2
2.3. How dimensions interact
3. Application Process
3.1. Step 1
3.2. Step 2
```
**Note:** Don't go too deep - 2 levels is usually sufficient.
---
### WHAT to Validate
**Present to user:**
```markdown
## Document Structure
[Your hierarchical outline]
**Organizational pattern:** [Linear/Hub-spoke/Layered/Modular]
**Key relationships:** [Major dependencies]
Does this match your understanding?
```
---
## Why Define Problems
### WHY Problem Identification Matters
Understanding the problems being solved:
- Clarifies purpose (why does this methodology exist)
- Identifies use cases (when to apply this skill)
- Reveals gaps (what problems are NOT addressed)
- Frames value (what benefit this provides)
- Guides "When to Use" section (problems = triggers)
**Adler's rule:** "Define the problem or problems the author is trying to solve."
Without problem identification: skills without clear triggers, unclear value proposition, no boundary conditions.
### WHAT to Extract
#### Level 1: Main Problem
**Question:** What is the overarching problem this document addresses?
```markdown
## Main Problem
**Problem:** [One-sentence statement]
**Why it matters:** [Significance]
**Current gaps:** [What's missing in current solutions]
```
---
#### Level 2: Sub-Problems
Map problems to structure:
```markdown
## Sub-Problems by Part
**Part 1: [Name]**
- Problem: [What this part solves]
- Solution approach: [How it solves it]
```
---
#### Level 3: Out-of-Scope Problems
What does this document NOT solve?
```markdown
## Out of Scope
This does NOT solve:
- [Problem 1 not addressed]
- [Problem 2 not addressed]
**Implication:** Users will need [OTHER SKILL] for these.
```
This defines boundaries (when NOT to use).
---
#### Level 4: Problem-Solution Mapping
```markdown
| Problem | Solution Provided | Where Addressed |
|---------|------------------|----------------|
| [Problem 1] | [Solution] | [Part/Section] |
| [Problem 2] | [Solution] | [Part/Section] |
```
This becomes the foundation for "When to Use" section.
---
### WHAT to Validate
**Present to user:**
```markdown
## Problems Being Solved
**Main problem:** [Statement]
**Sub-problems:**
1. [Problem 1] → Solved by [Part/Method]
2. [Problem 2] → Solved by [Part/Method]
**Not addressed:**
- [Out of scope items]
**Implications for "When to Use":** [Draft triggers based on problems]
Is this problem framing accurate?
```
