Identify Page Structure

Analyze webpage structure using two-level hierarchy: sections, then content sequences within each section.

When to Use This Skill

Use this skill when:

•You have scraped webpage output (screenshot, HTML, metadata)
•Need to identify section boundaries and content sequences
•Ready to understand page structure before making authoring decisions

Invoked by: page-migration skill (Step 2)

Prerequisites

From scrape-webpage skill, you need:

•✅ screenshot.png showing full page
•✅ cleaned.html with page content
•✅ metadata.json with paths

Key Concepts

CRITICAL: EDS content has a strict two-level hierarchy:

code

DOCUMENT
├── SECTION (top-level container with optional metadata)
│   ├── Content Sequence 1 (default content OR block)
│   ├── Content Sequence 2 (default content OR block)
│   └── ...
├── SECTION
│   └── Content Sequence 1
└── ...

This skill analyzes BOTH levels:

•Level 1: Section boundaries (Step 2a)
•Level 2: Content sequences within EACH section (Step 2b per section)

Structure Identification Workflow

Step 2a: Identify Section Boundaries (Level 1)

Examine the screenshot to find visual/thematic breaks that indicate new sections.

Visual cues for section boundaries:

•Background color changes (white → grey → dark → white)
•Spacing/padding changes (tight → wide → normal)
•Clear horizontal breaks or dividers
•Thematic content shifts

What to exclude:

•Header/navigation (auto-populated)
•Footer (auto-populated)
•Cookie banners, popups

For each section, note:

•Section number (sequential: 1, 2, 3...)
•Visual style (light, dark, grey, accent)
•Brief overview of what's in it

Example output:

code

Section 1: light background, hero content
Section 2: light background, grid of features
Section 3: grey background, article cards
Section 4: dark background, tabs

Step 2b: Analyze Content Sequences Within Each Section (Level 2)

For EACH section identified in Step 2a, analyze its internal content sequences.

What is a "content sequence"? A vertical flow of related content that will become EITHER:

•Default content (headings, paragraphs, lists, inline images)
•A block (structured, repeating, or interactive component)

Breaking points between sequences:

•Change from default content → block
•Change from block → different block
•Change from block → default content

INVOKE page-decomposition skill FOR EACH SECTION to get neutral descriptions.

For each section, get:

•Sequence 1: [Neutral description - NO block names yet]
•Sequence 2: [Neutral description]
•...

Example output:

code

Section 1 (light):
  - Sequence 1: Large centered heading, paragraph, two buttons
  - Sequence 2: Two images displayed side-by-side

Section 2 (light):
  - Sequence 1: Centered heading
  - Sequence 2: Grid of 8 items, each with icon and short text
  - Sequence 3: Two centered buttons

Section 3 (grey):
  - Sequence 1: Eyebrow text, heading, paragraph, button
  - Sequence 2: Four items in grid, each with image, category tag, heading, description

Section 4 (dark):
  - Sequence 1: Tab navigation with three switchable content panels

Step 2.5: Survey Available Blocks

STOP: Before making any authoring decisions, understand what blocks are available.

INVOKE block-inventory skill to catalog available blocks.

Why this matters: Real authors see a block library and choose from available options. You need the same context to make authentic authoring decisions following David's Model.

What this provides:

•Local blocks already in project
•Common Block Collection blocks that can be added
•Purpose/description for each block
•Live example URLs

Example output:

code

Available Blocks:

LOCAL BLOCKS:
- custom-banner: Special promotional banner
- testimonial-slider: Customer testimonials carousel

BLOCK COLLECTION AVAILABLE:
- hero: Large heading, text, buttons for page intro
- cards: Grid of items with images/text
- columns: Side-by-side content layout
- accordion: Expandable Q&A sections
- tabs: Switchable content panels
- carousel: Rotating image/content displays
- quote: Highlighted testimonials
- fragment: Reusable content sections

Output Format

This skill provides complete page structure:

1. Section boundaries with styling:

code

Section 1: light background
Section 2: light background
Section 3: grey background (#f5f5f5)
Section 4: dark background (#1a1a1a)

2. Content sequences per section (neutral descriptions):

code

Section 1 (light):
  - Sequence 1: Large centered heading, paragraph, two call-to-action buttons
  - Sequence 2: Two images displayed side-by-side

Section 2 (light):
  - Sequence 1: Single centered heading
  - Sequence 2: Grid of 8 items, each with icon and short text
  - Sequence 3: Two centered buttons

[Continue for all sections...]

3. Block palette:

code

LOCAL BLOCKS: [list]
BLOCK COLLECTION AVAILABLE: [list with purposes]

Next step: Pass these outputs to authoring-analysis skill

Key Principles

Two-level analysis is mandatory:

•You MUST identify sections first (2a)
•Then analyze each section's content sequences (2b)
•Don't skip levels or combine them

Stay neutral at this stage:

•Describe WHAT you see, not WHAT it should be
•"Grid of items with images" not "Cards block"
•Authoring decisions come in next skill

Block inventory before decisions:

•Survey blocks BEFORE making any authoring choices
•Authors see a library and choose - you need same context
