Presentation Structure Skill

Knowledge about how the presentation at presentation/index.html is structured.

File Location

presentation/index.html — a single-file HTML presentation with inline CSS and JS.

Slide Format

Each slide is a div with data-slide (sequential number) and optional data-level (journey level at transition points):

<!-- Regular slide — inherits level from previous data-level slide -->
<div class="slide" data-slide="12">
    <h1>Slide Title</h1>
    <!-- content -->
</div>

<!-- Level transition slide — sets new level for this slide and all following -->
<div class="slide section-slide" data-slide="10" data-level="low">
    <h1>Section Name</h1>
    <p class="section-desc">Level: Low — description of this section</p>
</div>

<!-- Title slide (centered) -->
<div class="slide title-slide" data-slide="1">
    <h1>Presentation Title</h1>
    <p class="subtitle">Subtitle text</p>
</div>

Journey Bar Level System

The presentation uses a 4-level system instead of cumulative percentages:

• Levels are set via data-level attribute on key transition slides (section dividers)
• All slides after a data-level slide inherit that level until the next transition
• The journey bar fills to 25% / 50% / 75% / 100% for Low / Medium / High / Pro respectively
• The bar is hidden on slide 1 (title slide); from slide 2 onward the bar is shown
• Slides before the first data-level (slides 2–9) show an empty bar (no level yet set)
• A .level-badge is JS-injected on the <h1> of slides that carry data-level — do NOT hardcode in HTML

Level Transitions by Section

| Section | Slide Range | data-level | Bar Height | |---------|-------------|------------|------------| | Part 0: Introduction | Slides 1-4 | (none) | hidden / empty | | Part 1: Prerequisites | Slides 5-9 | (none) | empty | | Part 2: Better Prompting | Slides 10-17 | low | 25% | | Part 3: Project Memory | Slides 18-24 | medium | 50% | | Part 4: Structured Workflows | Slides 25-28 | (inherits medium) | 50% | | Part 5: Domain Knowledge | Slides 29-33 | high | 75% | | Part 6: Agentic Engineering | Slides 34-46 | high | 75% | | Appendix | Slides 47+ | (inherits high) | 75% |

Navigation System

• goToSlide(n) — used in TOC links, must match actual data-slide numbers
• totalSlides is auto-computed from DOM (document.querySelectorAll('[data-slide]').length)
• Arrow keys, Space, and touch swipe for navigation
• Slide counter shows current / total at bottom-left

Renumbering Rules

After adding, removing, or reordering slides:

1. Renumber ALL data-slide attributes sequentially starting from 1
2. Update all goToSlide() calls in the TOC/Journey Map slide
3. The JS totalSlides auto-computes — no manual update needed
4. Verify no gaps or duplicates exist

Section Divider Format

Section dividers use the section-slide class. Level-transition section dividers carry data-level and show the level name in the description:

<div class="slide section-slide" data-slide="10" data-level="low">
    <p class="section-number">Part 2</p>
    <h1>Better Prompting</h1>
    <p class="section-desc">Level: Low — effective prompting for real results.</p>
</div>

The JS will inject a .level-badge (e.g., "→ Low") into the <h1> at runtime when the level transitions — do not add these manually in HTML.
