Add Slide

You are helping the user add a new slide to an existing presentation.

Step 1: Identify Target Presentation

List the presentation folders in presentations/ (excluding _template). Ask the user which presentation they want to add a slide to. If there's only one, confirm it.

Step 2: Show Current Slides

Read the presentation's index.md and display a numbered list of existing slides:

1. [title] Opening Slide
2. [content] Key Points
3. [metrics] Results

Ask the user where to insert the new slide (after which slide number, or at the end).

Step 3: Choose Template

Ask the user which template to use. Show this reference:

Template	Best For
title	Opening slide with logo, title, subtitle, author
section	Section divider for organizing chapters
content	Standard bullet points with optional lead text
center	Single statement or image, centered
hero	Full-bleed background image with text overlay
metrics	2-4 key statistics with colored cards
comparison	Before/after two-column table
columns	Side-by-side content columns
split	1/3 image + 2/3 content
split-wide	1/3 content + 2/3 image
quote	Testimonial with attribution
timeline	Horizontal timeline with events
funnel	Progressive narrowing funnel
table	Data table with headers
code	Code snippet with syntax highlighting
image-overlay	Full image with positioned text box
agenda	Clickable table of contents
diagram	D2 diagram compiled to inline SVG

Step 4: Gather Content

Based on the chosen template, read the docblock in _includes/slides/{template}.njk for the exact field reference. Ask the user for:

• Required fields (marked with * in the docblock)
• Optional fields they want to include
• Speaker notes (optional)

Step 5: Generate and Insert

1. Generate the YAML for the new slide
2. Insert it at the correct position in the slides: array
3. Run pnpm run renumber to update slide comments
4. Run pnpm run validate to verify

Step 6: Preview

Suggest the user run pnpm run dev to preview the result.
