Slide Management

Slide Management

Manage slide additions and deletions with automatic renumbering. The system handles file renaming, updates slides.md, and uses git-aware operations for tracked files.

How This Skill Works

This skill provides an interactive workflow for:

• Adding slides: Insert new slide at any position with automatic renumbering of subsequent slides
• Deleting slides: Remove slide and renumber remaining slides to close gaps
• Git awareness: Uses git mv for tracked files, regular mv for untracked files

Workflow

Step 1: Find and Display Current Slides

Use Bash to find slides.md:

find . -name "slides.md" -type f -not -path "*/node_modules/*" | head -1

Then use Read tool on slides.md and parse all slide entries.

CRITICAL - Gap Detection: After parsing slides, check for gaps in slide numbering:

• Extract all slide numbers from the parsed slides
• IMPORTANT: Ignore gaps at the beginning (e.g., slide 1 then slide 5 is OK - title then content)
• Only detect gaps in the MIDDLE of the sequence (e.g., slides 5, 6, 9, 10 - gap at 7-8)
• Check from the second slide onwards

Display current presentation structure to user:

📊 Current Presentation Structure (N slides)

Position 1 → Slide 1: Title Slide
             slides/01-title.md

Position 2 → Slide 5: Introduction
             slides/05-introduction.md

Position 3 → Slide 6: Main Topic
             slides/06-main-topic.md

... (show all slides with BOTH position and slide number)

CRITICAL - Always show both:

• Position: The order in the list (1st, 2nd, 3rd...)
• Slide number: The number in the filename and comment

If gaps are detected in the middle, add a warning:

⚠️  Numbering gaps detected in middle: [7, 8]
(Note: Gap at beginning preserved - typically title at 1, content starts at 5+)
You can fix middle gaps with the renumber operation.

Important: The renumber operation:

• PRESERVES the gap between slide 1 and slide 2 (e.g., 1→5 stays as 1→5)
• FIXES gaps in the middle sequence (e.g., 5,6,9,10 becomes 5,6,7,8)
• This is by design: title slides often need separation from content slides
