name	deck-designer
description	Design presentation slide decks using a narrative-first pipeline. Activates on "make a deck", "create a presentation", "build slides", "design a slide deck", or any deck/slide/presentation intent.

Deck Designer

Orchestrates the full pipeline from narrative to finished slide deck.

Pipeline Overview

1. Narrative — The story as prose (use narrative-crafter if none exists)
2. NotebookLM — Generate structured slides from the narrative
3. Nano Banana Pro — Refine visuals with brand-accurate imagery
4. Creative Director — Review against brand system, iterate
5. Delivery — Final assets saved

How to Execute

1. Check for Narrative

If no narrative exists, hand off to the narrative-crafter skill first. Don't proceed without a solid narrative.

2. Determine Brand Context

Load the user's brand guide. If none exists, use the example at brand-guides/example-brand.md as a starting point and help the user customize it.

3. Generate via NotebookLM

source ~/notebooklm-env/bin/activate

# Create notebook
notebooklm create "Deck: [name]" --json

# Add narrative as source
notebooklm source add ./output/deck-[name]-narrative.md --json

# Wait for source processing
notebooklm source wait [source_id] --timeout 120

# Generate slide deck
notebooklm generate slide-deck --json

# Wait for artifact completion (can take 5-15 minutes)
notebooklm artifact wait [artifact_id] --timeout 900

# Download
notebooklm download slide-deck ./output/deck-[name]-notebooklm.pdf

4. Refine with Nano Banana Pro

Extract slides from the PDF, then refine key slides using brand-aligned prompts:

uv run [nano-banana-pro-dir]/scripts/generate_image.py \
  --prompt "[detailed slide description following brand guide]" \
  --filename "output/deck-[name]-slide-NN.png" \
  --resolution 2K \
  --aspect-ratio 16:9

For editing existing slides (refining NotebookLM output):

uv run [nano-banana-pro-dir]/scripts/generate_image.py \
  --prompt "[edit instructions referencing brand guide]" \
  --filename "output/deck-[name]-slide-NN-refined.png" \
  -i "./output/deck-[name]-notebooklm-slide-NN.png" \
  --resolution 2K

See prompts/visual-refinement-templates.md for tested prompt templates.

Rules:

• NEVER use PIL/Pillow scripts for slide generation. Only nano-banana-pro.
• Back up originals before any edits.
• Maintain style consistency across all slides.

5. Creative Director Review

Load agents/creative-director.md and review the refined slides against the brand system.

Provide:

• The generated slides
• The brand system name/guide
• Request structured feedback per slide

Iterate on any slides that don't pass review. Re-generate with nano-banana-pro using the CD's specific feedback.

6. Deliver

Save all final artifacts:

• Full deck PDF (if assembled)
• Individual slide PNGs
• Narrative document
• CD review notes

Reference Prompts

See prompts/visual-refinement-templates.md for tested templates covering:

• Title slides
• Section dividers
• Data/stat slides
• Diagram slides
• Comparison slides
• Closing/manifesto slides
