What it does

Deck Generator is an agent skill from ericosiu/ai-marketing-skills. Generate professional presentations with AI-generated images. Use when asked to create a deck, presentation, pitch deck, or slides. Supports style presets (whiteboard, corporate, minimalist, etc). Uses Imagen 4.0 API for image generation and Google Slides API for assembly. Produces full decks from markdown content specs in minutes.

Its SKILL.md is about 910 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `README.md` and `scripts/generate-deck.py`).

It sits in Documents & Office, covering Slides and decks and Cloud office suites. It works with Google Slides. The repository describes itself as: Open-source AI marketing skills — growth experiments, sales pipeline, content ops, outbound, SEO, and finance automation. The licence is MIT.

Requirements

A credential in GEMINI_API_KEY

Workflow steps

4 steps, taken from the step headings in SKILL.md.

Review & Iterate

What it can do on your machine

Read from SKILL.md and the folder at commit 8088e1a. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- GEMINI_API_KEY
- GOOGLE_APPLICATION_CREDENTIALS
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Deck Generator loads about 909 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 296 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~87
When it runs · the whole SKILL.md, loaded when a task matches: ~909

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

name: deck-generator
description: Generate professional presentations with AI-generated images. Use when asked to create a deck, presentation, pitch deck, or slides. Supports style presets (whiteboard, corporate, minimalist, etc). Uses Imagen 4.0 API for image generation and Google Slides API for assembly. Produces full decks from markdown content specs in minutes.

Deck Generator

Generate complete presentations where every slide is an AI-generated image in a consistent visual style.

Quick Start

Read the content spec (user provides slide content or a markdown file)
Read references/styles.md to pick or customize a visual style
Run scripts/generate-deck.py with content + style

Workflow

Step 1: Content Spec

Accept slide content in any format. Normalize to this structure per slide:

Title: Bold headline
Body: Key points, stats, or narrative
Visual cues: Icons, diagrams, layouts described in words

If user provides a markdown file with --- separators, parse each section as a slide. If user provides a topic only, generate 10-14 slides following standard deck structures.

Step 2: Style Selection

Available style presets:

Style	Description
`whiteboard`	Hand-drawn sketch on white. Black ink, orange accents.
`corporate`	Navy/white/gold. Clean sans-serif. Professional.
`minimalist`	Pure white, electric blue accent. Maximum negative space.
`dark-tech`	Near-black background, neon green. Terminal aesthetic.
`playful`	Bright pastels, rounded shapes. Modern startup vibe.
`editorial`	Black/white with red spot color. Magazine aesthetic.

Default: whiteboard. User can specify any preset or describe a custom style.

Step 3: Generate

bash

# Set your API key
export GEMINI_API_KEY="your-gemini-api-key"

# Run the generator
python3 scripts/generate-deck.py \
  --content slides.json \
  --style whiteboard \
  --title "Deck Title" \
  [--output-dir ./output] \
  [--aspect 16:9]

The script:

Generates each slide image via Imagen 4.0 API
Saves all images to the output directory
Optionally creates a Google Slides presentation (requires Google Slides API credentials)
Returns paths to all generated images

Step 4: Review & Iterate

To regenerate individual slides:

bash

python3 scripts/generate-deck.py \
  --content slides.json \
  --style whiteboard \
  --slides 3,7 \
  --output-dir ./output

Key Details

Cost: ~4 cents per image. A 14-slide deck costs roughly 56 cents in API calls.
Speed: ~2 minutes for 14 slides.
API: Imagen 4.0 via Google's Generative Language API
Auth: Set $GEMINI_API_KEY environment variable
Aspect ratios: 16:9 (default), 1:1, 4:3, 3:4, 9:16
Image models: imagen-4.0-generate-001 (best quality), imagen-4.0-fast-generate-001 (faster)

Content JSON Format

[
  {"name": "01-title", "prompt": "Title slide: 'Your Deck Title' with company logo placeholder"},
  {"name": "02-problem", "prompt": "Problem slide showing frustrated marketer staring at dashboard with declining metrics"},
