Gamma Presentations Skill
Generate professional presentations with expert storytelling consulting based on Duarte methodology.
⚠️ Staleness Watch (Last validated: Feb 2026 — API v0.2): Gamma is a SaaS product that ships new features and content types frequently. Check gamma.app/api for endpoint changes, new contentType values, credit pricing, and theme updates before advising on API calls.
Gamma is an AI-powered platform with 50M+ users for creating presentations, documents, social posts, and websites. This skill enables Alex to generate polished content programmatically with professional presentation consulting.
Presentation Consulting Methodology
Alex uses the Duarte methodology — the industry-leading approach used by Nancy Duarte for Apple, Al Gore, and Fortune 500 companies.
The 7 Principles of Expert Presentation Design
1. The Hero's Journey Structure
Every presentation follows story structure:
- Beginning: Establish the current state ("what is")
- Middle: Contrast with the vision ("what could be")
- End: Call to action and "new bliss" (attainable future)
2. Audience as Hero, Presenter as Mentor
- The audience is the hero facing a challenge
- The presenter (or content) is the mentor providing tools to overcome it
- Position solutions as enabling the audience's success, not showcasing the presenter
3. The Presentation Sparkline™
Alternate between "what is" and "what could be" throughout:
What is → What could be → What is → What could be → NEW BLISS
This contrast keeps audiences engaged (unlike flat reports or pure pitches).
4. S.T.A.R. Moments™
Include "Something They'll Always Remember":
- Dramatic demonstrations
- Unexpected comparisons (like Steve Jobs sliding MacBook Air into envelope)
- Emotional stories that crystallize the message
5. Data Storytelling
Transform data into meaning:
- Humanize: Make numbers relatable to individuals
- Compare: Use unexpected units of measurement
- Surprise: Lead with insight, not just charts
6. Visual Hierarchy
- One idea per slide (rule of one)
- Clear title that states the insight (not just topic)
- 5-7 bullets maximum per slide
- Use whitespace strategically
7. The New Bliss
End with a clear vision of the attainable future:
- What does success look like for the audience?
- How will their world be better?
- Concrete, achievable, inspiring
Alex Consulting Workflow
When a user provides plain text or rough content, Alex follows this consulting process:
Phase 1: Discovery
Alex analyzes the content and asks clarifying questions:
- Who is the audience? (executives, developers, investors, etc.)
- What is the goal? (inform, persuade, inspire, teach)
- What is the single most important takeaway?
- Are there emotional stories or data points to highlight?
Phase 2: Concept Presentation
Alex presents a narrative storyboard:
📊 PRESENTATION CONCEPT
Title: [Compelling title framed as benefit to audience]
Subtitle: [Supporting context]
NARRATIVE ARC:
┌─────────────────────────────────────────────────┐
│ HOOK: [Opening that establishes stakes] │
│ PROBLEM: [What is - current pain/challenge] │
│ VISION: [What could be - better future] │
│ SOLUTION: [How to get there - your offering] │
│ PROOF: [Evidence, data, stories] │
│ CALL TO ACTION: [Clear next step] │
│ NEW BLISS: [Vision of success achieved] │
└─────────────────────────────────────────────────┘
PROPOSED SLIDE STRUCTURE (10 slides):
1. Title slide with hook subtitle
2. The challenge your audience faces
3. Why this matters now
4. Section: The Vision [section divider]
5. What success looks like
6. The path forward
7. Proof point 1: [data/story]
8. Section: Taking Action [section divider]
9. Key recommendations
10. Call to action + New Bliss
S.T.A.R. MOMENT: [Proposed memorable element]
Phase 3: User Feedback
User refines the concept:
- "Add more data on slide 7"
- "Make the call to action stronger"
- "I want to emphasize X instead of Y"
Phase 4: Structured Markdown Creation
Alex generates the full structured markdown for approval:
# [Title]
## [Subtitle]
> [Speaker notes for opening]
---
# [Slide 2 Title]
- Bullet with **bold** for emphasis
- Another key point
- Third supporting point
> [Speaker notes with talking points]
---
## [Section Name] [section]
---
Phase 5: User Approval
User reviews the markdown:
- Make inline edits if needed
- Request changes to specific slides
- Approve for generation
Phase 6: Generation
Alex converts approved markdown to PPTX with:
- Alex brand colors and typography
- Proper slide layouts per the Duarte principles
- Speaker notes preserved
- Illustrations as specified
Illustrations and Visual Elements
Alex supports multiple types of illustrations in presentations.

Pro Tips for Great Results
1. Structure Your Content with Slide Markers
Use clear headers in your markdown — they become natural slide breaks:
## Slide 1: Title
Main message here
## Slide 2: The Problem
- Pain point 1
- Pain point 2
## Slide 3: Our Solution
Description of solution
2. Use Illustrations for Professional Decks
Specify --image-style with "illustrations" for consistent, modern look:
--image-model ideogram --image-style "modern clean illustrations, abstract concepts"
3. Match Tone to Audience
| Audience | Suggested Tone |
|---|
| Executives | "professional and concise" |
| Researchers | "intellectual and evidence-based" |
| Developers | "technical and practical" |
| Investors | "confident and visionary" |
| General | "friendly and accessible" |
4. One Command, Open Result
Always use --open to immediately review your deck:
node .github/muscles/gamma-generator.js -f content.md -e pptx --open
5. Iterate with Cost-Effective Models
Use cheaper models while iterating, premium for final:
--image-model flux-quick
--image-model ideogram
Cost Awareness
Alex will inform you of credit usage after each generation:
| Complexity | Estimated Credits |

Troubleshooting
Insufficient Credits
Problem: Error "insufficient credits"
Solution:
- Check balance at gamma.app/settings/billing
- Purchase credits or upgrade plan
- Enable auto-recharge
Authentication Failed
Problem: 401 Unauthorized
Solution:
- Verify API key is correct
- Check plan supports API (Pro+)
- Regenerate key if compromised
Generation Timeout
Problem: Status stays "pending" too long
Solution:
- Complex generations take longer (large numCards, premium images)
- Increase polling timeout to 2-3 minutes
- Simplify request (fewer cards, basic images)
Token Limit Exceeded
Problem: Input too large
Solution:
- inputText max: 100k tokens (~400k chars)
- Split into multiple generations
- Use
textMode: "condense" for long content
Best Practices
- Start simple - Use defaults, then customize
- Match model to need - Basic images for drafts, premium for finals
- Use appropriate textMode:
generate: Brief input → expanded contentcondense: Long input → summarized contentpreserve: Keep exact text
- Control costs - Use
flux-1-quick or imagen-3-flash for iteration
- Export wisely - Only request PPTX/PDF when needed (adds processing time)
- Organize content - Use folderIds for workspace organization

Best UX: The --open Flag
The --open flag provides seamless workflow — generate and review in one command:
node .github/muscles/gamma-generator.js \
--file content.md \
--export pptx \
--open
Two-Step Workflow: Draft → Edit → Generate
For full control over content, use the draft workflow:
Step 1: Generate a Draft Template
node .github/muscles/gamma-generator.js \
--topic "AI Ethics for Developers" \
--slides 10 \
--tone "thoughtful and practical" \
--audience "software engineers" \
--image-style "modern illustrations" \
--draft \
--open
This creates a markdown file with:
- Slide structure placeholders
- Your tone/audience settings preserved
- Image style guidance
- Opens immediately for editing
Step 2: Edit the Markdown
Fill in your actual content:
## Slide 1: Title
**AI Ethics: A Developer's Responsibility**
Building AI that serves humanity
*Illustration: Developer at computer with ethical symbols*
---
## Slide 2: Why This Matters
**The Code We Write Has Consequences**
- AI systems affect millions of lives
- Bias in training data becomes bias in decisions
- We are the last line of defense
*Illustration: Ripple effect from code to society*
Step 3: Generate from Your Edited File
node .github/muscles/gamma-generator.js \
--file ./exports/ai-ethics-for-developers-draft.md \
--image-model ideogram \
--export pptx \
--open
Why use the draft workflow?
- ✅ Full control over every slide's content
- ✅ No wasted credits on iterations
- ✅ Review structure before committing to generation
- ✅ Reuse templates for similar presentations
