Gamma Presentation Generator

Generate polished presentations from a topic or content brief. Uses Gamma AI to create professionally designed slides. The user does not need a Gamma account.

When to Use

Trigger when the user wants to:

  • Create a presentation, deck, or slides
  • "Make me a pitch deck about X"
  • "Generate slides for my talk on Y"
  • "Create a presentation with 10 slides about Z"

    • Do NOT trigger for:

  • PPTX file editing (use document-skills:pptx instead)
  • HTML/web presentations (use frontend-slides instead)
  • Presenton-specific requests (use presenton instead)

    • How to Use

    Step 1: Gather Requirements

    Ask the user (if not already provided):

  • Topic or content: What the presentation is about
  • Audience: Who is this for? (investors, team, conference)
  • Length: How many slides? (default: ~8-10)
  • Format: PDF or PPTX? (default: PDF)

    • Step 2: Prepare the Input

    For best results, compose a structured prompt:

    Create a [N]-slide presentation about [TOPIC].
    Audience: [WHO]
Tone: [professional/casual/technical]
    Key points to cover:
1. [Point 1]
2. [Point 2]
3. [Point 3]
    Include: [data, charts, examples, quotes, etc.]

    Step 3: Generate

    GAMMA_API_KEY="$GAMMA_API_KEY" bun run ~/.claude/skills/gamma/generate.ts \
  --content "$(cat /tmp/gamma-prompt.txt)" \
  --format pdf \
  --output /tmp/presentation.pdf

    Or with just a topic: 

    GAMMA_API_KEY="$GAMMA_API_KEY" bun run ~/.claude/skills/gamma/generate.ts \
  --topic "IrisGo Series A Pitch" \
  --pages 12 \
  --format pdf \
  --output /tmp/pitch-deck.pdf

    Step 4: Deliver

  • If output file was saved, tell the user the file path
  • If download failed, provide the Gamma URL for manual export
  • Offer to open the file or share the link

    • Configuration

    The API key is stored in the environment. Do not expose it to the user.

    # Set in your shell profile or .env
export GAMMA_API_KEY="sk-gamma-..."

    Limitations

  • Gamma AI designs the slides — layout and visual style are Gamma's choice
  • Export to PDF/PPTX may require the Gamma URL (direct download not always available)
  • Generation takes 30-90 seconds depending on complexity
  • Content is limited by Gamma's input length (~4000 chars recommended)

    • Cost

    Each generation costs Gamma credits (~$0.01/credit, typical deck = 50-100 credits). The skill owner covers this cost — users generate for free.
