Phase 1: Collect User Input

1.1 Get Document Content

Interact with the user to obtain specific content. The format is not restricted. The user may provide the complete content, or you may generate the content for the user.

1.2 Select Style

Scan the styles/ directory, list available styles and use AskUserQuestion to choose.

1.3 Select Page Count

Use AskUserQuestion to ask:

Question: How many PPT pages would you like to generate?
Options:
- 5 pages (5-minute presentation)
- 5-10 pages (10-15 minute presentation)
- 10-15 pages (20-30 minute presentation)
- 20-25 pages (45-60 minute presentation)

1.4 Generate Video (Optional)

Question: Would you like to generate transition videos?
Options:
- Images only (Fast)
- Images + Transition videos (Full experience)

Phase 2: Document Analysis and Content Planning

2.1 Content Planning Strategy

Intelligently plan content for each page based on page count:

5-Page Version:

1. Cover: Title + Core theme
2. Point 1: First key insight
3. Point 2: Second key insight
4. Point 3: Third key insight
5. Summary: Core conclusions or action items

5-10 Page Version:

1. Cover 2-3. Introduction/Background 4-7. Core content (3-4 key points) 8-9. Case studies or data support
2. Summary and action items

10-15 Page Version:

1. Cover 2-3. Introduction/Table of contents 4-6. Chapter 1 (3 pages) 7-9. Chapter 2 (3 pages) 10-12. Chapter 3/Case studies 13-14. Data visualization
2. Summary and next steps

20-25 Page Version:

1. Cover
2. Table of contents 3-4. Introduction and background 5-8. Part 1 (4 pages) 9-12. Part 2 (4 pages) 13-16. Part 3 (4 pages) 17-19. Case studies 20-22. Data analysis and insights 23-24. Key findings and recommendations
3. Summary and acknowledgments

2.2 Generate slides_plan.json

Create JSON file and save to output directory:

{
  "title": "Document Title",
  "total_slides": 5,
  "slides": [
    {
      "slide_number": 1,
      "page_type": "cover",
      "content": "Title: AI Product Design Guide\nSubtitle: Building User-Centered Intelligent Experiences"
    },
    {
      "slide_number": 2,
      "page_type": "cover",
      "content": "User Satisfaction\nBefore use: 65%\nAfter use: 92%\nImprovement: +27%"
    },
    ...
    {
      "slide_number": n,
      "page_type": "content",
      "content": "Summary\n- User-centered approach\n- Continuous optimization\n- Data-driven decisions"
    }
  ]
}

Phase 3: Generate PPT Images

3.1 Read Style Template

Read the styles/{selected_style}.md file, generate prompts for each page, and combine complete prompts based on page_type via slide.content.

3.2 Call Nano Banana API to Generate Images

For each page, execute the following steps:

1. Send Generation Request via Image Generation Tool

2. Save Image to

   output/ppt_TIMESTAMP/images/slide-{number:02d}.png
   

3. Record each page’s prompt to prompts.json

3.4 Generate HTML Player

Read the templates/viewer.html template and replace /* IMAGE_LIST_PLACEHOLDER */ with the actual image list:

const slides = [
    'images/slide-01.png',
    // ...
];

Save as output/ppt_TIMESTAMP/index.html

Phase 4: Generate Transition Prompts (Video Mode)

If user chooses to generate videos, create transition prompts for each pair of adjacent images.

4.1 Analyze Image Differences

Read the prompt template from prompts/transition_template.md.

For each pair of adjacent images (slide-01 and slide-02, slide-02 and slide-03…), analyze:

• Visual layout differences
• Element changes
• Color transitions

4.2 Generate Transition Descriptions

Generate transition prompts based on the template, output format:

{
  "preview": {
    "slide_path": "images/slide-01.png",
    "prompt": "The frame maintains the static composition of the cover, with the central 3D glass ring slowly rotating..."
  },
  "transitions": [
    {
      "from_slide": 1,
      "to_slide": 2,
      "prompt": "The camera starts from the cover, the glass ring gradually deconstructs, splitting into transparent fragments..."
    }
  ]
}

Save to output/ppt_TIMESTAMP/transition_prompts.json

Phase 5: Generate Transition Videos (Video Mode)

5.1 Call Kling API to Generate Videos

For each transition, execute:

1. Send Generation Request via Video Generation Tool (Kling)

Request body should include:

• Start frame image (base64 or URL)
• End frame image (base64 or URL)
• Transition prompt
• Video parameters (duration 5 seconds, resolution 1920×1080)

2. Save Videos to output/ppt_TIMESTAMP/videos/

   • preview.mp4 – Home page loop preview

   • transition_01_to_02.mp4 – Transition video

5.2 Generate Video Player

Generate interactive video player based on templates/video_viewer.html template.

Phase 6: Return Results

Introduce the outputs to the user and explain how to use them.

notes for tools use

• If the invoked tool’s access is agent-pay, it means the tool is accessed by the agent on a pay-per-use basis, with no user involvement required beyond authorizing the agent to access the user’s FluxA Agent Wallet.

  Before using an agent-pay tool for the first time, inform the user and let them choose:

  To complete this task, I need to use a pay-per-use tool. Do you want to continue?
  I recommend this approach because:
  1. Lowest cost: pay per use, no expensive subscriptions.
  2. Best experience: I can access the tool autonomously. No need for you to register on the tool's website, log in, subscribe, and apply for an API key.
  

  If the user chooses ‘finding alternative solutions’, you cannot complete the task according to the skills guide and should switch to finding alternative solutions on your own.

• If the invoked tool’s access is apikey, inform the user that they need to manually configure the API key.
