PPT Generator Pro

Use this skill to create image-first PPT presentations and optional transition videos from a document, outline, or pasted text.

Quick Start

1. Read the user's source content from a file path or pasted text.
2. Before choosing style or layout, ask the user whether to output using the company PPT template when the request is to create a PPT/deck:
   • Template asset: assets/company-template/company-ppt-template.ppt
   • Original source: /Users/hanyueyang/Desktop/公司PPT template.ppt
   • If the user says yes, preserve the company's visual identity, layout conventions, typography, colors, footer/header patterns, and page hierarchy as much as the generation workflow allows.
   • Also mention the reusable template library if the user wants a non-company PPT style:
     • assets/template-library/business-blue-green-yellow-minimal.pptx
     • assets/template-library/red-navy-visual-tables.pptx
3. Choose a style from styles/ or assets/template-library/ if the company template is not requested or if extra image-style guidance is needed:
   • gradient-glass.md: technology/business, gradient glass cards.
   • vector-illustration.md: warmer educational or explanatory visuals.
4. Decide page count, language, and whether video transitions are needed.
5. Ensure required environment variables are present:
   • GEMINI_API_KEY for slide image generation.
   • KLING_ACCESS_KEY and KLING_SECRET_KEY only for Kling video features.
6. Run the appropriate script from this skill directory:
   • generate_ppt.py for slide images and interactive viewer.
   • generate_ppt_video.py for slides plus transition videos.

Read references/upstream-skill.md for the full upstream workflow and parameter details.

Workflow

1. Analyze the content.

   • Extract core message, target audience, structure, and visual story.
   • Convert long documents into a page-by-page outline before generating images.

2. Generate slide prompts.

   • Keep each slide focused on one message.
   • Use style files in styles/ to keep visual consistency.
   • For dense professional content, favor structured cards, diagrams, timelines, matrices, and clear hierarchy.

3. Generate assets.

   • Use the repository scripts rather than rewriting the full generation pipeline.
   • Keep outputs in a project-specific folder.
   • Preserve generated prompts and image/video metadata for later editing.

4. Review quality.

   • Check that slide text is readable, not hallucinated, and matches source content.
   • Check 16:9 framing, consistent style, page order, and visual continuity.
   • For video output, verify transitions, resolution, frame rate, and audio/video duration if applicable.

Important Files

• assets/company-template/company-ppt-template.ppt: company PPT template. Ask whether to use it before making PPTs.
• assets/template-library/README.md: reusable PPT template index.

• assets/template-library/red-navy-visual-tables.pptx: red + dark navy visual table template.
• generate_ppt.py: main slide image generation flow.
• generate_ppt_video.py: slide plus transition-video flow.
• kling_api.py: Kling AI API helper.
• transition_prompt_generator.py: transition prompt generation.
• video_composer.py: video composition helper.
• templates/viewer.html: interactive slide viewer.
• templates/video_viewer.html: interactive video/image viewer.
• styles/: visual style prompts.
• prompts/transition_template.md: transition prompt template.

Quality Rules

• Do not invent technical facts, citations, regulatory claims, or clinical claims when turning source documents into slides.
• For client or regulated content, preserve the user's meaning and mark any uncertain interpretation.
• Keep slide text concise; move dense detail into speaker notes or an appendix if needed.
• Verify generated files exist before reporting completion.
• If API keys or FFmpeg are missing, explain the missing prerequisite and provide the next command or configuration needed.
