Apple Style PPT Maker

Overview

Drive a deterministic presentation pipeline for Apple-style minimalist decks. Enforce requirement clarification, strict schema validation, full-plan review, consistent slide rendering, selective page regeneration, and PPTX export.

Workflow

1. Check uv availability. If missing, stop and ask the user to install uv.
2. Clarify requirements with the user.
3. Build and validate slides_plan.json.
4. Get user review for the full JSON plan before image generation.
5. Generate all slide images at default 2K and webp.
6. Run result review and regenerate specific pages when requested.
7. Export slides to final.pptx.

Step 0: Verify uv

Run:

uv --version

If the command fails:

• stop the workflow immediately
• ask the user to install uv
• continue only after uv is available

Step 1: Clarify Requirements

Use a friendly, conversational tone. Do not expose internal schema field names to the user.

Ask in natural language and confirm:

• this deck's core topic
• target audience and meeting context
• expected speaking duration and target page count
• desired tone and language
• must-keep points and sensitive points to avoid

Follow user input language by default. Do not generate images before all clarification items are confirmed.

Internal mapping rule (do not show to user):

• map the confirmed answers to the internal requirement fields used by the JSON plan

Step 2: Build Structured Slide JSON

Create slides_plan.json and validate it against references/slides-schema.json. Start from references/slides-plan-template.json when you need a fast baseline.

Use references/apple-style-spec.md to keep visual consistency and style quality.

Define both content and visual intent for each page:

• text payload (on_slide_text)
• visual blueprint (visual_blueprint)
• consistency checks (consistency_checks)

Step 3: Review Full Plan Before Rendering

Always show the complete slides_plan.json to the user. Pause until the user approves the full plan. Apply edits to the JSON plan first, then render images.

Step 4: Generate Slide Images

Run:

uv run scripts/generate_slides.py --plan slides_plan.json --out outputs/deck_a

Defaults:

• resolution: 2K
• format: webp
• aspect ratio: 16:9
• model: gemini-3-pro-image-preview (Nano Banana Pro path)

Generated files:

• images/slide-XX.webp
• prompts/slide-XX.prompt.md
• meta/slide-XX.meta.json
• deck_manifest.json

Step 5: Review and Regenerate Specific Page

Run:

uv run scripts/regenerate_slide.py \
  --plan slides_plan.json \
  --slide 4 \
  --change "Simplify data narrative and increase whitespace" \
  --out outputs/deck_a

Behavior:

• Regenerate only the target slide.
• Snapshot prior image, prompt, and metadata to history/.
• Update manifest revision metadata.

Step 6: Export PPTX

Run:

uv run scripts/export_pptx.py \
  --images-dir outputs/deck_a/images \
  --output-pptx outputs/deck_a/final.pptx

Environment

Set one of:

• APPLE_STYLE_PPT_MAKER_GEMINI_API_KEY
• GEMINI_API_KEY

Optional:

• place .env in current directory
• place .env in this skill directory

Dependency management:

• each executable script uses PEP 723 inline metadata
• run scripts with uv run ... so dependencies bootstrap automatically

Notes

• Keep style and spacing consistent across all pages.
• Prefer concise, readable text over dense paragraphs.
• Use regeneration instead of re-rendering the entire deck for isolated edits.
