Yachiyo PPTX

Use this skill when the user wants to inspect, update, or create a presentation.

Read guide.md for the full workflow. Use the inspector script before editing an existing deck:

python3 resources/core-skills/yachiyo-pptx/scripts/pptx_inspect.py path/to/file.pptx --json

Workflow

1. Identify the task:
   • Extract slide text or notes
   • Update an existing deck
   • Create a new deck
   • Reorder, split, or combine slides
   • Replace text, charts, or images
2. Choose the narrowest tool that fits.
3. Save to a new file by default.
4. Verify the result before reporting back.

Tool Selection

• slide text extraction tools: reading content quickly
• PPTX unzip plus XML inspection: precise debugging or structured edits
• a presentation generation library: creating or rewriting decks programmatically
• PDF or image export: visual verification when layout matters

Editing Rules

• Preserve the existing template, theme, and layout unless the user asked for redesign.
• Change only the slides that need to change.
• If slide visuals matter, do not rely on text extraction alone.
• When creating a new deck, keep the structure intentional and concise rather than filling slides with generic bullets.

Output Rules

• Do not overwrite the source .pptx unless the user explicitly asks for it.
• Use explicit filenames such as updated-deck.pptx or summary-deck.pptx.
• If a conversion or regeneration may alter layout fidelity, state that before doing it.

Verification

Before finishing:

• Confirm the output file exists.
• Confirm the expected slide count.
• Re-check changed slide text, titles, and notes.
• If layout matters, export a visual preview and spot-check the changed slides.
