PPT Generator Skill#

Professional presentation engine. Generates SVG pages and converts them to native editable PPTX via svg_to_pptx. Includes 8 layout templates covering dark, light, consulting, tech, and more.

When to Use#

• User asks to create a PPT / presentation / slides
• User provides content, outline, or data that needs to become a PPTX
• User mentions "make a PPT", "generate slides", "presentation", etc.

Interaction Flow (must follow)#

After receiving a PPT request, do not generate immediately. Guide the user step by step:

Step 1: Confirm Topic and Duration#

Got it, I'll make this PPT for you. Topic: "{extracted from user message}" — correct? How long is the presentation? This determines page count:

• 10 min → 10-12 pages
• 20 min → 15-18 pages
• 30 min → 22-25 pages
• 45 min → 28-35 pages

Duration is required — do not skip this. Page count directly depends on it.

If the user already provided a detailed outline, skip topic confirmation but still ask duration.

Step 2: Pick a Style#

Pick a style (just reply with the number):

1. dark_warm (default) — dark warm tone, AI/tech feel

2. consultant — white + blue, consulting style

3. cloud_orange — deep navy + orange, cloud/tech architecture

4. ai_ops — full dark, ops/DevOps style

5. tech_blue — blue tech, formal business

6. smart_red — red business

7. exhibit — light showcase, data-heavy

8. pixel_retro — pixel retro, creative/fun

Step 3: Confirm Outline#

Propose a structure based on the topic and style:

Based on your needs, here's a suggested structure ({N} pages):

P1 — Cover: {title}

P2 — Table of Contents

P3 — {Section 1 title}

...

P{N} — Closing: {key takeaway / CTA}

Want to adjust anything, or shall I start generating?

Step 4: Generate#

Only start after user confirms. Send a status message:

Starting generation, estimated X minutes.

Then execute the Technical Flow below.

Step 5: Deliver and Iterate#

Send the final PPTX with a brief note:

PPT is ready, {N} pages total. Want changes? Just say:

• "Update the data on page 3"
• "Add a page about XX"
• "Make the colors darker"

Technical Flow (executed in Step 4)#

text

Read design_spec.md + reference SVGs → Write SVG files → svg_to_pptx → Deliver

Phase 1: Read Design Spec#

Load the target style's design spec and reference templates:

text

ppt-master-assets/templates/layouts/{style}/design_spec.md   ← colors, fonts, layout rules
ppt-master-assets/templates/layouts/{style}/01_cover.svg      ← cover reference
ppt-master-assets/templates/layouts/{style}/02_chapter.svg    ← chapter page reference
ppt-master-assets/templates/layouts/{style}/03_content.svg    ← content page reference
ppt-master-assets/templates/layouts/{style}/04_ending.svg     ← ending page reference

Phase 2: Generate SVG Files#

Use the write tool to create SVG files page by page in /tmp/ppt_svgs/{style}/.

SVG Rules:

1. viewBox must be 0 0 1280 720 (16:9)
2. Strictly follow design_spec.md for colors, fonts, and layout
3. Do not use: foreignObject, clipPath, mask, <style>, class
4. File naming: 01_cover.svg, 02_toc.svg, 03_chapter1.svg... in order
5. All text uses <text> elements with font-family, font-size, fill
6. Background: full-coverage <rect>. Decorations: <rect>/ <circle>/ <line>/ <path>
7. Tables: manual <rect> + <text> layout (no HTML tables)
8. Fill the page — avoid large empty areas
9. Titles should state insights, not category labels

Suggested order:

• Cover and ending first (set the tone)
• Chapter dividers next (consistent style)
• Content pages last (data-heavy, one at a time)

Phase 3: SVG → PPTX Conversion#

svg_to_pptx converts SVG elements into native DrawingML shapes (not images):

• <text> → editable text boxes (double-click to edit)
• <rect> → native rectangles (drag, recolor)
• <circle> / <ellipse> → native circles
• <line> / <path> → native lines/paths
• Tables (rect + text combos) → editable shape groups

The output PPTX is fully editable in PowerPoint, just like a manually created file.

python

import sys, os
sys.path.insert(0, os.path.expanduser(
    "~/.openclaw/workspace/skills/ppt-generator/ppt-master-assets/scripts"))
from svg_to_pptx import create_pptx_with_native_svg
from pathlib import Path

svgs = sorted(Path("/tmp/ppt_svgs/{style}").glob("*.svg"))
create_pptx_with_native_svg(svgs, Path("/tmp/output.pptx"),
                            canvas_format="ppt169",
                            use_native_shapes=True,  # required! otherwise SVG is embedded as image
                            verbose=True)

Phase 4: Cross Review (optional, requires user confirmation)#

After generating the first draft, ask the user:

First draft is ready. Want to run a cross-review? Multiple reviewers check in parallel — more thorough but takes a few minutes.

If the user agrees and the agent supports subagents, run a review-fix cycle:

1. Round 1 (full review): Launch 5 reviewer subagents in parallel

   • 🎤 Presentation Coach — narrative arc, flow, pacing
   • 👥 Target Audience — simulated audience reaction, comprehension
   • 🔬 Domain Expert — factual accuracy, technical depth
   • 📋 Content Auditor — structure, typos, data consistency
   • 👁️ Visual Inspector — layout, alignment, readability

2. Fix: Aggregate all issues, fix by priority (🔴 before ⚠️)

3. Round 2 (regression): 3 reviewers verify the fixes

4. Exit criteria: 🔴=0 and ⚠️≤3, or round≥4 force exit

Skip if user says "no review" or "just a quick draft".

Phase 5: Deliver#

Only send the final version. Do not send intermediate versions unless the user asks.
