PPTX Generator & Editor Overview This skill handles all PowerPoint tasks: reading/analyzing existing presentations, editing template-based decks via XML manipulation, and creating presentations from scratch using PptxGenJS. It includes a complete design system (color palettes, fonts, style recipes) and detailed guidance for every slide type.

Creating from Scratch — Workflow
Use when no template or reference presentation is available.
Step 1: Research & Requirements
Search to understand user requirements — topic, audience, purpose, tone, content depth.
Step 2: Select Color Palette & Fonts
Use the
Color Palette Reference
to select a palette matching the topic and audience. Use the
Font Reference
to choose a font pairing.
Step 3: Select Design Style
Use the
Style Recipes
to choose a visual style (Sharp, Soft, Rounded, or Pill) matching the presentation tone.
Step 4: Plan Slide Outline
Classify
every slide
as exactly one of the
5 page types
. Plan the content and layout for each slide. Ensure visual variety — do NOT repeat the same layout across slides.
Step 5: Generate Slide JS Files
Create one JS file per slide in
slides/
directory. Each file must export a synchronous
createSlide(pres, theme)
function. Follow the
Slide Output Format
and the type-specific guidance in
slide-types.md
. Generate up to 5 slides concurrently using subagents if available.
Tell each subagent:
File naming:
slides/slide-01.js
,
slides/slide-02.js
, etc.
Images go in:
slides/imgs/
Final PPTX goes in:
slides/output/
Dimensions: 10" x 5.625" (LAYOUT_16x9)
Fonts: Chinese = Microsoft YaHei, English = Arial (or approved alternative)
Colors: 6-char hex without # (e.g.
"FF0000"
)
Must use the theme object contract (see
Theme Object Contract
)
Must follow the
PptxGenJS API reference
Step 6: Compile into Final PPTX
Create
slides/compile.js
to combine all slide modules:
// slides/compile.js
const
pptxgen
=
require
(
'pptxgenjs'
)
;
const
pres
=
new
pptxgen
(
)
;
pres
.
layout
=
'LAYOUT_16x9'
;
const
theme
=
{
primary
:
"22223b"
,
// dark color for backgrounds/text
secondary
:
"4a4e69"
,
// secondary accent
accent
:
"9a8c98"
,
// highlight color
light
:
"c9ada7"
,
// light accent
bg
:
"f2e9e4"
// background color
}
;
for
(
let
i
=
1
;
i
<=
12
;
i
++
)
{
// adjust count as needed
const
num
=
String
(
i
)
.
padStart
(
2
,
'0'
)
;
const
slideModule
=
require
(
`
./slide-
${
num
}
.js
`
)
;
slideModule
.
createSlide
(
pres
,
theme
)
;
}
pres
.
writeFile
(
{
fileName
:
'./output/presentation.pptx'
}
)
;
Run with:
cd slides && node compile.js
Step 7: QA (Required)

QA Process

Theme Object Contract (MANDATORY)
The compile script passes a theme object with these
exact keys
:
Key
Purpose
Example
theme.primary
Darkest color, titles
"22223b"
theme.secondary
Dark accent, body text
"4a4e69"
theme.accent
Mid-tone accent
"9a8c98"
theme.light
Light accent
"c9ada7"
theme.bg
Background color
"f2e9e4"
NEVER use other key names
like
background
,
text
,
muted
,
darkest
,
lightest
.
Page Number Badge (REQUIRED)
All slides
except Cover Page
MUST include a page number badge in the bottom-right corner.
