Creating New Documents (docx-js)

Setup

const { Document, Packer, Paragraph, TextRun, Table, TableRow, TableCell, ImageRun,
        Header, Footer, AlignmentType, PageOrientation, LevelFormat, ExternalHyperlink,
        InternalHyperlink, Bookmark, FootnoteReferenceRun, PositionalTab,
        PositionalTabAlignment, PositionalTabRelativeTo, PositionalTabLeader,
        TabStopType, TabStopPosition, Column, SectionType,
        TableOfContents, HeadingLevel, BorderStyle, WidthType, ShadingType,
        VerticalAlign, PageNumber, PageBreak } = require('docx');

const doc = new Document({ sections: [{ children: [/* content */] }] });
Packer.toBuffer(doc).then(buffer => fs.writeFileSync("doc.docx", buffer));

Validation

python scripts/office/validate.py doc.docx

Page Size

// CRITICAL: docx-js defaults to A4, not US Letter
sections: [{
  properties: {
    page: {
      size: { width: 12240, height: 15840 },  // US Letter in DXA
      margin: { top: 1440, right: 1440, bottom: 1440, left: 1440 }
    }
  },
  children: [/* content */]
}]

Common page sizes (DXA units, 1440 DXA = 1 inch):

Paper	Width	Height	Content Width (1" margins)
US Letter	12,240	15,840	9,360
A4 (default)	11,906	16,838	9,026

Landscape: Pass portrait dimensions, let docx-js swap:

size: {
  width: 12240,   // SHORT edge
  height: 15840,  // LONG edge
  orientation: PageOrientation.LANDSCAPE
},

Styles (Override Built-in Headings)

const doc = new Document({
  styles: {
    default: { document: { run: { font: "Arial", size: 24 } } },
    paragraphStyles: [
      { id: "Heading1", name: "Heading 1", basedOn: "Normal", next: "Normal", quickFormat: true,
        run: { size: 32, bold: true, font: "Arial" },
        paragraph: { spacing: { before: 240, after: 240 }, outlineLevel: 0 } },
      { id: "Heading2", name: "Heading 2", basedOn: "Normal", next: "Normal", quickFormat: true,
        run: { size: 28, bold: true, font: "Arial" },
        paragraph: { spacing: { before: 180, after: 180 }, outlineLevel: 1 } },
    ]
  },
  sections: [{
    children: [
      new Paragraph({ heading: HeadingLevel.HEADING_1, children: [new TextRun("Title")] }),
    ]
  }]
});

Lists (NEVER use unicode bullets)

// ❌ WRONG
new Paragraph({ children: [new TextRun("• Item")] })

// ✅ CORRECT
const doc = new Document({
  numbering: {
    config: [
      { reference: "bullets",
        levels: [{ level: 0, format: LevelFormat.BULLET, text: "•", alignment: AlignmentType.LEFT,
          style: { paragraph: { indent: { left: 720, hanging: 360 } } } }] },
      { reference: "numbers",
        levels: [{ level: 0, format: LevelFormat.DECIMAL, text: "%1.", alignment: AlignmentType.LEFT,
          style: { paragraph: { indent: { left: 720, hanging: 360 } } } }] },
    ]
  },
  sections: [{
    children: [
      new Paragraph({ numbering: { reference: "bullets", level: 0 },
        children: [new TextRun("Bullet item")] }),
    ]
  }]
});

Tables

// CRITICAL: Tables need dual widths - columnWidths on table AND width on each cell
const border = { style: BorderStyle.SINGLE, size: 1, color: "CCCCCC" };
const borders = { top: border, bottom: border, left: border, right: border };

new Table({
  width: { size: 9360, type: WidthType.DXA },
  columnWidths: [4680, 4680],
  rows: [
    new TableRow({
      children: [
        new TableCell({
          borders,
          width: { size: 4680, type: WidthType.DXA },
          shading: { fill: "D5E8F0", type: ShadingType.CLEAR },
          margins: { top: 80, bottom: 80, left: 120, right: 120 },
          children: [new Paragraph({ children: [new TextRun("Cell")] })]
        })
      ]
    })
  ]
})

Images

new Paragraph({
  children: [new ImageRun({
    type: "png",
    data: fs.readFileSync("image.png"),
    transformation: { width: 200, height: 150 },
    altText: { title: "Title", description: "Desc", name: "Name" }
  })]
})

Page Breaks

new Paragraph({ children: [new PageBreak()] })
new Paragraph({ pageBreakBefore: true, children: [new TextRun("New page")] })

Hyperlinks

// External
new Paragraph({
  children: [new ExternalHyperlink({
    children: [new TextRun({ text: "Click here", style: "Hyperlink" })],
    link: "https://example.com",
  })]
})

// Internal (bookmark + reference)
new Paragraph({ heading: HeadingLevel.HEADING_1, children: [
  new Bookmark({ id: "chapter1", children: [new TextRun("Chapter 1")] }),
]})
new Paragraph({ children: [new InternalHyperlink({
  children: [new TextRun({ text: "See Chapter 1", style: "Hyperlink" })],
  anchor: "chapter1",
})]})

Footnotes

const doc = new Document({
  footnotes: {
    1: { children: [new Paragraph("Source: Annual Report 2024")] },
  },
  sections: [{
    children: [new Paragraph({
      children: [
        new TextRun("Revenue grew 15%"),
        new FootnoteReferenceRun(1),
      ],
    })]
  }]
});

Tab Stops

new Paragraph({
  children: [
    new TextRun("Company Name"),
    new TextRun("\tJanuary 2025"),
  ],
  tabStops: [{ type: TabStopType.RIGHT, position: TabStopPosition.MAX }],
})

Multi-Column Layouts

sections: [{
  properties: {
    column: { count: 2, space: 720, equalWidth: true, separate: true },
  },
  children: [/* content flows naturally */]
}]

Table of Contents

new TableOfContents("Table of Contents", { hyperlink: true, headingStyleRange: "1-3" })

Headers/Footers

sections: [{
  properties: {
    page: { margin: { top: 1440, right: 1440, bottom: 1440, left: 1440 } }
  },
  headers: {
    default: new Header({ children: [new Paragraph({ children: [new TextRun("Header")] })] })
  },
  footers: {
    default: new Footer({ children: [new Paragraph({
      children: [new TextRun("Page "), new TextRun({ children: [PageNumber.CURRENT] })]
    })] })
  },
  children: [/* content */]
}]

Critical Rules for docx-js

• Set page size explicitly (default A4)
• Landscape: pass portrait dimensions
• Never use \n — use separate Paragraph elements
• Never use unicode bullets — use LevelFormat.BULLET
• PageBreak must be in Paragraph
• ImageRun requires type
• Always set table width with DXA (never PERCENTAGE)
• Tables need dual widths: columnWidths + cell width
• Always add cell margins
• Use ShadingType.CLEAR (never SOLID)
• Never use tables as dividers/rules
• TOC requires HeadingLevel only
• Override built-in styles with exact IDs: "Heading1", "Heading2"
• Include outlineLevel for TOC
• Do NOT insert internal style/theme guidance text into the document body (e.g., "Theme: ...", "layout guideline ...") unless user explicitly asks to show it as content

Editing Existing Documents

Step 1: Unpack

python scripts/office/unpack.py document.docx unpacked/

Step 2: Edit XML

• Use "Claude" as author for tracked changes
• Use Edit tool directly (not Python scripts)
• Smart quotes: ’ (apostrophe), “/” (double quotes)

Step 3: Pack

python scripts/office/pack.py unpacked/ output.docx --original document.docx

XML Reference — Tracked Changes

<!-- Insertion -->
<w:ins w:id="1" w:author="Claude" w:date="2025-01-01T00:00:00Z">
  <w:r><w:t>inserted text</w:t></w:r>
</w:ins>

<!-- Deletion -->
<w:del w:id="2" w:author="Claude" w:date="2025-01-01T00:00:00Z">
  <w:r><w:delText>deleted text</w:delText></w:r>
</w:del>

Dependencies

• pandoc, docx (npm install -g docx), LibreOffice, Poppler

PHẦN 2: PPTX — PowerPoint Skill

Path: /mnt/skills/public/pptx/SKILL.md

Quick Reference

Task	Guide
Read/analyze content	python -m markitdown presentation.pptx
Edit or create from template	Xem editing workflow
Create from scratch	Dùng PptxGenJS

Reading Content

python -m markitdown presentation.pptx
python scripts/thumbnail.py presentation.pptx
python scripts/office/unpack.py presentation.pptx unpacked/

Design Ideas — CRITICAL

Before Starting

• Pick a bold, content-informed color palette
• Dominance over equality (60-70% one color, 1-2 supporting, 1 accent)
• Dark/light contrast: Dark backgrounds for title + conclusion, light for content
• Commit to ONE visual motif and repeat it

Color Palettes

Theme	Primary	Secondary	Accent
Midnight Executive	1E2761	CADCFC	FFFFFF
Forest & Moss	2C5F2D	97BC62	F5F5F5
Coral Energy	F96167	F9E795	2F3C7E
Warm Terracotta	B85042	E7E8D1	A7BEAE
Ocean Gradient	065A82	1C7293	21295C
Charcoal Minimal	36454F	F2F2F2	212121
Teal Trust	028090	00A896	02C39A
Berry & Cream	6D2E46	A26769	ECE2D0
Sage Calm	84B59F	69A297	50808E
Cherry Bold	990011	FCF6F5	2F3C7E

For Each Slide

• Every slide needs a visual element — image, chart, icon, or shape
• Layout options: Two-column, Icon+text rows, 2x2/2x3 grid, Half-bleed image
• Data display: Large stat callouts (60-72pt), Comparison columns, Timeline/process flow

Typography

Header Font	Body Font
Georgia	Calibri
Arial Black	Arial
Cambria	Calibri
Trebuchet MS	Calibri
Palatino	Garamond

Element	Size
Slide title	36-44pt bold
Section header	20-24pt bold
Body text	14-16pt
Captions	10-12pt muted

Avoid (Common Mistakes)

• Don't repeat same layout
• Don't center body text (left-align paragraphs)
• Don't skimp on size contrast
• Don't default to blue
• Don't create text-only slides
• NEVER use accent lines under titles (AI hallmark)

PptxGenJS — Creating from Scratch

Setup

const pptxgen = require("pptxgenjs");
let pres = new pptxgen();
pres.layout = 'LAYOUT_16x9';

let slide = pres.addSlide();
slide.addText("Hello World!", { x: 0.5, y: 0.5, fontSize: 36, color: "363636" });
pres.writeFile({ fileName: "Presentation.pptx" });

Layout Dimensions

• LAYOUT_16x9: 10" × 5.625" (default)
• LAYOUT_16x10: 10" × 6.25"
• LAYOUT_4x3: 10" × 7.5"
• LAYOUT_WIDE: 13.3" × 7.5"

Text & Formatting

slide.addText("Simple Text", {
  x: 1, y: 1, w: 8, h: 2, fontSize: 24, fontFace: "Arial",
  color: "363636", bold: true, align: "center", valign: "middle"
});

// Rich text arrays
slide.addText([
  { text: "Bold ", options: { bold: true } },
  { text: "Italic ", options: { italic: true } }
], { x: 1, y: 3, w: 8, h: 1 });

// Multi-line (requires breakLine: true)
slide.addText([
  { text: "Line 1", options: { breakLine: true } },
  { text: "Line 2", options: { breakLine: true } },
  { text: "Line 3" }
], { x: 0.5, y: 0.5, w: 8, h: 2 });

Lists & Bullets

// ✅ CORRECT
slide.addText([
  { text: "First item", options: { bullet: true, breakLine: true } },
  { text: "Second item", options: { bullet: true, breakLine: true } },
  { text: "Third item", options: { bullet: true } }
], { x: 0.5, y: 0.5, w: 8, h: 3 });

// ❌ NEVER use unicode bullets

Shapes

slide.addShape(pres.shapes.RECTANGLE, {
  x: 0.5, y: 0.8, w: 1.5, h: 3.0,
  fill: { color: "FF0000" }, line: { color: "000000", width: 2 }
});

// Rounded rectangle
slide.addShape(pres.shapes.ROUNDED_RECTANGLE, {
  x: 1, y: 1, w: 3, h: 2,
  fill: { color: "FFFFFF" }, rectRadius: 0.1
});

// With shadow
slide.addShape(pres.shapes.RECTANGLE, {
  x: 1, y: 1, w: 3, h: 2,
  fill: { color: "FFFFFF" },
  shadow: { type: "outer", color: "000000", blur: 6, offset: 2, angle: 135, opacity: 0.15 }
});

Images

slide.addImage({ path: "images/chart.png", x: 1, y: 1, w: 5, h: 3 });

// With options
slide.addImage({
  path: "image.png", x: 1, y: 1, w: 5, h: 3,
  rounding: true, transparency: 50,
  sizing: { type: 'cover', w: 4, h: 3 }
});

Icons (react-icons → PNG)

const React = require("react");
const ReactDOMServer = require("react-dom/server");
const sharp = require("sharp");
const { FaCheckCircle } = require("react-icons/fa");

function renderIconSvg(IconComponent, color = "#000000", size = 256) {
  return ReactDOMServer.renderToStaticMarkup(
    React.createElement(IconComponent, { color, size: String(size) })
  );
}

async function iconToBase64Png(IconComponent, color, size = 256) {
  const svg = renderIconSvg(IconComponent, color, size);
  const pngBuffer = await sharp(Buffer.from(svg)).png().toBuffer();
  return "image/png;base64," + pngBuffer.toString("base64");
}

Charts

slide.addChart(pres.charts.BAR, [{
  name: "Sales", labels: ["Q1", "Q2", "Q3", "Q4"], values: [4500, 5500, 6200, 7100]
}], {
  x: 0.5, y: 0.6, w: 6, h: 3, barDir: 'col',
  showTitle: true, title: 'Quarterly Sales',
  chartColors: ["0D9488", "14B8A6", "5EEAD4"],
  valGridLine: { color: "E2E8F0", size: 0.5 },
  catGridLine: { style: "none" },
});

Slide Backgrounds

slide.background = { color: "F1F1F1" };
slide.background = { path: "https://example.com/bg.jpg" };
slide.background = { data: "image/png;base64,..." };

Common Pitfalls

1. NEVER use "#" with hex colors — causes corruption
2. NEVER encode opacity in hex string — use opacity property
3. Use bullet: true — NEVER unicode "•"
4. Use breakLine: true between items
5. NEVER reuse option objects (PptxGenJS mutates them)
6. Don't use ROUNDED_RECTANGLE with accent borders

Editing Existing Presentations

Workflow

1. Analyze: python scripts/thumbnail.py template.pptx
2. Plan slide mapping (USE VARIED LAYOUTS!)
3. Unpack: python scripts/office/unpack.py template.pptx unpacked/
4. Build: Delete/duplicate/reorder slides
5. Edit content in XML
6. Clean: python scripts/clean.py unpacked/
7. Pack: python scripts/office/pack.py unpacked/ output.pptx --original template.pptx

Scripts

Script	Purpose
unpack.py	Extract and pretty-print
add_slide.py	Duplicate slide or create from layout
clean.py	Remove orphaned files
pack.py	Repack with validation
thumbnail.py	Visual grid of slides

QA (Required!)

# Content QA
python -m markitdown output.pptx

# Visual QA — convert to images
python scripts/office/soffice.py --headless --convert-to pdf output.pptx
pdftoppm -jpeg -r 150 output.pdf slide

Dependencies

• pip install "markitdown[pptx]" + Pillow
• npm install -g pptxgenjs
• LibreOffice, Poppler

PHẦN 3: XLSX — Excel Spreadsheet Skill

Path: /mnt/skills/public/xlsx/SKILL.md

Requirements for All Excel Files

• Professional font (Arial, Times New Roman)
• ZERO formula errors
• Preserve existing templates

Financial Models — Color Coding

• Blue text (0,0,255): Hardcoded inputs
• Black text (0,0,0): ALL formulas
• Green text (0,128,0): Links from other worksheets
• Red text (255,0,0): External links
• Yellow background (255,255,0): Key assumptions

Number Formatting

• Years: Text strings ("2024" not "2,024")
• Currency: $#,##0, specify units in headers
• Zeros: "-" format
• Percentages: 0.0%
• Negatives: Parentheses (123) not -123

CRITICAL: Use Formulas, Not Hardcoded Values

# ❌ WRONG
total = df['Sales'].sum()
sheet['B10'] = total

# ✅ CORRECT
sheet['B10'] = '=SUM(B2:B9)'
sheet['C5'] = '=(C4-C2)/C2'
sheet['D20'] = '=AVERAGE(D2:D19)'

Common Workflow

1. Choose tool: pandas (data) or openpyxl (formulas/formatting)
2. Create/Load
3. Modify
4. Save
5. Recalculate formulas (MANDATORY):

python scripts/recalc.py output.xlsx

6. Verify and fix errors

Creating New Files

from openpyxl import Workbook
from openpyxl.styles import Font, PatternFill, Alignment

wb = Workbook()
sheet = wb.active
sheet['A1'] = 'Hello'
sheet['B2'] = '=SUM(A1:A10)'
sheet['A1'].font = Font(bold=True, color='FF0000')
sheet['A1'].fill = PatternFill('solid', start_color='FFFF00')
sheet.column_dimensions['A'].width = 20
wb.save('output.xlsx')

Reading & Analysis

import pandas as pd
df = pd.read_excel('file.xlsx')
all_sheets = pd.read_excel('file.xlsx', sheet_name=None)

Best Practices

• pandas: Data analysis, bulk operations
• openpyxl: Complex formatting, formulas
• Cell indices are 1-based
• data_only=True reads values (WARNING: saving loses formulas)
• Always recalculate with scripts/recalc.py

PHẦN 5: FRONTEND DESIGN Skill

Path: /mnt/skills/public/frontend-design/SKILL.md

Design Thinking Process

1. Purpose: What problem? Who uses it?
2. Tone: Brutally minimal, maximalist, retro-futuristic, luxury, playful, editorial, art deco, soft/pastel, industrial...
3. Constraints: Framework, performance, accessibility
4. Differentiation: What's UNFORGETTABLE?

Aesthetics Guidelines

Typography

• Choose beautiful, unique fonts — AVOID Arial, Inter, Roboto
• Pair distinctive display font with refined body font

Color & Theme

• Cohesive aesthetic with CSS variables
• Dominant colors with sharp accents
• NEVER use generic purple gradients on white

Motion

• CSS-only animations for HTML
• Motion library for React
• Staggered reveals > scattered micro-interactions

Spatial Composition

• Unexpected layouts, asymmetry, overlap, diagonal flow
• Grid-breaking elements
• Generous negative space OR controlled density

Backgrounds & Visual Details

• Gradient meshes, noise textures, geometric patterns
• Layered transparencies, dramatic shadows
• Custom cursors, grain overlays

NEVER

• Generic AI aesthetics (Inter, Roboto, Arial)
• Cliched color schemes (purple gradients)
• Predictable layouts
• Same design repeated across projects

1. Name the movement (1-2 words): "Brutalist Joy", "Chromatic Silence"
2. Articulate the philosophy (4-6 paragraphs): Space, color, scale, rhythm, hierarchy

Philosophy Examples

• "Concrete Poetry": Monumental form, bold geometry, sculptural typography
• "Chromatic Language": Color as primary information system, geometric precision
• "Analog Meditation": Texture, breathing room, Japanese photobook aesthetic
• "Organic Systems": Rounded forms, natural clustering, modular growth
• "Geometric Silence": Grid-based precision, Swiss formalism meets Brutalist

Essential Principles

• VISUAL PHILOSOPHY — aesthetic worldview
• MINIMAL TEXT — sparse, essential-only
• SPATIAL EXPRESSION — ideas through form, not paragraphs
• EXPERT CRAFTSMANSHIP — meticulously crafted, painstaking attention

Canvas Creation

• Museum/magazine quality
• Repeating patterns and perfect shapes
• Scientific diagram aesthetic
• Limited, intentional color palette
• Sophisticated, NEVER cartoony

Universal Design Principles

1. Never default to generic — pick bold, context-specific aesthetics
2. Color dominance — one color 60-70%, accents sharp
3. Typography matters — avoid Arial/Inter/Roboto for design work
4. Every slide/page needs visual elements — never text-only
5. QA is mandatory — always verify output visually
6. Formulas over hardcodes — keep spreadsheets dynamic
7. Validate everything — use validate.py/recalc.py scripts

DOCX Style Blueprint (learned from approved client docs)

Use this as default style system when creating professional DOCX plans/proposals unless user asks otherwise.

A) Typography & Hierarchy

• Body font: Calibri
• Body size: 11pt (size: 22 in docx half-points)
• Heading 1: 18pt, bold, centered on cover/title block
• Heading 2: 14pt, bold, section headers
• Notes/disclaimers: 10pt–11pt, italic, muted color

B) Color Tokens

• Primary dark (header/table head): 1A2332
• Secondary accent (section emphasis): 2D8B8B
• Text main: 1F2937
• Muted note text: 475569
• Table border: CBD5E1
• Zebra row background: F4F8FA

B.1) Alternate Client Style Pack (from reference docs)

Use when user asks for the same visual language as approved sample files.

• Heading 1 color: 2A7A78
• Heading 2 color: 8B6B4A
• Heading 3 color: 1F4D78
• Body text: 2D2D2D / 333333
• Table accents: 76C893, FF9E8A, 5B4FA0 (use sparingly)
• Header text on dark fill: FFFFFF
• Keep contrast high and avoid overusing many accent colors in one page

C) Page Layout

• Paper: US Letter (12240 x 15840 DXA) unless user requests A4
• Margins: 1080 DXA each side (≈0.75")
• Spacing: keep consistent paragraph rhythm (before/after spacing, avoid dense blocks)
• Do not use raw \n for layout; split into separate Paragraph elements

D) Tables (must-follow)

• Always use dual width strategy:
  • Table width with WidthType.DXA
  • columnWidths on table
  • width on each TableCell
• Add visible but soft borders (CBD5E1)
• Header row:
  • dark fill (1A2332)
  • white bold text
  • centered alignment
• Body rows:
  • zebra striping (FFFFFF / F4F8FA)
  • center only numeric/short fields, left-align descriptive text
• Add cell paddings/margins for readability

E) Notes & Meta Text

• Notes should be visually subordinate (italic + muted color)
• Do NOT include internal style instructions in output content (e.g., no lines like "Theme: ..." or "layout guideline ...") unless user explicitly asks

F) QA Checklist before delivery

• Header levels are visually distinct
• Table hierarchy is clear and readable on desktop/mobile view
• No orphan styling, no random colors/fonts
• No internal guideline text leaked into document body
• Output opens cleanly in Word/Google Docs/Office viewers

Execution Standard (Sprint Rollout: Active)

Use the following references for every Office task:

• Workflow policy: references/workflow-policy.md
• DOCX design system: references/design-system-docx.md
• QA checklists: references/qa-checklists.md

Mandatory operating mode:

1. Create/confirm content first.
2. Build structure second.
3. Apply design third.
4. Run QA before delivery.

If user asks for speed, still preserve the phase order with reduced depth.

Sprint Implementation Status

• Sprint 1 (workflow lock-in): Implemented
• Sprint 2 (layout/style system): Implemented
• Sprint 3 (QA framework): Implemented

Definition of done for Office output:

• Content quality passed
• Structure clarity passed
• Design consistency passed
• Technical openability passed

Brand handling:

• When brand colors are known, apply them through the design system before final styling.
• Current configured brand color preference: lime green #ABDF00 gradient-first aesthetic.
