name: document-quality-standards description: Use when creating or editing documents (DOCX, PDF, XLSX, PPTX) that need professional output. Adds visual verification, typography hygiene, and formula patterns.

Document Quality Standards

Patterns that complement the official document-skills plugin. Apply these alongside xlsx, pdf, docx, and pptx skills.

Visual-First Verification

Core principle: Text extraction misses critical details. Always verify visually.

"Only do python printing as a last resort because you will miss important details with text extraction (e.g. figures, tables, diagrams)."

The Render-Inspect-Fix Loop

For ANY document operation (create, edit, convert):

Copy1. Generate/modify document
2. Convert to PNG:
   pdftoppm -png -r 150 document.pdf output
3. Visually inspect the PNG at 100% zoom
4. Fix any issues found
5. REPEAT until clean

Never deliver a document without PNG verification. This catches:

• Clipped or overlapping text
• Broken tables
• Missing figures
• Formatting inconsistencies
• Orphans/widows
• Unreadable characters

Quick Conversion Commands

Copy# DOCX → PDF → PNG
soffice --headless --convert-to pdf document.docx
pdftoppm -png -r 150 document.pdf page

# PDF → PNG directly
pdftoppm -png -r 150 document.pdf page

# PPTX → PDF → PNG
soffice --headless --convert-to pdf presentation.pptx
pdftoppm -png -r 150 presentation.pdf slide

Typography Hygiene

Hyphen Safety

Never use non-breaking hyphens (U+2011). They cause rendering failures in many viewers.

Copy# WRONG - may render as boxes or break layouts
text = "co‑author"  # U+2011 non-breaking hyphen

# CORRECT - always use ASCII hyphen
text = "co-author"  # U+002D standard hyphen-minus

Detection and fix:

Copy# Find problematic hyphens
import re
if '\u2011' in text:
    text = text.replace('\u2011', '-')

# Also watch for other non-ASCII dashes
text = text.replace('\u2013', '-')  # en-dash
text = text.replace('\u2014', '-')  # em-dash (if hyphen intended)

Citation Format

All citations must be human-readable in standard scholarly format:

• No internal tool tokens (e.g., 【4:2†source】)
• No malformed references
• Include: Author, Title, Source, Date, URL (if applicable)

Copy# WRONG
See source 【4:2†source】 for details.

# CORRECT
See Smith (2024), "Document Standards," Journal of Tech, p. 45.

Spreadsheet Formula Patterns

Complements the xlsx skill's color conventions with additional patterns.

Extended Color Codes

Beyond the standard 5 colors (blue inputs, black formulas, green cross-sheet, red external, yellow assumptions):

Formula Simplicity

Use helper cells instead of complex nested formulas.

Copy# WRONG - hard to debug, audit, or modify
=IF(AND(B5>100,C5<50),B5*1.1*IF(D5="A",1.2,1),B5*0.9)

# CORRECT - use helper columns
E5: =B5>100           (Threshold check)
F5: =C5<50            (Secondary check)
G5: =IF(D5="A",1.2,1) (Category multiplier)
H5: =IF(AND(E5,F5),B5*1.1*G5,B5*0.9)  (Final calculation)

Benefits:

• Each step is auditable
• Errors are easier to trace
• Business logic is visible
• Modifications are safer

Avoid Dynamic Array Functions

For maximum compatibility, avoid:

• FILTER() - not supported in older Excel
• XLOOKUP() - Excel 365+ only
• SORT() - dynamic array function
• SEQUENCE() - dynamic array function
• UNIQUE() - dynamic array function

Use classic equivalents:

• FILTER() → INDEX/MATCH with helper columns
• XLOOKUP() → INDEX/MATCH
• SORT() → manual sorting or helper columns
• SEQUENCE() → manually entered row numbers

Finance-Specific Formatting

Additional to xlsx skill standards:

Copy# Hide gridlines for cleaner appearance
sheet.sheet_view.showGridLines = False

# Add borders above totals (not around every cell)
from openpyxl.styles import Border, Side
thin_top = Border(top=Side(style='thin'))
total_cell.border = thin_top

# Cite sources in cell comments, not adjacent cells
from openpyxl.comments import Comment
cell.comment = Comment("Source: 10-K FY2024, p.45", "Analyst")

Quality Checklist

Before delivering any document:

• PNG verification completed at 100% zoom
• No clipped or overlapping text
• Tables render correctly
• Figures/images display properly
• No U+2011 or problematic Unicode
• Citations are human-readable
• Formulas use helper cells where complex
• No Excel formula errors (#REF!, #DIV/0!, etc.)
• Professional, client-ready appearance

Integration with Official Skills

This skill adds patterns on top of the document-skills plugin:

Always read both this skill AND the relevant official skill when working with documents.
