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):
1. 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
# 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.
# 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:
# 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)
# 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):
| Color | Meaning | Use Case |
|---|---|---|
| Gray text | Static constants | Values that never change (tax rates, conversion factors) |
| Orange background | Review/caution | Cells needing verification or approval |
| Light red background | Errors/issues | Known problems to fix |
Formula Simplicity
Use helper cells instead of complex nested formulas.
# 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 ExcelXLOOKUP()- Excel 365+ onlySORT()- dynamic array functionSEQUENCE()- dynamic array functionUNIQUE()- dynamic array function
Use classic equivalents:
FILTER()→INDEX/MATCHwith helper columnsXLOOKUP()→INDEX/MATCHSORT()→ manual sorting or helper columnsSEQUENCE()→ manually entered row numbers
Finance-Specific Formatting
Additional to xlsx skill standards:
# 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:
| Official Skill | This Skill Adds |
|---|---|
xlsx |
Helper cells, extended colors, dynamic array warnings |
pdf |
Visual-first philosophy, render-inspect-fix loop |
docx |
Typography hygiene, PNG verification emphasis |
pptx |
Same verification workflow |
Always read both this skill AND the relevant official skill when working with documents.
