Detection Patterns

Completeness Detection

# Find undocumented public classes
Grep: "^class |^final class |^abstract class " --glob "src/**/*.php"
# Compare with: Grep: "## " --glob "docs/api/**/*.md"

# Find undocumented public methods
Grep: "public function " --glob "src/**/*.php" | wc -l
# Compare with documented count

# Check README sections
Grep: "## Installation|## Usage|## Features" --glob "README.md"

Accuracy Detection

# Find version mismatches
Grep: "version.*[0-9]+\.[0-9]+" --glob "README.md"
# Compare with: Grep: '"version"' --glob "composer.json"

# Find non-existent paths in docs
Grep: "src/[A-Za-z/]+" --glob "docs/**/*.md"
# Verify each path exists

# Find outdated code examples
# Extract code blocks and verify they match current API

Clarity Detection

# Find undefined acronyms
Grep: "\b[A-Z]{2,}\b" --glob "docs/**/*.md"
# Check for glossary/definition nearby

# Find jargon without explanation
# Manual review of: DDD, CQRS, VO, DTO first usage

# Find walls of text (paragraphs > 5 lines)
# Manual review recommended

Navigation Detection

# Find broken internal links
Grep: "\]\((?!http)[^\)]+\)" --glob "**/*.md"
# Verify each relative path exists

# Find missing TOC in long docs (> 100 lines)
wc -l docs/**/*.md | awk '$1 > 100 {print $2}'
# Check for: Grep: "## Table of Contents|## Contents" in each

# Find orphan pages (not linked from anywhere)
# Cross-reference all .md files

Diagram Quality Detection

# Find diagrams with too many elements
Grep: "^\s*[A-Za-z].*\[|^\s*[A-Za-z].*\(" --glob "**/*.md" -A 50
# Count nodes in each mermaid block

# Find diagrams without labels
Grep: "A-->B|1-->2" --glob "**/*.md"
# Should have descriptive IDs

# Find non-rendering mermaid
# Test each ```mermaid block

Issue Severity Levels

Critical (Must Fix)

❌ Missing installation instructions
❌ Broken copy-paste examples
❌ Wrong/outdated code syntax
❌ Missing license
❌ Dead links to key resources
❌ Security-sensitive info in examples

Warning (Should Fix)

⚠️ Missing API documentation
⚠️ No usage examples
⚠️ Outdated screenshots
⚠️ Inconsistent terminology
⚠️ Missing error handling docs
⚠️ Diagrams don't match code

Info (Nice to Have)

ℹ️ No badges
ℹ️ Missing contributing guide
ℹ️ No FAQ section
ℹ️ Basic diagrams could be improved
ℹ️ Could add more examples
