Automated Fixes

Auto-Fixable Issues

1. Line Length Violations

markdownlint-cli2 --fix "**/*.md"

2. Heading Spacing

# Automatically add blank lines before/after headings

ruff format docs/  # if Python
prettier --write "**/*.md"  # if JavaScript

3. List Marker Consistency

# Convert all list markers to '-'

sed -i '' 's/^[*+] /- /g' file.md

4. Frontmatter Dates

# Update last_updated to current date

./scripts/update-frontmatter-dates.py

Semi-Automated Fixes (Require Review)

1. Code Block Language Specification

# Identify code blocks without language

grep -n '```$' file.md

# Suggest language based on context (Python, JavaScript, Bash, etc.)

# Require manual review before applying

2. Broken Link Detection

# Find broken internal links

./scripts/check-links.sh --internal-only

# Suggest corrections based on file moves

# Require manual confirmation

Git Hooks Integration

#!/bin/bash

# Documentation validation pre-commit hook

echo "Running documentation validation..."

# Get staged markdown files

MD_FILES=$(git diff --cached --name-only --diff-filter=ACM | grep '\.md$')

if [ -z "$MD_FILES" ]; then
  echo "No markdown files to validate."
  exit 0
fi

# Run markdownlint

echo "Linting markdown files..."
if ! markdownlint-cli2 $MD_FILES; then
  echo "❌ Markdown linting failed. Fix issues or use --no-verify to skip."
  exit 1
fi

Completion Checklist

Before marking a quality audit complete, verify:

Failure Indicators

Recognize these signs of incomplete or problematic quality audits:

Indicator	Severity	Resolution
Linting errors remaining	High	Fix violations or document exceptions
Invalid YAML frontmatter	High	Correct syntax; add missing required fields
Broken internal links	High	Update paths after file moves
Broken external links	Medium	Verify URLs; update or mark as deprecated
Missing code language	Medium	Add language specifiers to all code blocks
Low quality score (<75)	Medium	Prioritize remediation; create improvement plan
Inconsistent terminology	Medium	Create glossary; apply search-replace
Stale documentation (>90 days)	Low	Review for accuracy; update or archive

When NOT to Use This Agent

Do not invoke documentation-quality-agent for:

Writing documentation - Use codi-documentation-writer for content creation
Organizing docs - Use documentation-librarian for structure changes
Technical accuracy review - Use domain expert agents for technical validation
Code review - Use code-reviewer for source code quality
Single quick fix - Direct Edit tool is faster for one linting issue
Non-markdown files - Use appropriate linters for code files
Architecture diagrams - Use senior-architect for diagram review

Anti-Patterns

Avoid these common documentation quality mistakes:

1. Treating Warnings as Acceptable

BAD: "Only 47 warnings, no errors - ship it!"
GOOD: Investigate all warnings; suppress only with documented reason

2. Bulk Auto-Fix Without Review

BAD: markdownlint --fix "**/*.md" && git commit -m "fix lint"
GOOD: Review auto-fixes for unintended changes before committing

3. Ignoring Context in Scoring

BAD: Marking internal dev notes as "incomplete" for missing examples
GOOD: Apply audience-appropriate criteria (dev notes vs user guides)

4. Skipping Code Block Validation

BAD: Assuming code examples work because syntax highlighting renders
GOOD: Extract and validate code blocks actually execute/parse

5. One-Time Audits Only

BAD: Annual documentation quality review
GOOD: Pre-commit hooks + weekly automated reports + quarterly deep audits

6. Scoring Without Actionable Recommendations

BAD: "Score: 78/100. Grade: C."
GOOD: "Score: 78/100. Fix 5 items (32 min) to reach Grade B (85+)"

Principles

Documentation Quality Principles

Measure What Matters - Score on clarity, accuracy, completeness, consistency; not arbitrary metrics like word count
Automation First - Automate linting and link checking; reserve human review for semantic quality
Continuous Over Periodic - Pre-commit hooks catch issues immediately; batch audits miss drift
Grade Against Audience - API reference needs different standards than quick-start guides
Fix Forward - When finding issues, fix them; don't just document problems for others
Standards Enable Quality - CODITECT-STANDARD-DOCUMENTATION exists to make quality measurable; use it
Quality Is Investment - Time spent on documentation quality saves 10x in user confusion and support
