Documentation linting automatically detects formatting issues, broken references, and structural problems in markdown files. This skill provides comprehensive validation strategies for:

Header Structure: Duplicate H1s, level skipping, hierarchy violations
Code Blocks: Missing language declarations, unclosed blocks, syntax issues
Links: Broken references, invalid paths, protocol consistency
Lists: Marker consistency (mixing - and *), indentation problems
Tables: Column count mismatch, alignment issues
Typography: Trailing whitespace, full-width characters, encoding issues

Key Benefits:

Catch errors before documentation builds
Ensure consistency across all documents
Improve readability and user experience
Validate multilingual document structure

Section 2: Core Linting Rules

Header Validation

Rules:
  - H1 (# Title): Exactly 1 per document
  - H2-H6 (## Subtitle, etc.): Can be multiple
  - Level Hierarchy: No skipping levels (# → ## → ###)
  - Duplicates: No duplicate headers on same level
  - Special Characters: No emojis in headers (MoAI-ADK standard)

Example - Good:

# Main Title (single H1)

---

### Level 2: Practical Implementation (Common Patterns)

### Section 1: Linting Overview

Documentation linting automatically detects formatting issues, broken references, and structural problems in markdown files. This skill provides comprehensive validation strategies for:

- **Header Structure**: Duplicate H1s, level skipping, hierarchy violations
- **Code Blocks**: Missing language declarations, unclosed blocks, syntax issues
- **Links**: Broken references, invalid paths, protocol consistency
- **Lists**: Marker consistency (mixing `-` and `*`), indentation problems
- **Tables**: Column count mismatch, alignment issues
- **Typography**: Trailing whitespace, full-width characters, encoding issues

**Key Benefits**:
- Catch errors before documentation builds
- Ensure consistency across all documents
- Improve readability and user experience
- Validate multilingual document structure

### Section 2: Core Linting Rules

#### Header Validation

```yaml
Rules:
  - H1 (# Title): Exactly 1 per document
  - H2-H6 (## Subtitle, etc.): Can be multiple
  - Level Hierarchy: No skipping levels (# → ## → ###)
  - Duplicates: No duplicate headers on same level
  - Special Characters: No emojis in headers (MoAI-ADK standard)

Example - Good:

# Main Title (single H1)

---

Section 2
### Subsection 2.1

Example - Bad:

# Title 1
# Title 2        ❌ Multiple H1s

---

Subsection
#### Deep level   ❌ Skipped H3

Code Block Validation

Rules:
  - Language Declaration: Every block must specify language
  - Matching Delimiters: Opening ``` must match closing ```
  - Placement: Code blocks on separate lines
  - Content: Valid code examples

Example - Good:

\`\`\`python
def hello():
    print("Hello, World!")
\`\`\`

Example - Bad:

\`\`\`
def hello():
\`\`\`python    ❌ Mismatched delimiters

\`\`\`          ❌ No language specified
def hello():
\`\`\`

Link Validation

Rules:
  - Relative Links: Use ../ for cross-directory navigation
  - External Links: Must use https:// protocol
  - Valid References: All linked files must exist
  - Anchor Links: Point to valid headers

Example - Good:

[Install Guide](../getting-started/installation.md)
[External](https://example.com)
[Section](#header-anchor)

Example - Bad:

[Link](../../nonexistent.md)           ❌ File doesn't exist
[Link](http://example.com)             ❌ Not https
[Link](#invalid-section)               ❌ Header doesn't exist

List Validation

Rules:
  - Marker Consistency: Don't mix - and * in same list
  - Indentation: Use 2-4 spaces (never tabs)
  - Nesting: Consistent indentation for nested items
  - Separator: Blank line required after list

Example - Good:

- Item 1
- Item 2
  - Nested 2.1
  - Nested 2.2
- Item 3

Example - Bad:

- Item 1
* Item 2           ❌ Mixed markers
	- Item 3       ❌ Tab indentation

Table Validation

Rules:
  - Column Consistency: All rows must have same column count
  - Header Line: Required | --- | separator
  - Alignment: Optional but consistent :--|:--:|--:

Example - Good:

| Header 1 | Header 2 | Header 3 |
|----------|----------|----------|
| Cell 1   | Cell 2   | Cell 3   |
| Cell 4   | Cell 5   | Cell 6   |

Example - Bad:

| Header 1 | Header 2
| Cell 1   | Cell 2 | Cell 3   |  ❌ Column mismatch

Section 3: Multilingual Linting

For Korean Documents (ko/):

UTF-8 Encoding: Verify encoding consistency
Full-width Characters: Avoid U+3000 (full-width space)
Typography: Proper spacing around Korean-English boundaries
Capitalization: Consistent title casing

For Other Languages (en/, ja/, zh/):

Language-specific rules
Consistent structure matching Korean source
Translation quality validation

Section 4: Automation & Tooling

Python Linting Script Pattern:

class DocumentationLinter:
    def __init__(self, docs_path: str):
        self.docs_path = Path(docs_path)
        self.errors = []
        self.warnings = []

    def lint_headers(self, content: str) -> List[str]:
        """Validate header structure"""
        h1_count = len(re.findall(r'^# ', content, re.MULTILINE))
        if h1_count != 1:
            return [f"Error: Found {h1_count} H1 headers (expected 1)"]
        return []

    def lint_code_blocks(self, content: str) -> List[str]:
        """Validate code block pairs"""
        issues = []
        # Check for ```language declaration
        # Check for matching delimiters
        # Validate content
        return issues

    def lint_links(self, content: str, file_path: Path) -> List[str]:
        """Validate link references"""
        # Find all [text](path) patterns
        # Verify file existence
        # Check protocol (https for external)
        return issues

Integration with CI/CD:

# Pre-commit validation
python3 .moai/scripts/lint_korean_docs.py
python3 .moai/scripts/validate_mermaid_diagrams.py
python3 .moai/scripts/validate_korean_typography.py

# Generate comprehensive report
python3 .moai/scripts/generate_final_comprehensive_report.py

Section 5: MoAI-ADK Standards

Header Style (from November 9 validation):

✅ No emojis in headers (text only)
✅ Material Icons allowed in body text (not headers)
✅ Clear hierarchy (H1 → H2 → H3)

Link Standards:

✅ Use relative paths within language directories
✅ Use https:// for external links
✅ Descriptive link text (avoid "click here")

Code Block Standards:

✅ Always specify language (python, javascript, bash, etc.)
✅ Real, tested examples
✅ Clear explanations

Internationalization:

✅ Same structure across ko/, en/, ja/, zh/
✅ UTF-8 encoding for all files
✅ Consistent terminology across languages

✅ Validation Checklist
