Markdown Structure Validation
Enforce consistent markdown structure across all vault content.
When to Use This Skill
Activate when you need to:
- Create new markdown documents
- Validate document structure
- Fix structural issues
- Ensure consistent formatting
Core Structure Rules
1. Frontmatter Positioning
Single YAML block at top, blank line after:
markdown
✅ CORRECT:
---
title: Document Title
created: 2025-10-31
tags:
- tag1
---
## First Section Header
Content starts here...
❌ INCORRECT:
---
title: Document Title
---
## First Section (no blank line)
❌ INCORRECT:
## Title
---
frontmatter: here
---
(frontmatter not at top)
Critical Rules:
- One YAML block only
- Must be first thing in file
- Blank line after closing
--- - No content before first heading
Note: This skill validates frontmatter POSITION (where it goes in the document). For frontmatter CONTENT (properties, values, formatting), use
obsidian-yaml-frontmatterskill.
2. Heading Hierarchy
Start with H2, no H1 duplication:
markdown
✅ CORRECT:
---
title: Document Title
---
## Introduction
Content...
### Subsection
Content...
❌ INCORRECT:
# Document Title (duplicates frontmatter title)
## Section
Hierarchy Rules:
- Use H2 (
##) for main sections - Use H3 (
###) for subsections - Use H4 (
####) sparingly - Don't skip levels (H2 → H4)
3. Content Organization
Summary-first structure:
markdown
✅ CORRECT:
---
frontmatter
---
## Summary
Overview of key points...
## Main Content
Detailed content...
## Related Topics
Links and connections...
❌ INCORRECT:
---
frontmatter
---
This is content without a heading.
## First Section
4. Quote Block Formatting
Blockquotes with attribution:
markdown
✅ CORRECT:
> "Quote text here" - Speaker/Context
> "Knowledge is power, but enthusiasm pulls the switch."
> - Ivern Ball
❌ INCORRECT:
"Quote text" (not in blockquote)
> Quote without attribution
Structure Validation Workflow
Step 1: Check Frontmatter
markdown
Verify:
- [ ] Single YAML block at top
- [ ] Blank line after closing ---
- [ ] All required properties present
- [ ] Consistent property names
Step 2: Check Heading Hierarchy
markdown
Verify:
- [ ] No H1 after frontmatter (except special cases)
- [ ] Main sections use H2
- [ ] Subsections use H3
- [ ] No skipped levels
- [ ] Logical organization
Step 3: Check Content Organization
markdown
Verify:
- [ ] No content before first heading
- [ ] Summary/overview section first
- [ ] Sections follow logical order
- [ ] Proper quote formatting
Step 4: Content-Type Specific
markdown
Check content follows appropriate template structure:
- [ ] Journal: H1 title, standard sections
- [ ] Roundup: Opening quote(s), structured headers
- [ ] Events: Executive Summary, Key Takeaways, Next Actions
- [ ] Clippings: Summary first, then detailed sections
Quality Checklist
