obsidian-markdown
💡 Summary
A reference skill for generating and editing Obsidian Flavored Markdown, including wikilinks, callouts, properties, and other Obsidian-specific syntax.
🎯 Target Audience
🤖 AI Roast: “It's a comprehensive Markdown cheat sheet masquerading as an AI skill, offering more syntax reference than actual agentic capability.”
Risk: The skill is a pure text generation reference with no inherent execution, network, or file system access. The primary risk is indirect: an agent using this skill might generate Markdown that, when executed by Obsidian plugins, could trigger unsafe operations (e.g., `obsidian://` URI handlers, embedded script tags). Mitigation: Agents should sanitize user input before passing it to this skill and treat generated Markdown as untrusted content before writing to disk.
name: obsidian-markdown description: Create and edit Obsidian Flavored Markdown with wikilinks, embeds, callouts, properties, and other Obsidian-specific syntax. Use when working with .md files in Obsidian, or when the user mentions wikilinks, callouts, frontmatter, tags, embeds, or Obsidian notes.
Obsidian Flavored Markdown Skill
This skill enables skills-compatible agents to create and edit valid Obsidian Flavored Markdown, including all Obsidian-specific syntax extensions.
Overview
Obsidian uses a combination of Markdown flavors:
- CommonMark
- GitHub Flavored Markdown
- LaTeX for math
- Obsidian-specific extensions (wikilinks, callouts, embeds, etc.)
Basic Formatting
Paragraphs and Line Breaks
This is a paragraph. This is another paragraph (blank line between creates separate paragraphs). For a line break within a paragraph, add two spaces at the end or use Shift+Enter.
Headings
# Heading 1 ## Heading 2 ### Heading 3 #### Heading 4 ##### Heading 5 ###### Heading 6
Text Formatting
| Style | Syntax | Example | Output |
|-------|--------|---------|--------|
| Bold | **text** or __text__ | **Bold** | Bold |
| Italic | *text* or _text_ | *Italic* | Italic |
| Bold + Italic | ***text*** | ***Both*** | Both |
| Strikethrough | ~~text~~ | ~~Striked~~ | ~~Striked~~ |
| Highlight | ==text== | ==Highlighted== | ==Highlighted== |
| Inline code | `code` | `code` | code |
Escaping Formatting
Use backslash to escape special characters:
\*This won't be italic\* \#This won't be a heading 1\. This won't be a list item
Common characters to escape: \*, \_, \#, \`, \|, \~
Internal Links (Wikilinks)
Basic Links
[[Note Name]] [[Note Name.md]] [[Note Name|Display Text]]
Link to Headings
[[Note Name#Heading]] [[Note Name#Heading|Custom Text]] [[#Heading in same note]] [[##Search all headings in vault]]
Link to Blocks
[[Note Name#^block-id]] [[Note Name#^block-id|Custom Text]]
Define a block ID by adding ^block-id at the end of a paragraph:
This is a paragraph that can be linked to. ^my-block-id
For lists and quotes, add the block ID on a separate line:
> This is a quote > With multiple lines ^quote-id
Search Links
[[##heading]] Search for headings containing "heading" [[^^block]] Search for blocks containing "block"
Markdown-Style Links
[Display Text](Note%20Name.md) [Display Text](Note%20Name.md#Heading) [Display Text](https://example.com) [Note](obsidian://open?vault=VaultName&file=Note.md)
Note: Spaces must be URL-encoded as %20 in Markdown links.
Embeds
Embed Notes
![[Note Name]] ![[Note Name#Heading]] ![[Note Name#^block-id]]
Embed Images
![[image.png]] ![[image.png|640x480]] Width x Height ![[image.png|300]] Width only (maintains aspect ratio)
External Images
 
Embed Audio
![[audio.mp3]] ![[audio.ogg]]
Embed PDF
![[document.pdf]] ![[document.pdf#page=3]] ![[document.pdf#height=400]]
Embed Lists
![[Note#^list-id]]
Where the list has been defined with a block ID:
- Item 1 - Item 2 - Item 3 ^list-id
Embed Search Results
```query tag:#project status:done ```
Callouts
Basic Callout
> [!note] > This is a note callout. > [!info] Custom Title > This callout has a custom title. > [!tip] Title Only
Foldable Callouts
> [!faq]- Collapsed by default > This content is hidden until expanded. > [!faq]+ Expanded by default > This content is visible but can be collapsed.
Nested Callouts
> [!question] Outer callout > > [!note] Inner callout > > Nested content
Supported Callout Types
| Type | Aliases | Description |
|------|---------|-------------|
| note | - | Blue, pencil icon |

.callout[data-callout="custom-type"] { --callout-color: 255, 0, 0; --callout-icon: lucide-alert-circle; }
Lists
Unordered Lists
- Item 1 - Item 2 - Nested item - Another nested - Item 3 * Also works with asterisks + Or plus signs
Ordered Lists
1. First item 2. Second item 1. Nested numbered 2. Another nested 3. Third item 1) Alternative syntax 2) With parentheses
Task Lists
- [ ] Incomplete task - [x] Completed task - [ ] Task with sub-tasks - [ ] Subtask 1 - [x] Subtask 2
Quotes
> This is a blockquote. > It can span multiple lines. > > And include multiple paragraphs. > > > Nested quotes work too.
Code
Inline Code
Use `backticks` for inline code. Use double backticks for ``code with a ` backtick inside``.
Code Blocks
``` Plain code block ``` ```javascript // Syntax highlighted code block function hello() { console.log("Hello, world!"); } ``` ```python # Python example def greet(name): print(f"Hello, {name}!") ```
Nesting Code Blocks
Use more backticks or tildes for the outer block:
````markdown Here's how to create a code block: ```js console.log("Hello") ``` ````
Tables
| Header 1 | Header 2 | Header 3 | |----------|----------|----------| | Cell 1 | Cell 2 | Cell 3 | | Cell 4 | Cell 5 | Cell 6 |
Alignment
| Left | Center | Right | |:---------|:--------:|---------:| | Left | Center | Right |
Using Pipes in Tables
Escape pipes with backslash:
| Column 1 | Column 2 | |----------|----------| | [[Link\|Display]] | ![[Image\|100]] |
Math (LaTeX)
Inline Math
This is inline math: $e^{i\pi} + 1 = 0$
Block Math
$$ \begin{vmatrix} a & b \\ c & d \end{vmatrix} = ad - bc $$
Common Math Syntax
$x^2$ Superscript $x_i$ Subscript $\frac{a}{b}$ Fraction $\sqrt{x}$ Square root $\sum_{i=1}^{n}$ Summation $\int_a^b$ Integral $\alpha, \beta$ Greek letters
