Obsidian Flavored Markdown Skill

Create and edit valid Obsidian Flavored Markdown. Obsidian extends CommonMark and GFM with wikilinks, embeds, callouts, properties, comments, and other syntax. This skill covers only Obsidian-specific extensions -- standard Markdown (headings, bold, italic, lists, quotes, code blocks, tables) is assumed knowledge.

Workflow: Creating an Obsidian Note

1. Add frontmatter with properties (title, tags, aliases) at the top of the file. See PROPERTIES.md for all property types.
2. Write content using standard Markdown for structure, plus Obsidian-specific syntax below.
3. Link related notes using wikilinks ([[Note]]) for internal vault connections, or standard Markdown links for external URLs.
4. Embed content from other notes, images, or PDFs using the ![[embed]] syntax. See EMBEDS.md for all embed types.
5. Add callouts for highlighted information using > [!type] syntax. See CALLOUTS.md for all callout types.
6. Verify the note renders correctly in Obsidian's reading view.

When choosing between wikilinks and Markdown links: use [[wikilinks]] for notes within the vault (Obsidian tracks renames automatically) and [text](url) for external URLs only.

Internal Links (Wikilinks)

[[Note Name]]                          Link to note
[[Note Name|Display Text]]             Custom display text
[[Note Name#Heading]]                  Link to heading
[[Note Name#^block-id]]                Link to block
[[#Heading in same note]]              Same-note heading link

Define a block ID by appending ^block-id to any paragraph:

This paragraph can be linked to. ^my-block-id

For lists and quotes, place the block ID on a separate line after the block:

> A quote block

Embeds

Prefix any wikilink with ! to embed its content inline:

See EMBEDS.md for audio, video, search embeds, and external images.

Callouts

Common types: note, tip, warning, info, example, quote, bug, danger, success, failure, question, abstract, todo.

See CALLOUTS.md for the full list with aliases, nesting, and custom CSS callouts.

Properties (Frontmatter)

Default properties: tags (searchable labels), aliases (alternative note names for link suggestions), cssclasses (CSS classes for styling).

See PROPERTIES.md for all property types, tag syntax rules, and advanced usage.

Tags

Tags can contain letters, numbers (not first character), underscores, hyphens, and forward slashes. Tags can also be defined in frontmatter under the tags property.

Comments

Obsidian-Specific Formatting

Math (LaTeX)

Diagrams (Mermaid)

```mermaid
graph TD
    A[Start] --> B{Decision}
    B -->|Yes| C[Do this]
    B -->|No| D[Do that]
```

To link Mermaid nodes to Obsidian notes, add class NodeName internal-link;.

Footnotes

Text with a footnote[^1].
 
[^1]: Footnote content.
 
Inline footnote.^[This is inline.]
