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
- Add frontmatter with properties (title, tags, aliases) at the top of the file. See PROPERTIES.md for all property types.
- Write content using standard Markdown for structure, plus Obsidian-specific syntax below.
- Link related notes using wikilinks (
[[Note]]) for internal vault connections, or standard Markdown links for external URLs. - Embed content from other notes, images, or PDFs using the
![embed]]syntax. See [EMBEDS.md for all embed types. - Add callouts for highlighted information using
> !type]syntax. See [CALLOUTS.md for all callout types. - 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 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
^quote-id
Embeds
Prefix any wikilink with ! to embed its content inline:
![[Note Name]] Embed full note
![[Note Name#Heading]] Embed section
![[image.png]] Embed image
![[image.png|300]] Embed image with width
![[document.pdf#page=3]] Embed PDF page
See EMBEDS.md for audio, video, search embeds, and external images.
Callouts
> [!note]
> Basic callout.
> [!warning] Custom Title
> Callout with a custom title.
> [!faq]- Collapsed by default
> Foldable callout (- collapsed, + expanded).
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.
