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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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.
## Mindset
Obsidian's core principle: use vault-native syntax (wikilinks, embeds, callouts) for anything that lives inside the vault, and standard Markdown only for external references or content that must render outside Obsidian.
**When to apply:** Working with `.md` files in an Obsidian vault, creating notes with wikilinks, using callouts, defining frontmatter properties, or embedding content from other notes.
**When NOT to apply:** Plain Markdown files outside a vault, GitHub READMEs, or documentation sites — Obsidian-specific syntax renders as raw text outside Obsidian.
## Workflow: Creating an Obsidian Note
1. **Add frontmatter** with properties (title, tags, aliases) at the top of the file. See [PROPERTIES.md](references/PROPERTIES.md) for all property types.

The line at the top of this page pins the label git:20260316.13efaab, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
