The body is lean and explicitly states 'standard Markdown... is assumed knowledge', avoiding re-teaching concepts Claude already knows; every section adds only Obsidian-specific syntax, matching the lean-and-efficient anchor.

Each feature ships as concrete, copy-paste-ready syntax blocks (wikilinks, embeds, callouts, properties, tags, comments, math, mermaid, footnotes) plus a complete worked example, matching the fully-executable anchor.

The 'Workflow: Creating an Obsidian Note' section gives a clear six-step sequence ending with an explicit 'Verify the note renders correctly' validation checkpoint, matching the clear-sequence-with-validation anchor.

A concise overview points to three clearly signaled, one-level-deep references (CALLOUTS.md, EMBEDS.md, PROPERTIES.md), all of which exist as real files in references/, matching the well-signaled one-level-deep anchor.

Lists multiple concrete actions ('Create and edit Obsidian Flavored Markdown with wikilinks, embeds, callouts, properties'), matching the top anchor that lists several specific actions.

Explicitly answers what ('Create and edit Obsidian Flavored Markdown...') and when ('Use when working with .md files in Obsidian, or when the user mentions...'), satisfying the both-what-and-when anchor.

Natural terms users would say are well covered: 'wikilinks, callouts, frontmatter, tags, embeds, or Obsidian notes' plus '.md files in Obsidian', matching the good-coverage anchor.

The Obsidian-specific syntax niche with distinct trigger terms (wikilinks, callouts, embeds) makes conflict with other skills unlikely, matching the clear-niche anchor.
