Conciseness

The skill is efficient and assumes Claude knows standard Markdown. The 'When to Use' section is slightly redundant with the YAML description and frontmatter, and a few minor explanations (e.g., 'Obsidian extends CommonMark and GFM') could be trimmed, but overall it's lean and well-targeted.

Actionability

Every syntax feature includes copy-paste ready Markdown examples with clear annotations. The complete example at the end ties everything together into a fully executable note. Code is concrete and covers common cases comprehensively.

Workflow Clarity

The workflow section provides a clear 6-step sequence for creating an Obsidian note, with references to detailed guides at each step. Step 6 ('Verify the note renders correctly') is a validation checkpoint, though it's somewhat vague — it doesn't specify what to check or how to handle rendering issues. Since this is a non-destructive content creation task, the lack of a detailed feedback loop is a minor gap rather than a critical one.

Progressive Disclosure

The skill provides a clear overview with well-signaled references to EMBEDS.md, CALLOUTS.md, and PROPERTIES.md for detailed content. However, no bundle files were provided, so we can't verify these references exist. The inline content is appropriately scoped — enough to be useful without being overwhelming — with clear pointers to deeper material. Minor gap: the external reference links at the bottom could be better integrated.

Specificity

Lists several specific actions and features (wikilinks, embeds, callouts, properties, Obsidian-specific syntax) with 'create and edit' as concrete actions. Minor gaps - could mention more specific operations like linking notes, creating templates, or managing metadata.

Completeness

Clearly answers both 'what' (create and edit Obsidian Flavored Markdown with specific features) and 'when' (explicit 'Use when' clause with concrete trigger phrases including file extensions and feature names).

Trigger Term Quality

Comprehensive coverage of natural terms users would say: 'Obsidian', 'wikilinks', 'callouts', 'frontmatter', 'tags', 'embeds', 'Obsidian notes', '.md files'. Includes both technical terms and common user language, plus the file extension.

Distinctiveness Conflict Risk

Clearly distinct from generic markdown skills by specifying 'Obsidian Flavored Markdown' and Obsidian-specific features like wikilinks, embeds, and callouts. The trigger terms are highly specific to Obsidian's ecosystem, minimizing conflict with general markdown or note-taking skills.
