Content

27%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This skill is essentially a comprehensive Obsidian Markdown syntax reference that Claude largely already knows. It is extremely verbose, documenting standard Markdown features (headings, bold, lists, code blocks, tables) alongside Obsidian-specific ones without distinction. The skill would be far more effective if it focused only on Obsidian-specific syntax (wikilinks, embeds, callouts, properties, block references) and provided workflow guidance for common editing tasks rather than serving as a syntax cheat sheet.

Suggestions

Remove all standard Markdown documentation (headings, bold, italic, lists, code blocks, tables, footnotes, math, mermaid) — Claude already knows these. Focus only on Obsidian-specific syntax like wikilinks, embeds, callouts, properties, block references, and comments.

Add a workflow section describing how to approach creating/editing Obsidian notes: e.g., check for existing frontmatter, validate YAML properties, ensure wikilinks use correct note paths, verify embed file references exist.

Move the callout types table and the complete example note into separate bundle files (e.g., CALLOUT_TYPES.md, EXAMPLE.md) and reference them from the main skill to reduce context window usage.

Add decision guidance for common choices: when to use wikilinks vs standard markdown links, when to use inline tags vs frontmatter tags, when to use block references vs heading links.

DimensionReasoningScore

Conciseness

Extremely verbose — most of this content documents standard Markdown and Obsidian syntax that Claude already knows (headings, bold, italic, lists, code blocks, tables, footnotes, math, mermaid). The skill is essentially a reformatted copy of the Obsidian help docs. Very few tokens here add knowledge Claude doesn't already possess.

1 / 3

Actionability

The examples are concrete and copy-paste ready markdown snippets, which is good. However, the skill is a reference document rather than actionable guidance — it doesn't instruct Claude on how to approach tasks like creating or editing Obsidian files, handling edge cases, or making decisions about which syntax to use in specific situations.

2 / 3

Workflow Clarity

There is no workflow or multi-step process defined. The 'When to Use This Skill' section lists triggers but doesn't describe a process for creating or editing Obsidian notes. For a reference-style skill this is somewhat acceptable, but there's no guidance on validation (e.g., checking frontmatter validity, ensuring wikilinks resolve) or sequencing of edits.

2 / 3

Progressive Disclosure

The entire skill is a monolithic wall of text (~300+ lines) with no references to supporting files. Content like the complete callout types table, the full example note, and basic formatting sections could easily be split into separate reference files. Everything is inlined, making the skill consume excessive context window space.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is an excellent skill description that hits all the marks. It uses third person voice, lists specific capabilities, includes a comprehensive 'Use when...' clause with natural trigger terms, and is clearly distinguishable from generic Markdown or document editing skills. It closely matches the good examples provided in the rubric.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions and features: 'Create and edit Obsidian Flavored Markdown with wikilinks, embeds, callouts, properties, and other Obsidian-specific syntax.' This enumerates distinct capabilities clearly.

3 / 3

Completeness

Clearly answers both 'what' (create and edit Obsidian Flavored Markdown with specific syntax features) and 'when' (explicit 'Use when...' clause listing file types and trigger terms like wikilinks, callouts, frontmatter, tags, embeds, Obsidian notes).

3 / 3

Trigger Term Quality

Excellent coverage of natural terms users would say: 'Obsidian', '.md files', 'wikilinks', 'callouts', 'frontmatter', 'tags', 'embeds', 'Obsidian notes'. These are all terms a user would naturally use when requesting help with Obsidian content.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive — 'Obsidian Flavored Markdown' and Obsidian-specific syntax elements like wikilinks, callouts, and embeds clearly distinguish this from generic Markdown or other document editing skills. Unlikely to conflict with other skills.
