Quality

Content

86%Weight 40%Scale 1-5

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

The body is a tight, well-structured overview with concrete commands and a clear availability/fallback branch. Slight headroom remains on actionability (placeholders) and on making the fallback workflow's verification of success more explicit.

DimensionReasoningScore

Conciseness

Lean and efficient: a one-paragraph rule, a compact command table, and a handful of fallback commands, with no padding or re-explanation of concepts Claude already knows.

5 / 5

Actionability

Provides concrete, mostly executable commands (the /preview command table and pandoc/open fallbacks), but placeholders like '<file.md>' and 'when available' hedges leave minor gaps versus fully copy-paste-ready examples.

4 / 5

Workflow Clarity

Clear two-branch decision (use /preview when visible, else fall back to shell/browser tools and report the package is not installed); no destructive or batch operation, so the validation cap does not apply, but explicit checkpoints beyond the report step are absent.

4 / 5

Progressive Disclosure

Under 50 lines with no need for external references, and content is organized into well-labeled sections (# Preview, ## Commands, ## Fallback), satisfying the simple-skill exception.

Description

78%Weight 40%Scale 1-5

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

The description is well-formed: third-person voice, explicit what-and-when, and natural trigger phrases. Main gap is action breadth (preview + fallback) rather than a richer action vocabulary.

DimensionReasoningScore

Specificity

Names a concrete domain ('Markdown, LaTeX, PDF, or code artifacts') and two behaviors ('Preview ... when preview commands are visible' and 'fall back to shell/browser tools'), but the action set is essentially preview + fallback rather than a comprehensive list of distinct operations.

3 / 5

Completeness

Explicitly answers what ('Preview Markdown, LaTeX, PDF, or code artifacts ... or fall back to shell/browser tools') and when ('Use when the user wants to review a written artifact, export a report, or view a rendered document') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural user phrases ('review a written artifact', 'export a report', 'view a rendered document') and format keywords (Markdown, LaTeX, PDF), but omits common synonyms and file extensions.

4 / 5

Distinctiveness Conflict Risk

Targets a clear niche (previewing/rendering written artifacts) with distinct triggers, though 'code artifacts' is somewhat broad and could lightly overlap with code-tooling skills.
