Quality

Content

72%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 content is efficient and actionable with a concrete CLI workflow, but the batch re-rendering process lacks validation/verification checkpoints, which caps workflow clarity.

Suggestions

Add an explicit validation step after the parallel re-renders (e.g. verify each returned asset id is non-empty and the aspect ratio matches the requested format) with a fix-and-retry loop.

Resolve the {{caption_idea_hint}} placeholder inline rather than describing its construction, so the prompt template is copy-paste ready.

Clarify how each {{aspect_ratio}} value maps to the muapi call argument so the per-node instruction is fully executable.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence, with only minor generic boilerplate in the 'Notes for the Executing Agent' that could be trimmed.

4 / 5

Actionability

Provides concrete commands (muapi image edit with a specific model id), a prompt template, and a curl fallback, with only minor gaps around placeholder resolution and per-format call mapping.

4 / 5

Workflow Clarity

The fan-out and parallel execution sequence is clear, but this batch operation (one node per format) lacks any validation or verification step, which caps workflow clarity at 3 per the rubric.

3 / 5

Progressive Disclosure

A sub-50-line single-purpose skill with no bundle files and well-organized sections (Inputs, Steps, Notes, Triggers) qualifies for the simple-skill exception at 5.

Description

61%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 concise and names concrete platforms, but it omits any 'Use when' trigger guidance and relies on a single action, leaving the what/when balance incomplete.

Suggestions

Add a 'Use when...' clause naming natural triggers like 'Use when resizing or cross-posting a hero image to social platforms, or when the user asks for a social media pack.'

Broaden trigger terms with synonyms users actually say (e.g. 'resize', 'reformat', 'aspect ratios', 'cross-post') to improve keyword coverage.

Optionally mention the supported aspect ratios (1:1, 9:16, 4:5, 16:9) in the description to strengthen specificity and distinctiveness.

DimensionReasoningScore

Specificity

Names the domain (re-render a hero image) and one concrete action with specific platform aspect ratios, but the coverage is limited to a single transformation rather than several actions.

3 / 5

Completeness

It clearly states what the skill does but lacks any 'Use when...' clause or equivalent trigger guidance, capping completeness at 3 per the guidelines.

3 / 5

Trigger Term Quality

Natural platform names (Instagram, TikTok, YouTube-shorts, Twitter/X) are present and would be said by users, though common synonyms like 'resize', 'reformat', and aspect-ratio terms are missing.

4 / 5

Distinctiveness Conflict Risk

The niche (social-media aspect-ratio re-rendering from a hero image) is fairly distinct with low overlap risk, but the absence of explicit trigger phrasing keeps it just below a 5.
