Quality

Content

85%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.

A well-structured, actionable layout skill with concrete numeric guidance, clear sequencing, and well-signaled one-level-deep references. The only meaningful weakness is repeated restatement of the module-count guidance across multiple sections.

Suggestions

State the '2-3 supporting modules (or 4-5 compact list rows)' composition rule once in Canvas Grammar and reference it from Preflight and Repair instead of restating it three times.

Tighten the bolded repair-priority paragraph to a compact ordered list, since the four-step density resolution is already implied by the surrounding diagnostic guidance.

DimensionReasoningScore

Conciseness

The body is mostly efficient and assumes Claude's competence, but the '2-3 supporting modules (or 4-5 compact list rows)' guidance is restated across Preflight, Canvas Grammar, and Repair, and the bolded repair priority paragraph reiterates already-implied guidance, so it could be tightened.

3 / 5

Actionability

Guidance is highly concrete and executable for an instruction-only skill: specific px floors (32px/28px/43px/21px), numeric height-budget ranges (64-112px, 180-360px, 160-320px, 40-64px), and tangible markers like 'data-ppt-density="high"' and '@ppt-chart-height=N' aligned with 'h-[Npx]'.

5 / 5

Workflow Clarity

A clear preflight sequence (steps 1-7) precedes writing, the Repair section provides explicit 'if X then Y' feedback loops, and 'references/checklist.md' serves as a final validation checkpoint before delivery.

5 / 5

Progressive Disclosure

The SKILL.md is an overview that points one level deep to clearly signaled, real bundle files ('references/catalog.md' for patterns and 'references/checklist.md' for self-check), with detail appropriately split out and easy to navigate.

Description

83%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.

A strong, specific description with a clear niche and concrete capability list. Its main weakness is the absence of an explicit 'Use when...' trigger clause and reliance on product jargon ('Oh My PPT') rather than broadly natural user phrasings.

Suggestions

Add an explicit 'Use when...' clause naming user-sayable triggers (e.g., 'Use when creating or repairing vertical 9:16 / portrait slides or 900x1600 canvases').

Soften reliance on the product name by pairing 'Oh My PPT pages' with generic synonyms users would actually say, such as 'vertical slides' or 'portrait story pages'.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities—'creating, relaying out, or repairing 9:16 vertical Oh My PPT pages', 'zone planning', 'vertical flow patterns', 'height budgeting', 'readable chart/list composition'—giving comprehensive coverage rather than vague domain naming.

5 / 5

Completeness

The 'what' is clearly defined and the 'when' is present via 'Must be read before creating, relaying out, or repairing 9:16 vertical Oh My PPT pages', but it lacks an explicit 'Use when...' clause with concrete user trigger phrases, so it does not fully reach the top anchor.

4 / 5

Trigger Term Quality

Natural terms like '9:16 vertical', '900x1600 canvases', and 'mobile-story layout' are present, but 'Oh My PPT' is product jargon and common user phrasings like 'portrait slide' or 'vertical slide' are missing, so it sits just below comprehensive.

4 / 5

Distinctiveness Conflict Risk

The niche is sharply defined by '9:16 vertical Oh My PPT pages' and '900x1600 canvases', yielding distinct triggers with minimal overlap risk against other skills.
