# Turn an existing cover into a clearer publishing decision

Cover Improvement Preflight reviews an existing YouTube thumbnail, social media cover, article cover, or podcast cover for the visual hook, focal hierarchy, title fit, text-safe contrast, mobile readability, and crop resilience. The findings become targeted edit directions and two or three improved 2K PNG candidates to compare, with an optional benchmark of the titles and public counts already ranking for the same topic on YouTube, TikTok, Douyin, and REDnote. Cover Improvement Preflight works in Claude Code, Codex, Cursor, and other agents that run Skills.

## A practical preflight that turns observations into edit decisions

### Review the real viewing context

Assess the visual hook, focal order, title relationship, small-screen readability, and likely crops for the intended surface.

### Compare distinct directions

Turn the findings into two or three purposeful candidates instead of making unrelated cosmetic variations.

## How it is made

### Build the preflight card · See what the cover communicates at a glance

Review the visible hook, attention path, title relationship, text contrast, mobile readability, crop behavior, and brand-defining details.

- Destination and audience
- Visual hook and focal hierarchy
- Title and text-safe contrast
- Mobile and crop checks

### Develop comparison directions · Make the smallest useful changes easy to compare

Translate the review into a focused revision plan and two or three candidates with clearly different visual strategies.

- Protected brand and content details
- One primary improvement per direction
- Consistent destination and canvas
- Side-by-side review guidance

## Cover reviews for video, social, editorial, and podcasts

### YouTube and video thumbnails

Clarify the first-read subject, title-to-image fit, and mobile-scale contrast before publication or platform comparison.

### Social and article covers

Check focal hierarchy, text-safe areas, and crop resilience across feed, card, and hero placements.

### Podcast artwork

Protect recognizability at small sizes while improving title balance, contrast, and supporting detail.

## Questions

### How should I compare the cover candidates?

Compare the first-read subject, title relationship, small-screen contrast, crop behavior, and brand recognition under the same publishing context.

### Which cover types can I review?

Use an existing YouTube thumbnail, social-media cover, article hero image, or podcast cover together with its title and destination.

### What do I need to provide?

Provide the existing cover, its title or core message, the intended platform, audience, and any brand details that should remain. Add your YouTube channel URL if you want your own recent thumbnails compared.
