Expected outcome:

The skill frames an uncrop prompt, keeps the visible face unchanged, and extends clothing, background, and lighting downward.

Security Audit

Safe

v4 • 7/5/2026 Open versioned report

The static scan mostly matched Markdown code fences, inline backticks, documentation links, and transparent CLI guidance. I found no prompt-injection attempt, hidden execution logic, or unauthorized data-exfiltration intent in SKILL.md. The skill still depends on the RunComfy CLI and external RunComfy processing, which users should understand before use.

What You Can Build

Create Campaign Banners

Extend a product or portrait image into a horizontal banner while preserving the original subject and lighting.

Adapt Social Assets

Convert square assets into vertical or wide formats for feeds, stories, and reels.

Prepare Product Catalog Frames

Use reference images or alternate routes when a simple extension needs closer style matching.

Try These Prompts

Basic Canvas Extension

Extend this image to 16:9. Keep the original subject unchanged. Match the background, lighting, and camera distance. Image URL: [URL].

Portrait Uncrop

Uncrop this head-and-shoulders portrait downward. Show more upper body and arms. Preserve the face, pose, clothing style, and existing background. Image URL: [URL].

Reference Style Match

Outpaint this image using the reference image for surrounding style. Choose the route that best preserves layout and style. Original URL: [URL]. Reference URL: [URL].

Advanced Route Recovery

Plan a multi-step outpaint for this image. Compare Nano Banana 2 Edit, GPT Image 2 Edit, FLUX Kontext Pro, and ComfyUI. Explain when to retry or switch routes. Image URL: [URL].

Best Practices

State the target aspect ratio and extension direction at the start of the prompt.
Use image URLs that the user explicitly provided and has permission to process.
Review seams, lighting, and subject preservation before using the final image.

Avoid

Do not paste secrets, private tokens, or unrelated data into image prompts.
Do not use arbitrary third-party image URLs without user approval.
Do not expect general edit endpoints to fix pixel-perfect seams every time.
