What is muapi-rednote-cover?

An image-making skill for creating cover designs in the style of Xiaohongshu, also called RedNote, a Chinese social platform. It creates lifestyle-focused images with Chinese or English text.

Use it for social posts about topics such as skincare, café study videos, or fashion outfits. You can describe a visual style, add text, choose an orientation, and optionally provide a reference photo.

It helps you produce a cover that fits RedNote's portrait feed or square grid without designing the layout from scratch.

About the project

Generative-Media-Skills is a toolkit that lets AI agents generate, edit, and display images, videos, and audio through the muapi command-line interface. It is for users of Claude Code, Cursor, Gemini CLI, and OpenCode who need multimodal media-generation workflows. The catalogue entries are the skills that expose these media capabilities to coding agents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00040	$0.00853
Opus 5	$0.00020	$0.00426

Security

Grade B, and why

muapi-rednote-cover scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

`reference_image`	image_url	no	—	Optional reference photo of the subject or product.

Steps

Phase A — Cover Image

Submit the plan with ONE or TWO steps:

Cover image — If {{reference_image}} is provided, use muapi image edit (model=bytedance-seedream-v4.5-edit); otherwise use muapi image generate (model=bytedance-seedream-v4.5).
- Prompt: Xiaohongshu (RedNote/小红书) style cover photo for {{topic}} post. {{style}}. Aesthetic lifestyle photography, soft natural lighting, visually appealing composition, clean and airy feel. High engagement social media cover, editorial quality. Platform optimized for Chinese lifestyle app.
- If {{text_overlay}} is provided, append: Include elegant text overlay saying "{{text_overlay}}" in a stylish font, placed at top or bottom third of image.
- Aspect ratio: 3:4 if orientation is portrait, 1:1 if square

After generation, present the cover and offer:

A set of 3 variations with different color moods (warm / cool / neutral)
A carousel set (3 images for a RedNote carousel post)
Upscaling for print/export quality

Notes

RedNote covers perform best with: soft bokeh backgrounds, centered subjects, warm or pastel tones, and clear visual hierarchy.
If topic is fashion/outfit, suggest ugc-lifestyle-try-on skill for wearable product shots.
Korean/Japanese aesthetic filters (soft, matte, film grain) trend highly on the platform.
