Lanhu Design

Read Lanhu UI designs, extract slices, and download Web/iOS/Android assets using lh-design. Use when the user mentions 蓝湖, Lanhu, UI稿, 设计稿, 切图, iOS @2x/@3x, Android drawable, or Web 1x/2x/3x assets.

Prerequisites

Use the lh-design CLI from xuwenxindeai/lanhu-design-reader.

If lh-design is missing, do not run remote installer commands from this skill. Ask the user to install lh-design from the project README, then verify with lh-design --help.

The default installer paths are:

Source: ~/.lanhu-design-reader/src
Virtualenv: ~/.lanhu-design-reader/venv
Config: ~/.lanhu-design-reader/.env
Command: ~/.local/bin/lh-design

The user must provide LANHU_COOKIE via shell env, a local .env, or ~/.lanhu-design-reader/.env. If DDS schema reads need a separate login state, use DDS_COOKIE.

Workflow

1. Parse the user's Lanhu URL and identify image_id. If the URL already includes image_id or docId, --image-id may be omitted.
2. Inspect slices first:

lh-design slices '<Lanhu URL>' --image-id <image_id> -o slices.json

3. Download assets for the target platform.

Web:

lh-design download-slices '<Lanhu URL>' --image-id <image_id> --scale 1x -o web_1x
lh-design download-slices '<Lanhu URL>' --image-id <image_id> --scale 2x -o web_2x
lh-design download-slices '<Lanhu URL>' --image-id <image_id> --scale 3x -o web_3x

iOS:

lh-design download-slices '<Lanhu URL>' --image-id <image_id> --scale ios_2x -o ios_2x
lh-design download-slices '<Lanhu URL>' --image-id <image_id> --scale ios_3x -o ios_3x

Android:

lh-design download-slices '<Lanhu URL>' --image-id <image_id> --scale android_mdpi -o drawable-mdpi
lh-design download-slices '<Lanhu URL>' --image-id <image_id> --scale android_hdpi -o drawable-hdpi
lh-design download-slices '<Lanhu URL>' --image-id <image_id> --scale android_xhdpi -o drawable-xhdpi
lh-design download-slices '<Lanhu URL>' --image-id <image_id> --scale android_xxhdpi -o drawable-xxhdpi
lh-design download-slices '<Lanhu URL>' --image-id <image_id> --scale android_xxxhdpi -o drawable-xxxhdpi

Important

• Web uses 1x/2x/3x, not ios_*.
• iOS uses ios_2x/ios_3x.
• Android uses android_mdpi/android_hdpi/android_xhdpi/android_xxhdpi/android_xxxhdpi.
• For Photoshop uploads, base_size equals iOS @2x / Android xhdpi.
• Prefer slices.json as the source of truth before renaming or moving assets.
