Rmbg

Background Remover (Kie.ai)

Remove backgrounds from images using Kie.ai's AI remix mode. Produces clean, transparent PNG cutouts while preserving every detail of the subject - likeness, hair, clothing, edges.

How to Use

Step 1: Identify the Source

Parse $ARGUMENTS for a file or folder path. If not provided, ask the user.

Step 2: Confirm Settings

Ask about:

• Resolution: 1K, 2K (default, recommended), or 4K
• Custom prompt (optional): If the user wants specific instructions beyond standard background removal

Show estimated cost before running:

• 1K/2K: $0.09 per image
• 4K: $0.12 per image
• Example: 5 images at 2K = $0.45

Step 3: Run

python3 ~/.claude/skills/rmbg/remove_bg.py "<file_or_folder>" \
  --resolution <1K|2K|4K> \
  [--output "<output_path>"] \
  [--prompt "<custom_prompt>"]

Step 4: Report Results

Tell the user how many images were processed, the output directory, and total cost.

Output Structure

~/images/nobg/
  photo1_nobg.png
  photo2_nobg.png

Output is always PNG (transparency requires it). Files are named <original_name>_nobg.png.

How It Works

Uses Kie.ai Nano Banana 2 in remix mode with auto aspect ratio. Uploads the original image, then generates a new version with a prompt instructing the AI to isolate the subject on a transparent background. The AI preserves all subject details while cleanly removing the background.

Rules

• Always show estimated cost before processing
• Default to 2K resolution
• Output is always PNG format (required for transparency)
• Output always goes to ~/images/nobg/ unless overridden
• Uses KIE_API_KEY from ~/.claude/.env
