description: Build AutoVP frame-shaped visual prompt masks and apply bounded universal prompts to resized images.
Visual Prompt Scaling
Use this skill when implementing AutoVP-style input scaling and frame prompts. Do not use it for patch-token prompt tuning or model-internal prompts.
Inputs
Source image size, target image size, channel count, image array, and prompt parameters.
Outputs
Prompt width p, binary frame mask, centered image canvas, and prompted image.
Workflow
Compute p=(source_size-target_size)//2; build a frame mask; center the image; apply a sigmoid-bounded prompt only where mask is one. Reject target sizes larger than the source input. Record odd padding decisions.
Validation
Run python tests/test_visual_prompt_scaling.py or the Distiller skill-tree validator with tests.
