source-part-segmentation skillA
source-part-segmentation is agent-read markdown (skill) from max-786/claude-3d-harness: Segment overlapping visual parts from source images, wireframes, texture atlases, and decals before mesh reconstruction. Use when a mascot/logo/template contains touching or overlapping components and exact structural part masks are needed before contour-to-mesh, UV fitting, or landmark repair..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Source Part Segmentation Use this before `contour-to-mesh` when a source image contains overlapping or touching designed parts. The output is not “nice masks”; it is a **source-of-truth part inventory** that downstream geometry must obey. ## Inputs - source image, wireframe, decal, or texture atlas; - optional manual seed manifest with named parts, polygons, seed points, rough rectangles, or HSV/color ranges; - source manifest with structural/decorative/context classification and expected part count. ## Workflow 1. Choose the cleanest modality: alpha, edge, dark-line, bright-on-dark, color-band, or atlas region. 2. Extract contours and hierarchy to identify candidate objects, holes, nested details, and strokes. 3. If components touch, run distance-transform marker watershed first. 4. If watershed over/under-splits, switch to **seeded segmentation**: - create named part seeds (`bbox`, `polygon`, or `seed_point` + optional flood/HSV tolerance); - save one mask per named structural part; - mark ambiguous overlaps explicitly instead of merging them. 5. Classify masks as `structural`, `decorative`, `face_feature`, `aura_context`, or `validation_only`. …

How to install
mdr add max-786/claude-3d-harness/source-part-segmentation@git:20260921.d4bf893mdr add max-786/claude-3d-harness/source-part-segmentation@sha256:190f635882edbd26Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
