source-part-segmentation SKILL.md skillA
source-part-segmentation from max-786/claude-3d-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add max-786/claude-3d-harness/source-part-segmentation@git:20260921.d4bf893Pins git:20260921.d4bf893 in mdr.lock. Pin the fingerprint instead.

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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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@sha256:190f635882edbd26The line at the top of this page pins the label git:20260921.d4bf893, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
