unreal-geometry-script SKILL.md skillA
unreal-geometry-script from dcc-mcp/dcc-mcp-unreal is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Domain skill - read and write per-vertex skin weights on existing Unreal DynamicMesh objects through the native Geometry Script API.
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
# Dynamic Mesh Skin Weights Use `get_vertex_bone_weights` and `set_vertex_bone_weights` with the exact `get_path_name()` of an existing `unreal.DynamicMesh`. The mesh must already exist in this editor session. Both tools run on the editor thread. The default profile is the native SDK default. A named profile must be a nonempty name with no whitespace and must not be the reserved name `None`. Reads fail if the vertex or profile is missing. Writes create a missing profile without resetting other profiles. Input weights must be finite, nonnegative, normalized, use unique bone indices in the native uint16 range, and contain at most 12 influences. Results report the host readback instead of validating it: `bone_weights` holds the host values with zero-weight native padding slots omitted, plus `influence_count`, `weight_sum`, `normalized`, and `sum_abs_tol` diagnostics. Native 16 bit quantization can leave a valid readback slightly off 1, so `normalized` uses `1e-4` while input weights are still held to `1e-6`. A write reports `success` once the SDK accepted the vertex. Its `verified` flag and `readback_error` describe the readback only: a write that landed is …

How to install
mdr add dcc-mcp/dcc-mcp-unreal/unreal-geometry-script@sha256:8d9561383ad8c07dThe line at the top of this page pins the label git:20260930.cf25363, 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.
