spatial-interchange SKILL.md skillA
spatial-interchange from dcc-mcp/dcc-mcp-core is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dcc-mcp/dcc-mcp-core/spatial-interchange@git:20261008.42e6de5Pins git:20261008.42e6de5 in mdr.lock. Pin the fingerprint instead.

Plan deterministic coordinate-axis and unit conversions between DCCs, engines, and interchange formats from explicit right/up/forward axes and meters-per-unit values.
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
# Spatial Interchange Use `plan_conversion` before a cross-DCC import or export when source and target coordinate conventions are known. The tool returns a pure conversion plan; the importing or exporting adapter remains responsible for applying it to scene data. Do not infer a convention from a DCC name alone. Query the live scene, import settings, or file metadata first: Maya up-axis and units are scene settings, Blender FBX axes are operator settings, and USD stages carry `upAxis` and `metersPerUnit` metadata. The [3D Transform Visualizer](https://aike.github.io/3dtr/) is a useful educational model for signed right/up/forward bases. It is not a file converter or a source of truth for a live scene. ## Workflow 1. Inspect source file/scene axes and physical units. 2. Inspect the target scene/importer settings. 3. Call `plan_conversion` with explicit signed axes and meters per unit. 4. Apply the returned plan in the owning adapter/importer. 5. Validate a landmark point, bounds, face orientation, normals, and animation. Read `references/CONVENTIONS.md` for official defaults, runtime caveats, and the rules for positions, directions, transforms, and mesh winding.

How to install
mdr add dcc-mcp/dcc-mcp-core/spatial-interchange@sha256:a1b6cff8cb634944The line at the top of this page pins the label git:20261008.42e6de5, 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.
