blender-gt-reconstruction SKILL.md skillA

blender-gt-reconstruction from llada60/3dharnessbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add llada60/3dharnessbench/blender-gt-reconstruction@git:20260925.6de69bb

Pins git:20260925.6de69bb in mdr.lock. Pin the fingerprint instead.

Reconstruct, rebuild, replicate, or visually match a ground-truth (GT) 3D model that already exists in a connected Blender MCP instance, producing a procedural, rerunnable Blender Python reconstruction. Use whenever the task says to reconstruct/rebuild/copy/match/reproduce a Blender model, scene object, or GT. Works in either access mode: (a) the GT sits in the same Blender scene as the reconstruction, compared side by side with exact measurements, or (b) the GT sits behind a separate…

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

# Blender GT reconstruction

Inspect a ground-truth 3D model that already exists in a connected Blender instance, then build a
procedurally generated reconstruction that is geometrically as close to it as practical.

Do not stop at a rough approximation. Repeatedly inspect, modify, and rerun the Blender Python
script until the reconstruction closely matches the GT.

## Step 0 — determine access mode and scope, before touching Blender

Classify the connected Blender MCP servers from the tools available to you:

* **Exactly one** Blender server, which can both inspect the scene and execute Python (an
  `execute_blender_code`-style tool), with the GT model in that scene → **same-scene mode**.
  Read [references/same-scene.md](references/same-scene.md) now.
* **Two** Blender servers, where one exposes only viewport/camera changes and screenshots — no code
  execution, no scene editing (typically named `blender-viewport-only`) → **two-instance mode**.
  The restricted server holds the GT; the full-access server is your workspace.
  Read [references/two-instance.md](references/two-instance.md) now.

How to install

The exact contents, by fingerprint
mdr add llada60/3dharnessbench/blender-gt-reconstruction@sha256:e98ef454669ab1ec

The line at the top of this page pins the label git:20260925.6de69bb, 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.
