scenario-blender-rigging from scenario-labs/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when rigging a character, creature or prop in Blender through Python: "rig this character", Rigify metarig fitting or generation errors, automatic weights or "Bone Heat Weighting failed", weight painting fixes, clothes that do not follow, IK/FK switch, foot roll, twist bones, drivers and custom properties, corrective shape keys, a stylized face rig, a mechanical or hard-surface rig, or testing how a rig deforms.
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 rigging
Expert rigging means the rig is specified by bone placement, proven by deformation under stress
poses, and shaped around what the animator will actually use. The stance of every source expert:
place joints precisely, generate or build the simplest mechanism that works, then pose it, measure
it, render it and fix it before calling it done. If a sibling skill named here is missing from your
available skills, ask the user to install it (`npx skills add scenario-labs/skills --skill <name>`);
unattended, proceed from tool schemas and flag the gap.
**REQUIRED BACKGROUND:** scenario-blender-expert (execution channel, review loop, 5.2 API changes).
Module: [`scripts/bx_rig.py`](scripts/bx_rig.py) (tested on 5.2.1, headless and GUI).
`import sys; sys.path.append("<skills>/scenario-blender-rigging/scripts"); import bx_rig as R`.
## Stance (the expert delta)
- **Placement is the specification.** Joints sit in the center of the volume they move, not on the
anatomical skeleton ("bones simulate bone, muscle and tissue"); knees and elbows get a slight
pre-bend because the chain's curvature IS the IK plane; rolls put each hinge on one local axis so

How to install
mdr add scenario-labs/skills/scenario-blender-rigging@sha256:4958912786505235The line at the top of this page pins the label git:20261017.88ccf82, 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.
