  "instruction": "Rename Armature Bones to Restore Skinning `/home/user/Desktop/scene.blend`\ncontains an armature object `Rig` with a 4-bone parent chain, but the bones\nwere imported with the same generic base name. `Skin` has vertex groups\nnamed `Bone.Root`, `Bone.A`, `Bone.B`, and `Bone.Tip`, so the armature must\nbe renamed along the actual root-to-tip chain for the skinning to work.\n\n## Requirements\n1. `Rig` is an armature with exactly 4 bones.\n2. Launch Blender by running `blender` from a terminal. Use `/opt/blender/blender` for Blender command-line or background runs when working on `scene.blend`.\n\nThe bone names are exactly `{Bone.Root, Bone.A, Bone.B, Bone.Tip}`.\n3. The parent chain is `Bone.Root -> Bone.A -> Bone.B -> Bone.Tip`.\n4. `Skin` is a mesh with an Armature modifier pointing to `Rig`.\n5. `Skin`'s vertex groups are exactly the four semantic names above.\n6. Every vertex-group name resolves to a bone on `Rig`.\n\nDo not add, remove, or reparent bones; only rename them by walking the\nchain from root to tip. Save the result as `/home/user/Desktop/answer.blend`.",
