void Update()
{
Vector2 localPosition;

SomeBone.WorldToLocal(worldPosition.x, worldPosition.y, out localPosition.x, out localPosition.y);
SomeBone.SetPositionSkeletonSpace(localPosition);
}

I have no keyframes for this bone, tracks are cleared, but the bone jitters between initial position and position i want to set. What am i doing wrong?

if i'm doing this

SomeBone.SetLocalPosition(localPosition);

my bone is flying around

adding

skeleton.UpdateWorldTransform();

doesnt help

You should not call the code in Update(), instead call it in the respective UpdateLocal/UpdateWorld/UpdateComplete delegates as shown here:
Skeleton Utility Bone Relative/Additive override?

void Start()
    {
        skeletonAnimation = GetComponent<SkeletonAnimation>();
      skeletonAnimation.UpdateLocal += MoveBoneUpdate;

  skeleton = skeletonAnimation.Skeleton;

    bone = skeleton.FindBone("jaw");

  //Vector2 localPos;
  //bone.WorldToLocal(0, 0, out localPos.x, out localPos.y);
  //bone.SetLocalPosition(localPos);
  //bone.SetPositionSkeletonSpace(localPos);

   }

   void MoveBoneUpdate(ISkeletonAnimation s)
    {
      Vector2 localPos;
      bone.WorldToLocal(0, 0, out localPos.x, out localPos.y);
      bone.SetLocalPosition(localPos);

  //bone.SetPositionSkeletonSpace(localPos);
  //skeletonAnimation.skeleton.UpdateWorldTransform();
   }

I did like you said, but the bone is still flying around. Here is example project https://send.firefox.com/download/f144fd3fe2ddebd9/#NL7_uoUmwsbbqLnI-a4NJg

If i am setting local position only once at Start() it works well only with bone.SetPositionSkeletonSpace(localPos), but SetLocalPosition is setting the bone on wrong place, take a look. Just for notice, parent bone is rotated and i think it causes wrong position.
