We present ManiSkillFormer, a neuro-symbolic framework for demonstration-free and compositional robotic manipulation. Instead of learning end-to-end visuomotor policies, ManiSkillFormer introduces task-conditioned geometric contracts that explicitly structure the interface between perception and action. Each manipulation skill declares the semantic geometric primitives required for execution, such as object keypoints and surface normals. Building on human-defined skill structures, LLM agents generate these contracts and corresponding motion templates for different objects and task contexts. These contracts guide the perception module to ground task-relevant 3D primitives from observations, which are then used to instantiate reusable motion templates stored in a skill library. We evaluate ManiSkillFormer on Galaxea R1-Lite dual-arm robot across three settings: zero-shot pick-and-place over 8 object categories with 30 different instances, functional manipulation tasks including unscrewing, pouring, pressing, and folding, and 3 long-horizon tasks. ManiSkillFormer achieves higher average success rates than the evaluated baselines and two ablated pipelines: 88.24% for demonstration-free pick-and-place, 75.00% average success on functional manipulation and 50--80% completion rates across the long-horizon tasks. These results show that our design enables composable and reusable manipulation across objects and tasks without per-object policy fine-tuning or additional robot demonstrations.
