## Tools (12)

- `hbond_network`: Water H-bond network + coordination
- `hydrate_order_params`: F3 + F4 water order parameters
- `identify_cages`: Cage counts (5¹²/5¹²6⁴/…) + sI/sII/sH structure
- `list_molecules`: List loaded molecules
- `load_structure`: Load a structure/trajectory (returns a molid)
- `measure_geometry`: Distance / angle / dihedral by atom index
- `radius_of_gyration`: Rg of a selection
- `render`: Headless PNG of the current view
- `render_cages`: Photorealistic cage render (AO+shadows, ortho); filter / recolor / emphasize cages by prompt
