## Tools (5)

- `calculate_decentration`: Symmetric boxing frame only: (A + bridge)/2 minus monocular PD, per eye, in mm. Positive nasal; negative temporal. No vertical or prescribed prism compensation.
- `calculate_prism`: Educational Prentice approximation: absolute meridional power times displacement in cm. Returns magnitude only, no base direction or prescription recommendation.
- `get_optical_topic`: Read a public optical topic by stable ID with references, related topics and limitations.
- `search_optical_knowledge`: Search public optical education in Portuguese or English. Returns source excerpts, not medical advice or customer records.
- `transpose_prescription`: Transpose sphere/cylinder notation without changing the prescription. Dioptres and degrees; axis 0–180. Does not diagnose or generate prescriptions.
