Changes things 3Claude Code: ask
  • calculate_decentrationSymmetric boxing frame only: (A + bridge)/2 minus monocular PD, per eye, in mm.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Symmetric boxing frame only: (A + bridge)/2 minus monocular PD, per eye, in mm. Positive nasal; negative temporal. No vertical or prescribed prism compensation.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • calculate_prismEducational Prentice approximation: absolute meridional power times displacement in cm.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Educational Prentice approximation: absolute meridional power times displacement in cm. Returns magnitude only, no base direction or prescription recommendation.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • transpose_prescriptionTranspose sphere/cylinder notation without changing the prescription.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Transpose sphere/cylinder notation without changing the prescription. Dioptres and degrees; axis 0–180. Does not diagnose or generate prescriptions.

    Why it is in this group

    • The name "get_optical_topic" says "get": a word for reading.
    Description, as the server wrote it
    Read a public optical topic by stable ID with references, related topics and limitations.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • search_optical_knowledgeSearch public optical education in Portuguese or English.No findings

    Why it is in this group

    • The name "search_optical_knowledge" says "search": a word for reading.
    Description, as the server wrote it
    Search public optical education in Portuguese or English. Returns source excerpts, not medical advice or customer records.

    Annotations the server declares

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
