    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
    Which vitamins and minerals interact with given medications (generic or brand names, e.g. "warfarin", "Synthroid") or conditions, per the NIH Office of Dietary Supplements fact sheets, with timing advice (e.g. take levothyroxine 4 hours apart from calcium). No product list needed; to check an actual stack, pass medications to stack_analyze instead. Not exhaustive.

    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
    FDA recalls and adverse event reports (CAERS) for one supplement, from openFDA. Give a product name, barcode, DSLD ID, or brand and name. Recalls are listed only when they carry the barcode or the brand and every product-name word; adverse event reports are counted with their most common reactions. Reports do not show that a product caused an event.

    Description, as the server wrote it
    Look up a supplement by the UPC/EAN barcode printed on the bottle. Returns the newest matching DSLD label, normalized, and any older versions.

    Why it is in this group

    • The name "stack_analyze" says "analyze": a word for reading.
    Description, as the server wrote it
    Check a list of dietary supplements for a person: per-nutrient daily totals against NIH upper limits (UL) and RDA/AI, which products overlap, what each UL protects against, and single-product changes that would bring an above-UL nutrient back under it. Products can be given as names ("Centrum Silver Women 50+"), barcodes, DSLD IDs, or custom ingredient lists; optional candidates are evaluated as additions. Pass the person's medications and conditions (smoker, kidney_disease, hemochromatosis, lab_test_soon, cancer_treatment) to check them against the interactions in the NIH fact sheets. Returns agent_summary (plain sentences to relay), resolutions, suggestions, interactions, nutrient_totals and data_gaps. Label data only; food is included only with diet "typical".

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.
