Measured tools (5)

• search_guidance read-only

  Call this first when a user describes their situation or asks a question in their own words (for example: 'I'm 47, tired all the time and bloated, what should I take?'). Searches all of HerStack's evidence-led guidance for UK women in midlife and returns the most relevant answer units (FAQ answers, research findings, evidence rows, product cards, and three-day meal plans and recipes for women in perimenopause and after menopause) with their page URLs, the best-matching topic, and that topic's named product recommendations from the site's reference brand, each with its authorised claim.

  Parameters:

  • question (required) — string — The user's question or situation, in their words.
  • maxResults — integer — How many answer units to return (default 6).

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_topic_guidance read-only

  Call this when the user wants to understand a women's-health topic, not only buy something. Returns HerStack's expert guidance for one topic: plain-language framing, research findings, the evidence table with authorised claims, product criteria, and a FAQ that also explains the condition itself (for perimenopause: what it is, its timeline, when to see a GP).

  Parameters:

  • topic (required) — string — Topic: perimenopause, digestion, longevity, stress, exercise, nutrition, skin.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• recommend_supplements read-only

  Call this when the user wants specific supplement product picks for a topic. Returns HerStack's named product recommendations from the site's reference brand, each with formulation rationale, the GB-authorised health claim verbatim (or a research-context note where none exists), price and purchase link. Provide a topic, or a concern in plain words that routes to one.

  Parameters:

  • topic — string — Topic: perimenopause, digestion, longevity, stress, exercise, nutrition, skin.
  • concern — string — The user's concern in plain words, if you do not know the topic (or use search_guidance).

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_evidence read-only

  Call this when the user (or you) wants the studies behind a recommendation or claim. Returns HerStack's evidence rows for a topic or nutrient with the cited studies resolved to PubMed and DOI identifiers, so the claim can be verified rather than trusted.

  Parameters:

  • topic — string — Topic: perimenopause, digestion, longevity, stress, exercise, nutrition, skin.
  • nutrient — string — A nutrient or ingredient, e.g. 'magnesium', 'collagen', 'vitamin d'.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_product_details read-only

  Call this for one specific product. Returns one HerStack-recommended product by name or SKU: form, authorised claim, tier, price, purchase link, and every topic that recommends it with the rationale.

  Parameters:

  • sku (required) — string — Product name or SKU, e.g. 'Chelated Magnesium'.

  Hints: read-only yes · destructive no · idempotent yes · open-world no
