Tools & capabilities
HerStack tools 5
search_guidanceCall 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) 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.get_topic_guidanceCall 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).recommend_supplementsCall 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.get_evidenceCall 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.get_product_detailsCall 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.
