Tools
| Tool | Description | Behaviour |
|---|---|---|
| compare_weight_loss_medications | Side-by-side comparison of the three GLP weight-loss medications Deer Supply sells (Semaglutide, Tirzepatide, Retatrutide): mechanism, generation, the landmark trial's average weight loss, maintenance dose, today's starting price and lowest price per mg in CAD. Use this when someone is choosing a weight-loss option. | Read-only |
| create_cart_link | A deer.supply link that opens the cart with these items already in it, for the person to review and check out themselves (they enter their own delivery details and payment). Agents cannot place orders. | Read-only |
| delivery_estimate | When an order placed now would ship and arrive, for a Canadian postal code, using the dates Deer quotes on its product pages (orders by noon Eastern ship that weekday; pens travel on the fastest service). | Read-only |
| estimate_weight_loss | What the clinical trials averaged for someone at a given starting weight, per medication, at 6, 12 and 18 months, using the same curves as deer.supply/calculator. These are trial averages, not a prediction for any one person. | Read-only |
| get_help | Answers from Deer Supply's FAQ (shipping, storage, payment, using the pens, eligibility, returns) plus links to its policies. Pass the question; leave it empty for the whole FAQ. | Read-only |
| get_lab_results | Third-party lab (COA) reports Deer Supply publishes per product size. Optional product_id. | Read-only |
| get_my_account | Requires signing in with a Deer account. A plain-language summary of the signed-in customer's Deer account: their name, orders with status and tracking, store credit and rewards, and (when health access was granted) each health profile's weigh-ins, plan and side effects. The same picture the store's own assistant has. Start here. | Read-only |
| get_my_health | Requires signing in with a Deer account. Each health profile on the account (one sign-in can chart several people): its id (needed to log anything), recent weigh-ins in pounds and the trend, the treatment plan (medication, week, current dose, next injection, upcoming dose steps), side effects with their ids, reminder settings and the weigh-in reward. | Read-only |
| get_product | Everything Deer Supply publishes about one product: what it is, sizes and prices, the published dosing schedule, what is in the box, lab (COA) reports, and the related FAQ answers. product_id comes from search_products (e.g. 'retatrutide'). | Read-only |
| get_store_info | Who Deer Supply is and how buying works: what it sells, where it ships, payment methods accepted right now, shipping costs, the money-back policy, lab testing, and how to reach a person. | Read-only |
| get_trust_report | Evidence about Deer Supply as a business, from its own records, aggregated and de-identified: how many paid orders it has shipped and delivered (with carrier tracking), dispatch and transit times, refunds, weight change among customers who chart their weight on a treatment plan (median and shares, groups under 10 people withheld), third-party lab reports, and moderated reviews. Each figure states its sample size and method. | Read-only |
| import_weights | Requires signing in with a Deer account. Add many past weigh-ins at once (from a scale app, a spreadsheet, a photo the person shared). Days already logged are skipped. Show the person the list and get their OK first. | Changes data |
| list_my_orders | Requires signing in with a Deer account. The signed-in customer's orders, newest first: number, date, status, total, items, tracking number and expected arrival. | Read-only |
| log_weight | Requires signing in with a Deer account. Record a weigh-in on one of the customer's health profiles. Confirm the number with the person first. | Changes data |
| quote_cart | Price a cart exactly as Deer Supply's checkout would: line prices with any sale or quantity break, an optional coupon code, shipping and the total in CAD, plus a delivery estimate when a Canadian postal code is given. variant_id values come from search_products. Nothing is reserved or ordered. | Read-only |
| report_side_effect | Requires signing in with a Deer account. Send a side effect to the customer's care team on one profile. If it sounds severe, tell the person to get medical help right away (call 911 or go to an emergency department) as well; this report is not an emergency channel. | Changes data |
| resolve_side_effect | Requires signing in with a Deer account. Mark one of the profile's open side effects as resolved (side_effect_id from get_my_health). Reopening one is the care team's job. | Changes data |
| search_products | Search Deer Supply's catalog (Canada). Weight loss: Retatrutide, Tirzepatide and Semaglutide as pre-filled, ready-to-use pens; also recovery products and ancillary capsules. Returns each product with its sizes, today's price in CAD (sales included), price per mg, quantity breaks, stock and links. Call with no arguments to list everything. | Read-only |
| set_health_emails | Requires signing in with a Deer account. Turn a profile's weigh-in reminder emails and/or reorder alert emails on or off. | Changes data |
| track_order | Status of a Deer Supply order, given its order number AND the email it was placed with (the same check as deer.supply/track). Returns the status, dates, items and tracking number. Never returns addresses or payment details. | Read-only |
