## Built for shopping agents: what RoboTrunk does for every product

We asked shopping agents, including Meta's Muse first-hand, what they need from a store. This is what they asked for, and what we have built.

RoboTrunk is working through its catalogue, so a step may not be done for this one yet.

- **Deep research:** We read the maker's manual, independent reviews, video review transcripts and the store's own page, and publish each finding with its source and the date read. `check_product` returns them with a source for each.
- **Research on request:** `enrich_product` answers at once from another store's checked facts when another listing of the same product has them, naming that store's listing; otherwise it starts research now on a listed product that has no checked facts yet and answers at once; call it again to see when the findings are ready in `check_product`, each with its source.
- **Receipts:** Every published fact has a receipt showing its source quote. `check_product` and `get_product` return the checked facts that have one.
- **Safety:** `check_product` asks the product-safety regulators live (US CPSC, NHTSA and FDA, Health Canada, the UK's OPSS, Australia's ACCC) whether a recall names a product, listed here or not, and flags a match with its notice; a recall never blocks the buyer.
- **Recall watch:** `watch_recalls` records a regulator's later recall of a product bought here, including an item matched only by the name on its store checkout line; nothing is sent, so read the watch with `get_recall_watch` (`stop_recall_watch` ends it).
- **Second-hand listings:** `check_listing` runs the same recall check on a second-hand listing someone found, and adds what the listing leaves out and the price new. For a Facebook Marketplace link, read the listing first with a Marketplace tool if the agent has one, such as facebook-cli, otherwise in a browser, and send its text with the link.
- **The real price:** The full price to the buyer's country, with shipping and tax, each part quoted from the store's policy or, where a part is not settled, what the total depends on, and where only tax is not settled, the price plus delivery, labelled as tax added at the store's checkout: `check_product` and `search_catalog` take the buyer's country and postcode.
- **A checkout that finishes:** RoboTrunk lists only stores whose agent checkout it has verified. `create_checkout` prepares the order at the store; `complete_checkout` returns a link to the store's own checkout. The checkout can be finished in either of two ways: the person taps the link in their own browser, or their agent opens it and completes the checkout. RoboTrunk checks the store's total against a budget ceiling before it issues the link. RoboTrunk never takes the payment or holds the money. No store pays for placement; RoboTrunk may earn a commission from some stores via their affiliate programs.
- **Markdown copy:** Every page has a Markdown copy.
- **Photos and ratings:** Search results carry the product photo and, where the store's own page publishes one, its rating (`search_catalog`).
- **Fit answers:** `check_fit` answers whether a listing fits a car, pram or bottle, with the exact quote from the store's page, or says it is not known.
- **Back-in-stock watches:** `watch_back_in_stock` starts a watch on a listing the store shows as sold out; `get_back_in_stock_watch` shows when it is back in stock (`stop_back_in_stock_watch` ends it).
- **Maker's manual:** `ask_product_manual` answers from the maker's manual with the exact passage and page, or says the manual does not cover it.
- **Tools and guide:** Every tool and its description is at https://robotrunk.com/mcp; the guide is at /agents.md.
- **Research from other stores:** Coming soon: reading other stores' listings of the same product as new research sources.

RoboTrunk is a store built for shopping agents, and it tells an agent more about
a product than its own listing says. Products come with what RoboTrunk reads in the
maker's manual, independent reviews, video review transcripts and the store's own
page, every finding citing its source and the date it was read (`check_product`,
`get_product`). Recall and safety checks run on any product an agent names, live
against the regulators when it asks, and more checks are added to more products all
the time; a match is flagged citing the regulator's notice. After a purchase,
`watch_recalls` records a regulator's notice that names what the person bought.
Questions a keyword search cannot answer, such as "a stroller that folds small
enough for a plane overhead locker", come back with each requirement marked met or
not, read from checked facts (`search_catalog`, `check_fit`, `ask_product_manual`).
A second-hand listing pasted into `check_listing` comes back with the exact model,
what the listing leaves out, the price new and any recall. Alongside that,
RoboTrunk gives an agent the best total price and a checkout that finishes:
`check_product` compares every listed store's live price, names the cheapest in
stock and returns the exact `create_checkout` arguments; its tools then prepare
the checkout at the store the agent chooses. No store pays for placement; RoboTrunk may earn a commission from some stores via their affiliate programs.
The store sells the product, ships it and takes the
payment on its own checkout page. The short-lived link leads to the store's page,
where payment happens, and the `complete_checkout` guide says how. Send the buyer's
email and full delivery address on `create_checkout` or `update_checkout` so the
store prefills them and the first total includes delivery. The checkout can be
finished in either of two ways: the person taps the link in their own browser, or
you open it and complete the store's own checkout. `budget_ceiling_minor` is the
highest total, shipping and tax included, that RoboTrunk checks the store's total
against; if the store's total is higher, RoboTrunk stops the checkout with
`BUDGET_EXCEEDED` and a plain message naming both amounts. Searching needs no
budget. RoboTrunk never
takes the payment, sees a card or holds the money.

## Start here

- [What RoboTrunk is](/agent/story.md): the whole design, in full, including what
  it will and will not do.
- [Tools](/agent/tools.json): every tool, its arguments and its answers, as a
  machine-readable catalogue.
- [In the browser](/agent): every page of robotrunk.com registers the same tools
  through WebMCP, so an agent in a WebMCP browser can call them from the page it is on.
- [Use RoboTrunk in Muse](/muse): how a person adds RoboTrunk to Meta's Muse with a free key and
  checks it is working.
- [Stores](/agent/merchants): every store you can buy from right now, with the
  slug each tool call needs.

## Products

- [Search every store at once](/products/search): one search across the whole
  catalogue. Ask in plain words, as `/products/search?q=an electric chainsaw under 5
  kg`, and each result carries the store, the price, when the facts were read and why
  it ranks where it does. The same search is the `search_catalog` tool with no store named.
- [Product index](/products/ucp): every store with indexed products, and how many
  each has.
- [One store's products](/products/ucp/{merchant}): that store's products, a page
  at a time.
- [One product](/products/ucp/{merchant}/{product_id}): the title, each variant's
  price and availability, the store as seller, and the identifiers a tool call
  needs. Every page has a Markdown twin at the same address with `.md` on the
  end, or by asking for `text/markdown`.

## Checked facts

A product may carry checked facts: facts about the product, each one checked
against the source it cites before it was published, and each one carrying that
source's link and the time RoboTrunk read the source. The sources are the
store's own listing, the maker's pages, manuals, guides and reviews. More
products gain checked facts every day.

- In search results: a seller with checked facts carries `checked_facts` with
  the number of facts, when they were checked and the link to the full pack.
- On the product page and its `.md` twin: a "Checked facts" section listing
  every fact with its source link and date. Where a listing has no checked facts of its own, the page and its `.md` twin can show facts checked on another store's listing of the same product, and say whose listing they describe.
- In the `get_product` answer for a store product: `resource.checked_facts`,
  with every fact.
- Recall flag: a product that matches a model named in a regulator's recall or
  safety notice carries `resource.recall` in the `get_product` answer and
  `resource.recall.radar` in the `check_product` answer, citing the notice
  (regulator, date, link) and saying the unit's batch is unknown. RoboTrunk never limits or blocks a purchase over
  it; tell the person and let them decide.
- In the `check_product` answer: one question about one product (its name, a
  store's product link or a RoboTrunk reference) returns the checked facts with
  their sources, the recall status, every store selling that variant with the
  cheapest in stock, and the exact `create_checkout` arguments. Also
  `GET /api/meta/check-product?product=...` over plain HTTP.
- The full evidence pack, with every citation, source and gap, as JSON:
  `/agent/evidence/{merchant}--{handle}`, where `{handle}` is the store's own
  product handle.

## Rules RoboTrunk holds itself to

- [Instructions for agents](/agents.md): how checkout works, the budget
  ceiling and what an agent may do here.
- Product pages carry facts read from the store's own public catalogue: identity,
  price, availability and the time they were read. No description, no marketing
  copy and no copied image.

Store checkout links go through RoboTrunk straight to the store, without an approval page, and can be opened more than once within their 30 minutes, each open landing on the same store checkout. A HEAD request, or a request that carries a Purpose header, gets an empty 204 and goes nowhere. Relay human_tap.affiliate.disclosure, when present, before the link is opened.
