### Tool changes

- 2026-11-03 `open_invitation` changed (description)
  - before: Open an invitation a business sent the user, using the invitation code from their message (8 letters and digits, e.g. K7Q2M8XD). Returns the business, what the invitation is about, its contact person and its current shareable documents with download links. Works before the user signs in.
  - after: Open an invitation a business sent the user, using the invitation code from their message (8 letters and digits, e.g. K7Q2M8XD). Returns the business, what the invitation is about, its contact person and its current public documents with download links. Works before the user signs in. Documents shared only with the invited address open after that address confirms the invitation (the claim link in the result) and signs in.

## Tools (8)

- `answer_questions`: Call this for any question about a business in list_my_businesses, even when notes, memory or a web page seem to answer it: only this tool returns the business's approved answers. Look up a business's approved answers: questionnaire questions (supplier, compliance, security or due-diligence questionnaires) and other questions about the business, its products, terms and prices. For each question it returns the closest approved answers with their source, approval date and similarity, or says that none was found; a question without one also gets the passages of the business's current documents that match it, quoted with document, version and page (not approved answers: say so if you use one, and cite it). You write the reply from these. Each answer was approved by the business for the question shown with it, so check that it fits before using it. Only answers the business approved for the same question count; a question without one is reported as unanswered, with at most one approved answer to a different question shown as possibly related. To get an unanswered question to the business, call ask_business. Without business_id or business it searches every business the user has and names the business next to each answer. When the user writes in another language than the business's material (most businesses write in English), pass each question in the business's language too, as a second question, so it matches; then reply to the user in their own language.
- `ask_business`: Send questions to one business's contact person, for example the questions answer_questions could not answer. Nothing is sent on the first call: it returns a preview of exactly what would go to the contact person, and a confirmation code. Show the whole preview to the user; only if they agree, call again with the same business and confirm set to the code. Then Avenbridge emails the questions to the contact (with the user's email as reply-to) and sends the user a copy; the answers come back through status and, once given, through answer_questions. The same questions sent again within a day are not sent twice. Needs business_id (or business) when the user has more than one business.
- `get_documents`: Get the current versions of a business's shareable documents: certificates (ISO 9001 and others), compliance declarations (RoHS, REACH, conflict minerals), safety data sheets, data sheets and test reports. Filter by part number and/or document type. Returns version, issue and expiry dates, and a download link that works for 15 minutes. Without business_id or business it lists the documents of every business the user has, grouped by business.
- `list_my_businesses`: List the businesses (suppliers) that share documents and approved answers with this user through Avenbridge: their ids, counts and any context from their invitation, such as a shipment or part number. Call it first when you do not know which business the user means or need a business_id.
- `open_invitation`: Open an invitation a business sent the user, using the invitation code from their message (8 letters and digits, e.g. K7Q2M8XD). Returns the business, what the invitation is about, its contact person and its current public documents with download links. Works before the user signs in. Documents shared only with the invited address open after that address confirms the invitation (the claim link in the result) and signs in.
- `request`: Send a request to one business: anything the user wants that business to do. Each business lists the kinds of request it takes (list_my_businesses and the server instructions; by default quote, sample, document, reschedule, complaint, other). When the user wants a call or meeting and the business lists "call", use kind call: the user gets the business's booking page at once and picks a time there. Otherwise nothing is sent on the first call: it returns a preview of exactly what would go to the business's contact person, and a confirmation code. Show the whole preview to the user; only if they agree, call again with the same business and confirm set to the code. Then Avenbridge emails the request to the contact (with the user's email as reply-to) and sends the user a copy; the reply shows up in `status`. The same request sent again within a day is not sent twice. Before a quote or sample request, ask the user for the items in the business's request checklist (shown by list_my_businesses and in the server instructions) so the request arrives complete, and put them in details.
- `share`: Give the user a page where they attach files for a business: drawings, filled forms, photos of a defect, specifications. Files cannot travel through this tool, so the page is the way; the link works for 15 minutes. With case_id the files attach to that request; without one, the page sends them to the business as a new request.
- `status`: The user's open and recent requests (questions, quotes, samples, documents, complaints) with one business or with all of them: what was asked, when, where it stands, and the business's reply when there is one. Use it when the user asks whether a business has answered or what is pending.
