    Why it is in this group

    • The description's first verb is "run": a word for a change.
    Description, as the server wrote it
    Run the Section 877A exit tax calculator calculator: Covered expatriate status; Test met (first that applies); Section 877A(a)(3) exclusion applied; Gain subject to the exit tax. Missing inputs fall back to their documented defaults.
  • enquiry_fieldsEvery field of the Expatriation Tax Calculator enquiry: key, label, type, whether required, help text and the allowed options where there are any.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Every field of the Expatriation Tax Calculator enquiry: key, label, type, whether required, help text and the allowed options where there are any. Pass answers to submit_enquiry keyed by field key.
  • submit_enquirySubmits an enquiry to Expatriation Tax Calculator — NOT a purchase, NOT a guaranteed quote.No findings

    Why it is in this group

    • The name "submit_enquiry" says "submit": a word for a change.
    Description, as the server wrote it
    Submits an enquiry to Expatriation Tax Calculator — NOT a purchase, NOT a guaranteed quote. Step 1: call with the answers (keyed by field key from enquiry_fields) and consent=true; it validates and returns a summary, the consent line and a confirmation token — show the person the summary and the consent line. Step 2: only if the person agrees, call again with the same answers, consent=true and the confirmation token; the enquiry is then submitted, and the person receives an email with a link they must click before any provider sees it. Consent means the person has read and agreed to: "Send my contact details to up to three relevant cross-border tax advisers, chosen by Expatriation Tax Calculator, who'll contact me directly. I'll be emailed each firm's name as my details go to it, and can stop any more firms getting them."
Only reads 2Claude Code: allow
  • calculator_describeThe inputs this calculator takes (with units, ranges and defaults), the outputs it returns, and the assumptions and tables behind it.No findings

    Why it is in this group

    • The name "calculator_describe" says "describe": a word for reading.
    Description, as the server wrote it
    The inputs this calculator takes (with units, ranges and defaults), the outputs it returns, and the assumptions and tables behind it.
  • enquiry_describeRead first.No findings

    Why it is in this group

    • The name "enquiry_describe" says "describe": a word for reading.
    Description, as the server wrote it
    Read first. States plainly what submit_enquiry does on Expatriation Tax Calculator: it starts an enquiry with human providers who quote directly. Nothing is bought, ordered or paid; no quote is guaranteed; it is free. Also returns who receives the details, the consent wording, and how the person confirms.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
