      What this check looks for
    Description, as the server wrote it
    Use this when the user needs a date N working days from another date: delivery and shipping estimates, payment or settlement terms, notice periods, SLA and deadline questions. Skips weekends and the public holidays of the country or region, reports exactly which days were skipped, and flags any date in the range that independent sources disagree about.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true
  • check_business_dayUse this when the user asks whether one specific date is a working day, a public holiday, or whether businesses and banks are open.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.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Use this when the user asks whether one specific date is a working day, a public holiday, or whether businesses and banks are open. Names the holiday if there is one, and reports whether independent holiday sources agree on that date.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true
  • cross_check_holidaysUse this when accuracy matters more than speed, or when the user questions whether a holiday date is right: contracts, payroll, settlement, compliance deadlines.No findings

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Use this when accuracy matters more than speed, or when the user questions whether a holiday date is right: contracts, payroll, settlement, compliance deadlines. Compares the national holiday list for a country and year across three independent providers and reports exactly where they agree and disagree, rather than picking one.

    Why it is in this group

    • The name "list_public_holidays" says "list": a word for reading.
    Description, as the server wrote it
    Use this when the user asks what the public holidays are in a country or region for a given year, when a particular holiday falls, or how many holidays a year has. Covers 200+ countries with state and province detail. Do not use it for working-day arithmetic; use add_business_days for that.

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.
