Changes things 2Claude Code: ask
  • check_addressUse when someone asks what applies to a rented home at a postcode in England.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 when someone asks what applies to a rented home at a postcode in England. Returns whether a council property licence is needed for the household type, the council's licensing schemes, the planned landlord register window, flood zone and conservation area, each with its source, and councilPage, Lettance's page for that council. Read-only. England only; a council we have not researched yet says so instead of guessing. Information, not legal advice.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Use when someone asks about a council's licensing schemes in England. Returns every scheme for the council with its wards, dates, fees and council sources. Pass a slug such as 'southwark' or a name such as 'Birmingham'. Read-only. A council we have not researched yet returns researched: false with its region and landlord register window.

    Description, as the server wrote it

    Why it is in this group

    • The name "search_rules" says "search": a word for reading.
    Description, as the server wrote it
    Use for general questions about what private landlords in England must do, such as gas safety, deposits, EPC ratings, smoke alarms or notices. Searches Lettance's catalogue of rules, each cited to legislation.gov.uk or GOV.UK, and returns matching rule ids with summaries. Use get_rule for one rule's full detail. Read-only.

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.
