Changes things 1Claude Code: ask
  • arclight_city_picksA small curated set of events worth going to in a city over the next few days, chosen for variety rather than raw recency.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
    A small curated set of events worth going to in a city over the next few days, chosen for variety rather than raw recency. Use when someone asks what is worth doing rather than for an exhaustive list. Read-only.

    • The name "arclight_search_events" says "search": a word for reading.
    Description, as the server wrote it
    Search real, upcoming events in a city, optionally narrowed to a topic and timeframe. Every event is aggregated from a live source (Luma, Ticketmaster, SeatGeek, Skiddle, confs.tech and others) and links back to it — Arclight never invents listings and holds no tickets. Read-only. Returns paginated results with has_more/next_offset.

    • title: Search live events by city
    • readOnlyHint: true
    • destructiveHint: false

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.
