1 check matched something in the tool definitions. No finding is not a safety guarantee. How the checks work.

Findings

Matches of fixed checks, with the text they matched.

1 warn
  • Warnbest_day

    The server marks "best_day" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

    Matched text

    annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.

Can't be undone 1Claude Code: ask
  • best_dayWhich day in a window (max 7 days) is best for an activity at a destination — a spot, a region, or lat+lon with a radius — and why, versus the runner-up.1 finding

    Why it is in this group

    • The input addresses people (input.to): what it sends cannot be taken back.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    • Warn

      The server marks "best_day" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

      What this check looks for
    Description, as the server wrote it
    Which day in a window (max 7 days) is best for an activity at a destination — a spot, a region, or lat+lon with a radius — and why, versus the runner-up. Returns every day's best score, confidence, caveats and a KaiCast spot card for the winner. Free during early access.

Changes things 1Claude Code: ask
  • recommend_spotRanked top picks (max 5) for an activity in one area on one day — by region id, or lat+lon with a radius.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
    Ranked top picks (max 5) for an activity in one area on one day — by region id, or lat+lon with a radius. Each pick has the best daylight window, why (from the published conditions), a confidence score with its factors, caveats, and a KaiCast spot card. Returns status "not_covered" / "conditions_only" / "activity_not_modeled" honestly instead of guessing. Activities: snorkel (native model), dive, freedive, spearfish (proxy model; spots in water closed to spearfishing are excluded), surf (not modeled). Free during early access.

    • destructiveHint: false
    • idempotentHint: true

  • get_conditionsFacts for ONE covered spot over up to 7 days: 3-hour forecast periods with condition score (0-100) and rating, water visibility (ft), swell height/period/direction, wind, tide stat…No findings

    Why it is in this group

    • The name "get_conditions" says "get": a word for reading.
    Description, as the server wrote it
    Facts for ONE covered spot over up to 7 days: 3-hour forecast periods with condition score (0-100) and rating, water visibility (ft), swell height/period/direction, wind, tide state and height, water temperature, plus tide events and data quality. Pass a spot id, or lat+lon to use the nearest covered spot within 30 km. Free.

    Annotations the server declares

    • title: Get ocean conditions
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • list_coverageWhich regions and spots KaiCast covers, and whether each region supports ranked decisions (spot picks and best-day answers) or facts only.No findings

    Why it is in this group

    • The name "list_coverage" says "list": a word for reading.
    Description, as the server wrote it
    Which regions and spots KaiCast covers, and whether each region supports ranked decisions (spot picks and best-day answers) or facts only. Also lists supported activities and how directly each is modeled. Anywhere not listed is not covered. Free.

    Annotations the server declares

    • title: List KaiCast coverage
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: 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.
