2 checks 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.

    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.

      inputSchema.properties.fact.properties.source.description: "Stable credential-free absolute HTTP(S) source URL. Track..."

      What this check looks for
    Description, as the server wrote it
    Cost preflight before repeated paid or slow source-backed validation, especially across an agent fleet. Use before paid web search, metered scraping, browser/extraction, rate-limited APIs or multi-step validation when the caller already has a known value. Returns SAME_OBSERVED, CHANGED_OBSERVED, CONTESTED, STALE or UNKNOWN. Only SAME_OBSERVED can be considered for caller-policy-gated reuse; every other status requires normal authoritative validation before OBSERVE. SeenRelay never browses or verifies externally.

      What this check looks for
    Description, as the server wrote it
    After independently performing a source-backed validation, deposit the observed result for later CHECKs. Returns accepted=true when a new observation is stored or deduplicated=true for a recognized retry/recent duplicate. Never OBSERVE hearsay. Optional Ed25519 proof establishes key possession and continuity, not truth or real-world independence.

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.
