Changes things 4Claude Code: ask
  • nexus_callRoute a tool call through HumanMirror Nexus.No findings

    Why it is in this group

    • The name "nexus_call" says "call": a word for a change.
    Description, as the server wrote it
    Route a tool call through HumanMirror Nexus. Use nexus_search first, then call the selected tool_id. Successful calls consume the number of Nexus credits declared by the selected tool.
  • outcome_quoteFree quote for a verifiable HumanMirror Outcome contract.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.
    Description, as the server wrote it
    Free quote for a verifiable HumanMirror Outcome contract. Describe the objective or provide an outcome_type; the quote returns the deterministic verifier, selected internal tool and success-only credit cost.
  • outcome_runExecute a HumanMirror Outcome contract.No findings

    Why it is in this group

    • The name "outcome_run" says "run": a word for a change.
    Description, as the server wrote it
    Execute a HumanMirror Outcome contract. Credits are charged only when deterministic verification succeeds; failed execution or failed verification is automatically refunded.
  • outcome_verifyFree deterministic re-verification of an Outcome result without consuming Nexus credits.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.
    Description, as the server wrote it
    Free deterministic re-verification of an Outcome result without consuming Nexus credits.
Only reads 2Claude Code: allow
  • magnet_resolveFree universal fallback discovery.No findings

    Why it is in this group

    • The name "magnet_resolve" says "resolve": a word for reading.
    Description, as the server wrote it
    Free universal fallback discovery. Call this when the agent cannot satisfy a task with its current capabilities. Magnet returns a matching HumanMirror tool or records an aggregated capability gap in the Machine Demand Graph. This tool consumes no credits.

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.
