Changes things 7Claude Code: ask
  • trial_fork_pairFork a checkpoint-paired assignment for one task (blinded arms A/B).No findings

    Why it is in this group

    • The name "trial_fork_pair" says "fork": a word for a change.
    Description, as the server wrote it
    Fork a checkpoint-paired assignment for one task (blinded arms A/B).
  • trial_register_protocolRegister a hash-bound trial protocol; twins fork from the identical checkpoint, exactly one registered variable may differ.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
    Register a hash-bound trial protocol; twins fork from the identical checkpoint, exactly one registered variable may differ.
  • trial_run_pairRun one pair with the deterministic scripted agent and score blind.No findings

    Why it is in this group

    • The name "trial_run_pair" says "run": a word for a change.
    Description, as the server wrote it
    Run one pair with the deterministic scripted agent and score blind. $0.25/pair, first 10 free once per operator.
  • trial_scoreAlias of trial_submit_outputs (blinded scoring).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
    Alias of trial_submit_outputs (blinded scoring).
  • trial_submit_outputsSubmit the operator twins' outputs for one pair; blinded deterministic scoring.No findings

    Why it is in this group

    • The name "trial_submit_outputs" says "submit": a word for a change.
    Description, as the server wrote it
    Submit the operator twins' outputs for one pair; blinded deterministic scoring. $0.25/pair, first 10 free once per operator.
  • trial_unblindUnblind after the verdict; hashed signed receipt covering every pair.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
    Unblind after the verdict; hashed signed receipt covering every pair.
  • trial_verdictTrial verdict under the enforced stopping rule.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
    Trial verdict under the enforced stopping rule.

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.
