Definition
A harness organises calls, supplies context, manages task state and runs tools within permissions. Returned observations can trigger another step or a check. MCP specifies standardised exchanges; it is not a complete execution harness.
Assumptions and notation
Describe the model, execution controller, tools and verifiers separately. Check observed outcomes, not only the assistant’s account.
Limits of interpretation
A persuasive explanation does not prove a result correct. Autonomy depends on access, success criteria, stopping conditions and recovery. Evaluate the complete system on the intended task.
