Acceptance checklist

  • The final answer addresses the written brief without silently changing the scope.
  • Material factual claims are traceable to the supplied sources or clearly labelled as inference.
  • The spreadsheet, document or presentation is editable rather than a flattened demonstration artefact.
  • A reviewer can identify what the agent changed, which tools it used and where human approval remains required.
  • The result needs no more repair time than the pre-agreed acceptance threshold.

Do not buy yet

Avoid this option when

  • ×The task is an ordinary chat request rather than a repeatable workflow.

Where are prompts, files, logs and generated artefacts stored, and how long are they retained?
Are tool calls, connector activity, failures and human approvals visible in an audit trail?
