Contract review and diligence are exactly the long, careful runs agents are good at, and exactly where unaccountable AI is unacceptable. Handbell keeps a lawyer's name on every judgment.
An agent works through the MSA clause by clause over the afternoon. Two associates watch; one owns the run. Every suggested edit is attributed to the agent, separate from human edits, so accepting and rejecting never blur who wrote what.
A data-room review runs for three days. The Friday associate hands the run to the Sunday associate, who accepts it with the full history intact. The partner drops in Monday morning to the flagged-clause list, not to a scroll of chat.
The agent can draft anything; it can send nothing. External communication rings the lawyer who holds that permission, and the approval, the version, and the timestamp all land in a record built for the day someone asks who authorized this.
An agent cannot appear before the bar. The lawyer who supervised it can, with the log to show for it.
