What they did
1) Create a Claude Code project for the renovation and organize its emails, invoices, bank records and completed-work notes. Resolve gaps with human guidance before comparing prices. 2) Add dated estimates and retain earlier versions. Ask the agent to compare equipment, repairs, exclusions and warranty conditions across suppliers and revisions. 3) Investigate mismatches: in this case the diagnosis concerned ductwork, but the initial quotes priced equipment and excluded existing ducts. 4) Send both contractors the same questions yourself: separately price repairs, identify the matched equipment rating, state exclusions and site duration, and quote comparable equipment tiers. Keep competing prices private. 5) Add the replies, rerun the comparison, and personally select and sign the final scope.

Worth knowing
He personally handled visits, calls, messages and signing. The agent maintained records and comparisons; it did not negotiate with contractors.
