Ask for the receipt: make your agent write down everything it does

An agent that sends emails and books appointments should leave a paper trail. Otherwise the first dispute is your word against a chatbot's.

When a new hire issues a refund, you expect a note in the customer file. An agent that sends emails, books appointments or edits your CRM deserves the same rule. Skip it, and the day a customer says "your bot promised me 20% off", you have nothing to check. Just their screenshot and a shrug.

  1. Decide what needs a receipt. Anything that leaves the building or changes a record: a sent message, a booking, a refund, a price quote. Reading and summarising can go unlogged.
  2. Keep it to one line and five fields. When, what, for whom, why (the request or rule that triggered it) and which record it touched. A shared spreadsheet or a private Telegram channel is plenty. Nobody needs a dashboard for this.
  3. Write the line before the action. If the agent crashes halfway through, you can still see what it meant to do.
  4. Read 20 receipts every Friday. Ten minutes with a coffee. The odd ones jump out fast: a discount offered twice, a booking made at 3am, the same customer emailed four times.
  5. Add an "undo" column. Next to each type of action, write how you would reverse it. If the answer is "we can't", that action goes back to draft-then-send.

On this site every new newsletter signup lands in my Telegram as a one-line note. It's the cheapest audit trail there is. An agent that keeps no log is a colleague who never writes anything down: charming right up to the first argument.
