The moment
A prospect replies asking whether they are talking to a real person.
What the harness does
The conversation comes straight to you. The harness never answers that question itself, and sends a single reminder if you have not replied after a day.
Tools and API

Drive the harness from your own systems over REST, or from any AI client over MCP. Every call is validated and written to the journal.
