B2B Sales Agent — Full System Prompt

A complete, config-driven system prompt for a Claude-powered B2B sales agent: layered SPIN-style discovery, combined BANT + MEDDIC scorecard with a hard demo-gate rule, a full objection playbook (acknowledge, isolate, reframe, verify), advancing discipline that ends every conversation with a calendar-confirmed next step, and a structured CRM update block emitted after every interaction. Fill the CONFIG block with your product, ICP, and ACV — deploy as a call copilot, SDR email agent, or inbound qualifier.
