Interviews a Sillage customer to extract and EXPAND their go-to-market context — what they sell, who buys, and the buying signals that matter — then proposes optimized keywords, job titles, and agents most users would never think of, and writes a precise persona through the Sillage MCP. Use when setting up a workspace, when targeting is vague or thin, or when agents and content underperform because the persona is weak. Use when you hear: "grill me", "set up my workspace", "help me target", "build my persona", "what keywords should I use", "expand my job titles", "who should I track", "I don't know what to put".
