About

Design persistent AI agent personas with distinct voices, durable memory, and clear operating rules. Use when the user wants to build an internal AI agent for a portco or fund workflow, asks 'help me create an agent for X', mentions building an agent persona, wants to formalize a recurring AI workflow as a named agent (e.g. 'Ada the DD analyst'), or asks how to design agents that don't sound generic. Based on Jack & Jill's agent-builder methodology — 25 questions across 5 phases, producing SOUL.md (personality), AGENTS.md (operating manual), MEMORY.md (cross-session knowledge), and BOOTSTRAP.md (first-boot orientation).

Use cases: design, productivity, agent-building
