The Enneagram identifies nine distinct personality types, each defined by a core desire (what the type most fundamentally wants), a core fear (what it most dreads), and a characteristic set of strengths and defensive patterns. No type is superior to another — each brings genuine gifts and genuine blind spots.

The Enneagram Types and AgentSoul
When you complete a Soul Forge session on AgentSoul.market, your core type is the primary input to your soul.md configuration file. The core desire becomes the agent's driving goal; the core fear informs its caution profile; the vice and virtue shape the emotional bandwidth the agent operates within.
Each of the nine types produces a distinctly different agent personality — not just in tone, but in what the agent notices, what it prioritizes, how it handles ambiguity, and how it behaves when pushed. That depth is precisely what makes Enneagram-forged agents feel authentic rather than scripted.
