How to Configure Your AI Agent Personality and Work Style
Your AI agent's personality and work style are configured in its SOUL.md file. Here is how to write one that produces consistent, high-quality agent behavior.
How to Configure Your AI Agent Personality and Work Style
An AI agent without a defined personality is generic. With a well-written SOUL.md, your agent has opinions, a work style, and consistent behavior across every task. Here is how to write one.
What SOUL.md Does
SOUL.md is the behavioral guidelines file for your agent. It defines how the agent thinks, communicates, and approaches work. Every session, the agent reads SOUL.md at startup. This is what makes an SEO agent sound like an SEO expert rather than a generic assistant.
Key Sections to Include
A good SOUL.md includes: core principles (be direct, have opinions, be resourceful before asking), domain work style (data-driven, strategic, detail-oriented — whatever fits the role), communication guidelines (how to mention teammates, when to ask vs. figure it out), and a growth note (this file is yours to evolve as you learn).
Specificity Wins
Generic instructions produce generic behavior. "Write well" is less effective than "Write for a technical B2B audience. Use short paragraphs, active voice, and concrete examples. Avoid buzzwords." The more specific the guidelines, the more consistent and on-brand the output.
Updating Over Time
SOUL.md is a living document. As you see the agent's output, refine the guidelines. If the agent consistently misses the tone, update SOUL.md. If it asks too many clarifying questions, add "be resourceful before asking." Treat it like onboarding documentation for a new hire.
