What is a SOUL.md?

A SOUL.md is a markdown file that defines your AI agent's personality, values, communication style, and behavioral boundaries. It's the identity layer that turns a generic LLM into your agent.

The SoulSpec standard defines a minimal file structure โ€” SOUL.md + STYLE.md + soul.json โ€” that gives agents a persistent, portable identity. No build step. No runtime dependency. Just markdown and JSON.

It works with any framework that reads SOUL.md โ€” including Cursor, Windsurf, Continue, and custom agent pipelines.

Why it matters

๐ŸŽฏ

Consistent behavior

Your agent responds the same way every time โ€” across sessions, tools, and contexts.

โšก

Faster iteration

Change tone, values, or boundaries in one file instead of rewriting system prompts across your stack.

๐Ÿ”„

Portable identity

Move your agent between frameworks without losing its personality. One spec, any platform.

๐Ÿค

Team alignment

Everyone on the team knows how the agent should behave. The SOUL.md is the source of truth.
