Problem: Your AI agent is locked into your platform. Want to deploy it elsewhere? You rebuild from scratch.

Solution: Export your agent as a .soul file (ZIP archive with JSON). It contains personality, memory, bonds, and skills. Deploy on any platform. Switch frameworks. Keep your soul.

What's in it: - Portable: .soul files work on any platform that implements the protocol - Psychology-informed: Damasio somatic markers, ACT-R activation decay, LIDA significance gating, Klein self-model - Empirically validated: Soul 8.5 vs Mem0 6.0 in head-to-head benchmarks, 20/20 judge decisions favored Soul - Zero LLM dependency: Heuristic engine works offline - CLI integration: `soul inject claude-code` writes identity + memory into any agent's config in ~50ms (6 platforms) - Multi-soul MCP: Load and switch between multiple souls in a single session - Open standard: Like HTTP or MCP. Reference implementation in Python, TypeScript next

We published RFCs for community feedback. The spec is open for input.
