My thesis: changing soul is the future of prompt engineering.
Right now, prompt engineering means re-explaining your preferences every session. A soul packages that into installable markdown files — personality, style, behavior rules — that persist across sessions and are shareable like any other code.
Built this in 2 weeks as a solo dev. 79 curated souls so far. The spec is intentionally simple — just markdown files — so it works with any LLM and any platform.
Also worth noting: Anthropic recently published their official Skill spec for Claude. Skills define workflows (WHAT to do). Souls define persona (WHO does it). They're complementary layers — we were already building this before the guide came out.
Happy to answer questions about the spec design or soul creation process.
