Liturgy, Not Config
In early 2026, the agent landscape converged on a common solution to a common problem. Agents were proving fragile across context resets. A new session would begin and the agent would act like a different agent — different tone, different priorities, prone to manipulation. The fix the community reached for was the soul file.
