DescriptionPersona is an open-source, themeable AI chat widget you can add to any website in minutes. SSE streaming, agent loops, tool use, and style isolation: zero framework dependencies.Pure Effect is a zero-dependency effect library for JavaScript and TypeScript.

You can read those objects in a test or replay them from a failed production run, and the database is never touched until the interpreter runs them.
