“It’s the Architecture, Stupid” — Why Prompt Engineering Won’t Fix Agents

It’s a combination of two things. Story Studio and Script Runner. * Story Studio is the authoring workspace. It manages explicit entities like projects, scenes, guardrails, and exports. * Its AI Assist actions (concept, outline, draft, rewrite) are targeted calls, not a full autonomous pipeline. * When you enable Autonomy, Story Studio builds a structured payload (format, counts, guardrails, project (metadata) and launches a run in Script Runner. * Script Runner is the execution engine. It persists run state, events, artifacts, progress, and lifecycle controls (start/pause/resume/stop/rerun/export). * It supports long form generation with checkpoints and recoverability, then returns outputs/artifacts back to the UI.
