One. Executive Summary

Logline Agent System is a multi-agent AI pipeline for LoglineOS - the AI pre-production platform for film and video. It takes a raw screenplay and produces a complete Master Sheet with sixty-one fields per shot, including director decisions, camera work, lighting, character performance, VFX, and image generation prompts with variation templates.

The system replaces a single Claude API call (fourteen columns, no continuity, no quality gate) with a nine-agent pipeline where two agents use the ReAct pattern (tool-calling reasoning loop) and seven use single-call workflow. The result: scene-by-scene continuity, every decision motivated by the story, and a quality gate that actively investigates shots for contradictions.
