# Scenario Video Assembly

## Overview

Scenario has no editing tools on the MCP surface. Every compositor, concatenator, trimmer and
captioner is a deterministic model run through `model_run`. The compositor, concatenator and trimmer
ids are fixed and named below; Scenario ships two captioners, so that one is discovered with
`recommend`. Connection and the core loop: see the `scenario` skill; the clips themselves: see
`scenario-video`. If a sibling skill named here is missing from your available skills, load it with
`skill_get` (Scenario MCP) or ask the user to install it
(https://github.com/scenario-labs/skills#install); unattended, proceed from tool schemas and flag
the gap.
