## Why ae_create_composition is rated Medium

This tool creates a new composition (a reversible data structure in After Effects) with specified parameters. It modifies the project by adding new content but does not execute arbitrary code, delete data, or move money. The reversible nature of creation (can be undone/deleted) places it in Write rather than Execute or Destructive.

From the tool's own definition: "Tool description states 'Create a new composition' which is a create action that modifies project state by adding a new artifact."

## Use case

AI agents use ae_create_composition to create or update resources in Ae, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ae environment.
