OpenArt B-roll & Motion Graphics (MCP)

Everything here was proven in a shipped edit: three overlay clips, a reference-cloned talking head, and the billing/moderation scars to go with them.

Connection — this skill's one requirement

OpenArt has no API key. It runs over the OpenArt MCP connector (tools named openart_* appear in the session). Verify at the start:

• openart_account_get → email, plan, credit balance. If the tools are absent, have the user connect the OpenArt MCP in their client (claude.ai connectors / Claude Code MCP settings), then re-check.
