/ How it works
Brief in. Clip out.
The skill teaches your assistant the UGC workflow end to end — from clarifying the brief to calling Unsora and iterating in chat.
01
Connect Unsora
Add the Unsora MCP to Claude, Cursor, or your agent. OAuth through the marketplace plugin, or an API key for local setups.
02
Install the skill
Add create-thumbnail so your assistant gathers topic, face refs, and variation count before calling the tool.
03
Brief the cover
Share the video hook, optional face URL, and how many options you want. The skill checks credits and runs create_thumbnail.
04
Pick a winner
Compare variations in chat, refine expression or layout, and keep the strongest CTR option.
