How it works

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.

Install

Download the SKILL.md into your agent skills folder, or clone it from GitHub. Then connect Unsora so generation can run.

Install

curl -O https://github.com/sadekxD/ugc-ad-generator-skill/raw/main/SKILL.md

Or drop the file

Place SKILL.md at skills/create-thumbnail/SKILL.md in your agent project, then restart or reload skills.

Try saying

01
“Make 4 YouTube thumbnails for a video about AI UGC ads — shocked expression.”
02
“Thumbnail with my face reference, bold text energy, 16:9.”
03
“Generate CTR covers mimicking this template layout.”
