youtube-thumbnail
80 / 100 · Low risk
Fine to try.
Design, critique, and test YouTube video thumbnails and preview cards for stronger, better-qualified clicks. Use when developing thumbnail concepts, pairing a thumbnail with a title, directing image creation, checking small-screen legibility, preparing a YouTube experiment, or diagnosing thumbnail performance. Do not use for general video editing, channel strategy, or artwork for another platform.

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'youtube-thumbnail' ~/.claude/skills/'youtube-thumbnail' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
