Readable at 100px width (mobile preview)\n2. Face takes 40-60% of frame\n3. Maximum 5 words of text\n4. High contrast between elements\n5. Consistent brand style\n\n### CTR Optimization\n1. Test multiple versions\n2. Study competitor thumbnails\n3. Match thumbnail to title\n4. Create curiosity gap\n5. Use proven color combinations\n\n### Common Mistakes to Avoid\n1. Too much text\n2. Low contrast colors\n3. Busy backgrounds\n4. Small faces\n5. Misleading imagery\n\n---\n\n\n## Reference Materials\n\nFor detailed code examples and implementation patterns, see [references/examples.md](references/examples.md).\n","tags":{"latest":"1.0.0"},"stats":{"comments":0,"downloads":358,"installsAllTime":0,"installsCurrent":0,"stars":0,"versions":1},"createdAt":1778154150280,"updatedAt":1778492872010},"latestVersion":{"version":"1.0.0","createdAt":1778154150280,"changelog":"Initial release — part of 188 AI agent skills collection by MTNT Solutions","license":"MIT-0"},"metadata":null,"owner":{"handle":"mtsatryan","userId":"s17bvyvkfhp17ybx0q3ak5dcsn85nqpv","displayName":"Michael Tsatryan","image":"https://avatars.githubusercontent.com/u/9057374?v=4"},"moderation":null}
