Thumbnail Maker Skill
Purpose
Produce a thumbnail that reflects the actual hook/claim of the finished
script — not a generic template image.
Process
- Pull the confirmed hook/core claim from the finished script.
- Generate or compose a thumbnail: bold short text (3-6 words max,
readable at small size) + a supporting visual tied to the actual topic. - Match the channel's established visual style (colors/fonts) if one
exists in the channel config; otherwise establish one on first run and
record it in the config for consistency across future videos. - Output at YouTube's recommended thumbnail spec (1280x720, under 2MB).
Rules
- Text on the thumbnail must be an accurate reflection of the video's
actual content — no clickbait that isn't backed by the script. - Keep a consistent style per channel over time so the channel is visually
recognizable.
