First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Generates short, bold text overlays — five words or fewer — for YouTube and social media video thumbnails that are readable at small sizes and convey the video's core hook at a glance.
Required: The video title or topic, and the central promise or finding of the video — what the viewer will get from watching. Optional: The visual already planned for the thumbnail (face, graphic, scene); the channel's established tone (dramatic, informative, conversational, authoritative); any words or phrases to avoid; whether you need text for the main overlay, a secondary label, or both.
Five numbered text options, each five words or fewer. Each option is on its own line with no punctuation beyond what is necessary for clarity. A one-line note follows each option explaining why it works and any visual pairing advice (e.g., "works best with a surprised face" or "pairs with a bold graphic, not a talking-head shot"). Labels indicate the approach: Number, Address, Claim, Intensifier, Question.
Video topic: A deep-dive video showing how cities have quietly changed zoning laws to allow more housing construction over the past three years, and why most people haven't noticed. The central finding is that housing supply in these cities has already started to increase, though rents haven't caught up yet. Channel tone: calm, analytical, grown-up. Thumbnail visual planned: an aerial shot of a dense residential street.
Number: 3 Years of Hidden Change Why it works: the number creates specificity; "hidden" creates curiosity without clickbait. Works with any visual.
Address: Your City Built More Why it works: direct address makes it feel personally relevant. Strong paired with an aerial shot where viewers might spot a familiar skyline.
Claim: Housing Supply Is Up Why it works: states the counterintuitive finding directly. Best for viewers already tracking housing policy — rewards the informed audience.
Intensifier: Quietly, Cities Changed Why it works: the adverb "quietly" carries the whole intrigue. Clean enough to sit over a dense visual without competing.
Question: Why Aren't Rents Falling? Why it works: names the tension the video resolves. Strongest as a secondary label beneath a main headline, or as a standalone A/B test against the Claim option.
