Not Every Page Needs a Hero Metric
NEVER: Ship a decorative hero metric — a round, unsourced "10x faster" / "99.99%" / "500M+" with no denominator, no window, and no source, dressed in a gradient accent. A prominent number is allowed on exactly one condition: it shows actual user data (this account, this window, live, timestamped). Otherwise replace the stat row with one concrete product screenshot.
Show a prominent number only when it comes from real data, not as decorative gradient furniture

Why it matters
The skill permits a prominent metric under exactly one condition: it shows actual user data. The failure mode is the decorative, unsourced number — "10x faster", "99.99%", "500M+" — a round figure with no denominator, no window, and no source, used as visual furniture to make a hero feel substantiated. It belongs to the same family as identical repeated card grids: three cells that look like evidence and carry none.
So either the number is real (this account, this week, live, timestamped, with the series behind it), or it should not be there at all — replace the stat row with one concrete product screenshot, which at least shows the thing you are selling.
