A complete rush assessment requires building levels and village context that the public player API does not provide. A responsible public analysis therefore focuses on visible offense: heroes, troops, spells, pets and Hero Equipment.
Look for imbalance
Compare unlocked offensive items with their API-reported maximum levels. A large gap in several core heroes or in the army a player actually uses is a useful warning signal, but not proof that the whole village is rushed.
Avoid a misleading percentage
Do not combine unknown building levels with known offensive levels and call the result total completion. Clash Astuce labels its score as visible offense and explains the rule version behind it.
