Claude Code buddies were released as an easter egg on April 1, 2026. They were removed shortly after. <br><br>Buddies generated deterministically. Species, rarity, stats, and shiny status all derive from a hash of your account id, and re-roll every launch. BuddyDex brute-forces that pipeline to find the ids that produce the buddy you want.</p> <p>More information about the project is available <a href="https://iammatthias.com/posts/1775137360175-i-got-a-common-turtle">here</a>.</p> Experimentsclaude-codehashingbrute-forceeaster-eggdeterministic-generationreverse-engineering
