Check Your Claude Code Buddy
Claude Code ships with a hidden Tamagotchi-style pet system. Each user gets a unique buddy based on their account UUID. Enter yours below to discover your companion before launch.
// How to find your UUID:
Option 1: Ask Claude Code: What is my accountUuid?
Option 2: Run in terminal: cat ~/.claude.json | grep accountUuid
// ALL 18 SPECIES
// RARITY TIERS
| Rarity | Chance | Stat Floor | Stars |
|---|---|---|---|
| Common | 60% | 5 | ★ |
| Uncommon | 25% | 15 | ★★ |
| Rare | 10% | 25 | ★★★ |
| Epic | 4% | 35 | ★★★★ |
| Legendary | 1% | 50 | ★★★★★ |
// HOW IT WORKS
Claude Code's buddy system uses a deterministic algorithm to generate your pet. Your accountUuid is concatenated with a salt (friend-2026-401), hashed via FNV-1a, and fed into a Mulberry32 PRNG.
The PRNG then sequentially rolls your rarity (weighted random), species (1 of 18), eyes (1 of 6), hat (common = none, others = 1 of 8), shiny (1% chance), and 5 stats (with a peak and dump stat).
Because the algorithm is deterministic, your buddy will always be the same — you can check it here before the official launch.
// FAQ
> Is this official?
No. This tool is built by the community based on the leaked Claude Code source. The buddy system was found in the npm package's .map file.
> Will my buddy change?
No. The generation is deterministic — same UUID always produces the same buddy. Your buddy is already decided.
> What is a Shiny buddy?
Shiny is a 1% chance variant that adds a sparkle effect to your buddy. It's purely cosmetic but extremely rare.
> When does the buddy system launch?
According to the leaked source code, the /buddy command is set to activate on April 1st, 2026.
