How It Works

Claude Code 2.1.89 introduced `/buddy` — a virtual companion that lives in your terminal. The companion's traits (species, rarity, stats, etc.) are **deterministically derived from your account identity**, not random per hatch.

The algorithm chain:

account ID + "friend-2026-401"  →  Bun.hash (wyhash)  →  32-bit seed
                                                              ↓
