Yuanbao ASCII Pet

Problem

Many chat pet or check-in systems feel arbitrary: pet assignment lacks an auditable basis, and state changes are scattered across conversations, making growth hard to track. This skill turns the pet into a deterministic system for chat scenes: the same user_id with a fixed salt always produces the same pet, avoiding repeated rerolls, manual corrections, or state drift. It fits terminal-style play with rarity collection, light battles, and group rankings.

How it works

• Deterministic generation: user_id + salt xiaobai-xxp-2025 is hashed with FNV-1a and seeded into Mulberry32 PRNG for species, rarity, stats, and sparkle checks.
• ASCII presentation: each pet is rendered as terminal art with rarity, ✨ sparkle markers, and current status.
• RPG stats: smart, strength, luck, charm, and calm affect chat flavor, battle odds, random events, social interactions, and decay resistance.
• Growth loop: commands such as feed, train, battle, and photo update satiety, mood, and growth, while passive or social events can add small state changes.
• Persistence: data is written to skills/pet/pets.json, so a host agent or moderator can read, validate, and continue updating state.

Notes

This is not a full game server; it relies on the chat host to parse commands and apply state transitions. Rarity, sparkle, and exclusive mythic pets depend on the defined probability rules and scene context. Cross-platform sync, account migration, or richer leaderboards require additional service and permission integration.
