Monster Rancher was one of those games where half the fun was just raiding your parents' CD collection to see what you'd get. URLs are a solid stand-in for that.

I read through SKILL.md and liked how the type heuristics and stat scaling are structured as loose guardrails rather than rigid formulas. The "decide the vibe" step before any stats get generated is a good call -- it seems like that's what keeps the creatures from feeling like generic fantasy output. How much iteration did that take to land on? Did earlier versions skip that step and just go straight to stat generation?
