Marvel Rivals Assistant

Overview

An LLM-backed assistant that suggests team compositions for Marvel Rivals based on synergy scoring across the hero pool. You give it your two locked-in picks; it surfaces the best third pick.

How it works

• Hero pool encoded with role tags (Vanguard / Duelist / Strategist) and synergy edges
• Current team state fed to an LLM with a system prompt that asks for a counter-pick that balances composition
• Output: a ranked list of suggested heroes with a one-line rationale for each

Why it's here

It's a small thing, but it's the kind of thing I'll build for myself anyway — and the synergy-graph + LLM-reasoning hybrid pattern generalizes to any "what fits with what" problem (recommender systems, ingredient pairings, scheduling).

• LLM API for the reasoning step
