## What it does

The skill evaluates Roblox Murder Mystery 2 player data via Python scripts and CLI utilities. It scans knife skins, filters items by rarity, and highlights missing collection pieces. You can export performance charts and dashboards as CSV, JSON, PNG, or HTML files.

Generating tactical gameplay suggestions requires external AI models. For this reason, `.env` must define `API_OPENAI_KEY` or `API_CLAUDE_KEY`, or advice generation will fail. Custom profile parameters and scan filters live inside `config/profile.yaml`.
