Show HN: Doxa – open-source platform for multiagent simulations using easy YAML

The idea behind the platform is to model complex economic-geopolitical scenarios with LLMs and simple YAML like this:

global_rules: epochs: 1 steps: 12 execution_mode: sequential maintenance: corn: 1 markets: - resource: gold currency: credits initial_price: 6.0 min_price: 1.0 max_price: 40.0 clearing: per_step - resource: corn currency: credits initial_price: 2.4 min_price: 0.5 max_price: 15.0 clearing: per_step actors: - id: player provider: google model_name: gemini-2.5-pro persona: Farmer-trader. Your core business is converting gold into corn. Keep enough corn to survive maintenance and monetize surplus. trading_mode: lob initial_portfolio: credits: 45 corn: 12 gold: 5 panic: 0.0

What about modelling geopolitical scenarios?
