- Reusable multi-agent debate primitive extracted from Flash Trader
- Cheap-models-first cascade with LLM escalation only on close calls
- Clean package with tests and examples
The debate pattern that powers Flash Trader, extracted into a reusable Python package: spin up a bull and a bear, let them argue a decision, and have a judge rule. It encodes the cost-aware cascade (rule-based first, LLM only when the call is close) that I reuse across six projects.
