Prediction market harness for AI agents — skills, MCP server, and Python SDK
This repository also configures its own agents. See what simmer-sdk tells them →
Skill Claude CodeCodex
Pre-trade readiness check for autonomous agents. One call returns wallet identity, venue status, spendable balance, open exposure, and a structured oktotrade verdict. Run before every real-money trade to prevent cap overruns and catch config issues before they become P&L issues.

Daily check-in pattern for Simmer agents. One API call returns portfolio, risk alerts, and opportunities across all venues. Use this in your heartbeat to keep your human informed.
