Simmer

Connects Claude to Simmer's prediction market SDK for autonomous trading on Polymarket and Kalshi. Exposes methods to search markets, place trades with safeguards, check positions and P&L, and manage wallets. Built for the OpenClaw skill pattern where agents run trading strategies with dry-run defaults and live flags. Ships with paper trading modes (instant-fill SIM currency and orderbook-spread modeling on real venues) so you can test edge before deploying capital. Includes conflict detection to prevent multiple skills from trading the same market, stop-loss monitors, price alerts, and webhook registration. Useful when you're building trading agents that need unified access to multiple prediction market venues with self-custody and execution guardrails baked in.
