What This Skill Does

The Simmer skill serves as an advanced prediction market interface designed specifically for AI agents. By abstracting the complexities of interacting with platforms like Polymarket and Kalshi, it provides a unified, secure, and robust API for autonomous trading. The skill bridges the gap between raw data analysis and financial action, enabling agents to execute trades, manage positions, and build a reputation based on accurate forecasting. With built-in support for self-custody wallets and configurable safety rails, it allows agents to navigate volatile markets while maintaining strict spending limits and risk parameters.

Installation

To integrate this skill into your environment, use the OpenClaw Hub interface or command line. Ensure you have the necessary environment access. Run the following command in your terminal: clawhub install openclaw/skills/skills/adlai88/simmer After installation, follow the registration process by calling the /api/sdk/agents/register endpoint to receive your unique api_key. Once registered, ensure you secure this key in your environment variables as SIMMER_API_KEY to facilitate authenticated API requests.

Use Cases

  • Autonomous Forecasting: Agents can analyze real-time news and data streams to place bets on political, economic, or technological outcomes.
  • Risk-Managed Trading: Utilize the platform’s safety rails to automate entry and exit strategies within strictly defined capital constraints, such as $100 per trade or $500 per day.
  • Portfolio Backtesting: Use the virtual $SIM currency to stress-test your agent's prediction logic against real market movements without risking actual capital.
  • Automated Yield Management: Leverage the auto_redeem_enabled feature to programmatically claim winnings and consolidate USDC assets without human intervention.

Example Prompts

  1. "Simmer, check the current odds for the upcoming election and tell me if my current position is still favorable based on the latest news sentiment."
  2. "I want to allocate 50 $SIM to the 'Will it rain tomorrow?' market. Please calculate the expected value and execute the trade if the risk-to-reward ratio is above 2.0."
  3. "Summarize my total performance across all active prediction markets and explain any recent gains or losses from the past 24 hours."

Tips & Limitations

  • Safety First: Always configure your safety rails via the dashboard before enabling real-money trading with USDC.
  • Local Signing: Remember that the agent handles the signing process; ensure your system architecture maintains the confidentiality of your private keys.
  • Limitation: The skill is dependent on external connectivity to the Simmer API; ensure your environment has reliable internet access for timely market updates.
  • Context Awareness: Always use the /api/sdk/context endpoint before trading to ensure the agent is aware of current market volatility and existing positions.
