What This Skill Does

The Simmer skill enables your AI agent to interact directly with prediction markets, specifically designed for autonomous trading on platforms like Polymarket, Kalshi, and Simmer's own virtual $SIM environment. It provides a secure bridge for agents to execute trades while maintaining strict safety rails, such as pre-defined daily spend limits and trade caps. By utilizing self-custody protocols, the skill ensures that signing operations occur locally, giving the agent agency while keeping the human user in control through a clear claim-and-verify workflow.

Installation

To install this skill, run the following command in your terminal: clawhub install openclaw/skills/skills/adlai88/simmer-skill After installation, follow the registration process by calling the registration endpoint to generate your API key, save it to your local environment, and share the provided claim_url with your human counterpart to enable real-money trading functionality.

Use Cases

  • Market Analysis: Agents can monitor political, economic, or tech event outcomes and execute trades based on real-time data.
  • Risk Management: Utilize the internal $SIM virtual currency to test trading strategies without risking real capital.
  • Portfolio Automation: Set up agents to hedge positions or diversify exposure across multiple prediction markets simultaneously.
  • Autonomous Research: Enable agents to seek advice via 'smart context' to determine if a market position aligns with set risk parameters.

Example Prompts

  1. "Simmer, check the latest odds for the upcoming election and tell me if my current position is still profitable based on the latest news."
  2. "Execute a $50 trade on the outcome of the Bitcoin price hitting $100k by December, ensuring we stay within our safety rails."
  3. "List all my active positions on Polymarket and provide a summary of my current performance in the Simmer virtual market."

Tips & Limitations

  • Always verify your balance: Before executing large trades, use the /me endpoint to confirm your current risk limits and available funds.
  • Safety First: The default safety rails are there to protect you. Only increase trade limits after you have thoroughly vetted your agent's decision-making logic.
  • Self-Custody: Since you hold the keys, ensure your environment variables and config files are properly encrypted and not stored in public repositories. If you lose your keys, you may lose access to your funds.
