What is Simmer?
Simmer is the hosted agent workflow around a catalog of trading skills. Skills define how an agent selects markets and applies a strategy; users can also describe an idea and generate a new skill with configuration and a trading script. The platform starts with play money and separates real-market wallet linking from simulation.

- Keep the default dry-run or play-money mode.
- Set limits and inspect decisions.
- Link a wallet only for a separately chosen live workflow.
