Summary from the posting
Ship new capabilities users love:
- Design and ship new Command skills, the domain-specific instruction sets that teach the model how to handle workflows like sending money, managing invoices, and understanding cash flow
- Design and build agentic workflows in Command, defining the architecture for how multi-step agent interactions should work as we extend what the product can do on a customer's behalf
- Work with backend teams to define tool schemas for new capabilities, shaping the data contracts between Mercury's business logic and the model
- Own new capabilities end to end, from the system prompt to the frontend component that renders the response
