Prompt for your agent

Goal: Give my agent computer use with an open-source tool.
Setup: agents used in source: Command Code; tools/MCPs stated: UI-TARS.
Steps:
1. Ask the agent to use an open-source computer-use model (UI-TARS).
2. Have it create an MCP server for it.
3. Test it on a simple task.
Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify.
