Use /goals with your agents to complete longer running, multi-step tasks in the background. Run it once or set it on a schedule.
The way it works: it sets a loop and doesn't complete until the goal is complete or it runs out of steps (set by you).
Try goals and let me know what you think!

Cosmic Agents can now execute tasks toward a Goal.
Describe the outcome in plain language and the Agent works toward it in a self-checking loop until the goal is met or it hits your step limit. Run once or on a schedule.

We're simplifying Cosmic AI down to three surfaces: Agents, Workflows, and Build with AI.
"Team Agents" are now just Agents, and standalone automations fold into Agents. The old Automations surface retires July 31, 2026.

They navigate real browser sessions, log in, fill forms, click through multi-step flows, and pull data back, the same way a person would.
