Provision the Linear twin from the CLI.

Install the Arga CLI, sign in once, then create a 60-minute twin run. The command waits until the environment is ready and prints its connection details.

Terminal

$ uv tool install arga-cli$ arga login$ arga twin-runs create --twins linear --ttl 60 --wait

Add --scenario-prompt to describe the state the twin should start with.

Build with the Linear twin

Connect the twin, seed realistic state, and run scenarios against a resettable service.

Make your agents more capablein the real world.

Spin up isolated environments with API twins, full traces, and production-data for apps and agents that need to act.
