$ARGUMENTS
vastai show instances # Table view
vastai show instances --raw # JSON
vastai show instance <ID> --raw # Single instance JSON
vastai start instance <ID>
vastai stop instance <ID>
vastai reboot instance <ID> # Restart, keeps GPU priority
vastai recycle instance <ID> # Destroy + recreate fresh
vastai destroy instance <ID> # PERMANENT — confirm first
Batch: start instances, stop instances, destroy instances take multiple IDs.
Always confirm destroy with the user — it is irreversible.

When showing instances, note:
Manage Vast.ai autoscaling endpoints and worker groups for production deployments. Use when setting up auto-scaling GPU inference, managing worker pools, or deploying services.
Launch a GPU instance on Vast.ai. Use when the user wants to create, start, or spin up a new GPU machine for training, inference, or development.
Manage Vast.ai persistent storage volumes — search, create, delete, clone, and attach volumes to instances. Use for persistent data across instance lifecycles.
Run a job on a Vast.ai GPU instance end-to-end: find a GPU, launch it, execute the job, monitor it, and destroy the instance when done. Use when the user wants to run a training job, inference task, script, or any workload on a remote GPU.
Search for available GPU machines on Vast.ai. Use when looking for GPUs to rent, comparing GPU pricing, or finding machines that match specific requirements.
Set up Vast.ai CLI — configure API key, verify installation, set up SSH keys, and check account. Use when the user needs to get started with Vast.ai or is having authentication issues.
