The `hexel` CLI is for infrastructure and operations. Use it to manage compute, fleets, tasks, tools, policies, approvals, runtime, and auth. ## Authenticate ```bash theme={"dark"} export HEXEL_API_KEY="YOUR_API_KEY" hexel auth login ``` ## Compute ```bash theme={"dark"} # Sandboxes hexel compute sandbox create --tier standard hexel compute sandbox exec YOUR_SANDBOX_ID --code "print(1 + 1)" hexel compute sandbox list hexel compute sandbox release YOUR_SANDBOX_ID # Agents hexel compute agent register \ --name my-agent \ --image ghcr.io/your-org/agent:v1 \ --capabilities "chat,streaming" hexel compute agent list hexel compute agent delete YOUR_AGENT_ID # Instances (deploy is CLI-only, not in the SDK) hexel compute instance deploy YOUR_AGENT_ID --env-file .env hexel compute instance list hexel compute instance stop YOUR_INSTANCE_ID hexel compute instance redeploy YOUR_INSTANCE_ID hexel compute instance delete YOUR_INSTANCE_ID ``` ## Orchestration ```bash theme={"dark"} # Fleets hexel fleet list # Tasks hexel task list hexel task get YOUR_TASK_ID # Approvals hexel approval list hexel approval review YOUR_APPROVAL_ID --approve # Policies hexel policy list hexel policy evaluate ``` ## Tools ```bash theme={"dark"} hexel tools list hexel tools info YOUR_TOOL_SLUG ``` ## Runtime ```bash theme={"dark"} hexel runtime lease ... hexel runtime resources ... ``` ## Output formats Most commands support `-o table` (default), `-o json`, and `-o yaml`: ```bash theme={"dark"} hexel compute instance list -o json ``` ## Next steps Sandboxes, agents, and instances. Tasks, fleets, and approvals. Credentials and tokens.
