Usage:

  $ cloudcli sandbox ls
  $ cloudcli sandbox stop my-project
  $ cloudcli sandbox start my-project
  $ cloudcli sandbox rm my-project

Prerequisites:
  1. Install sbx CLI: https://docs.docker.com/ai/sandboxes/get-started/
  2. Authenticate and store your API key:
       sbx login
       sbx secret set -g anthropic   # for Claude
       sbx secret set -g openai      # for Codex
       sbx secret set -g google      # for Gemini

Advanced usage:
  For branch mode, multiple workspaces, memory limits, network policies,
  or passing prompts to the agent, use sbx directly with the template:

    sbx run --template docker.io/cloudcliai/sandbox:claude-code claude ~/my-project --branch my-feature
    sbx run --template docker.io/cloudcliai/sandbox:claude-code claude ~/project ~/libs:ro --memory 8g
