no contexts found in config

Error message

no contexts found in config

What it means

Guard error in InteractiveDeleteOp.Run: ContextNames() returned an empty slice, so the kubeconfig has no contexts to present in the interactive fzf delete menu. The command aborts rather than opening an empty picker.

Solutions

  1. Create or import contexts into the kubeconfig before deleting
  2. Verify KUBECONFIG env var points to the intended file
Defensive patterns

Strategy: validation
