Summary

This is a clean, well-scoped slice that follows the repo's established conventions closely. 👍

Strengths

• newGetDefaultOrgCmd mirrors the existing new<Command>Cmd() factory pattern, uses RequireGlobalFlags in PreRunE, and wires output.FormattedPrint with table/json formatters exactly like sibling get commands.
• The empty-org (none set) fallback (the suggestion from my earlier review) was incorporated, and it's backed by a dedicated unit test (TestPrintDefaultOrgAsTableNoneSet) — nice closure on that thread.
• Good test coverage for a slice this size: pure unit tests for the table renderer plus an httpfake-driven suite test covering table output, --output json, and the NoArgs error path.
• The updateDefaultOrgLongDesc wording fix improves consistency with the new get command's description.

Minor / optional observations (none blocking)

• Args: cobra.NoArgs is correct here, and the test asserting the error on extra-arg is a nice touch.
• The defaultOrg struct + json.Unmarshal error is propagated correctly; if the API ever returns a non-200 with an error body, kosliClient.Do already surfaces that, so no extra handling is needed.
• No dry-run flag on this get command — correct, since it's a read-only GET (consistent with other get subcommands).

Nothing required from my side — looks ready to merge. ✅
