| description | Lists all examiner tasks (init and regular) for a playground. Use to check the status of challenge/tutorial tasks. |
| argument-hint | <playground-id> |
Default (preferred): list tasks via the API. This works for single- and
multi-machine playgrounds, shows tasks from all machines, and needs no SSH
tunnel - so it's the right tool for polling in a loop while waiting on init or
verification:
labctl playground tasks $0 -o yaml
Because this path is tunnel-free, prefer it over SSH for status polling - it
avoids exhausting the SSH tunnel slot pool (see the SSH tunnel discipline notes in
the run-playground-command skill).
Tasks are edge-activated (not level-triggered) and their status never regresses:
the examiner keeps evaluating a task until it first observes a success or failure
state, then it settles into its terminal state - completed (40) or failed
(35) - and never runs again, even if the world state later changes. The numerical
status only ever increases. So when polling, stop as soon as every non-helper task
has reached 40; a passed task cannot later flip back or fail.
The SSH-based alternative lists tasks for a single machine only (the one you SSH
into) and is rarely needed now:
labctl ssh $0 -- examinerctl task ls
labctl ssh $0 --machine <machine-name> -- examinerctl task ls
Use the get-playground-task skill with a specific task name to see detailed output
including stdout/stderr of the last execution.
