Skill v1.0.1

version: "1.0.1" name: list-playground-tasks 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
# or, for a specific machine:
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.
