Start a durable Highway agent that pursues goal to completion.

Returns immediately with a workflow_run_id. The agent runs server-side and survives this client disconnecting. Use get_status to follow it and to see any actions awaiting your approval.

Get an agent run's status, progress, result, and any pending approvals.

pending_approvals lists actions the agent has paused on; pass an approval_key to the approve tool to let it continue.

Approve (or reject) a pending agent action to resume the durable run.

Set approved=False to reject. This works across sessions and devices: you can approve from one client an action a run started from another.

Schedule an agent to run goal repeatedly on a cron schedule (UNATTENDED).

cron_expression is standard 5-field cron in UTC, e.g. '0 9 * * ' = daily 09:00, '/30 * * * *' = every 30 minutes. The scheduled agent runs WITHOUT per-run human approval (creating the schedule is the authorization), so only schedule goals you trust. Uses Highway's durable cron (survives restarts; no history bloat). Returns the schedule details.
