If the list is empty, load gm-edit; otherwise load gm-eliminate. the gm-eliminate skill with row=<id>; session=<SESSION_ID>

Finish the work

Finishing the requested work is the goal of every run of this skill. A run that stops with work left undone is incomplete.
When an issue blocks a step (a failing check, a fault in a tool or service, a missing input, a network or environment fault), fix it in the same run: retry on a bounded or resumable route, use an alternate route to the same result, repair the fault where it originates, then continue the remaining work.
Stop only when the requested work is complete, or when a step is still blocked after every route has been tried. Then report the blocked step, the routes tried, and the evidence for each.
