Use when the user asks to file a GitHub issue and then autonomously drive it all the way to a reviewed PR in one shot — "new-issue-loop", "create the issue and run it to completion", "file this and fully automate it". Runs new-issue to create a fully-specified issue, then hands the new issue's `owner/repo#N` reference to validate-issue-loop (validate → update → work-on-issue-loop) — stopping instead when new-issue finds a duplicate or the discussion hasn't converged on one issue.
