Triage many open GitHub PRs at once — for each PR, check its CI verdict and mergeability, then merge (with admin bypass + squash fallback) or close, in bulk. Use when the user wants to clean up a queue of stale PRs ("close all the old Snyk PRs", "merge anything green and close anything red", "process all the dependabot PRs across my repos") spanning more than a handful of PRs. Trigger on phrases like "go through all my open PRs", "merge or close them all", "clean up the PR backlog", "any PR that's failing CI / unmergeable / stale", or when the user wants the same per-PR decision rule applied to a list of PRs. Sibling skill to `gh-bulk-repo-edit`, but the surface is PR state changes (merge / close / leave), not file contents.
