Review comment on the verify step: dumping every open PR under --limit 1000 wastes agent context and re-truncates past 1000. Ask the exact question server-side instead: gh pr list --state open --base <branch> --json number --jq length, whose output is a single count that is exact at any number of open PRs. Skill, checklist, and the cookbook dependent-check line all use the per-branch form.
