/iterate — Drive a PR to Merge-Ready

Iterate on a pull request until it passes all verification layers. You push, poll, fix, and push again — the loop only ends when the PR is green or a blocker requires human help.

No scripts — you are the orchestration loop. Uses only standard gh CLI commands that work on any GitHub repo.

Requires: gh CLI authenticated with repo access, a PR branch. Windows PowerShell equivalents for Bash-only assignment, redirection, and quoting patterns in this skill are in references/windows.md.

Discover what the repo has

Not every repo has all three verification layers. Before entering the loop, check which ones exist. Only poll layers that are actually set up.
