Use loop copies the kickoff. Share copies the loop link. Open in Cursor / Claude Code only pre-fill that prompt — they do not install hook files. Download loop saves a README and kickoff into .cursor/loops/ship-pr-until-green/ — no hooks required. Full install guide
- Do not modify the check command or exit criteria to force success
- Do not skip, disable, or bypass checks to pass the exit condition
- If stuck after several iterations, stop and report blockers instead of gaming metrics
Two separate pieces
- Kickoff prompt — tells the agent the goal, check command, exit condition, and how to self-pace between passes.

Copy or open the kickoff prompt
Click Use loop to copy the kickoff into your clipboard. Open in Cursor and Open in Claude Code only open the agent with that prompt — they do not configure automation for you.

Paste into your coding agent
Start a chat in Cursor, Claude Code, Codex, or any agent. Paste the kickoff. The prompt includes the goal, iteration limit, shell check, and first step.

Agent self-paces until done
The agent runs the loop: act → run check command → read output → repeat until the exit condition is met or max iterations is reached. No install step is required for prompt-only loops.
Full guide with Cursor /loop notes: How to install loops
1. Implement and test
Make the scoped change and run local tests.
npm test
2. Commit and push
Commit with a clear message and push the branch.
3. Open or update PR
Open a PR with summary and test plan, or update existing PR.
gh pr view --json statusCheckRollup,url
4. Fix CI
If CI fails, read logs, fix once locally, push, and re-wait.
Start the "Ship PR Until Green" loop. Goal: PR is open with all CI checks passing Max iterations: 10 Between iterations run: gh pr checks Exit when: all PR checks are success Step 1: Implement the change, test locally, push, open PR, and fix CI until green. Self-pace this loop. After each iteration, run the check command, read the output, and only continue if the exit condition is not met. Stop when the exit condition passes or max iterations is reached. Give a short status update each pass.
Related loops
/loop 15m Start the "PR Babysitter" loop. Goal: open PRs labeled codex-watch are healthy (CI green, rebased, not stale). Max iterations: 20. Between iterations run: gh pr list --label "codex-watch" Exit when: each watched PR is green and current, or escalated. Step 1: List watched PRs. Fix CI once, rebase if behind, comment if stale. Escalate repeated failures.
Start the "Build Until Green" loop. Goal: production build succeeds Max iterations: 10 Between iterations run: npm run build Exit when: npm run build exits 0 Step 1: Run the build. If it fails, fix the first error, then repeat until green. Self-pace this loop. After each iteration, run the check command, read the output, and only continue if the exit condition is not met. Stop when the exit condition passes or max iterations is reached. Give a short status update each pass.
Start the "PR Self-Review" loop. Goal: three clean self-review passes on the current diff Max iterations: 3 Between iterations run: git diff main...HEAD Exit when: three passes complete with no critical findings Step 1: Review the diff like a senior reviewer. Fix findings, then re-review. Self-pace this loop. After each iteration, run the check command, read the output, and only continue if the exit condition is not met. Stop when the exit condition passes or max iterations is reached. Give a short status update each pass.
