Claude Code /loop: Automate PR Babysitting and CI Fixes

Every developer knows the pain: you’re deep in flow state, working on a feature, when suddenly CI fails on your PR. Or a reviewer leaves comments that need addressing. The context switch breaks your momentum.

Claude Code’s /loop command solves this by automating PR monitoring and fixing. Your AI pair programmer watches your PRs in the background and handles issues while you stay focused.

What is PR Babysitting?

PR babysitting means having Claude automatically:

  1. Monitor your pull requests for CI failures
  2. Detect and fix build errors
  3. Handle incoming review comments
  4. Push fixes without your intervention

One Reddit user put it perfectly: “CI failures and review comments are death by a thousand context switches — having that handled in the background is a legit workflow shift.”

Setting Up Your First Loop

The basic syntax is straightforward:

Terminal window
/loop 10m babysit PR #42

This tells Claude to check PR #42 every 10 minutes and report any changes.

Interval Recommendations

  • 5-10 minutes: For active PRs with ongoing CI
  • 15-30 minutes: For monitoring stable PRs
  • 1 hour: For low-priority background watching

The scheduler rounds to clean intervals, so specify what you need and Claude will confirm what it picked.

Comprehensive PR Monitoring

Here’s a prompt that covers the full babysitting workflow:

Terminal window
/loop 10m babysit my open PRs:
For each PR I'm assigned to:
1. Check if CI has run since last check
2. If CI failed:
   - Read the error logs
   - Identify the root cause
   - Create a minimal fix
   - Push and comment what was fixed
3. Check for new review comments
4. If comments need response:
   - Address in a worktree
   - Push and reply
5. Update .pr-state.json with current status

This creates a comprehensive monitor that handles CI failures, review comments, and maintains state between iterations.

Handling Different CI Failure Types

TypeScript Errors

Terminal window
/loop 10m check PR #42:
If TypeScript compilation fails:
1. Read the error output
2. Fix type mismatches
3. Add missing type annotations
4. Push fix

Test Failures

Terminal window
/loop 15m check PR #123:
If tests fail:
1. Identify failing test names
2. Check if it's a flaky test (compare with main)
3. If code issue: fix the implementation
4. If test issue: update test expectations
5. Push and report

Lint Warnings

Terminal window
/loop 20m check PR #456:
If lint errors exist:
1. Run eslint --fix for auto-fixable issues
2. Manually fix remaining issues
3. Push changes

Using Worktrees for Safe Fixes

When fixing PR issues, Claude can use git worktrees to avoid conflicts with your current work:

Terminal window
/loop 15m monitor PR #789:
If CI fails or comments arrive:
1. Create worktree: git worktree add .worktree/pr-789
2. Switch to PR branch
3. Make fixes
4. Push from worktree
5. Clean up worktree

This keeps your main workspace untouched while Claude handles fixes in isolation.

Understanding the Limitations

3-Day Expiry

All recurring tasks expire after 3 days. This prevents forgotten loops from running indefinitely. If you need longer monitoring, recreate the loop before expiry.

Session-Scoped

Loops only run while Claude Code is active. Closing your terminal stops all scheduled tasks. For persistent monitoring, consider:

  • Desktop scheduled tasks: Run without an active terminal
  • GitHub Actions: Cloud-based automation that survives restarts

Context Management

For long-running loops, manage context drift:

Terminal window
/loop 10m babysit PR #42:
1. Read .pr-state.json for previous actions
2. Check current PR status
3. Handle any new issues
4. Update .pr-state.json with timestamp and actions
5. Keep output concise

Real-World Example

A Reddit user shared their pre-/loop solution:

“I asked Claude to babysit my PR and fix comments and CI failures. It created a bash script that sleeps and polls GitHub which runs after it submits a PR. I’ve been using it two weeks and it works great.”

Now /loop provides this capability natively without custom scripting.

When to Use /loop vs Alternatives

Use CaseTool
Active PR monitoring during development/loop
Long-term CI automationGitHub Actions
Simple scheduled scriptscron jobs
PR monitoring without terminalDesktop scheduled tasks

Getting Started

  1. Open Claude Code in your project
  2. Create a PR to monitor
  3. Start a loop:
    Terminal window
    /loop 10m babysit PR #123
  4. Continue working while Claude watches

Check active loops anytime:

Terminal window
what scheduled tasks do I have?

Cancel when done:

Terminal window
cancel the PR babysitting job

The Bottom Line

PR babysitting with /loop transforms Claude from a tool you invoke into a teammate that’s always running. The mental shift is significant—you stop worrying about CI failures interrupting your flow because someone else is handling them.

For teams drowning in context switches, this feature alone can meaningfully improve developer productivity.
