Wiring the Agent into CI: Pre-merge Gates
Integrate agent PRs into CI — status checks, required reviews, auto-merge rules.
What You Will Learn
- Configure CI gates for agent PRs.
- Set required reviews.
- Configure auto-merge rules.
- Prevent unauthorized merges.
- Audit CI behavior.
Why This Matters
Agent PRs without CI gates can merge untested code. Proper gates ensure quality and safety.
Concept Explained
CI gates for agent PRs: required status checks (tests, lint, security scan), required reviewers (human review), auto-merge rules (only on green + review).
How It Works
Configure branch protection: required checks, required reviewers, dismiss stale reviews, require linear history. Auto-merge only when all green + review approved.
Step-by-Step Tutorial
1. Required status checks
Tests, lint, type-check, security scan. All must pass.2. Required reviewers
At least 1 human review for agent PRs. (Configure CODEOWNERS.)3. Dismiss stale reviews
If new commit pushed, dismiss previous approvals.4. Require linear history
Merge commits only (no squash). Cleaner history.5. Auto-merge rules
Optional: auto-merge when green + approved. Use carefully.Real-World Example
A team configured: required tests + lint + security scan, 1 human review, dismiss stale, no auto-merge. Agent PRs went through same gates as human PRs. Quality was high; no untested code merged.
Example Prompts / Commands / Code
# Via GitHub UI or API:
Branch protection rule for 'main':
- Require pull request before merging: YES
- Required approvals: 1
- Dismiss stale pull request approvals: YES
- Require status checks: YES
Required checks:
- tests (GitHub Action)
- lint (GitHub Action)
- type-check (GitHub Action)
- security-scan (GitHub Action)
- Require branches up to date: YES
- Require linear history: YES
- Do not allow bypassing: YES
# .github/CODEOWNERS
# Agent PRs to auth/ require security team review
/src/auth/ @security-team
# Agent PRs to infra/ require DevOps review
/infra/ @devops-team
# Default: any maintainer
* @maintainers
Common Mistakes
- No required checks — untested code merges.
- No required reviews — agent PRs merge without human eyes.
- Auto-merge on green only — skips review.
- Bypassing gates for 'urgent' PRs — sets bad precedent.
Best Practices
- Require tests, lint, type-check, security scan.
- Require at least 1 human review.
- Dismiss stale reviews on new commits.
- Use CODEOWNERS for path-specific reviewers.
- Don't bypass gates; configure auto-merge carefully.
Troubleshooting
| Problem | How to Fix |
|---|---|
| Agent PRs stuck waiting for review | Add CODEOWNERS with multiple reviewers. Or use auto-assign. |
| CI checks failing on agent PRs | Investigate. May be agent bug, or test gap. Refine issue. |
Practical Exercise
Your Turn
Configure branch protection for your repo: required checks, required reviews, dismiss stale. Test with an agent PR.
Professional Challenge
Set up CODEOWNERS for path-specific reviewers. Configure auto-merge for low-risk paths (docs) but not for code paths.
Key Takeaways
- CI gates for agent PRs: required checks, required reviews.
- Require tests, lint, type-check, security scan.
- At least 1 human review; use CODEOWNERS.
- Dismiss stale reviews on new commits.
- Configure auto-merge carefully.
