Workflow
Cloudflare implemented a multi-role code review agent where a coordinator assesses pull request risk and assigns up to seven specialized reviewers (e.g., security, performance). The system deduplicates findings and requires a second verification pass before posting comments. Engineers retain final authority, with the ability to override the bot's recommendations.
Reported result
In one month, the system processed 131,246 review runs across 48,095 merge requests. The median review time was 3 minutes and 39 seconds, with a median cost of $0.98 per review. Engineers overrode the bot's decisions in only 0.6% of merge requests, indicating high trust in the automated findings.

Limitations
This workflow requires a robust internal tooling infrastructure to support parallel agent execution and risk classification. The reported metrics are specific to Cloudflare's scale and codebase; smaller teams may not achieve the same cost-efficiency or override rates. Integration with existing CI/CD pipelines and strict guardrails for read-only access are prerequisites.
Try it
Act as a DevOps engineer implementing a risk-based code review pilot. Input: A sample of 10 recent pull requests from [replaceable_repo_url] and a risk classification rubric. Step 1: Use an LLM to assess each PR's risk level (Low/Medium/High). Step 2: For High-risk PRs, simulate a multi-agent review by prompting separate 'Security' and 'Performance' reviewer personas. Step 3: Aggregate findings, remove duplicates, and generate a consolidated review comment. Step 4: Present the output to a senior engineer for validation before posting. Deliverable: A markdown report comparing the simulated review findings against the actual human review comments for the same PRs. Measure success by the percentage of simulated findings that match human-identified issues. Do not post comments to the live repository without explicit human approval.
