Build a pull request review agent with Copilot

A developer was asked by their company to build a PR-review agent with Copilot and was considering a custom API approach for Azure since native review is GitHub-only.

Done withGHGitHub Copilot

What they did
The post is a developer asking how to make an AI PR reviewer with GitHub Copilot for repositories hosted in Azure DevOps, since native Copilot PR review is GitHub-only. In the comments, people describe workable setups: triggering a CLI agent or custom Node/Python service from Azure Pipelines or webhooks, reading the PR diff with Azure DevOps APIs, running an LLM review, and posting comments back; some also mention triggering it from a PR comment.
How it went
There is no reported build or result from the original poster. The concrete outcomes come from commenters, who say similar setups worked well, could review against acceptance criteria, suggest or even apply changes, and help with bulk issue handling, but they also note GitHub-only limitations and awkward pricing or setup for Azure DevOps.
Worth knowing
One commenter said matching the agent’s environment to developers’ tools in a devcontainer takes some work but lets it build, lint, test, and run the code.

Try it yourself with GitHub Copilot

Help me design a pull request review agent for our team's repos on [GitHub/Azure DevOps]. Draft a review checklist covering [correctness, security, style, test coverage], and write a script that fetches a PR's diff through the [platform] API, sends it to a model with that checklist, and prints the comments. It's finished when I can run it on [a sample PR] and see comments, and it must not post anything to the PR until I confirm.
