The GitHub Copilot PR stack
n8n catches the PR, Claude critiques the architecture, Copilot Workspace patches the branch. Not Cursor at the keyboard.
Who owns what
n8n
The event — pull_request opened, payload to Claude, status back. Not the diff write.
Try n8n (opens in a new tab)Claude
The critique — edges, regressions, what to test. Not the commit.
Try Claude (opens in a new tab)GitHub Copilot
The patch — Workspace edits on the branch, PR summary. Not webhook routing.

How to use this stack
- PR opens. n8n takes the diff. Do not open Cursor for this loop.
- Claude writes review notes and tests to add. One critic, not a second Copilot chat.
- Copilot Workspace applies the patch on the branch. CI stays GitHub Actions — not a stack slot.
- This is not the 2026 coding stack. That one is Cursor plus Claude Code plus CodeRabbit on your machine.
