When to use it
Use it when a team wants one way of doing code review, or to show a new member what happens after they open a pull request. Automated checks come before people, and comments loop between updating and re-reading until approval.
Make it yours
- Keep the second reviewer decision for core modules; small teams can delete it.
- Put the expected turnaround in a node, such as "First response within one business day".
- If you require a merge method, say so in the last step, such as squash merge.

Draw a code review flowchart with Mermaid flowchart TD syntax. The developer finishes and self-tests, opens a pull request, and automated checks run; if they fail, fix the issues and resubmit. If they pass, assign a reviewer who reads the change. If changes are requested, the developer updates and replies and the reviewer reads again. If not, approve. If a second reviewer is required, assign again; otherwise merge to main, delete the branch and link the issue. Use diamonds for decisions and no parentheses in node text. Output only the mermaid code block.
FAQ
- How do I show blocking versus optional comments?
Split the decision into two exits, "Must fix" and "Suggestion", and send suggestions straight to approval.
- Can it go into our engineering handbook?
Yes. SVG is the sharpest in documents, or use a share link so everyone opens the current version.
- Can I show how long reviews take?
Add the target to the reviewer node with a line break. Actual durations belong in your metrics dashboard, not on the chart.
