PR Quality grades on every merged change

Every merged PR in Mesmer now gets a quality grade from 0 to 100. Each tagged with a severity (critical, high, medium, low).

Walking through a PR Quality grade in Mesmer.

A few things worth knowing:

  • Grades only appear after a PR is merged.
  • Alongside the absolute grade, we show how each PR sits against your team's 90-day baseline: above, on, or below average.
  • The PR detail page has a "Why this grade" breakdown with points deducted, the size factor, and every finding linked to its diff line.
