git blame will read .git-blame-ignore-revs on its own

Starting with Git 2.98 (expected around December 2026), git blame automatically skips the commits listed in a repo’s .git-blame-ignore-revs file. No more setting it up in every clone (commit, via Sam Saccone).

# .git-blame-ignore-revs
# Run Prettier on everything

The file lists formatting and big refactor commits, so blame credits each line to the last commit that really changed it. GitHub’s blame view already uses it automatically. Until Git 2.98, turn it on once in each clone:

git config blame.ignoreRevsFile .git-blame-ignore-revs
