[Feature request] Can Ruff "output format" group by violation code?

[jsh9]

Currently the Ruff linter offer "grouped" as one of the output formats, which groups violations by file.

Can there be another option to group by violation code?

The benefit of this option is: nowadays we often use AI coding assistants (such as Claude Code, Codex, ...) to fix linter issues for us. I've found that AI performs better when fixing one type of issues at a time.

That's interesting. I think I would probably tell the agent to --select one rule at a time in that case, but we could still consider it.
