Love this, been doing it manually. Curious if anyone's made a skill for enforcing modern patterns? Since training data skews toward older code, I often add "use 2025 best practices" etc. to get TW4 syntax, hooks, App Router, etc. Works great, would just love to automate it!
We just open sourced the code-simplifier agent we use on the Claude Code team.
Try it: claude plugin install code-simplifier
Or from within a session:
/plugin marketplace update claude-plugins-official
/plugin install code-simplifier
Ask Claude to use the code simplifier agent at the end of a long coding session, or to clean up complex PRs. Let us know what you think!
