Every animation frame forces React Native to recompute layout on the JS thread. On a number that updates constantly, users feel a stutter.

A little agent I wrote that runs react-doctor on your PR and roasts you based on react code-quality regressions against main is one of the best things I have done for our react code quality.

This is a next gen React linter with autofix. Opus 4.6 + React Doctor must definitely have a PhD.

React Doctor is now an instant install for any React codebase I work on.

We've been using React Doctor in production for weeks and it's been fantastic. Giving agents guardrails to autocorrect code according to best practices is integral in an agentic-heavy codebase.

React Doctor just came out! A tool that detects anti-patterns in your React app: unnecessary useEffects, accessibility errors, and prop drilling you can avoid with Context.

I love trying out new toys Aiden makes. This week I took React Doctor for a spin on my Supercuts app and it scored a 77 — finding a really nice flow for cleaning up code with it.
