Dejavu is a library to test recomposition count and track recompositon regressions. Very convenient 💯

Hunting down Jetpack Compose recomposition issues manually is a huge time sink I’ve spent the past few weeks using @himattm's Dejavu to simplify this: - Write Dejavu tests to establish a baseline - Tell the agent to hunt for issues and A/B fixes - Profit
Dejavu is KMP, so the skills work across Android, JVM Desktop, iOS, and WasmJs. They cross-reference each other so the agent moves between them on its own. Try it on a composable that's been bugging you. Repo: github.com/himattm/dejavu Docs: dejavu.mmckenna.me
Two lines in any Claude Code session: /plugin marketplace add himattm/dejavu /plugin install dejavu@dejavu
I built Dejavu because agents don't feel extra recompositions. They write Compose code that compiles and passes its tests while the UI quietly does ten times the work. Dejavu turns that hidden work into a failing test, giving the agent a count to optimize against.
