Compose recomposition performance
Router only — deep fixes live in compose-stability-diagnostics and compose-state-deferred-reads.
Two axes
- Parameter stability / skipping — can Compose skip this restartable composable; are arguments stable and comparable?
- Where
Stateis read — is frame-rateStateread during composition vs layout/draw?
Either axis can dominate; they combine independently.

| Primary suspicion | Next skill |
|---|---|
Skipping, unstable params, compiler/composables.txt churn |
compose-stability-diagnostics |
Frame-rate State read phase (composition vs layout/draw) |
compose-state-deferred-reads |
| Evidence for both | Apply both skills in parallel |
Review order
- Decide which axis fits the evidence; open the matching skill.
- If unclear, sample both — stability churn vs composition-phase reads of fast
State. - Re-measure after changes.
When NOT to apply
- Recomposition tracks real data changes, or the bug is correctness not cost.
- No profiler / compiler signal suggests a problem.
