Jetpack Compose animation APIs: animate*AsState, updateTransition, AnimatedVisibility, AnimatedContent, Animatable, AnimationSpec, and graphicsLayer lambda for phase-optimal animations. Trigger: when implementing animations in Compose, using AnimatedVisibility, AnimatedContent, graphicsLayer transforms, or choosing between animation APIs.
Jetpack Compose architecture patterns: Clean Architecture layering, MVVM/MVI with UiState/UiAction, Screen/Content split, collectAsStateWithLifecycle, stable UI models, and ViewModel scoping rules. Trigger: when structuring a Compose screen, wiring a ViewModel to UI, choosing MVVM vs MVI, handling UiState/UiAction patterns, or reviewing Compose architecture anti-patterns.
Context-aware audit of Jetpack Compose and Compose Multiplatform codebases. Discovers project shape, classifies findings by severity (critical/warning/suggestion), and routes each finding to the canonical performance skill for the fix. Trigger: "audit my Compose project", "review CMP code", "find perf issues in Compose", "compose code review", "recomposition audit", "CMP audit".
Jetpack Compose composition internals: state management, recomposition mechanics, stability, component identity, CompositionLocal, and the 3-phase performance model. Trigger: when working with Compose state, recomposition bugs, derivedStateOf, remember variants, stability annotations, LazyList performance, or CompositionLocal.
Jetpack Compose side effects: LaunchedEffect, DisposableEffect, SideEffect, produceState, snapshotFlow, rememberUpdatedState, and derivedStateOf — with keys, cleanup contracts, and performance rules. Trigger: when working with LaunchedEffect, DisposableEffect, SideEffect, produceState, snapshotFlow, or any coroutine-based effect in Compose.
Performance-first AI agent skills for Jetpack Compose and Compose Multiplatform. Each skill leads with the 3-phase model (Composition → Layout → Drawing) and includes decision trees, critical patterns, and a shared performance toolchain.
Use compose-audit to scan an existing codebase for bad practices, classify findings (critical / warning / suggestion), and route each issue to the right fix skill.

CMP column: ✅ fully commonMain-safe · ⚠️ partial (version-gated or some Android-only items) · ❌ Android-only.
Full registry: AGENTS.md
Every skill in this repo carries a ## CMP Applicability table documenting which APIs are commonMain-safe, which are Android-only, and which require version gates.
Canonical CMP rules: skills/_shared/cmp-platform.md — source-set map, forbidden imports, expect/actual patterns, lifecycle version gates (2.8 / 2.10), navigation options (CMP Nav3 alpha), iOS accessibility, tooling matrix, and version pinning.

Add AGENTS.md to your Android repo (or symlink it) so agents load the skill index and the Composition → Layout → Drawing rule before writing Compose code.
Each skill is self-contained: SKILL.md + references/ (no external doc dependencies). compose-audit also ships assets/ (report template and routing table).
