Nostr client for Android
Amethyst is an Android client for Nostr, a social network protocol that lets people control their own social activity and connections. People use it to read and publish Nostr content, follow accounts, and exchange encrypted direct messages from Android and other supported platforms. The catalogue add-ons support workflows for developing or operating the client.

Account state and in-memory event store patterns in Amethyst. Use when working with Account.kt (per-user state objects — kind3FollowList, nip65RelayList, muteList, bookmarkState, each exposing a .flow StateFlow), LocalCache (the object-level event store backed by LargeCache), User/Note model classes, or any ViewModel…

Patterns for extending amy, the Amethyst CLI in cli/. Use when adding an amy command, touching files under cli/src/main/kotlin/…/cli/, wiring a new subcommand into Main.kt, writing an interop test script that drives Amy, or extracting logic out of amethyst/ into commons/ so a CLI command can call it. Enforces the…

Android platform patterns for the amethyst/ module. Use when working with (1) Android navigation (Navigation Compose, type-safe routes, bottom nav), (2) runtime permissions (camera, notifications, biometrics), (3) platform APIs (Intent, Context, Activity, ContentResolver), (4) Material3 theming and edge-to-edge UI…

Signer abstraction patterns in Amethyst. Use when working with event signing, choosing between a local keypair (NostrSignerInternal), a remote NIP-46 bunker signer (NostrSignerRemote), or a NIP-55 Android external-app signer (NostrSignerExternal). Covers the abstract NostrSigner base class, SignerResult contract, how…

Use when investigating Jetpack Compose recomposition performance, skippable/restartable composables, composables.txt or compiler reports, Layout Inspector recomposition counts, or frame-rate State reads in composition vs layout/draw, and it is not yet clear whether the cause is parameter stability or deferred reads.…

Use when Jetpack Compose code reads scroll, animation, gesture, or other frame-rate State in composition, passes changing values across composable boundaries, or uses value-form layout/draw modifiers. Technique-layer skill — complements the codebase-specific compose-expert.
Skill Claude CodeCodex
Use when a Jetpack Compose screen-level composable takes a ViewModel/component/controller, collects state or effects, handles navigation/snackbars, or wires callbacks while also rendering layout. Technique-layer skill — complements the codebase-specific compose-expert and feed-patterns.

Use when auditing or migrating Log calls — flags interpolated Log.d/i/w/e that should use the lambda overload (allocation hygiene), catch-block Log.w/e that interpolate ${e.message} but drop the throwable (lost stack traces), and files still importing android.util.Log (no lambda overload, bypasses Log.minLevel).
