android-native-app

description

Build production-grade Android applications with strong opinionated defaults. Covers Jetpack Compose UI, native NDK pipelines via CMake FetchContent, design systems extracted from research, GitHub Actions release flows, and the local toolchain setup that makes iteration fast. Strongly research-led — spawns parallel research agents before any code is written. Triggers when the user asks to build a new Android app, scaffold one, port an existing app to Android, or substantially upgrade an existing Android project's engineering and design quality.

Android Native App

Build Android applications that feel like products, not prototypes. The goal isn't to make something that compiles — it's to make something that looks, feels, and operates at the level a discerning user would actually want to use. The path to that quality is short if you follow a research-first method and use the right defaults; it's a long slog if you don't.

suno-sfx-trimmer

description

Generate Suno Sounds prompts for game/app SFX and auto-trim the output to precise durations using ffmpeg. Use when user asks to create sound effects, write Suno prompts for SFX, trim audio files to target durations, batch process game audio, or normalize sound effects. Triggers on "Suno sound effects", "SFX prompts", "trim audio", "sound effect generation", "game audio", "booster pack sounds", "normalize SFX". Do NOT use for music production, full song generation, or non-SFX audio work.

SKILL.md — Writing Effective Suno v5 Prompts

Overview

Suno v5 has two input fields: a Style Prompt and a Lyrics/Structure Field. The style prompt defines the sound. The structure field defines the shape. Both matter, but they do different jobs. This document covers how to write both for any genre, any mood, any use case.

The Two Fields

Style Prompt

description	Build audio-synchronized visual demos in a single HTML file using WebGL2/GLSL raymarching. Covers SDF-based 3D scenes, multi-pass rendering with bloom, phase-based timeline choreography, and real-time audio-reactive visuals via Web Audio API. Use when asked to create demoscene demos, WebGL raymarching, audio-reactive graphics, music visualizers, or choreographed visual experiences.
