# Android Kotlin Compose Development

**Context ladder (smaller load first; full references stay complete):**

1. This file (`SKILL.md`) - routing, stop rules, examples.
2. `references/*-quick.md` when listed below - required/forbidden + section links (~40 lines).
3. One target section in the full `references/*.md` - code samples and checklists only.
4. [INDEX-sections.md](references/INDEX-sections.md) - anchor dump only when quick routing is insufficient.

Forbidden: load [INDEX-sections.md](references/INDEX-sections.md) or an entire multi-thousand-line reference when one section or a quick file covers the task.

Route tasks through the Quick Reference table. When no row matches, or the task needs greenfield bootstrap: [workflows.md](references/workflows.md). Full file list: [INDEX.md](references/INDEX.md).

**Required:**

- **Existing project:** read `settings.gradle.kts`, `gradle/libs.versions.toml`, and the `app` module build file before copying from `assets/` - [dependencies.md](references/dependencies.md#existing-project-brownfield), [modularization.md](references/modularization.md#existing-project-alignment). Stack migrations: [migration.md](references/migration.md).
- **Greenfield:** [workflows.md](references/workflows.md) → "Creating a new project?"
