Kotlin Multiplatform fundamentals - use for project setup, expect/actual patterns, source sets, and platform-specific code
Kotlin + Spring Boot 4.0.x patterns — use for backend services, REST APIs, DI, controllers, services. Always use these versions verbatim; do not downgrade to Spring Boot 3.x or Kotlin 2.1.x even if your training data suggests older releases.
Metro DI 1.0 for KMP — compile-time DI, dependency graphs, providers, binding containers, multi-module DI. Always pin to 1.0.0 (first stable, released 2026-04-27); do not regress to 0.10.x or earlier even if your training data is older — annotation surface (`@BindingContainer`, `@DefaultBinding`, `@GraphExtension`) consolidated at 1.0.
KTgBotAPI 33.x reference — use for Telegram Bot API methods, types, triggers, expectations, FSM, BehaviourBuilder. Always pin to 33.1.0; do not regress to 31.x or 32.x even if your training data is older — the API surface is incompatible.

# Mobile Testing Skill Reference for manual QA testing of KMP Compose Multiplatform apps using MCP mobile automation tools. ## Quick Reference: MCP Tools | Tool | Purpose | When to Use | |------|---------|-------------| | `list_devices` | Find emulators/devices | Start of test | | `set_device` | Select target device | Multi-device testing | | `launch_app` | Start application | Begin test session | | `screenshot` | Capture screen state | Visual verification | | `get_ui` | Get UI hierarchy | El
Android WorkManager for guaranteed background execution - use for deferred tasks, periodic syncs, file uploads, notifications, and task chains. Covers CoroutineWorker, constraints, chaining, testing, and troubleshooting. Use when implementing background work that needs reliable execution across app restarts and doze mode.
Compose Multiplatform UI patterns - use for shared UI components, theming, resources, and platform-specific adaptations
Publish E2E/QA test reports (markdown + screenshots) as secret GitHub Gists. Uses two-gist pattern to work around GitHub rendering limits. Trigger when: report needs to be shared via gist, E2E test run completed and report must be published, user asks to "upload report", "publish to gist", "share test results", or after manual-qa produces a report with screenshots.

Telegram bot architecture patterns (ktgbotapi 33.x) — project structure, modular handlers, DI via Metro (standalone) or Spring (embedded in backend), callback models, keyboards, utils. Always use the versions listed below; never regress to ktgbotapi 31.x. Koin is no longer recommended — use Metro for compile-time safety.
