Routing Logic

When a task arrives:

Jetpack Compose? → jetpack-compose
Android Navigation? → compose-navigation
Camera/CameraX? → camerax
AGP/Gradle upgrade? → agp-9-upgrade
App size/R8? → r8-analyzer
Android profiling? → android-profiler
Sign-in/Identity? → identity
Play Store? → play
Flutter new app? → flutter-create-app
Flutter widget? → flutter-widget-guide
Flutter state? → flutter-state-management
Flutter test? → flutter-add-test
Flutter debug? → flutter-fix-bug
Dart package? → dart-create-package
Dart test? → dart-add-unit-test

Execution Pattern

1. Announce: "Routing to [skill-name]..."
2. Load: Read the SKILL.md from the path in the catalog
3. Execute: Follow the skill's instructions
4. Cite: Reference the skill in the response

Quick Reference

Task	Route To

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.

Routing Logic

When a task arrives:

Jetpack Compose? → jetpack-compose
Android Navigation? → compose-navigation
Camera/CameraX? → camerax
AGP/Gradle upgrade? → agp-9-upgrade
App size/R8? → r8-analyzer
Android profiling? → android-profiler
Sign-in/Identity? → identity
Play Store? → play
Flutter new app? → flutter-create-app
Flutter widget? → flutter-widget-guide
Flutter state? → flutter-state-management
Flutter test? → flutter-add-test
Flutter debug? → flutter-fix-bug
Dart package? → dart-create-package
Dart test? → dart-add-unit-test

Execution Pattern

1. Announce: "Routing to [skill-name]..."
2. Load: Read the SKILL.md from the path in the catalog
3. Execute: Follow the skill's instructions
4. Cite: Reference the skill in the response

Quick Reference

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
