Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
3 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by HoangNguyen0403 on GitHub. Read the source before you install it.

Installation

Install the Android Navigation 3 AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/HoangNguyen0403/agent-skills-standard.git /tmp/agent-skills-standard
mkdir -p .claude/skills
cp -r /tmp/agent-skills-standard/skills/android/android-navigation-3 .claude/skills/android-navigation-3

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Android Navigation 3 in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Android Navigation 3 on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Android Navigation 3 is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Jetpack Navigation 3

Priority: P1 (HIGH)

Guide for implementing and migrating to Navigation 3 in Jetpack Compose.

Core concepts

Navigation 3 replaces the previous NavHost/NavController pattern with a simpler, state-driven approach:

Routes are Kotlin data objects/classes (not strings).
Back stack is a plain mutableStateListOf<Any>.
NavDisplay renders the current route based on a lambda.

Basic usage

kotlin
val backStack = remember { mutableStateListOf<Any>(RouteHome) }

NavDisplay(
    backStack = backStack,
    onBack = { backStack.removeLastOrNull() },
    entryProvider = { key ->
        when (key) {
            is RouteHome -> NavEntry(key) { HomeScreen(onNavigate = { backStack.add(it) }) }
            is RouteDetail -> NavEntry(key) { DetailScreen(key.id) }
            else -> error("Unknown route: $key")
        }
    }
)

Migration from Navigation 2

See migration guide for step-by-step conversion from NavHost/NavController to NavDisplay.

Key changes:

Replace string routes with data objects/classes.
Replace NavHost with NavDisplay.
Replace NavController.navigate() with direct list manipulation.
Replace navArgument with data class properties.

Common patterns

See recipes for code examples:

Basic navigation with arguments
Bottom navigation with multiple backstacks
Deep links (basic and with synthetic backstack)
Dialogs and bottom sheets
Conditional navigation (auth flows)
Returning results between screens
Modularized navigation with Hilt or Koin

Verification

Routes are data objects/classes, no string-based routing.
Back stack is a mutableStateListOf<Any>.
NavDisplay handles all routes in entryProvider.
./gradlew build succeeds.

Anti-Patterns

No string-based routes: Use Kotlin data objects/classes for type safety.
No NavController for new projects: Use NavDisplay with a state list.
No remember { navController() }: Navigation 3 doesn't use NavController.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Android Navigation 3 AI skill do?

Why use Android Navigation 3 on TypingMind?

Because you install it once and use it with any model. Android Navigation 3 is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Android Navigation 3 in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/HoangNguyen0403/agent-skills-standard/tree/develop/skills/android/android-navigation-3. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Android Navigation 3?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Android Navigation 3?

As many as you like. As long as a model supports skills, you can use Android Navigation 3 with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Android Navigation 3 AI skill free?

Yes. It is published on GitHub by HoangNguyen0403 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
