Configure Aab Build

Q: Why use Configure Aab Build on TypingMind?

Because you install it once and use it with any model. Configure Aab Build 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.

Q: How do I install Configure Aab Build in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/khadinakbarlabs/expo-mobile-app-builder/tree/main/skills/configure-aab-build. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Q: Which AI models can use Configure Aab Build?

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.

Q: How many AI models can I use with Configure Aab Build?

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

Q: Is the Configure Aab Build AI skill free?

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

Q: 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.

Q: 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.

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.
1 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by khadinakbarlabs on GitHub. Read the source before you install it.

Installation

Install the Configure Aab Build 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.
https://github.com/khadinakbarlabs/expo-mobile-app-builder/tree/main/skills/configure-aab-build
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/khadinakbarlabs/expo-mobile-app-builder.git /tmp/expo-mobile-app-builder
mkdir -p .claude/skills
cp -r /tmp/expo-mobile-app-builder/skills/configure-aab-build .claude/skills/configure-aab-build

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

Use it in TypingMind

Enable Configure Aab Build 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 Configure Aab Build 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 Configure Aab Build 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.

Configure AAB Build

Build the leanest possible AAB.

app.json + expo-build-properties

json
{
  "expo": {
    "plugins": [
      ["expo-build-properties", {
        "android": {
          "enableProguardInReleaseBuilds": true,
          "enableShrinkResourcesInReleaseBuilds": true,
          "extraProguardRules": "-keep class com.facebook.react.** { *; }"
        }
      }]
    ]
  }
}

What each does

ProGuard/R8 (minify): obfuscates + removes unused code (~30% size reduction)
Shrink Resources: removes unused images/strings (~10-20% reduction)
AAB: Play splits per-device (~30-50% download reduction vs single APK)

Inspect AAB

bash
bundletool build-apks --bundle=app-release.aab --output=app.apks
unzip -l app.apks
# See split APKs by ABI, density, language

Per-device split APK size

bash
bundletool build-apks --bundle=app-release.aab --connected-device --output=app.apks
bundletool get-size total --apks=app.apks
# Shows actual download size for THIS device

ABI filters (smaller for specific architectures)

If you only support arm64 (which is fine for Android 8+ devices):

json
{
  "expo-build-properties": {
    "android": {
      "ndkVersion": "26.1.10909125",
      "abiFilters": ["arm64-v8a"]
    }
  }
}

Drops armeabi-v7a, x86 architectures → ~30% smaller AAB.

WARNING: some emulators are x86. Keep x86_64 if targeting devs.

Image optimization

bash
# Before adding to assets/
# Use WebP instead of PNG (50% smaller)
cwebp -q 80 input.png -o output.webp

ProGuard config rules

Custom rules in proguard-rules.pro:


-keep class com.yourcompany.** { *; }
-keepattributes Signature
-keepattributes *Annotation*

Verify

bash
bundletool get-size total --apks=app.apks --dimensions=ABI,LANGUAGE,SCREEN_DENSITY

Should be <20MB target for indie apps.
