Skill: LiteRT Compiled Model Migration SKILL

Description

This skill guides an AI agent to rapidly migrate an Android application from legacy TensorFlow Lite (TFLite) to the modern LiteRT CompiledModel API v2.1.6 in Open Source GitHub repositories. It prioritizes a high-speed, 1st-pass "Like for Like" baseline migration with automated self-testing, and encourages advanced performance upgrades including True Asynchronous Execution (runAsync), Zero-Copy I/O Buffer Management, and NPU JIT compilation.

0. Automatic Discovery & Upfront Planning

Before writing code, the agent MUST inspect the project workspace and present the upfront planning interview to align migration parameters:

A. Automatic Workspace & Toolchain Discovery

The agent must automatically inspect the repository structure:

  1. Ecosystem & Build Engine:
    • Gradle Build System: Detected by build.gradle, build.gradle.kts, or settings.gradle. -> Enable Gradle & GitHub PR Workflow.
  2. Language & JNI Toolchain:
    • Native C++ / NDK: Detected if CMakeLists.txt, Android.mk, or *.cpp files exist. -> Enable C++ / JNI Migration Rules.
    • Pure Kotlin / Java: Default to JVM / Android SDK Migration Rules.

[!TIP] Speed Optimization (Subagent Routing): When orchestrating subagents, the agent MUST default to DeepCoderLite (or DeepInvestigatorLite) to guarantee a 2–5 minute migration turnaround. Do NOT invoke heavy multi-layer DeepCoder synthesis unless the codebase features complex custom C++ NDK/CMake build systems.

B. Upfront User Interview (Questions Asked Prior to Migration)

The agent must present the following review options to the user:

Before initiating the LiteRT Compiled Model Migration, please confirm your project preferences:

1. Model Workload & Domain:
   What type of data does this application process?
   - [A] Vision (Images / Video / Camera Feeds) -> Enables Zero-Copy AHardwareBuffer / direct ByteBuffer recipes.
   - [B] Audio (Speech / Sound Classification) -> Enables streaming FloatArray or ByteBuffer recipes.
   - [C] Text / NLP / GenAI -> Enables tokenized tensor buffer recipes.

2. LiteRT Runtime Target SDK:
   Which SDK distribution target should the project use?
   - [A] Standalone / Bundled LiteRT V2 (com.google.ai.edge.litert:litert) [Default]
         -> Bundles LiteRT runtime inside the APK for offline self-contained operation.
   - [B] LiteRT-in-GMSCore (com.google.android.gms:play-services-litert) [Experimental / Future Release]
         -> Dynamically requests runtime from Google Play Services, saving ~5 MB APK binary bloat.

3. Hardware Acceleration & Conditional INT8 Quantization:
   Do you want to enable NPU hardware acceleration via JIT on-device compilation?
   - [A] Yes (Recommended - replaces deprecated NNAPI) [Default]
         * If the app uses a Float32 model: Would you like to generate an INT8 integer-quantized model via AI Edge Quantizer for peak NPU speed, or run the original Float32 model?
           -> Option A.1: Convert to INT8 (Generates model_int8.tflite for NPU matrix engines) [Default]
           -> Option A.2: Keep Float32 (Runs baseline float model directly on NPU)
   - [B] No (GPU and CPU acceleration only)

4. Encouraged Performance Upgrades:
   Should the agent upgrade the calling code to use LiteRT's advanced features?
   - [A] Yes (Enable True Async Execution runAsync & Zero-Copy I/O Buffers) [Default]
   - [B] No (Keep strict 1-to-1 synchronous baseline execution)

5. Automated Pull Request Provisioning:
   Should the agent automatically stage, commit, and create a GitHub PR when self-testing passes?
   - [A] Yes [Default] (Attaches verification test logs and before/after summary diff)
   - [B] No (Keep changes local in current working branch)

[!IMPORTANT] Mandatory Support Library Removal: The agent must inform the user that all legacy org.tensorflow.lite.support libraries (ImageProcessor, ResizeOp, NormalizeOp, etc.) will be completely removed and replaced with direct LiteRT buffer APIs and native preprocessing. This is mandatory to unlock zero-copy speed and API compatibility.

1. Phase 1: "Like for Like" Baseline Migration (1st Pass Success)

Phase 1 prioritizes functional equivalence, fast compilation, and immediate 1st pass self-test success.

Step 1: Clean & Modernize Dependencies

Inspect libs.versions.toml and build.gradle.kts:

  • Remove Legacy & Deprecated:
    • org.tensorflow:tensorflow-lite
    • org.tensorflow:tensorflow-lite-gpu
    • org.tensorflow:tensorflow-lite-support
    • org.tensorflow:tensorflow-lite-select-tf-ops (Legacy Flex Delegate — see Deprecated API Remediation below)
  • Replace TFLite Support Image Preprocessing: If the application uses legacy TFLite Support (org.tensorflow.lite.support.image.ImageProcessor, ResizeOp, NormalizeOp), completely remove the Support library dependency. Replace image scaling with androidx.core.graphics.scale (or Bitmap.createScaledBitmap) and replace normalization with direct memory-mapped pixel buffer writing (ByteBuffer.allocateDirect / AHardwareBuffer).
  • Add Modern LiteRT:
    • Standalone: implementation 'com.google.ai.edge.litert:litert:2.1.6'
    • GMSCore: implementation 'com.google.android.gms:play-services-litert:16.0.0'
  • IDE Portability: Remove hardcoded org.gradle.java.home from gradle.properties and exclude local.properties.
  • Kotlin Compiler DSL: Use top-level kotlin { compilerOptions { ... } } outside android { ... }.
Step 2: Deprecated API & Delegate Remediation

The agent must audit and replace all deprecated delegate APIs:

  1. NNAPI Delegate (NnApiDelegate, NnApiDelegate.Options, setUseNNAPI(true)):

    • Status: Deprecated in Android 12+ and removed in LiteRT V2.
    • Remediation: Remove org.tensorflow.lite.delegates.NnApiDelegate imports. Replace with CompiledModel.Options(Accelerator.NPU) combined with Environment.create(BuiltinNpuAcceleratorProvider(context), envOptions). Implement an explicit NPU -> GPU -> CPU fallback cascade to handle non-NPU hardware smoothly.

  2. Flex Delegate (SelectDelegate, org.tensorflow.lite.flex, select-tf-ops):

    • Status: Deprecated and incompatible with LiteRT V2 zero-copy and NPU acceleration (bloats APK size by ~30 MB with full TF runtime).
    • Remediation:
      • Remove org.tensorflow:tensorflow-lite-select-tf-ops from build.gradle.kts.
      • Audit model ops using litert_gpu_toolkit or Flatbuffer inspection to identify unsupported Flex ops.
      • Replace Flex ops by re-exporting the model via modern LiteRT converters (litert_torch / LiteRT-torch or ai_edge_quantizer), or implement native LiteRT custom ops via litert/cc/litert_custom_op.h if custom C++ math is required.
Step 3: Native Build Toolchain (CMakeLists.txt / NDK)

For native C++ modules, update CMakeLists.txt:

# Replace legacy tensorflowlite_jni with LiteRt
find_library(log-lib log)
find_library(android-lib android)

target_link_libraries(your_native_lib
    LiteRt
    litert_jni
    ${log-lib}
    ${android-lib}
)
Step 4: API & Lifecycle Refactoring (Rewrite Initialization & Dynamic Signatures)

[!IMPORTANT] Never Simple Swap: Do NOT merely perform a search-and-replace of the Interpreter class. Rewrite the model initialization logic to instantiate CompiledModel with an explicit hardware fallback cascade (NPU -> GPU -> CPU). When NPU is selected, prioritize NPU JIT compilation by instantiating an explicit Environment object (Environment.create(BuiltinNpuAcceleratorProvider(context), envOptions)) configured with DispatchLibraryDir and CompilerPluginLibraryDir pointing to context.applicationInfo.nativeLibraryDir.

Legacy TFLite APIModern LiteRT V2 Drop-in Replacement
org.tensorflow.lite.Interpretercom.google.ai.edge.litert.CompiledModel
Interpreter(modelFile, options)CompiledModel.create(modelPath, options, env) (via NPU Environment & Fallback Cascade)
interpreter.run(input, output)compiledModel.run(inputBuffers, outputBuffers)
GpuDelegate() / NnApiDelegate()CompiledModel.Options(Accelerator.GPU / NPU / CPU)
org.tensorflow.lite.flex.FlexDelegateNative LiteRT op / CompiledModel.Options(Accelerator.NPU / GPU)
interpreter.getInputTensor(0)compiledModel.getInputTensorType("args_0") (Fallback: "input_0")
ImageProcessor.Builder().add(ResizeOp(...)).build()androidx.core.graphics.scale(width, height) / Bitmap.createScaledBitmap
#include "tensorflow/lite/interpreter.h"#include "litert/cc/litert_compiled_model.h"
#include "tensorflow/lite/c/c_api.h"#include "litert/c/litert_compiled_model.h"
Step 5: Two-Stage Fast Verification Gate (Karpathy Self-Test)

To maximize execution speed:

  • Stage 1 (Refactoring Gate): Run fast incremental compile checks only (./gradlew compileDebugKotlin or ./gradlew assembleDebug) to verify syntax in seconds.
  • Stage 2 (Final Verification Gate): Copy templates/MigrationValidationTest.kt into androidTest/ and execute full packaging (./gradlew assembleDebug assembleDebugAndroidTest and ./gradlew testDebugUnitTest).

2. Phase 2: Encouraged Performance Upgrades

Once Phase 1 compiles and passes self-testing, the agent applies high-value performance features:

Upgrade 2.A: True Asynchronous Execution (runAsync)

Replace blocking UI thread inference with LiteRT's non-blocking async execution:

// Non-blocking async execution for smooth 60/120 FPS UI viewfinders
compiledModel.runAsync(inputBuffers, outputBuffers, object : CompiledModel.AsyncCallback {
    override fun onComplete(outputBuffers: Array<TensorBuffer>) {
        // Handle output tensor results on completion thread
        val results = outputBuffers[0].readFloat()
        updateUI(results)
    }
    override fun onError(error: Throwable) {
        Log.e("LiteRT", "Async inference failed", error)
    }
})
Upgrade 2.B: Efficient Zero-Copy I/O Buffer Management

Bypass intermediate JVM array copying (FloatArray, IntArray) by using hardware texture buffers and direct memory-mapped ByteBuffer streams:

// Vision Zero-Copy: Direct AHardwareBuffer texture interop
val inputTensorBuffer = TensorBuffer.createFromAhwb(hardwareBuffer)
compiledModel.run(arrayOf(inputTensorBuffer), outputBuffers)

// Cleanup lifecycle
inputTensorBuffer.close()
outputBuffers.forEach { it.close() }
Upgrade 2.C: NPU JIT Acceleration & Conditional INT8 Quantization
  1. Conditional INT8 Quantization: If NPU JIT is selected and the user opted in, run AI Edge Quantizer (aeq) to generate model_int8.tflite in assets/: 
    from ai_edge_quantizer import Quantizer, QuantizationConfig, QuantizationType
qt = Quantizer("src/main/assets/model.tflite")
qt.quantize_model(QuantizationConfig(weight_type=QuantizationType.INT8, activation_type=QuantizationType.INT8))
qt.export_model("src/main/assets/model_int8.tflite")
  2. NPU JIT Runtime Bundling: Package vendor shared libraries in app/src/main/jniLibs/arm64-v8a/ (libLiteRtDispatch_Qualcomm.so, libQnnHtp.so, etc.). Check local LITERT_JIT_CACHE_DIR before network downloads.
  3. Qualcomm FastRPC Permission: Declare <uses-native-library android:name="libcdsprpc.so" android:required="false" /> inside <application> in AndroidManifest.xml.
  4. Environment Dispatch & Fallback Cascade: Pass `DispatchLibraryD

---

## 1. Phase 1: "Like for Like" Baseline Migration (1st Pass Success)

Phase 1 prioritizes functional equivalence, fast compilation, and immediate 1st pass self-test success.

### Step 1: Clean & Modernize Dependencies

Inspect `libs.versions.toml` and `build.gradle.kts`:
* **Remove Legacy & Deprecated**:
  * `org.tensorflow:tensorflow-lite`
  * `org.tensorflow:tensorflow-lite-gpu`
  * `org.tensorflow:tensorflow-lite-support`
  * `org.tensorflow:tensorflow-lite-select-tf-ops` *(Legacy Flex Delegate — see Deprecated API Remediation below)*
* **Replace TFLite Support Image Preprocessing**: If the application uses legacy TFLite Support (`org.tensorflow.lite.support.image.ImageProcessor`, `ResizeOp`, `NormalizeOp`), **completely remove the Support library dependency**. Replace image scaling with `androidx.core.graphics.scale` (or `Bitmap.createScaledBitmap`) and replace normalization with direct memory-mapped pixel buffer writing (`ByteBuffer.allocateDirect` / `AHardwareBuffer`).
* **Add Modern LiteRT**:
  * *Standalone*: `implementation 'com.google.ai.edge.litert:litert:2.1.6'`
  * *GMSCore*: `implementation 'com.google.android.gms:play-services-litert:16.0.0'`
* **IDE Portability**: Remove hardcoded `org.gradle.java.home` from `gradle.properties` and exclude `local.properties`.
* **Kotlin Compiler DSL**: Use top-level `kotlin { compilerOptions { ... } }` outside `android { ... }`.

### Step 2: Deprecated API & Delegate Remediation

The agent must audit and replace all deprecated delegate APIs:

1. **NNAPI Delegate (`NnApiDelegate`, `NnApiDelegate.Options`, `setUseNNAPI(true)`)**:
   * **Status**: Deprecated in Android 12+ and removed in LiteRT V2.
   * **Remediation**: Remove `org.tensorflow.lite.delegates.NnApiDelegate` imports. Replace with `CompiledModel.Options(Accelerator.NPU)` combined with `Environment.create(BuiltinNpuAcceleratorProvider(context), envOptions)`. Implement an explicit `NPU -> GPU -> CPU` fallback cascade to handle non-NPU hardware smoothly.

2. **Flex Delegate (`SelectDelegate`, `org.tensorflow.lite.flex`, `select-tf-ops`)**:
   * **Status**: Deprecated and incompatible with LiteRT V2 zero-copy and NPU acceleration (bloats APK size by ~30 MB with full TF runtime).
   * **Remediation**:
     * Remove `org.tensorflow:tensorflow-lite-select-tf-ops` from `build.gradle.kts`.
     * Audit model ops using `litert_gpu_toolkit` or Flatbuffer inspection to identify unsupported Flex ops.
     * Replace Flex ops by re-exporting the model via modern LiteRT converters (`litert_torch` / `LiteRT-torch` or `ai_edge_quantizer`), or implement native LiteRT custom ops via `litert/cc/litert_custom_op.h` if custom C++ math is required.

### Step 3: Native Build Toolchain (`CMakeLists.txt` / NDK)
For native C++ modules, update `CMakeLists.txt`:
```cmake
# Replace legacy tensorflowlite_jni with LiteRt
find_library(log-lib log)
find_library(android-lib android)

target_link_libraries(your_native_lib
    LiteRt
    litert_jni
    ${log-lib}
    ${android-lib}
)
```

### Step 4: API & Lifecycle Refactoring (Rewrite Initialization & Dynamic Signatures)

> [!IMPORTANT]
> **Never Simple Swap**: Do **NOT** merely perform a search-and-replace of the `Interpreter` class. Rewrite the model initialization logic to instantiate `CompiledModel` with an explicit hardware fallback cascade (`NPU -> GPU -> CPU`). When NPU is selected, prioritize NPU JIT compilation by instantiating an explicit `Environment` object (`Environment.create(BuiltinNpuAcceleratorProvider(context), envOptions)`) configured with `DispatchLibraryDir` and `CompilerPluginLibraryDir` pointing to `context.applicationInfo.nativeLibraryDir`.

| Legacy TFLite API | Modern LiteRT V2 Drop-in Replacement |
|---|---|
| `org.tensorflow.lite.Interpreter` | `com.google.ai.edge.litert.CompiledModel` |
| `Interpreter(modelFile, options)` | `CompiledModel.create(modelPath, options, env)` *(via NPU Environment & Fallback Cascade)* |
| `interpreter.run(input, output)` | `compiledModel.run(inputBuffers, outputBuffers)` |
| `GpuDelegate()` / `NnApiDelegate()` | `CompiledModel.Options(Accelerator.GPU / NPU / CPU)` |
| `org.tensorflow.lite.flex.FlexDelegate` | Native LiteRT op / `CompiledModel.Options(Accelerator.NPU / GPU)` |
| `interpreter.getInputTensor(0)` | `compiledModel.getInputTensorType("args_0")` (Fallback: `"input_0"`) |
| `ImageProcessor.Builder().add(ResizeOp(...)).build()` | `androidx.core.graphics.scale(width, height)` / `Bitmap.createScaledBitmap` |
| `#include "tensorflow/lite/interpreter.h"` | `#include "litert/cc/litert_compiled_model.h"` |
| `#include "tensorflow/lite/c/c_api.h"` | `#include "litert/c/litert_compiled_model.h"` |

### Step 5: Two-Stage Fast Verification Gate (Karpathy Self-Test)
To maximize execution speed:
* **Stage 1 (Refactoring Gate)**: Run fast incremental compile checks only (`./gradlew compileDebugKotlin` or `./gradlew assembleDebug`) to verify syntax in seconds.
* **Stage 2 (Final Verification Gate)**: Copy `templates/MigrationValidationTest.kt` into `androidTest/` and execute full packaging (`./gradlew assembleDebug assembleDebugAndroidTest` and `./gradlew testDebugUnitTest`).

## 2. Phase 2: Encouraged Performance Upgrades

Once Phase 1 compiles and passes self-testing, the agent applies high-value performance features:

### Upgrade 2.A: True Asynchronous Execution (`runAsync`)
Replace blocking UI thread inference with LiteRT's non-blocking async execution:
```kotlin
// Non-blocking async execution for smooth 60/120 FPS UI viewfinders
compiledModel.runAsync(inputBuffers, outputBuffers, object : CompiledModel.AsyncCallback {
    override fun onComplete(outputBuffers: Array<TensorBuffer>) {
        // Handle output tensor results on completion thread
        val results = outputBuffers[0].readFloat()
        updateUI(results)
    }
    override fun onError(error: Throwable) {
        Log.e("LiteRT", "Async inference failed", error)
    }
})
```

### Upgrade 2.B: Efficient Zero-Copy I/O Buffer Management
Bypass intermediate JVM array copying (`FloatArray`, `IntArray`) by using hardware texture buffers and direct memory-mapped `ByteBuffer` streams:
```kotlin
// Vision Zero-Copy: Direct AHardwareBuffer texture interop
val inputTensorBuffer = TensorBuffer.createFromAhwb(hardwareBuffer)
compiledModel.run(arrayOf(inputTensorBuffer), outputBuffers)

// Cleanup lifecycle
inputTensorBuffer.close()
outputBuffers.forEach { it.close() }
```

### Upgrade 2.C: NPU JIT Acceleration & Conditional INT8 Quantization
1. **Conditional INT8 Quantization**: If NPU JIT is selected and the user opted in, run AI Edge Quantizer (`aeq`) to generate `model_int8.tflite` in `assets/`:
   ```python
   from ai_edge_quantizer import Quantizer, QuantizationConfig, QuantizationType
   qt = Quantizer("src/main/assets/model.tflite")
   qt.quantize_model(QuantizationConfig(weight_type=QuantizationType.INT8, activation_type=QuantizationType.INT8))
   qt.export_model("src/main/assets/model_int8.tflite")
   ```
2. **NPU JIT Runtime Bundling**: Package vendor shared libraries in `app/src/main/jniLibs/arm64-v8a/` (`libLiteRtDispatch_Qualcomm.so`, `libQnnHtp.so`, etc.). Check local `LITERT_JIT_CACHE_DIR` before network downloads.
3. **Qualcomm FastRPC Permission**: Declare `<uses-native-library android:name="libcdsprpc.so" android:required="false" />` inside `<application>` in `AndroidManifest.xml`.
4. **Environment Dispatch & Fallback Cascade**: Pass `DispatchLibraryD
