Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

android-native-dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 884 lines — stays where its author put it; the contents beside it link to each section on GitHub.

1. Project Scenario Assessment

Before starting development, assess the current project state:

Scenario Characteristics Approach
Empty Directory No files present Full initialization required, including Gradle Wrapper
Has Gradle Wrapper gradlew and gradle/wrapper/ exist Use ./gradlew directly for builds
Android Studio Project Complete project structure, may lack wrapper Check wrapper, run gradle wrapper if needed
Incomplete Project Partial files present Check missing files, complete configuration

Key Principles:

  • Before writing business logic, ensure ./gradlew assembleDebug succeeds
  • If gradle.properties is missing, create it first and configure AndroidX

1.1 Required Files Checklist

MyApp/
├── gradle.properties          # Configure AndroidX and other settings
├── settings.gradle.kts

2. Project Configuration

2.1 gradle.properties

# Required configuration
android.useAndroidX=true
android.enableJetifier=true

# Build optimization
org.gradle.parallel=true
kotlin.code.style=official

# JVM memory settings (adjust based on project size)
# Small projects: 2048m, Medium: 4096m, Large: 8192m+
# org.gradle.jvmargs=-Xmx4096m -Dfile.encoding=UTF-8

Note: If you encounter OutOfMemoryError during build, increase -Xmx value. Large projects with many dependencies may require 8GB or more.

2.2 Dependency Declaration Standards

dependencies {
    // Use BOM to manage Compose versions
    implementation(platform("androidx.compose:compose-bom:2024.02.00"))
    implementation("androidx.compose.ui:ui")
    implementation("androidx.compose.material3:material3")
    
    // Activity & ViewModel
    implementation("androidx.activity:activity-compose:1.8.2")
    implementation("androidx.lifecycle:lifecycle-viewmodel-compose:2.7.0")
}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
