+
+This file provides guidance to coding agents when working with code in this repository.
+
+## Project Overview
+
+Android client library for tracking user events (Nosara/Tracks), A/B testing (ExPlat), and crash logging (Sentry). Published to Automattic's S3 Maven repository. Used internally by Automattic mobile apps. Includes a `sampletracksapp` app module that can be used for manual testing.
+
+## Build Commands
+
+```bash
+./gradlew assembleDebug              # Build all modules
+./gradlew testDebugUnitTest          # Run all unit tests
+./gradlew lintDebug                  # Run lint checks
+./gradlew ktlint                     # Check Kotlin code style (custom task from ktlint.gradle)
+./gradlew ktlintFormat               # Fix Kotlin code style deviations (custom task from ktlint.gradle)
+./gradlew ciktlint                   # Same as ktlint but with checkstyle XML output for CI (custom task from ktlint.gradle)
+./gradlew buildHealth                # Dependency analysis
+./gradlew :experimentation:apiCheck  # Binary compatibility check (`experimentation` module only)
+./gradlew :benchmark:assembleDebugAndroidTest    # Build benchmark instrumented tests
+./gradlew :benchmark:connectedDebugAndroidTest   # Run benchmark instrumented tests on a connected device
+```
+
+To run a single test class:
+
+```bash
+./gradlew :experimentation:testDebugUnitTest --tests "com.automattic.android.experimentation.ExPlatTest"
+./gradlew :crashlogging:testDebugUnitTest --tests "com.automattic.android.tracks.crashlogging.SentryCrashLoggingTest"
+```
+
+**Note:** `gradle.properties` is gitignored. CI copies `gradle.properties-example` before building. Locally, copy it manually if needed: `cp gradle.properties-example gradle.properties`.
+
+## Architecture
+
+Three independently published library modules plus a sample app and benchmark module:
+
+| Module | Artifact | Language | Description |
+|--------|----------|----------|-------------|
+| `AutomatticTracks` | `com.automattic:Automattic-Tracks-Android` | Java + Kotlin | Core event tracking with SQLite storage and background network transmission |
+| `experimentation` | `com.automattic.tracks:experimentation` | Kotlin | ExPlat A/B testing SDK with file-based caching and OkHttp REST client |
+| `crashlogging` | `com.automattic.tracks:crashlogging` | Kotlin | Sentry-based crash logging, performance monitoring, and error tracking |
+| `sampletracksapp` | — | Kotlin | Sample app demonstrating library usage |
+| `benchmark` | — | Kotlin | Performance benchmarking via `androidTest` instrumented tests using `androidx.benchmark` |
+
+### Key architectural details
+
+- **AutomatticTracks** uses a queue-based architecture with background threads for event buffering, DB-to-network transfer, and network transmission. Events expire after 14 days.
+- **experimentation** has `explicitApi()` enabled and uses binary compatibility validation (`apiCheck`). Public API surface is tracked in `experimentation/api/experimentation.api`.
+- **crashlogging** wraps Sentry SDK via `SentryErrorTrackerWrapper` and exposes a `CrashLoggingDataProvider` interface for host apps to supply user/app context.
+- Modules publish independently to S3. No product flavors or build variants.
+
+## Testing Conventions
+
+- **Frameworks:** JUnit 4, AssertJ, Mockito-Kotlin, kotlinx-coroutines-test, MockWebServer
+- **Assertions:** Use AssertJ (`assertThat`), not kotlin.test assertions
+- **Naming:** Backtick-quoted names: `` `given ..., when ..., then ...` ``
+- **Coroutines:** Use `runTest` from `kotlinx.coroutines.test`
+
+## Important Gotchas
+
+- Build files use **Groovy** (`build.gradle`, `settings.gradle`), not Kotlin DSL — except `benchmark/build.gradle.kts` which uses Kotlin DSL
+- Dependency versions are defined as `ext` properties in root `build.gradle`, not a version catalog
+- Lint treats warnings as errors (`warningsAsErrors true`). `AutomatticTracks` uses a lint baseline file
+
+## Publishing
+
+CI publishes on every PR commit and trunk merge:
+- PR: `{pr-number}-{commit-full-sha1}`
+- Trunk merge: `trunk-{commit-full-sha1}`
+- Tag: `{tag-name}`
