 ## Architecture
 - **CLI Tool**: Uploads sourcemaps, manages obfuscation symbols, tracks deployments for Raygun.com
 - **Main Entry**: `bin/raygun_cli.dart` - CLI argument parsing and command routing
-- **Commands**: `lib/src/` - Four main command modules: sourcemap, symbols, deployments, proguard
+- **Commands**: `lib/src/` - Five main command modules: sourcemap, symbols, deployments, proguard, dsym
 - **APIs**: Each command has corresponding API client (`*_api.dart`) for Raygun REST API calls
 - **Config**: `config_props.dart` handles arg parsing with env var fallbacks (RAYGUN_APP_ID, RAYGUN_TOKEN, RAYGUN_API_KEY)
 
+### Directory Structure

+lib/src/[command]/
+  ├── [command]_command.dart  # CLI parsing and routing
+  ├── [command]_api.dart      # Raygun API integration
+  └── [command].dart          # Business logic (if complex)
+lib/src/core/                 # Shared utilities (RaygunCommand, RaygunApi builders)
+test/[command]/               # Tests mirror lib structure
+```
+
+### Dependency Flow
+```
+bin/raygun_cli.dart → lib/src/[command]/[command]_command.dart → *_api.dart
+```
+- Commands are stateless; API clients handle HTTP
+- Commands receive API clients via constructor (dependency injection)
+
 ## Code Style
 - **Imports**: Standard library first, then package imports, then relative imports
 - **Naming**: Snake_case for files/dirs, camelCase for variables, PascalCase for classes

 - **Types**: Use explicit types for public APIs, required named parameters preferred
 - **Strings**: Use single quotes, string interpolation with $variable or ${expression}
 - **Comments**: Use /// for public API documentation, avoid inline comments
+
+## Error Handling & Exit Codes
+Standard error handling patterns used throughout:
+- **Exit code 0**: Success
+- **Exit code 1**: Failure (operation didn't succeed)
+- **Exit code 2**: Error (exception or invalid input)
+- Print errors to console before returning/exiting
+- Use `Future<bool>` return type for async operations
+- Chain with `.then()` and `.catchError()` for error handling
+
+Example:
+```dart
+run().then((result) {
+  if (result) {
+    exit(0);
+  } else {
+    exit(2);
+  }
+}).catchError((e) {
+  print('Error: $e');
+  exit(2);
+});
+```
+
+## Command Implementation Patterns
+All commands extend the `RaygunCommand` abstract class:
+
+### Required Implementation
+```dart
+class MyCommand extends RaygunCommand {
+  const MyCommand({required this.api});
+
+  final MyApi api;
+
+  @override
+  String get name => 'mycommand';
+
+  @override
+  ArgParser buildParser() { /* ... */ }
+
+  @override
+  void execute(ArgResults command, bool verbose) { /* ... */ }
+}
+```
+
+### Command Patterns
+- **Help Flag**: Always check for `--help` flag first and exit(0)
+- **Config Loading**: Use `ConfigProp.load()` for app-id, token, api-key (exits if missing)
+- **Subcommands**: Use `ArgParser.addCommand()` (see symbols: upload/list/delete)
+- **Verbose Flag**: Available in all commands (inherited from main parser)
+- **Mandatory Args**: Use `mandatory: true` in ArgParser for required flags
+
+### Example: Subcommands Pattern (symbols command)
+```dart
+ArgParser buildParser() {
+  return ArgParser()
+    ..addOption('app-id')
+    ..addOption('token')
+    ..addCommand('upload')
+    ..addCommand('list')
+    ..addCommand('delete');
+}
+```
+
+## API Client Patterns
+Each command has a corresponding API client:
+
+### Builder Pattern for Requests
+- `RaygunMultipartRequestBuilder` - For file uploads
+- `RaygunPostRequestBuilder` - For JSON POST requests
+
+Example:
+```dart
+final request = RaygunMultipartRequestBuilder(url, 'POST')
+  .addBearerToken(token)
+  .addFile('file', filePath)
+  .addField('version', version)
+  .build();
+```
+
+### API Client Structure
+- Factory method pattern: Use static `.create()` for production instances
+- Return `Future<bool>` to indicate success/failure
+- Print response codes and messages for debugging
+- Handle HTTP responses and errors appropriately
+
+## Testing Patterns & Mock Generation
+
+### Test Structure
+- Tests use `mockito` for mocking API clients
+- Test files mirror `lib/` structure (e.g., `lib/src/symbols/` → `test/symbols/`)
+- Mock files use `.mocks.dart` suffix and are git-tracked
+- Generate mocks with: `dart run build_runner build`
+
+### Test Pattern
+```dart
+// 1. Generate mock classes with @GenerateMocks annotation
+@GenerateMocks([MyApi])
+void main() {
+  group('MyCommand', () {
+    late MockMyApi mockApi;
+
+    setUp(() {
+      mockApi = MockMyApi();
+    });
+
+    test('description', () async {
+      // 2. Setup mock behavior
+      when(mockApi.someMethod()).thenAnswer((_) async => true);
+
+      // 3. Inject mock into command
+      final command = MyCommand(api: mockApi);
+
+      // 4. Execute and verify
+      final result = await command.run(...);
+      expect(result, true);
+    });
+  });
+}
+```
+
+### Mock Regeneration
+- After changing API signatures, run: `dart run build_runner build`
+- Use `watch` mode during development: `dart run build_runner watch`
+
+## Dependency Injection
+
+### Pattern
+- Commands receive API clients via constructor
+- Global command instances use `.create()` factories
+- Tests inject mock API clients
+- Enables testing without hitting real APIs
+
+Example:
+```dart
+// Production usage (in command file)
+SymbolsCommand symbolsCommand = SymbolsCommand(api: SymbolsApi.create());
+
+// Test usage
+final mockApi = MockSymbolsApi();
+final command = SymbolsCommand(api: mockApi);
+```
+
+## CI/CD & Release Workflow
+
+### PR Requirements
+- **Title**: Must follow Conventional Commits (enforced by `.github/workflows/pr.yml`)
+- **Checks**: All must pass - format, analyze, test
+- **Platforms**: Multi-platform builds run automatically (Linux, macOS, Windows)
+
+### Conventional Commits Format
+Examples:
+- `feat: add new command for X`
+- `fix: resolve issue with Y`
+- `chore: update dependencies`
+- `docs: update README`
+
+### Version Management
+**IMPORTANT**: Update BOTH files when releasing:
+1. `pubspec.yaml` - version field
+2. `bin/raygun_cli.dart` - version constant
+
+### Workflows
+- **pr.yml**: Validates PR title format
+- **main.yml**: Runs tests, format check, analysis, and builds binaries for all platforms
+- **release.yml**: On GitHub release, builds and uploads zipped binaries
+
+## Development Workflow
+
+### Local Testing
+```bash
+# Run CLI locally with arguments
+dart run bin/raygun_cli.dart <command> <args>
+
+# Use verbose flag for debug output
+dart run bin/raygun_cli.dart -v sourcemap --help
+
+# Set environment variables for testing
+export RAYGUN_APP_ID=test-app-id
+export RAYGUN_TOKEN=test-token
+export RAYGUN_API_KEY=test-api-key
+```
+
+### Testing Workflow
+1. Write/modify API client code
+2. Add `@GenerateMocks([MyApi])` to test file
+3. Run `dart run build_runner build` to generate mocks
+4. Write tests using mock instances
+5. Run `dart test` to verify
+
+### Build for Distribution
+```bash
+# Compile for current platform
+dart compile exe bin/raygun_cli.dart -o raygun-cli
+
+# Note: Cross-compilation not supported; use CI for other platforms
+```
+
+## Common Gotchas & Best Practices
+
+### Validation Order
+1. Always validate `--help` flag first before parsing other args
+2. `ConfigProp.load()` calls `exit(2)` if required config is missing
+3. Check mandatory args before executing business logic
+
+### File Operations
+- Use `File.existsSync()` before file operations
+- Throw descriptive exceptions if files don't exist
+- Use `.split("/").last` to get filename from path
+
+### Argument Parsing
+- Use `command.wasParsed('flag')` to check if flag was provided
+- Use `command['option']` to get option value
+- Use `command.command?.name` to get subcommand name
+
+### Async Patterns
+- Prefer `.then()` and `.catchError()` over try/catch for CLI commands
+- Always handle errors gracefully with user-friendly messages
+- Use `Future<bool>` for operations that can succeed or fail
+
+### String Conventions
+- Always use single quotes for strings (Dart convention)
+- Use string interpolation: `'Value: $variable'` or `'Value: ${expression}'`
+
+## Quick Reference
+
+### Command Examples
+```bash
+# Sourcemap upload (Flutter)
+dart run bin/raygun_cli.dart sourcemap -p flutter \
+  --uri=https://example.com/main.dart.js \
+  --app-id=XXX --token=YYY

+```
+
+## Known TODOs & Future Improvements
+- Config file support (.raygun.yaml or similar) - see `lib/src/config_props.dart:9`
+- NodeJS sourcemap platform support (currently stubbed in sourcemap command)
+- System package manager installations (brew, apt, etc.)
+
+## Troubleshooting
+
+### Mock Generation Issues
+- Ensure `@GenerateMocks` annotation is present in test file
+- Run `dart pub get` to ensure dependencies are installed
+- Clean and rebuild: `dart run build_runner clean && dart run build_runner build`
+
+### Build Issues
+- Ensure Dart SDK version matches `pubspec.yaml` requirement (^3.5.0)
+- Run `dart pub get` to update dependencies
+- Check that version in `bin/raygun_cli.dart` matches `pubspec.yaml`
+
+### Test Failures
+- Verify mocks are regenerated after API changes
+- Check that mock behavior is properly stubbed with `when()`
+- Ensure async tests use `async/await` or return Future
