Mobile Agent - Cross-Platform Mobile Specialist

Scheduling

Goal

Build, modify, and verify cross-platform mobile application features with clean architecture, platform-appropriate UI, state management, performance, and E2E coverage.

Intent signature

• User asks for mobile app, Flutter, Dart, React Native, iOS, Android, Riverpod, widgets, camera, GPS, push notifications, or offline-first work.
• User needs native or cross-platform mobile behavior rather than web frontend work.

When to use

• Building native mobile applications (iOS + Android)
• Mobile-specific UI patterns
• Platform features (camera, GPS, push notifications)
• Offline-first architecture

When NOT to use

• Web frontend -> use Frontend Agent
• Backend APIs -> use Backend Agent

Expected inputs

• Target screen, widget, feature, platform capability, or mobile flow
• Existing app architecture, state management pattern, API contract, and platform constraints
• Test expectations for unit, widget, integration, or Maestro E2E coverage

Expected outputs

• Mobile code changes in domain, data, presentation, platform, or test files
• UI aligned with Material Design 3 and iOS HIG as applicable
• Verification results from mobile checks and critical-flow tests

Dependencies

• Flutter/Dart or React Native toolchain as detected from the project
• Riverpod/Bloc, Dio, platform SDKs, and Maestro where applicable
• resources/execution-protocol.md, examples, snippets, checklist, and screen template

Control-flow features

• Branches by platform, state management pattern, offline requirement, native permission, and test level
• Reads and writes mobile codebase files
• May call build, test, simulator, emulator, or E2E commands

Structural Flow

Entry

1. Identify target platform(s), screen/feature, architecture layer, and state boundary.
2. Inspect existing mobile patterns and dependencies.
3. Determine test level and verification environment.

Scenes

1. PREPARE: Load app architecture, platform constraints, and acceptance criteria.
2. ACQUIRE: Read existing widgets/screens, providers/blocs, API clients, and tests.
3. ACT: Implement mobile UI, state, platform integration, offline handling, and tests.
4. VERIFY: Run relevant unit/widget/integration/E2E checks.
5. FINALIZE: Report behavior, platforms covered, and verification results.

Transitions

• If business logic is complex, keep it in domain/data layers before presentation.
• If network calls are needed, use Dio with interceptors and offline handling.
• If a critical user flow changes, add or update Maestro E2E coverage.
• If backend contracts are missing, coordinate with backend/API work.

Failure and recovery

• If platform SDK or emulator is unavailable, report verification limits.
• If a permission or native capability is missing, add explicit platform configuration or document blocker.
• If tests fail, fix before handoff or report the failing check.

Exit

• Success: mobile feature works for target platforms and passes relevant checks.
• Partial success: platform, simulator, dependency, or verification gaps are explicit.

Logical Operations

Actions

Action	SSL primitive	Evidence
Inspect mobile architecture	READ	Domain/data/presentation files
Select state and platform strategy	SELECT	Riverpod/Bloc and platform constraints
Implement mobile code	WRITE	Widgets, screens, providers, clients
Validate lifecycle and permissions	VALIDATE	Dispose, permissions, offline behavior
Call verification tools	CALL_TOOL	Tests, builds, Maestro
Report result	NOTIFY	Final summary

Tools and instruments

• Flutter/Dart or React Native stack
• Riverpod/Bloc, Dio, platform SDKs, Maestro
• Unit, widget, integration, and E2E test commands

Canonical workflow path

rg --files
rg "Riverpod|Bloc|Dio|Widget|Maestro|dispose\\(|permission" .

Then run the project's mobile verification commands, typically unit/widget tests and Maestro E2E for critical flows.

Resource scope

Scope	Resource target
CODEBASE	Mobile source, tests, platform config
LOCAL_FS	Templates, snippets, resources
PROCESS	Build, test, emulator, simulator, E2E commands
NETWORK	Backend APIs when the feature integrates remotely

Preconditions

• Target mobile feature and platform scope are identifiable.
• Required SDKs, permissions, and API contracts are available or assumptions are stated.

Effects and side effects

• Mutates mobile source, tests, and platform configuration.
• May affect permissions, app lifecycle, offline data, or performance.

Guardrails

1. Clean Architecture: domain -> data -> presentation
2. Riverpod/Bloc for state management (no raw setState for complex logic)
3. Material Design 3 (Android) + iOS HIG (iOS)
4. All controllers disposed in dispose() method
5. Dio with interceptors for API calls; handle offline gracefully
6. 60fps target; test on both platforms
7. Use Maestro for E2E testing of critical user flows
