Configures Flutter Driver for app interaction and converts MCP actions into permanent integration tests. Use when adding integration testing to a project, exploring UI components via MCP, or automating user flows with the integrationtest package.
Skill Claude CodeCodex
Adds interactive widget previews to the project using the previews.dart system. Use when creating new UI components or updating existing screens to ensure consistent design and interactive testing.
Skill Claude CodeCodex
Implement a component-level test using WidgetTester to verify UI rendering and user interactions (tapping, scrolling, entering text). Use when validating that a specific widget displays correct data and responds to events as expected.
Skill Claude CodeCodex
Architects a Flutter application using the recommended layered approach (UI, Logic, Data). Use when structuring a new project or refactoring for scalability.
Skill Claude CodeCodex
Use LayoutBuilder, MediaQuery, or Expanded/Flexible to create a layout that adapts to different screen sizes. Use when you need the UI to look good on both mobile and tablet/desktop form factors.
Skill Claude CodeCodex
Fixes Flutter layout errors (overflows, unbounded constraints) using Dart and Flutter MCP tools. Use when addressing "RenderFlex overflowed", "Vertical viewport was given unbounded height", or similar layout issues.
Skill Claude CodeCodex
Create model classes with fromJson and toJson methods using dart:convert. Use when manually mapping JSON keys to class properties for simple data structures.
Skill Claude CodeCodex
Configure MaterialApp.router using a package like gorouter for advanced URL-based navigation. Use when developing web applications or mobile apps that require specific deep linking and browser history support.
Skill Claude CodeCodex
Add flutterlocalizations and intl dependencies, enable "generate true" in pubspec.yaml, and create an l10n.yaml configuration file. Use when initializing localization support for a new Flutter project.
Skill Claude CodeCodex
Use the http package to execute GET, POST, PUT, or DELETE requests. Use when you need to fetch from or send data to a REST API.
Command Claude Code

Command Claude Code
Archive a completed change in the experimental workflow.
Command Claude Code
Enter explore mode - think through ideas, investigate problems, clarify requirements.
Command Claude Code
Propose a new change - create it and generate all artifacts in one step.
Skill Claude CodeCodex
Implement tasks from an OpenSpec change. Use when the user wants to start implementing, continue implementation, or work through tasks.
Skill Claude CodeCodex
Archive a completed change in the experimental workflow. Use when the user wants to finalize and archive a change after implementation is complete.
Skill Claude CodeCodex
Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
Skill Claude CodeCodex
Propose a new change with all artifacts generated in one step. Use when the user wants to quickly describe what they want to build and get a complete proposal with design, specs, and tasks ready for implementation.
Skill Claude CodeCodex
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
Skill Claude CodeCodex
Generate a custom checklist for the current feature based on user requirements.
Skill Claude CodeCodex
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
Skill Claude CodeCodex
Create or update the project constitution from interactive or provided principle inputs.
Skill Claude CodeCodex
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
Skill Claude CodeCodex
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
