🔒 Repo-maintenance skill. It exists to help maintain flutter/genui itself — it's only useful if you contribute code to that project.

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.

name: genui-helper description: > Development helper for the GenUI repository. Use this skill when the user asks about GenUI workflows, running tests, creating components, finding A2UI or Dart references, or adhering to repository standards.

GenUI Development Helper

This skill provides workflows and best practices specific to the genui repository.

Workflows

1. Running Tests and Fixes

The repository uses a custom tool to run tests, apply fixes, and format code before committing. It should typically only be run before committing, since it is inefficient and slow to run it on every change.

It will run dart fix --apply, dart format, and flutter test on all packages in the repository.

Command:

dart run tool/test_and_fix/bin/test_and_fix.dart

When to use:

  • Before committing changes, to ensure project health.
  • Instead of running flutter test manually for each project in the repo.

2. Creating a New Component in the genui package

When creating a new UI component in genui:

  1. Location: Place component files in packages/genui/lib/src/components/.
  2. Inheritance: Components must extend UiComponent.
  3. A2UI Compliance: Ensure the component matches the A2UI specification.
  4. Documentation: Follow strict Dart documentation standards.

3. Updating Documentation

  • Documentation source of truth is in docs/.
  • Use mkdocs context if mentioned, but primarily edit the markdown files directly.
  • Ensure strict adherence to "Natural Writing" standards (no AI-isms).

Key Constants & Patterns

  • Current A2UI Version: v0.9
  • State Management: Uses SurfaceController from genui.
