Stac Screen Builder

Overview

Use this skill to convert feature requirements into maintainable Stac DSL screens and theme definitions.

Workflow

  1. Translate user requirements into route names, states, and actions.
  2. Select widgets using references/widget-selector.md.
  3. Select actions using references/action-recipes.md.
  4. Apply style patterns from references/style-recipes.md.
  5. Apply route semantics from references/navigation-patterns.md.
  6. Scaffold files using scripts when requested.

Required Inputs

  • Target screen name (snake_case recommended).
  • Desired interactions (navigation, network, forms, state changes).
  • Whether a theme reference is needed.

Output Contract

  • Return valid Stac DSL snippets with @StacScreen or @StacThemeRef.
  • Keep generated screen names stable and explicit.
  • Use built-in Stac widgets/actions first, then custom extensions if needed.

References

  • Read references/widget-selector.md to choose layout and interactive widgets.
  • Read references/action-recipes.md for navigation/form/network/state actions.
  • Read references/style-recipes.md for color, spacing, and text style patterns.
  • Read references/navigation-patterns.md for stack-safe navigation actions.

Scripts

  • scripts/new_screen.py --screen-name <name> --out-dir <path> [--with-navigation]
  • scripts/new_theme_ref.py --theme-name <name> --out-file <path>

Templates

  • assets/templates/screen.dart.tmpl
  • assets/templates/theme_ref.dart.tmpl
