Details and examples are moved to the `references/` docs and `templates/` examples in this skill: - Detailed repository & networking guidance: [references/datasource.md](references/datasource.md) - Model & json_serializable guidance: [references/model.md](references/model.md) - Working code templates: [templates/](templates/) Rename guidance - If an application only uses a remote source, prefer naming the component and folder `repository` (and use `Repository` suffix) instead of `datasource`. Templates use `repository` for that case. Quick prompts - "Scaffold a `User` model using `json_serializable` and a `UserRepositoryImpl` using `dio` that maps 401 -> invalid credentials." - "Generate DTO tests: `fromJson`, `toJson`, and `toEntity()` round-trip for `UserResponse`." --- > Source: [pedromneto97/custom-skills](https://github.com/pedromneto97/custom-skills) — distributed by [TomeVault](https://tomevault.io).
