Turn plain-English product requirements into a reactive, type-safe Convex backend design. Get guidance for schemas, functions, authentication, storage, scheduling, real-time features, and agent workflows.

Les composants Convex ont besoin d’une propriété claire des données, de fonctions wrappers et de types générés. Cette compétence guide la conception, l’implémentation, le câblage et la validation des composants pour les projets Convex.

Subscription billing requires coordinated checkout, webhook, and access-control logic. This skill provides a focused Convex workflow using the maintained Stripe component.

Convex authentication can fail silently when server and client configuration diverge. This skill wires providers, keys, configuration, UI, and verification steps.

Les requêtes Convex peuvent être vastes, et les équipes peuvent choisir le mauvais workflow. Cette compétence oriente Claude, Codex et Claude Code vers des conseils de configuration et des compétences Convex spécialisées.

Les projets Genkit peuvent échouer lorsque les API, les noms de modèles et la configuration des fournisseurs divergent. Cette compétence guide les développeurs Node.js et TypeScript avec une configuration à jour, des exemples et des étapes de dépannage.

Les équipes Java ont souvent besoin de tests ciblés qui respectent le style existant du projet. Cette compétence guide Claude, Codex et Claude Code pour créer des tests JUnit et Mockito avec des mocks pratiques.

Flutter REST integrations require platform permissions, response validation, parsing, and clear UI states. This skill provides a structured implementation workflow using Dart's http package.

Flutter localization setup requires coordinated dependency, generator, resource, and app configuration changes. This skill guides those changes with examples for strings, placeholders, plurals, and selects.

Manual JSON mapping can produce runtime type errors and duplicated parsing logic. This skill guides type-safe models, HTTP parsing, validation, and isolate usage.

Flutter constraint errors can hide the widget that caused the failure. This skill maps common error signatures to focused layout corrections and verification steps.

Rigid Flutter interfaces overflow or stretch across changing window sizes. This skill guides adaptive layouts using constraints, breakpoints, flexible widgets, and large-screen width limits.

Flutter features become difficult to maintain when UI, business logic, and data access are mixed. This skill organizes them into clear, testable layers.

Flutter UI changes can fail when rendering and user interactions are not tested. This skill provides a clear workflow for building focused WidgetTester tests and validating state changes.

Flutter widgets can be difficult to inspect without launching the full application. This skill adds isolated previews with appropriate annotations, configurations, and workflows.

Dart primary constructors introduce new syntax and scoping rules that can make migrations difficult. This skill explains the rules and guides correct refactoring from traditional constructors.

Complex Dart branching can obscure validation, destructuring, and subtype handling. This skill selects clear patterns and checks exhaustive switch behavior.

Native C and C++ integration in Dart requires platform-aware build, link, and packaging hooks. This skill guides local compilation, verified binary downloads, and linker tree-shaking.

Dart diagnostics can be difficult to review and resolve before a commit. This skill guides Claude Code, Claude, and Codex through analysis, reviewed fixes, and formatting.

Dart package conflicts can block builds and make upgrades difficult. This skill provides a controlled workflow to inspect constraints, update dependencies, and verify the resolved graph.
