Skill UI

Automates CI/CD pipeline setup, from linting and type checks to integration, E2E, security, and deployment stages, plus feedback loops for AI agents and preview deployments.

This guide provides detailed best practices for writing and maintaining comprehensive End-to-End (E2E) test cases for the 'lark-cli' tool. It covers the entire workflow, from exploring live help documentation and identifying leaf commands, to structuring state-proving tests (e.g., read-after-write assertions) and generating the required `coverage.md` artifact. Use this when adding or significantly updating E2E coverage for any specific functional domain.

Guides structured reviews for Flutter/Dart pull or merge requests, checking correctness, security, style, tests, and documentation while verifying branch scope and CI health.

Guides AI agents through analyzing working code, spotting overly complex structures, then refactoring for clarity while preserving exact behavior and project conventions, especially after reviews or high-pressure edits.

This skill covers the advanced language features introduced in Dart 3, including Pattern Matching, Records, sealed classes, and enhanced control flow structures. Learn how to use `if-case` and switch expressions to write safer, more concise, and idiomatic Dart code, and how to manage complex data shapes using records and patterns.

Analyzes Excel and CSV uploads with DuckDB, inspecting schemas, running SQL, summarizing statistics, and exporting results so users can explore structured data efficiently.

Guides engineering teams through planning and executing deprecation, migration, and removal of legacy systems, ensuring replacements, tooling, and communication keep users safe.

Guides writing documentation and ADRs to capture why architectural or API choices were made, when to comment, and how to structure README/API info so future engineers and agents understand the rationale and trade-offs.

This comprehensive guide details how to correctly implement Firebase App Check for Flutter applications. It covers selecting platform-specific attestation providers (like Android Play Integrity and Apple DeviceCheck), configuring debug tokens, handling token refresh, and setting up enforcement mechanisms. Use this skill to significantly harden your app's security against abuse, ensuring only legitimate clients can access protected backend resources.

This skill provides a comprehensive guide to integrating and managing Firebase Authentication within Flutter applications. It covers critical steps such as initial setup and configuration, implementing state management by listening to authentication streams, and executing various sign-in flows (email/password, phone, and major social providers like Google and Apple). Furthermore, it emphasizes robust error handling and applying security best practices.

This comprehensive guide provides an end-to-end solution for implementing Firebase Cloud Messaging (FCM) in Flutter applications. It covers platform-specific setup for iOS, Android, and Web, detailing how to handle messages in foreground, background, and terminated states. Key topics include managing notification permissions, handling token lifecycles, and implementing reliable cross-platform push notification logic.

A comprehensive guide on utilizing Firebase Remote Config within Flutter applications. Learn how to implement dynamic feature flags, execute A/B testing, manage remote parameter defaults, and fetch real-time configuration values. This skill allows developers to modify app behavior and user experiences without requiring an app store update, ensuring fast iteration and efficient product testing.
