Skill UI

Guides idiomatic Rust ownership, error handling, traits, and concurrency patterns so teams can build safe, maintainable, and performant applications while reviewing or refactoring existing crates.

Provides step-by-step guidance for activating and using the Example Skill, covering triggers, prerequisites, instructions, expected output, and error handling.

This skill focuses on building new API connectors or providers for an existing repository by strictly adhering to the host project's established architectural patterns. It goes beyond basic HTTP calls, requiring alignment with the repository's native standards for connector layout, configuration schemas, authentication models, error handling, and testing frameworks. Use this when integrating a new service while maintaining architectural consistency with the current codebase.

This skill guides developers on integrating Firebase AI (Gemini) into Flutter applications. It covers essential topics including initial setup and configuration, generating text and managing multi-turn chat responses, implementing real-time streaming output, handling multimodal prompts (text and images), and ensuring robust error handling, security, and adherence to data privacy best practices.

This comprehensive skill guide details how to correctly integrate and manage Firebase Authentication within Flutter applications. It covers initial setup, real-time state observation using streams, and implementing various sign-in methods, including email/password, phone, and major social providers (Google, Apple). It also emphasizes secure coding practices, error handling, and state management best practices.

This skill provides a comprehensive guide on securely integrating and calling Firebase Cloud Functions from Flutter applications. It covers the proper use of `httpsCallable` to invoke structured server-side logic, handling data serialization, implementing robust error handling (including permission denial and timeouts), configuring regional deployments, and utilizing the Firebase Emulator Suite for reliable local testing.

Guides integrating Firebase Cloud Storage with Flutter apps, covering setup, uploads/downloads, metadata, error handling, and security best practices for file management workflows.

Practical guide for Go developers to write safe, observable database code with policy on parameterized queries, context propagation, error handling, transactions, isolation, connection pools, batching, and migration tooling for Postgres/MariaDB/MySQL/SQLite.

Provides comprehensive guidelines for writing robust and idiomatic error handling in Go applications. Covers best practices like error wrapping (`%w`), using `errors.Is`/`errors.As`, adhering to the single handling rule (log or return), and implementing structured logging with `slog`. Essential for building maintainable, production-ready Go code.

Guides Go distributed-system engineers through protobuf layout, interceptor design, error handling, TLS/mTLS setup, bufconn testing, and streaming RPC patterns so they can implement, review, and debug real-world gRPC servers and clients with production-grade operability.

Adds samber/oops structured error builders to Go services, giving stack traces, codes, user-friendly messages, panic recovery, and exporter-friendly attributes for observability and diagnostics.

OpenViking Code Repository Search exposes `ov` terminal commands for scoped semantic, keyword, and glob searches across viking:// resources, lets you read directory summaries/files, and manage indexed repositories (add/remove) with documented error handling.
