Skill UI

A comprehensive guide for integrating Firebase Crashlytics into Flutter applications. It teaches how to capture fatal, non-fatal, and isolate errors, customize reports with user identifiers, custom keys, and logs, and manage opt-in data collection to ensure robust crash monitoring in production environments.

Guides building production-ready user interfaces with thoughtful component architecture, consistent spacing, typography, color, and accessibility standards while avoiding generic AI aesthetics and over-configured patterns.

A comprehensive guide for setting up production-grade CI/CD pipelines for Go projects using GitHub Actions. This skill covers essential quality gates including unit testing, linting (golangci-lint), static analysis security testing (SAST), vulnerability scanning, dependency management, Docker builds, and automated releases using GoReleaser.

A comprehensive guide to creating production-ready, idiomatic Go applications. Covers critical patterns such as functional options, robust error handling, graceful shutdown, resource management, and architectural best practices. Ideal for refactoring existing Go code, choosing between architectural patterns, or designing scalable APIs and constructors.

A comprehensive guide to implementing robust, idiomatic error handling in Go. It covers best practices for error creation, context wrapping using `%w`, type-safe inspection with `errors.Is`/`errors.As`, adhering to the single handling rule, and utilizing structured logging with `slog`. Essential for building scalable, debuggable, and production-ready Go applications.

A comprehensive guide for building, reviewing, and debugging production-grade gRPC microservices using Golang. Covers critical patterns such as setting up interceptors for cross-cutting concerns (logging, auth), robust error handling with specific status codes, managing client deadlines, and implementing graceful service shutdowns.

This skill acts as a Go ecosystem expert, providing recommendations for production-ready libraries and frameworks. It guides developers through selecting the simplest, most performant, and idiomatic Go solution, prioritizing the standard library first and only suggesting external dependencies when they provide clear, necessary value.

A comprehensive guide for deploying, configuring, and maintaining the OpenViking server in production environments. It covers service configuration management, environment setup using `uv` for virtual environments, reliable startup procedures using `nohup`, graceful shutdown methods, and critical data cleanup workflows. This resource is essential for DevOps engineers and system administrators managing OpenViking services.

Guides teams through a final launch-readiness checklist covering code quality, security, performance, documentation, feature flags, staged rollouts, and monitoring to ensure confident production deployments.

Comprehensive Go testing guidance that spans table-driven subtests, testify suites, mocking, unit/integration tests, benchmarks, coverage, fuzzing, goleak leak detection, snapshot checks, and GitHub Actions CI to keep production suites reliable.

This skill provides robust mechanisms to verify the integrity of AI agent plugins, tools, and dependencies. It generates deterministic SHA-256 manifests (INTEGRITY.json) for all components, allowing users to detect unauthorized modifications, track provenance, and ensure that deployed assets match their published versions. Use this during CI/CD pipelines, code review, and pre-production promotion to secure the entire agent ecosystem.

A comprehensive guide for resolving complex timezone issues in .NET and C# applications. It provides production-safe patterns for handling location lookups, converting between Windows and IANA timezone IDs, managing Daylight Saving Time (DST), and ensuring cross-platform compatibility. Includes ready-to-use code snippets for TimeZoneInfo, NodaTime, and DateTimeOffset.
