Skill UI

A comprehensive Go implementation of ReactiveX for building declarative, type-safe pipelines for asynchronous data streams. It manages complex event sources, handling automatic backpressure, error propagation, and context integration. Ideal for real-time data processing, WebSockets, and event-driven architectures where manual goroutine and channel wiring is complex.

This skill provides comprehensive composable handlers for Golang structured logging using the samber/slog ecosystem. It enables developers to build robust, multi-stage log pipelines by integrating sampling for throughput control, formatters for PII scrubbing, complex routers, and multiple backend sinks (e.g., Sentry, Loki, Datadog). It is essential for building high-observability Go applications.

This comprehensive skill provides a senior Go security engineer persona, guiding users through rigorous security practices for Golang development and code auditing. It covers threat modeling (STRIDE), vulnerability analysis (DREAD), secure development principles, and specialized modes like Review and Audit to detect issues such as injection, crypto flaws, and authorization weaknesses.

Curated guide providing Go resources, newsletters, communities, blogs, and key developers to follow so you can discover libraries, track releases, and learn the language consistently.

This comprehensive guide deep dives into `stretchr/testify`, the essential tool for writing robust and readable unit tests in Go. It covers the crucial differences between `assert` and `require` for controlled failure handling, implementing sophisticated mocks, and managing test lifecycles using suites. It is perfect for developers aiming to write maintainable, self-documenting, and reliable test code in Go.

Guides Go developers through struct/interface design best practices, covering interface segregation, composition, dependency injection, type assertions, and choosing pointer vs value receivers to keep APIs clear and testable.

A systematic guide for debugging complex issues in Go applications, including crashes, deadlocks, concurrency errors, and performance bottlenecks. This skill teaches the 'Golden Rules' of debugging: reproducing bugs, isolating variables, and finding the true root cause rather than applying symptom fixes. It covers advanced techniques using pprof for profiling, the Delve debugger (dlv), and Go's built-in race detector, providing a structured methodology for professional software development.

Provides a well-structured skill template with metadata for `lark-cli`, helping developers verify formatting and readiness before deployment.

Provides a minimal skill definition that only includes the required fields, showing how to structure SKILL.md for quick testing or deployment of basic examples.

Command-line helper that lists upcoming Google Calendar events across every linked calendar, supporting filters for today, tomorrow, week, custom day ranges, calendar names, and timezone overrides to keep planning aligned with your schedule.

Creates a Google Calendar event through the gws CLI by specifying summary, start/end time, and optional attendees, location, description, or Meet link—ideal for automating calendar scheduling from scripts.

Command-line helper to renew or reactivate Google Workspace Events subscriptions, either by specifying a subscription name or by bulk renewing those expiring within a configurable window, ideal for automating cron-based maintenance.
