A comprehensive guide detailing recommended naming conventions for various Go language elements, including packages, structs, interfaces, constants, functions, and error handling. Use this skill when writing, reviewing, or refactoring Go code to ensure adherence to idiomatic Go style.

This skill acts as a Go ecosystem expert, guiding developers through the process of selecting and vetting production-ready third-party libraries and frameworks for Go projects. It enforces best practices by prioritizing the standard library, ensuring library maturity, and evaluating performance and simplicity to avoid over-engineering. Use this when you need to compare alternatives or choose the optimal dependency for a specific task.

This guide serves as a comprehensive blueprint for architecting and structuring Golang projects. It covers best practices for defining project types (CLI, Service, Library, Monorepo), adhering to 12-Factor App principles, standardizing module naming conventions, and establishing optimal directory layouts (cmd/, internal/, pkg/). Use it when starting a new Go application or refactoring a complex codebase to ensure maintainability and scalability.

A comprehensive, type-safe in-memory caching library for Go, designed for advanced system architecture. It supports nine sophisticated eviction algorithms (like W-TinyLFU, LRU, LFU, ARC) to optimize cache hit rates based on specific access patterns. Key features include TTL management, loader chains for read-through caching (with singleflight deduplication), sharding, and Prometheus metrics. Ideal for high-frequency services needing to reduce database load and latency.

This library provides powerful monadic types, including Option, Result, and Either, for Go. It enhances type safety by replacing manual nil checks with type constraints and transforming verbose error handling into composable pipelines. It is essential for adopting modern functional programming patterns and building robust, resilient Go applications.

Improves Go error handling by treating errors as structured data. This utility adds critical context—such as domain, user IDs, stack traces, and machine-readable error codes—to standard Go errors. This capability is vital for enhancing observability, enabling APM tools (like Sentry or Datadog) and on-call engineers to diagnose complex issues quickly without relying on manual log correlation.

A comprehensive collection of composable handlers and middlewares for Go's standard slog package. This skill enables developers to build robust, multi-stage logging pipelines by implementing critical steps like log sampling (throughput control), attribute formatting (PII stripping), advanced routing, and sinking logs to various professional backends (e.g., Sentry, Loki, Datadog). Ideal for production-grade services requiring high observability.

This skill guides users through advanced security auditing and best practices for Golang development. It acts as a senior security engineer, focusing on defense in depth by analyzing critical areas like injection patterns, cryptography, secrets management, and authorization flaws. It supports full codebase audits (using STRIDE and DREAD scoring) and precise PR vulnerability reviews, ensuring secure and resilient Go applications.

A comprehensive guide for systematically diagnosing and fixing bugs, crashes, deadlocks, and performance issues in Go code. It covers debugging methodology, utilizing tools like Delve and pprof, detecting race conditions, and following the Golden Rules to find the root cause, ensuring robust and reliable Go development practices.

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

Complex Skill CLI wraps multi-line metadata and coordinates lark-cli plus Node.js binaries to expose a predictable helper for complex automation or deployment tasks within CLI-driven workflows.

Command-line wrapper around the Google Workspace Admin SDK that fetches audit logs, activity streams, and usage reports (customer, entity, user) for administrators, with schema inspection helpers to craft --params and --json flags.
