Skill UI

A comprehensive guide on implementing Firebase Analytics in Flutter applications. Covers setup, automatic screen view tracking, logging custom and predefined events, setting user properties, and adhering to data privacy best practices for accurate user flow analysis and conversion funnel tracking.

This skill provides a comprehensive framework for measuring Go application performance. It guides users through writing robust benchmarks using `testing.B`, running tests with various flags (`-benchmem`, `-cpuprofile`), interpreting complex profiling data (pprof), statistically comparing results using tools like `benchstat`, and setting up CI regression detection. It is essential for deep performance analysis and making statistically sound optimization decisions.

A comprehensive guide for writing, reviewing, and auditing concurrent Go code. It covers core principles of structured concurrency, including proper resource management for goroutines, safe use of channels, mutexes, and advanced synchronization primitives like errgroup and singleflight. Essential for avoiding common issues like goroutine leaks, race conditions, and context propagation failures.

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 detailing best practices for database interaction in Go. It covers secure query writing using parameterized placeholders, handling transactions, managing connection pooling, dealing with NULLable columns, and choosing between libraries like sqlx and pgx, while strongly advising against using ORMs.

A comprehensive guide for managing the entire lifecycle of Go project dependencies. This skill covers best practices for adding, upgrading, removing, and verifying packages using go.mod and go.sum. It emphasizes critical security measures like vulnerability scanning (govulncheck) and adhering to version control standards, minimizing attack surface, and promoting standard library usage.

This skill provides comprehensive linting and static analysis for Go projects using golangci-lint. It enforces numerous best practices, checks for common errors, manages configurations via `.golangci.yml`, and supports auto-fixing. Use it during the entire development lifecycle, including setting up CI/CD pipelines, running pre-commit checks, or refactoring large, legacy Go codebases to ensure high code quality and maintain security standards.

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.

A robust CLI tool for connecting to Lark/Feishu real-time events. It allows streaming, subscribing, and consuming various events (e.g., IM messages, reactions, meeting updates) as NDJSON output. Ideal for developing Lark bots, building real-time message processors, or implementing long-running streaming webhook handlers, especially in AI agent subprocesses.

Master the art of creating, maintaining, and running robust end-to-end (E2E) tests for Flutter applications using the Patrol framework. This skill covers validating complex user journeys, testing interactions with native system features (like permissions and deep links), capturing UI regressions, and ensuring consistent cross-platform behavior across Android, iOS, and Web. Best practice guidelines for deterministic testing are included.

This CLI alias implements the PUA Loop protocol, designed for running structured, iterative verification cycles. It helps developers set up and manage complex coding tasks that require explicit verification commands and defined stop conditions. It serves as a powerful wrapper for AI coding assistants like Codex/Claude, ensuring robust and traceable development workflows.

Enforces explicit user approval before running any delete command so file removals only proceed after permission is granted.
