Skill UI

This tool enables deep inspection and validation of web applications by connecting to the browser's DevTools Protocol (MCP). It allows agents to perform tasks like DOM inspection, capturing console logs, monitoring network requests, profiling performance, and taking screenshots in a live environment. Essential for debugging UIs, validating API integrations, and performing end-to-end automated testing.

This utility compresses verbose natural language notes, memories, and documents (like markdown files) into a highly dense format. By eliminating filler words, redundant phrases, and grammatical fluff, it significantly reduces the token count for large inputs. Crucially, it strictly preserves all technical content, including code blocks, inline code, URLs, file paths, and commands, ensuring technical accuracy while boosting AI processing efficiency.

A comprehensive guide and function for discovering, searching, and securely installing modular agent skills from an open ecosystem. It helps users identify specialized capabilities needed for domains like web development, testing, or DevOps, utilizing the `npx skills` CLI. The skill emphasizes best practices, including checking skill reputation and requiring explicit user confirmation before running code.

A comprehensive guide on integrating and calling Firebase Callable Cloud Functions within Flutter applications. Covers setup, passing structured data, robust error handling, performance optimization (timeouts, caching), and local testing using the Firebase Emulator Suite.

A comprehensive guide for integrating and utilizing Firebase Data Connect within Flutter applications. Learn how to set up schemas, write typed GraphQL queries and mutations, handle real-time data streams, implement robust offline capabilities, and apply best practices for security and performance.

This comprehensive guide details best practices for implementing robust state management in Flutter using the ChangeNotifier class and the provider package. It covers defining models, ensuring state immutability, optimizing widget rebuild scopes using Consumer, and efficiently calling methods without listening for changes (listen: false). Mastering these techniques is crucial for building scalable and high-performance Flutter applications.

A comprehensive guide to disciplined version control using Git. It outlines best practices for atomic commits, descriptive message formatting (feat, fix, refactor), adopting trunk-based development, and managing feature branches. Use this whenever making code changes, committing, or coordinating complex work streams to ensure code stability and traceability.

Guides multi-round investigation of any GitHub repository, combining API queries, discovery searches, and deep dives to produce structured markdown reports with summaries, timelines, metrics tables, and Mermaid diagrams for executive-ready briefs.

This skill covers the complete workflow for Go performance analysis. It guides developers on writing robust benchmarks, running tests with statistical rigor, profiling hot paths using pprof, analyzing memory/CPU usage, and detecting performance regressions in CI. Ideal for any scenario requiring deep performance measurement in Go.

A comprehensive guide for advanced Go developers, detailing the internals, optimal usage, and performance pitfalls of core data structures like slices, maps, and arrays. It covers capacity growth mechanics, preallocation strategies using `make` and `slices` package functions, and best practices for choosing between various standard library containers (e.g., `strings.Builder` vs `bytes.Buffer`). Essential for writing highly efficient, memory-safe Go code.

A comprehensive guide for optimizing Golang applications, covering systematic approaches to identifying and resolving bottlenecks. It details best practices for reducing memory allocations, improving CPU efficiency, tuning GC, and managing concurrency. The methodology emphasizes profiling first (using pprof, fgprof) and following an iterative cycle: Benchmark → Diagnose → Improve → Benchmark.

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.
