Skill UI

`jq` is the standard and powerful CLI tool for querying, filtering, and reshaping JSON data. This skill provides expert-level practical patterns for working with deeply nested structures, handling complex transformations (like flattening, renaming, and grouping), and integrating JSON logic into shell pipelines. Essential for parsing API outputs (AWS, GitHub), log files, and building robust Bash scripts.

A comprehensive tool for discovering, vetting, and evaluating Laravel packages. Users can search for packages based on keywords, filter by health score (e.g., Healthy, Unhealthy), and verify compatibility across different Laravel and PHP versions. It helps developers choose actively maintained, robust packages, ensuring project stability and reducing technical debt.

This tool transforms natural language requirements into high-quality, structured Mermaid diagrams. It supports over 20 diagram types, including Flowcharts, Sequence Diagrams, Class Diagrams, ER Diagrams, and Gantt Charts. The process includes parsing requirements, generating raw Mermaid code, and verifying syntax using industry-standard tools, ensuring accurate and professional visualizations for technical documentation.

Tmux is a powerful terminal multiplexer that enables users to manage multiple sessions, windows, and panes within a single terminal connection. It is essential for maintaining persistent connections on remote servers (surviving SSH disconnects), running long-term background jobs, and automating complex, multi-pane workflows directly from shell scripts, significantly enhancing remote development efficiency.

This skill manages comprehensive software development life cycle operations—including issue triage, PR reviews, version releases, bug fixing, and marketing content generation. It operates using a parallel "agent army" of dynamic agents (10-20 per task), requiring the user to adopt an Engineering Manager (EM) mindset. Key principles involve rigorous citation checking (anti-hallucination) and applying multiple roles (Product Owner, Open Source Contributor, Architect) simultaneously to ensure robust, safe, and user-centric outcomes across all platforms.

This tool runs comprehensive diagnostics on the current context mode environment. It checks the status of critical components, including runtimes, hooks, FTS5, plugin registrations, and versions for npm and the marketplace. Use this skill to quickly identify potential technical issues or configuration inconsistencies, ensuring smooth system operation.

Automates updating the Context Mode plugin: fetches the latest GitHub version, rebuilds and installs it, updates the global npm config, and ensures hooks are set, reporting progress through a checklist; falls back to a CLI upgrade command if ctx_upgrade MCP fails.

Detects when a skill's frontmatter block lacks its closing delimiter so editors can fix the metadata formatting before parsing fails.

Context Engineering Protocol optimizes agent sessions by curating persistent rules, specs, source files, and feedback so outputs stay focused, accurate, and aligned with conventions whenever you start work or the quality drops.

Automates browser workflows with persistent page state, letting you script navigation, form filling, screenshots, scraping, or tests while keeping context across runs.

A comprehensive guide on integrating Firebase Analytics into Flutter applications. Learn how to set up the tracking infrastructure, log predefined and custom events (like add-to-cart), set user properties, and track screen views. Essential for robust user behavior analysis and building conversion funnels.

This comprehensive guide details how to correctly implement and manage Firebase Realtime Database within Flutter applications. It covers critical best practices including data modeling (using flattened JSON trees), utilizing real-time listeners, ensuring offline persistence, performing atomic transactions, and implementing security rules. Ideal for applications requiring extremely low-latency synchronization and constant state monitoring.
