Skill UI

This skill provides a demonstration of interacting with external APIs and services using various command-line tools (CLI). It showcases core automation patterns, including fetching API documentation details and listing messages using specific application CLIs, making it ideal for testing and learning API integration flows.

A human-in-the-loop studio for iteratively tuning AI outputs or reviewing complex media/prose. It allows users to directly manipulate visual parameters (color, typography, layout) or annotate documents in real-time, moving beyond static comparison grids or vague prompts. Perfect for designers and content creators who need hands-on, visual feedback.

A sophisticated automated loop that uses vision or video models to evaluate subjective aesthetic quality (e.g., timing, color grade, layout). Instead of relying on numeric metrics, the system renders multiple parameterized variants into one artifact, asks the AI to rate them, and suggests optimal values, repeating the process until convergence. Ideal for design iteration where human judgment is the primary success criteria.

A powerful command-line tool for recording the macOS screen and capturing system audio simultaneously. Unlike QuickTime or standard `screencapture`, this tool captures raw display and system audio directly via ScreenCaptureKit, eliminating the need for complex virtual audio drivers (like BlackHole) or elevated permissions. It is designed for scripted content creation, automated demos, and complex recording scenarios where system audio is required via the CLI.

This skill guides users through expert offer construction, focusing on improving the foundational value proposition rather than just optimizing copy. Learn to master the Value Equation (Dream Outcome, Likelihood, Time Delay, Effort/Sacrifice) and structure a complete offer using key components like bonus stacking, robust guarantees, urgency creation, and ideal payment models. Ideal for services, coaching, courses, and high-ticket B2B direct response sales.

A comprehensive reference guide detailing modern and idiomatic PHP coding standards. It covers best practices across various topics, including type safety (strict typing, union types), object-oriented programming (constructor promotion, enums, match expressions), efficient array handling, robust error handling (exceptions), and modern string manipulation functions. Ideal for developers looking to upgrade legacy PHP code to modern, clean, and performant standards.

A comprehensive playbook for optimizing the entire lifecycle of pull requests. It guides developers through systematic pre-flight cleanup, critical self-audits, local test verification, and structuring high-signal PR descriptions to ensure code quality and fast maintainer approval.

This comprehensive guide details the idiomatic and efficient way to write Scala code. It covers crucial modern practices, such as utilizing functional transforms over traditional loops, embracing pattern matching, using Option/Either for robust error handling instead of null checks or exceptions, and managing concurrency safely. Essential reading for any Scala developer aiming for high-quality, maintainable, and performant codebases.

An open-source, advanced tool for professional post-production of screen recordings. It automatically speeds up idle segments, applies auto-zoom on click clusters, overlays keystroke chips, and renders smooth synthetic cursors. It specializes in generating high-quality, vertical (9:16) videos optimized for social media and public demos.

A powerful utility that queries multiple free APIs (Pexels, Pixabay, Internet Archive, etc.) in a single query. It retrieves normalized, license-tagged results for real-world, historical, or archival images, videos, and GIFs, making it a peer to local semantic search and generative media tools. Includes specialized scripts for fetching and judging audio.

This comprehensive tool generates complete SEO packages for YouTube videos, podcasts, and short-form content. It includes live-researched titles, descriptions, tags, chapters, and detailed audit fixes, helping boost visibility for both new and underperforming content by targeting specific keywords and user intent.

Generates a comprehensive, structured audit based on WCAG 2.2 guidelines. This tool assesses UI and designs across perceivable, operable, understandable, and robust criteria, covering visual, motor, and cognitive accessibility. It produces a prioritized checklist with pass/fail assessments and specific, actionable remediation suggestions for developers and designers.
