Skill UI

This utility burns an SRT subtitle track directly into an MP4 video file using ffmpeg's libass filter. It re-encodes the video (H.264) while copying the audio untouched. It supports defining custom font fallback chains (e.g., CJK fonts) and provides detailed control over font size, margins, and video encoding parameters (CRF, preset) for professional subtitling workflows.

A utility to generate a static, centered title or end card PNG image. It accepts a main headline, an optional subtitle, background color, and dimensions. It utilizes Pillow, ensuring deterministic rendering suitable for video intros and outros. Supports CJK character wrapping and provides robust font fallbacks, making it reliable for media production pipelines.

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.

A comprehensive design guide for creating ultra-compact, high-utility user interfaces. Ideal for professional tools, financial dashboards, or IDEs where information density is paramount. Principles include compact layouts, monospace typography, high contrast dark themes, and maximizing functional pixels while minimizing whitespace.

This comprehensive skill provides a holistic approach to building modern, accessible, and visually stunning user interfaces. It combines the highly accessible components of shadcn/ui (built on Radix UI), the utility-first power of Tailwind CSS, and sophisticated visual design principles (Canvas). Use this when developing complex React applications, implementing full design systems, ensuring responsive layouts across devices, and requiring professional-grade visual compositions, from dashboards to marketing posters. It guarantees consistency, accessibility, and rapid prototyping.

A comprehensive utility for building reusable, command-line scripts and utilities to interact with the Hugging Face API. It enables complex data workflows by allowing users to chain, pipe, and process data fetched from models, datasets, and various endpoints. Ideal for automation, enrichment, and advanced data pipelines.

This utility detects and redacts sensitive personally identifiable information (PII) from screenshots and images. It can mask various data types, including IDs, credit card numbers, API keys, phone numbers, and emails. Crucially, all processing is conducted locally and offline, ensuring that sensitive data never leaves the user's machine. It is essential for secure debugging, data sharing, and analysis workflows.

rclone is a powerful, feature-rich command-line utility designed to manage files across diverse cloud storage backends, including S3-compatible services. It provides robust, reliable equivalents to core Unix commands (sync, copy, move, mount). Use this skill for all terminal-based cloud operations, such as syncing, backing up, downloading, or managing remote data securely.

A comprehensive utility for managing complex cmux topologies, including workspaces, panes, and surfaces. This tool is essential for inspecting, controlling, and monitoring multiple AI coding agents running in parallel within a macOS terminal environment. It supports advanced functionalities such as browser automation and real-time status notifications, optimizing developer workflows.

This utility converts a single, high-level objective into a comprehensive, step-by-step build plan suitable for complex, multi-agent, or multi-session engineering projects. It automatically handles dependency mapping, detects parallel steps, and structures each step with self-contained context briefs, ensuring any new agent can execute it without prior knowledge. Ideal for large-scale refactoring or feature development spanning multiple PRs.

This utility formats prompts for multiple Large Language Model providers (including Anthropic, OpenAI, Gemini, and Ollama) using standardized chat templates. Furthermore, it enables the creation and utilization of an HNSW index for advanced context retrieval, making it ideal for building robust Retrieval-Augmented Generation (RAG) pipelines.

This utility provides garbage collection for Claude Code configurations. It periodically scans various directories—including skills, memory files, hooks, permissions, and caches—to identify orphaned, stale, or redundant configuration items. Crucially, the process is designed to be non-destructive, always requiring explicit human confirmation for every deletion to ensure a safe, audited cleanup process.
