This repository is a curated collection of skill plugins for AI coding agents such as Claude Code, Codex, and Cursor. Each skill is a self-contained directory with a SKILL.md descriptor, executable scripts, reference documents, and templates. The ecosystem covers a wide range of capabilities: multi-provider media generation (images, video, audio), browser automation via CDP, macOS app telemetry auditing, document format replication, open-source preparation (secret scanning, license generation), Cloudflare Workers deployment, trend aggregation, and video processing. The skills are designed to be invoked by an AI agent reading the SKILL.md and executing workflows via CLI scripts. While primarily an application-oriented collection, some skills (e.g., happy-app-audit) incorporate data analysis and reverse-engineering methodology, giving it a hybrid character. The architecture is modular: each skill is independent, with consistent patterns for provider abstraction, async polling, and template-based output. This makes the repository a practical toolkit for extending agent capabilities rather than a standalone production service.
