The agent-skills repository provides a framework for enhancing AI coding agents with structured engineering workflows called 'skills'. Each skill encodes senior engineer best practices across the software development lifecycle (Define → Plan → Build → Verify → Review → Ship) through opinionated, process-driven guidelines. Skills are invoked automatically based on context or via slash commands and integrate with multiple AI agent tools (Claude Code, Gemini CLI, Antigravity, Codex, etc.) through tool-specific adapters. The system includes a meta-skill for dynamic skill routing, reusable agent personas for specialized tasks, and validation infrastructure to ensure consistency and prevent drift. It is designed to prevent agents from skipping critical steps by mandating concrete evidence (tests, build output) rather than relying on subjective assessments.

This repository is a Webpack plugin that integrates Google Lighthouse for running performance and quality audits during the build process. After Webpack emits assets, the plugin triggers Lighthouse against a specified URL, collects the report, and optionally saves artifacts like screenshots and traces. The codebase consists of two main parts: a Webpack-specific plugin that taps into the compiler's afterEmit hook, and a reusable Lighthouse runner module that handles Chrome lifecycle management, audit execution, and result processing. The project is explicitly marked as deprecated in the README, advising users to use Lighthouse directly instead.
