The most exhaustive enterprise security repository for AI agents, containing 682 production-ready skills mapped to the MITRE ATT&CK and NIST CSF frameworks. Spans deep cloud security audits (AWS, GCP, Azure), incident response forensics (Volatility 3, EVTX logs, Zeek), Active Directory exploitation analysis (ESC1, BloodHound), and Ethereum smart contract auditing with Slither and Mythril.

A methodical offensive security architecture tailored for bug bounty researchers and authorized penetration testers. Routes targets systematically through 7 distinct domains: Web, API, Mobile (Android/iOS), Cloud, Network, Source Code Review, and AI/LLM Security. Enforces an iterative loop: Scope Validation -> Reconnaissance -> Surface Mapping -> Vulnerability Scanning -> PoC Weaponization -> Clean Markdown Reporting.

The official Google Android team repository providing high-precision agent capabilities for Android 15+. Specializes in Jetpack Compose UI architecture, diagnosing recomposition performance bottlenecks, implementing Android 15 mandatory edge-to-edge system insets, CameraX asynchronous capture pipelines, LiteRT (formerly TensorFlow Lite) on-device AI inference with GPU acceleration, and Media3 Cast streaming.

A comprehensive design intelligence engine engineered to permanently solve the problem of generic, boring AI-generated interfaces. Enforces rich aesthetic diversity across 50+ defined design movements (Glassmorphism, Dark Elegance, Bento Grid, Neumorphism, Minimalist Luxe), validates 8 interactive component states, and enforces WCAG 2.2 AA/AAA accessibility compliance across all color contrast pairings.

An enterprise UI/UX engineering toolkit providing end-to-end design token architecture (Primitive -> Semantic -> Component), bidirectional token synchronization with Figma Variables, automated design review scoring across Nielsen's 10 heuristics, hardcoded token linting with design QA gates, and human-first UX copy frameworks with the What-Why-How error handling formula.

Authored by Matt Pocock, creator of Total TypeScript, this repository establishes high-craft coding practices for AI development. Enforces deep module design (low cognitive load, high surface depth), rigorous test-driven development (Red-Green-Refactor), iterative hypothesis loops for difficult bugs, systematic ADR (Architectural Decision Record) creation, and pre-commit hook automation with Husky and lint-staged.

The primary global directory and standard index for the AI coding agent ecosystem. Documents best practices for authoring standardized SKILL.md packages with YAML frontmatter, cross-platform agent invocation (Antigravity, Claude Code, Cursor, OpenHands), Model Context Protocol (MCP) tool integration, and specialized workflow orchestration.
