About claude-code-ultimate-guide
FlorianBruniaux/claude-code-ultimate-guide
A tremendous feat of documentation, this guide covers Claude Code from beginner to power user, with production-ready templates for Claude Code features, guides on agentic workflows, and a lot of great learning materials, including quizzes and a handy "cheatsheet". Whether it's the "ultimate" guide to Claude Code will be up to the reader :)
Includes a built-in MCP server and threat database tracking 655 malicious skills across 24 CVEs, enabling developers to build secure agentic workflows. Features 41 Mermaid architecture diagrams, methodology guides (TDD/SDD/BDD), and a 271-question knowledge validation quiz designed around decision frameworks rather than config templates. Positions itself as the conceptual complement to production-ready template libraries, targeting teams moving beyond copy-paste patterns to designing custom multi-agent systems.
About claude-skills
alirezarezvani/claude-skills
+180 production-ready skills & plugins for Claude Code, OpenAI Codex, and OpenClaw — engineering, marketing, product, compliance, C-level advisory, and more. Install via /plugin marketplace.
Skills and agents are packaged as modular instruction sets with structured SKILL.md files, 268 stdlib-only Python CLI tools, and conversion scripts that auto-translate to native formats (`.mdc` for Cursor, `CONVENTIONS.md` for Aider, `.kilocode/rules/` for Kilo Code, etc.). The architecture separates skills (task execution), agents (task orchestration), and personas (cross-domain reasoning), all installable via plugin marketplaces or `./scripts/convert.sh --tool all` for multi-tool deployment. Designed to work across Claude Code, OpenAI Codex, Gemini CLI, Cursor, Aider, Windsurf, and seven other AI coding agents without platform-specific refactoring.
