A hand-picked collection of the finest of resources for the most awesome of agents, Claude Code, the undisputed champion of coding companions, from the unstoppable team at Anthropic PBC. A delectable showcase of top tier skills, ambidextrous agents, scintillating status lines, top notch developer tooling, and also we have plugins. Suitable for beginners and veterans, with an emphasis on code quality, security, and originality.

The current iteration of the list, such as you see it today, was launched with the express intent to highlight resources that were not on the last iteration, and in particular to make selections from the list of recommendations. However, this is only temporary - resources will continue to be added over the coming weeks, and "legacy" resources will be migrated to the new format. So, if you had been featured on the list before, and you don't see your project now, that's the reason why - "legacy" resources that are still maintained and awesome will be added back in soon - and, in the meantime, they are also preserved (but will not be updated) in the README_ALTERNATIVES directory.

• andrej-karpathy-skills by multica-ai - A drop-in CLAUDE.md distilling four behavioral guidelines for LLM-assisted coding into Claude Code — a low-friction quick win. Karpathy-inspired, derived from Andrej Karpathy's public notes on LLM coding pitfalls and authored by multica-ai.
        

• Claude Code Guide by zebbern - A current single-page reference for Claude Code: install, environment variables, slash commands, MCP, hooks, and subagents, kept in sync with the official changelog.
        

• Claude Code Hooks: Complete Guide by Hidekazu Konishi - A thorough walkthrough of every hook event, when each fires, the two return channels, common anti-patterns, and copy-ready settings.json examples.

• Claude Code: Everything You Need to Know by wesammustafa - A conceptual, mental-models-first primer that explains what Claude Code is and how its agentic loop works, then layers setup, prompt-engineering workflows, skills, hooks, MCP, subagents, and agent teams, with an experience-tiered path for newcomers.
        

• claude-howto by luongnv89 - A structured, chapter-based getting-started guide for Claude Code with a self-assessment quiz and a ten-module progressive learning path — slash commands, memory, skills, subagents, MCP, hooks, plugins, and checkpoints — with visual diagrams and copy-paste templates.
        

• explore-claude-code by Luke Renton - An interactive click-through of an annotated Claude Code project where every file and folder — CLAUDE.md, settings.json, rules, commands, skills, agents, hooks, plugins, and .mcp.json — is a real, explained concept, teaching the tool's surface area by orientation rather than prose.
        

• Learn Claude Code by shareAI-lab - A really interesting analysis of how coding agents like Claude Code are designed. It attempts to break an agent down into its fundamental parts and reconstruct it with minimal code. Great learning resource. Final product is a rudimentary agent with skills, sub-agents, and a todo-list in roughly a few hundred lines of Python.
        

• Writing a Good CLAUDE.md by HumanLayer - An essay on CLAUDE.md craft: instruction-budget reasoning, progressive disclosure, and the test of whether Claude would err without a given line.

• Agent Skills by Anthropic - Anthropic's official repository for Agent Skills — the SKILL.md format, a skill template, and example skills, the same format Claude Code loads natively.
        

• Building Effective Agents by Anthropic - Anthropic's foundational taxonomy of agent patterns — prompt chaining, routing, orchestrator-workers, and evaluator-optimizer — and when to use each.

• Claude Code Best Practices by Anthropic - Anthropic's canonical guide to working effectively with Claude Code: the agentic-loop mental model, CLAUDE.md guidance, and workflow patterns.

• Claude Code Cheatsheet by Anthropic - Anthropic's official Claude Code cheatsheet — a quick reference for the core vocabulary (session, context window, CLAUDE.md), built-in slash commands, and keyboard shortcuts.

• Claude Code GitHub Action by Anthropic - The official GitHub Action for running Claude Code in CI: mention @claude in issues and pull requests to delegate code changes, reviews, and fixes.
        

• Claude Code Security Review by Anthropic - An official AI-powered security-review GitHub Action that uses Claude to analyze pull-request diffs for vulnerabilities.
        

• Effective Context Engineering for AI Agents by Anthropic - Anthropic's guide to curating the context window — compaction, just-in-time retrieval, and note-taking — the discipline underlying effective long-horizon agent use.

• How Claude Code Works by Anthropic - The official conceptual explainer of Claude Code's agentic loop, tools, and context window, and how skills, hooks, and subagents layer on top.

• How We Built Our Multi-Agent Research System by Anthropic - A practical account of orchestrator and subagent coordination, prompt design, and evaluation that maps directly to Claude Code's subagents and agent teams.

• Official Plugin Directory by Anthropic - Anthropic's official, curated directory of high-quality Claude Code plugins, installable from within Claude Code.
        

• Steering Claude Code: Skills, Hooks, Rules, Subagents and More by Anthropic - A framework for choosing which extension mechanism to reach for, organized around deterministic-versus-probabilistic control and context isolation.

• Agentic Workflow Patterns by ThibautMelen - A comprehensive and well-documented collection of agentic patterns from Anthropic docs, with colorful Mermaid diagrams and code examples for each pattern. Covers Subagent Orchestration, Progressive Skills, Parallel Tool Calling, Master-Clone Architecture, Wizard Workflows, and more. Also compatible with other providers.
        

• Bloom by Li-Evan - A self-contained Claude Code skill that turns Benjamin Bloom's "2-sigma" tutoring research into a personal AI tutor: it generates a structured syllabus, teaches one lesson at a time, and adapts each next lesson to the learner's annotations and feedback. The skill is dependency-free and makes no network calls beyond the configured LLM endpoint (an optional web app is also included).
        

• cc-thinking-skills by tjboudreaux - A collection of installable thinking-framework skills with a meta-router, notable for publishing a replication-gated evaluation instead of unsupported quality claims.
        

• Claude Code Handbook by nikiforovall - Collection of best practices, tips, and techniques for Claude Code development workflows, enhanced with distributable plugins

• Claude Code Repos Index by Daniel Rosehill - This is either the work of a prolific genius, or a very clever bot (or both), although it hardly matters because the quality is so good - an index of 75+ Claude Code repositories published by the author - and I'm not talking about slop. CMS, system design, deep research, IoT, agentic workflows, server management, personal health... If you spot the lie, let me know, otherwise please check these out.
        

• Claude Code System Prompts by Piebald AI - All parts of Claude Code's system prompt, including builtin tool descriptions, sub agent prompts (Plan/Explore/Task), utility prompts (CLAUDE.md, compact, Bash cmd, security review, agent creation, etc.). Updated for each Claude Code version.
        

• claude-code-android by ferrumclaudepilgrim - A thorough, device-tested guide and toolkit for running Claude Code natively on Android via three paths (Termux, proot-Ubuntu, and the Android Virtualization Framework), with a verification harness and per-device results. Unusually security-aware for a setup guide — it ships a threat model, an SSRF-guard WebFetch hook, a biometric approval gate, and a permission matrix.
        

• claude-code-docs by Constantin Shafranski - A mirror of the Anthropic© PBC documentation site for Claude/Code, but with bonus features like full-text search and query-time updates - up-to-the-minute, fully-indexed information so that Claude Code can read about itself.
        

• cxpak by Barnett Studios - A code-intelligence Claude Code plugin and MCP server (Rust, single binary, 43 languages) that builds a typed dependency graph and packs token-budgeted, annotated context bundles for any task. Exceptionally engineered and security-forward — 2,400+ tests, recorded ADRs, a sandboxed WASM plugin SDK, and cosign-signed, SBOM-attested release images.
        

• Dive into Claude Code by VILA-Lab - A research-lab systematic analysis of the Claude Code codebase whose headline finding — overwhelmingly infrastructure rather than model — reframes Claude Code as a harness.
        

• Encyclopedia of Agentic Coding Patterns by Wolf McNally - A freely available reference covering 190+ patterns for AI-assisted software development (and actually a whole bunch of related technical topics) from foundational concepts through agentic construction patterns, governance, testing, and socio-technical systems. Each entry follows a consistent pattern-language format with Context, Problem, Forces, Solution, Consequences, and Related Patterns. Opinionated and erudiate, which is actually good for an "encyclopedia" in some ways.

• learn-faster-kit by Hugo Lau - A creative educational framework for Claude Code, inspired by the "FASTER" approach to self-teaching. Ships with a variety of agents, slash commands, and tools that enable Claude Code to help you progress at your own pace, employing well-established pedagogical techniques like active learning and spaced repetition.
