Docs, Learning & Lists tools for Claude / Anthropic

World's largest open-source prompt library. 1000s of prompts for all major models

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

Curated resources, tools, and workflows specifically for Claude Code users

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

A book-length architectural teardown of Claude Code's harness: 15 chapters and 139 diagrams covering the tool system, four-stage permission pipeline, context compaction, memory, hooks, subagent scheduling, MCP integration, skills, streaming architecture, and plan mode. Every chapter explains *why* each design decision was made rather than how to call it, distilling transferable mental models for a

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

Two open-source books that use Claude Code and Codex as observation targets to explain how constraint structures organize execution in real engineering environments. The clearest book-length treatment of why prompts, tools, permissions, recovery paths, and team rules form a single control plane rather than accessories around the model

Ryan Lopopolo's anthology, field guide, and agent context bundle for harness engineering: it reframes the harness as the environment that carries an organization's nonfunctional requirements, with reusable AGENTS.md/CLAUDE.md artifacts, playbooks, evals, and domain modeling docs. The most systematic open-source synthesis of how to make organizational judgment cumulative across agent-maintained rep

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

Self-learning system for Claude Code that captures corrections and syncs approved learnings to CLAUDE.md files

Catalog of 80+ terminal-native AI coding agents (open-source and proprietary) plus the harnesses that orchestrate, sandbox, and extend them: session managers, parallel runners, autonomous loop infrastructure, and credential vaults. The most comprehensive reference for the CLI agent layer that most harness infrastructure is designed to host

Trilingual, section-by-section architecture notes on modern agent harnesses: loop engineering, tools, permissions, context, memory, multi-agent coordination, and evaluation, studied through real systems such as Claude Code and Hermes Agent, with runnable Python demos

DESIGN.md files grouped by aesthetic family (editorial, terminal, warm, data-dense, cinematic, playful, glass, brutalist, indie) + remix recipes + prompt packs for Claude Design (Anthropic Labs)

Curated list of AutoResearch use cases with verifiable traces and progress charts, organized by domain (LLM training, GPU kernels, voice agents, trading, etc.)

by Karan Bansal - A community list of Claude Code mods built with function hooks. Scans public GitHub repositories and shows what the validator reports each mod can read, write, run or send over the network

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 p

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

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

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

(307 ⭐) - Scale your compute with Claude Code as a programmable agentic coding tool

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

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)

by Iury Krieger - A Claude Code plugin that turns an Obsidian vault into a structured second brain via 8 skills, building an entity-typed (actors/people/teams/topics…) Zettelkasten graph with bidirectional wikilinks and ingesting Confluence, Google Docs, GitHub, and docling-supported files. Operates only on local markdown, with conscientious, opt-out error reporting that explicitly never transmits

(85 ⭐) - A collection of best practices and procedures for using Claude Code

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

by ngmeyer - A standalone MCP server that gives Claude a markdown second-brain over any Obsidian vault or folder of .md files, with trigram search, auto-wikilinks on write, and real graph analytics (Louvain communities, PageRank, shortest-path, D3 visualization). Runs entirely locally with no network calls or telemetry, productionizing the "LLM wiki" pattern

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

by Taka Goto - A multi-agent Claude Code learning environment for mastering Retrieval-Augmented Generation, with 20 specialist agents, 22 slash commands, and a 9-module hands-on curriculum that runs zero-config inside Claude Code.

Documentation-discovery telemetry for Claude Code — heat/cold maps, health grade, evidence-backed router fixes. 100% local, zero tokens. /tt

by oubakiou - A Claude Code skill plus single-file HTML tool that closes the human-review loop on AI-written docs: a person leaves inline comments in the browser, which export as structured JSON keyed by heading path and line, and the skill polls for that file and applies each comment to the exact lines. Strongly privacy-respecting — the local/CLI build enforces a strict CSP (connect-src 'none'),

by HeyRenan - A Claude Code plugin that turns CSS selectors + text into finished visual documentation — annotated screenshots, flow GIFs/MP4s, terminal recordings, and before/after composites — placing every annotation deterministically and pixel-verifying each artifact (PASS/FAIL) before it is saved. Self-contained (bundles its own headless Chromium, no browser MCP, no telemetry); every image in
