178K stars (up from 159.3K on April 26) — Jesse Vincent's structured development methodology for Claude Code and 13+ other agents. Five composable phases: Brainstorm, Design (interactive HTML mockups), Plan (git-worktree task breakdown), Code (parallel subagents with 6-category self-check), and Verify (security audit). Official Anthropic marketplace plugin since January. v5.0.7 current.
82.7K stars (12K forks). Garry Tan's open-sourced Claude Code setup — 23 specialist skills as slash commands: CEO, Designer, Eng Manager, QA Lead, Security Officer, Release Engineer, and more. Surpassed 10K stars in its first 48 hours. The design-review skill catches AI slop before it ships, making it the most-watched anti-slop harness in the ecosystem right now.
58.4K stars for a Tauri-powered desktop app that unifies Claude Code, Codex, OpenCode, OpenClaw, and Gemini CLI in one GUI — 50+ provider presets, one-click MCP and Skills sync across all agents, and a system-tray switcher. Become the go-to desktop control panel for teams running multiple AI CLI tools side-by-side.

59.6K stars. v1.40.0 shipped May 3 with per-phase model routing, dynamic failure-tier escalation, and a --research-phase flag for the plan command. The --minimal install profile cuts cold-start system-prompt overhead by 94% (from ~12K tokens to ~700), making it the single biggest token win per install in the ecosystem.
52.9K stars. v1.7.0 landed May 1 adding cavecrew (multi-agent cave team), stats receipts, and MCP-shrink — a new MCP input-token compressor that cuts ~46% of input tokens every session on top of the existing 65% output-token reduction. One of the most-installed cost skills in the ecosystem.
55K stars. Multi-model orchestration harness that transforms a single AI coding assistant into 11 parallel specialists (Sisyphus orchestrator on Claude Opus 4.7, sub-agents on Gemini/Kimi/GLM). Ships 52 lifecycle hooks, 26 tools, and a 3-tier MCP system — each task auto-routes to the cheapest capable model, making it the most cost-aware harness after caveman.
21.5K stars, v1.0.32 shipped May 1. AI-powered browser automation that gives Claude Code eyes and hands in any web UI — acts, extracts, validates, handles 2FA, integrates with password managers (Bitwarden, 1Password, LastPass). `skyvern setup claude-code` wires it directly into Claude Code; Anthropic Claude is a first-class supported LLM. Cuts the gap between code-generation and real-world web workflows.
131K GitHub stars in ten weeks — faster than LangChain or AutoGPT. NousResearch's self-improving agent creates skills from experience, searches past conversations, and builds persistent user models across sessions. v0.12.0 shipped April 30. Runs Claude via OpenRouter or direct API; includes a Claude Code SKILL.md in the repo.
173K stars and v2.0.0-rc.1 released in April with desktop dashboard GUI, operator workflows, media tooling, and a Rust-based ECC 2.0 alpha control plane. Bundles 48 agents, 182 skills, 68 command shims, and multi-language rules — the highest-starred Claude Code harness on GitHub.
71.4K stars and v12.3.8 with 244 releases. Hooks into Claude Code's session lifecycle, compresses tool usage into semantic summaries via the Agent SDK, and stores them in a local SQLite+Chroma vector DB — injecting relevant context automatically on next session start. @simonscrapes compared all Claude memory systems this week and claude-mem topped for zero-config simplicity.
25.8K stars. Open-source coding-agent CLI derived from the Claude Code codebase, reengineered for multi-provider use — OpenAI, Gemini, GitHub Models, Ollama, and local servers all work with saved profiles via /provider. Supports bash, file ops, grep, glob, agents, tasks, MCP, slash commands, streaming, vision, and VS Code extension integration. MIT licensed, not affiliated with Anthropic.
42.1K stars for an AI-powered job search system built entirely on Claude Code: 14 skill modes, a Go terminal dashboard, PDF resume generation, and Playwright-powered batch scanning of 45+ career portals. The creator used it to evaluate 740 job listings and land a Head of Applied AI role — one of the most concrete real-world Claude Code skill systems to ship this year.
41.6K stars. Ultra-lightweight personal AI agent at v0.1.5.post3 (April 29). Keeps the core agent loop small and readable while supporting MCP, multi-platform chat (Telegram, Discord, Slack, WeChat), 24/7 market analysis, and full-stack software engineering tasks. Built as an open alternative to Claude Code's architecture — inspects Claude Code's design philosophy but runs any LLM.

19.1K stars. 131+ specialized Claude Code subagent definitions organized across 10 categories — language specialists, infrastructure, QA, data/AI, DevEx, business/product, meta-orchestration, and research/analysis. Each subagent runs in an isolated context window, carries domain-specific instructions, has granular tool permissions, and includes a model field that auto-routes to the right Claude tier.
