Top 10 GitHub Repos
- caveman
- A Claude Code skill that rewrites the agent's outgoing prompts in caveman-style English ("why use many token when few token do trick") and reports a measured ~65% token reduction on standard coding workflows. MIT-licensed, JavaScript, 3,441 forks, and pinned at the top of the Claude Code skills marketplace. Created 2026-04-04 and the largest viral hit of the cycle — the meme framing did more for token-efficiency adoption in six weeks than the prior six months of academic prompt-compression work.
- deer-flow
- ByteDance's open-source long-horizon SuperAgent harness — sandboxes, memory, tools, skills, sub-agents, and a message gateway in one harness aimed at multi-minute-to-multi-hour tasks. LangChain / LangGraph-based with a polished Node.js / TypeScript control plane and a TikTok-grade product polish. Still shipping commits daily (819 open issues, 9,112 forks at this snapshot).
- chrome-devtools-mcp
- Google's official Chrome DevTools MCP server — gives coding agents a Puppeteer-backed live browser they can navigate, debug, inspect network traffic in, and run profiler traces against. TypeScript, Apache-2.0, pushed today (2026-05-18) with continuous releases on npm. Already the de facto browser-control MCP for Claude Code and Cursor, replacing the homegrown Playwright shims most teams had been hand-rolling.
- serena
- A semantic-retrieval + code-editing MCP toolkit that exposes IDE-grade language-server operations (symbol lookup, references, refactors) to any MCP client. Works alongside Claude Code, Codex, JetBrains, and Cursor; Python-based, MIT-licensed, 1,632 forks, 104 open issues. Effectively "the IDE for your agent" — replacing grep + read-file scaffolding with proper LSP-aware tool calls.
- Skill_Seekers
- Converts documentation websites, GitHub repositories, and PDFs into Claude AI skills with automatic conflict detection. Python, MIT-licensed, AST-parser-backed, OCR support for PDFs, web-scraping for docs sites, and a hosted companion at skillseekersweb.com. 1,402 forks and 97 open issues — community-driven, with daily pushes.
- TradingAgents-astock
- A multi-agent investment-research framework adapted for Chinese A-share markets — seven analyst agents (fundamentals, sentiment, technical, risk, etc.) running a bull / bear debate over A-share data sources (Dragon-Tiger list, hot-money flow, unlock schedules). A heavy fork-and-refit of the original TradingAgents repo. Created 2026-05-13; 96 forks in five days, with the China-domestic angle driving the velocity.
- hermes-agent-control-room
- A "control room"-first template for operating Hermes agents — one VPS hosts an orchestrator that fan-outs to specialist teams and orchestrated workflows, with Shell-driven provisioning and a web console. Created 2026-05-15; 54 forks in three days. Targets the Nous Research / Hermes line specifically rather than being yet another LangGraph wrapper.
- elephant-agent
- A personal-model-first self-evolving AI agent. The headline pitch: the agent runs against your own local / fine-tuned model and rewrites its own context graph as it goes. Python, 23 open issues already (meaning real users on day three), and explicitly positioned against the "everyone runs Claude" default. Created 2026-05-15.
- agent-study
- A 36-chapter agent-engineering curriculum (Chinese) — runnable Python files for ReAct loops, Claude Code reverse-engineering, MCP and A2A protocols, RAG, DSPy, and production observability — explicitly framed as interview prep. Created 2026-05-14 and at 264 stars / 20 forks four days later, with the interview-prep angle pushing it past the saturated "learn LangChain" cohort.
- token-tracker
- A token-usage and cost dashboard for local AI agents — custom Claude Code StatusLine, CLI dashboard with cost analysis, rate-limit monitoring, and session tracking. Python with the rich terminal UI, 23 forks, MIT-style permissive. Created 2026-05-08. Sits next to caveman as the second half of the "what are my agents actually costing me?" answer — caveman cuts tokens, token-tracker shows the bill.
