GitHub's trending list is a study in one theme: AI agents. The repos gaining the most stars today are almost all tooling for the agent era — skills libraries, context optimization, memory systems, and harnesses for orchestrating coding agents — with a couple of reverse-engineering and audio staples rounding out the list.
- morluto/rea (TypeScript) — 32 282 stars today. Reverse-engineers everything with agents, from app behavior down to native binaries.
- K-Dense-AI/scientific-agent-skills (Python) — 1 091 stars today. Turns an AI agent into an "AI scientist" with 177 validated skills for biology, chemistry, medicine, and drug development.
- debpalash/VoiceStudio (Python) — 3 027 stars today. Open-source, fully local alternative to ElevenLabs: voice cloning, dubbing, transcription, and audiobooks in 646 languages.
- NationalSecurityAgency/ghidra (Java) — 1 366 stars today. The NSA's software reverse-engineering framework.
- affaan-m/ECC (JavaScript) — 1 015 stars today. Performance optimization for agent harnesses: skills, memory, security, and research-first development for Claude Code, Codex, Cursor, and more.
- mksglu/context-mode (TypeScript) — 902 stars today. Optimizes the context window for AI coding agents: cuts tool output by up to 98%.
- obra/superpowers (Shell) — 688 stars today. An agent skills framework combined with a development methodology.
- JuliusBrussee/caveman (Go) — 530 stars today. Viral skill + proxy for coding agents that cuts token usage by 65%.
- anthropics/claude-plugins-official (Python) — 525 stars today. Anthropic's official catalog of high-quality Claude Code plugins.
- ruvnet/ruflo (TypeScript) — 224 stars today. "The original agent harness": agent swarms, autonomous workflows, adaptive memory, and RAG integration.
Bottom line: Eight of the ten repos are directly about AI agents and their development workflows. It's clear that agent tooling is the hottest area on GitHub right now.
