GitHub Trending — 2026-07-03
TL;DR
AI-agent tooling dominates today's list — pentesting agents, token-compression tricks for Claude Code, MCP integrations, and cross-tool bridges (Codex-from-Claude-Code) all feature prominently. Python and TypeScript are the most common languages, and long-standing infrastructure projects (Elasticsearch, Ansible, actions/checkout) sit alongside brand-new agent-ecosystem repos.
Top 10
1. usestrix/strix (+2,804 stars today)
An open-source AI penetration testing tool that automatically finds and helps fix vulnerabilities in your app — part of the growing wave of AI agents applied to offensive security.
2. openai/codex-plugin-cc (+629 stars today)
A plugin that lets you invoke OpenAI's Codex from inside Claude Code, so you can have Codex review code or take on delegated tasks without leaving your Claude Code workflow.
3. JuliusBrussee/caveman (+2,851 stars today)
A Claude Code skill that rewrites prompts in terse "caveman speak" to cut token usage by roughly 65%, part of the broader trend toward token-efficient agent prompting.
4. elastic/elasticsearch (+77 stars today)
The well-established free and open-source distributed RESTful search engine, still picking up steady daily interest.
5. actions/checkout (+129 stars today)
GitHub's official Action for checking out a repository in CI workflows — a foundational building block for nearly every GitHub Actions pipeline.
6. ChromeDevTools/chrome-devtools-mcp (+404 stars today)
Exposes Chrome DevTools capabilities via MCP, letting coding agents drive and inspect a real browser — useful for automated web testing and debugging by AI agents.
7. ansible/ansible (+50 stars today)
The widely used, radically simple IT automation platform for deploying and configuring applications and systems.
8. facebook/astryx (+943 stars today)
An open-source, fully customizable design system built to be "agent ready," suggesting design systems are increasingly being adapted for AI-driven UI generation.
9. rommapp/romm (+236 stars today)
A beautiful, self-hosted ROM manager and player for organizing and playing retro game collections.
10. harvard-edge/cs249r_book (+792 stars today)
An open textbook on Machine Learning Systems from Harvard, covering the engineering side of building and deploying ML systems.
