If you could secure your open source GitHub repo in less than 60 seconds, would you do it? Even the best open source repos face the following risks: 🚨 Malware pushed to your branches 📣 Unfixed vulnerabilities disclosed to the public 🔓 Leaked credentials 📦 Vulnerable dependencies 🐛 Security bugs in your code We recently wrote a guidance about the 6 security settings every GitHub maintainer should enable to mitigate those risks: https://lnkd.in/ec6DJQCJ That was so early 2026! Now you can get it done with one command. 🚀 Introducing gh secure One command. Free.

When the cost of error is high, trust is everything. Dan, a director of Senior Corporate Counsel at GitHub, used GitHub Copilot CLI to build a custom skill that embeds inline screenshots of source documents to verify AI analysis. Dan's tool, aptly named Eyeball, helps the legal team check complex clauses and act on AI outputs with confidence. Now, every lawyer at GitHub is using the terminal to streamline their daily workflows. ▶️ More ways the GitHub legal team uses Copilot CLI 👇 https://lnkd.in/e3_5Ph6B

Want to build agentic applications without implementing the agent loop yourself? 💡 Join our beginner-friendly livestream series to explore the GitHub Copilot SDK and learn how to embed Copilot’s agent runtime into your own application or service. You’ll learn how to: • Create multi-turn conversations • Stream responses in real time • Expose application functions as tools • Connect external capabilities through MCP servers • Control agent behavior with hooks and permission handlers • Work with clients, sessions, prompts, and session state We’ll also clarify when to use the Copilot SDK versus the interactive Copilot CLI: use the CLI for developer tasks in the terminal, and the SDK when you want to bring Copilot’s agentic capabilities into your own software. No prior GitHub Copilot SDK experience is required. Plus, special sessions are available for .NET and Java developers.
