Stop overloading your skills

You built a skill for your technology. API references, authentication flows, SDK patterns, error handling, version info, all packed into one skill. The agent calls it, gets all that context, and generates code. The kicker? You've just wasted a lot of tokens. It already knows Models have...

Streamline C++ Code Intelligence Setup in Copilot CLI

Sinem Akinci
C++ developers can now bring IDE-style semantic intelligence into Copilot CLI with less setup. The C++ language server plugin supports richer code navigation, diagnostics, symbol understanding, and code changes by using the same build context your compiler does. That build context...

Add vs Stage and Register

Howard Kapustein
As previously mentioned to 'install' a package, as people think of the term, Windows actually performs two separate operations: staging and registration. To oversimplify: Staging puts the package content on disk. At this point the package is present, but inert and unused. Registering...

Build your own claw and agent harness with Microsoft Agent Framework

Wes Steyn

Separating Deterministic Extraction from AI Inference in Industrial Summarization

Viktor Ciroski
