.agent.md files. These agents possess full workspace awareness and can be augmented with Agent Skills—reusable instruction sets for specific tasks. A new find_symbol tool also grants agents language-aware navigation for languages like C# and TypeScript.This update shifts Copilot from a reactive assistant to a governed agentic framework. By supporting MCP server allowlists, enterprise admins can control which external data sources an agent can access. This solves a security bottleneck, so organizations can safely deploy autonomous agents that interact with sensitive corporate knowledge.
You can now profile tests from the Test Explorer using a dedicated Profiling Agent that analyzes CPU and memory data. During debugging, Copilot provides Smart Watch expression suggestions and inline performance optimizations via PerfTips. These features are in the March 2026 update, including one-click NuGet vulnerability remediation.
GitHub Copilot in Visual Studio now supports custom agents and reusable agent skills to enhance automation and code understanding. • Admins can enforce MCP server allowlists for better security and compliance. https://t.co/6M5ceg5690
