Mastering Subagents in VS Code + Copilot: How To Actually Use Them

Subagents

If you’ve ever dumped a giant problem into Copilot Chat and watched the conversation slowly turn into spaghetti, subagents are the feature you’ve been waiting for. Think of subagents as specialized mini-Copilots you spin up on demand. You hand them a self-contained problem: refactor this mess, write tests for that file, scan the workspace for security issues – and they go off and do the heavy lifting in an isolated context while you keep working. They landed in VS Code v1.107 (December 2025) as part of the GitHub Copilot Chat experience, and they’re one of those things that feels “nice to have” at first… right up until you use them … Read more

Imaginet’s Experience with GitHub CoPilot 

GitHub CoPilot

GitHub CoPilot is a new tool that uses artificial intelligence to help developers write code faster and better. It is powered by OpenAI Codex, a large-scale neural network that has been trained on billions of lines of public code. GitHub CoPilot can generate code snippets, tests, functions, and entire classes based on natural language descriptions or comments.  I have been curious about GitHub CoPilot ever since it was announced in 2021, but I was also skeptical about how well it could handle the complex and dynamic nature of software development. We started testing it around the middle of 2023 and had a mix of developer skill level (jr, int, expert) … Read more
