5. Tackle complex, multi-step tasks. Agent mode reads your codebase, suggests edits across files, runs terminal commands, and responds to compile or test failures — all in a loop until the job is done. Further refine agent mode to fit your team's workflows with VS Code extensions and Model Context Protocol (MCP) servers. Agent Mode
6. When working on complex tasks, you can delegate subtasks to subagents. A subagent is an independent AI agent that performs focused work, such as researching a topic, analyzing code, or reviewing changes, and reports the results back to the main agent. Because each subagent runs in its own context window, it doesn't add noise to your main conversation. VS Code can also run multiple subagents in parallel to speed up multi-part tasks. Subagents

10. Summary • Custom Agents aka subagents are standalone AI agents (often power by LLM) that helps the main Copilot Agent to delegate specialized tasks. • Each subagent is designed for specific role or domain e.g. Test Runner Agent, Solution Architect Agent, Lint Agent, Security Architect Agent, Code Review Agent etc. • Custom agents can maintain their own internal context and chain of thought relevant to their domain. • Skills are discrete atomic capabilities or functions that agent performs on demand. E.g. pdf/word/powerpoint generation • Skills are like verbs (actions) the Copilot can perform, subagents are specialized mini-experts for bigger or domain specific tasks .
