Agents Overview

Copilot Collections provides 12 specialized agents (plus 3 internal sub-agents) that together form an AI product engineering team covering the full delivery lifecycle — from product ideation through development, infrastructure, and quality assurance. Agents are stored in .github/agents/ as .agent.md files. VS Code loads these automatically when the corresponding mode is selected.

How Agents Work

Each agent has:

• A defined role — What the agent specializes in and what it should/shouldn't do.
• Tool access — Which MCP integrations and VS Code tools it can use.
• Skill bindings — Which skills it loads for domain-specific knowledge.
• Handoffs — Buttons to seamlessly transition between workflow phases.
