Create Custom Agent

This skill helps you create VS Code custom agent files that define specialized AI personas for development tasks. Custom agents configure which tools are available, provide specialized instructions, and can chain together via handoffs.

When to Use

Creating a new custom agent from scratch

Scaffolding an .agent.md file with proper frontmatter

Setting up agent-to-agent handoffs for multi-step workflows

Configuring tool restrictions for specialized roles (planner, reviewer, etc.)

Creating workspace-shared or user-profile agents

When Not to Use

Creating instruction files (use .instructions.md instead)

Creating reusable prompts (use .prompt.md instead)

Modifying existing agents (edit the file directly)
