The original title is: "Claude Code multi-agent patterns: sync, async, fork, teammates, and remote agents"

Short summary

A comprehensive guide to Claude Code's multi-agent system, which orchestrates parallel AI agents across isolated git worktrees through a single AgentTool abstraction. It covers five agent types: sync subagents (blocking), async agents (background), fork subagents (context-inheriting), teammates (inter-agent messaging), and remote agents (separate environments). The guide explains when to use each pattern and how parallel execution can reduce wall-clock time significantly for independent tasks.

• •Claude Code's AgentTool supports five agent types: sync, async, fork, teammates, and remote
• •Sync subagents block the parent; async agents enable parallel work across isolated git worktrees
• •Choosing the right pattern prevents blocking, duplicate work, and merge conflicts in multi-agent coding
