Primitive	What It Is	File Location
Agent	A Claude instance that can use tools. You are an agent. Subagents are agents you spawn.	N/A (process)
Team	A named group of agents working together. One leader, multiple teammates.	`~/.claude/teams/{name}/config.json`
Teammate	An agent that joined a team. Has a name, color, inbox. Spawned via Task with `team_name` + `name`.	Listed in team config
Leader	The agent that created the team. Receives teammate messages, approves plans/shutdowns.	First member in config
Task	A work item with subject, description, status, owner, and dependencies.	`~/.claude/tasks/{team}/N.json`
Inbox	JSON file where an agent receives messages from teammates.	`~/.claude/teams/{name}/inboxes/{agent}.json`
Message	A JSON object sent between agents. Can be text or structured (shutdown_request, idle_notification, etc).	Stored in inbox files
Backend	How teammates run. Auto-detected: `in-process` (same Node.js, invisible), `tmux` (separate panes, visible), `iterm2` (split panes in iTerm2). See Spawn Backends.	Auto-detected based on environment

How They Connect

    subgraph TEAM[TEAM]
        Leader[Leader - you]

Quick Reference

Create Team and Spawn Teammate

TeamCreate({ team_name: "my-team", description: "Working on feature X" })
Task({ team_name: "my-team", name: "worker", subagent_type: "general-purpose", prompt: "...", run_in_background: true })

Spawn Subagent (No Team)

Task({ subagent_type: "Explore", description: "Find files", prompt: "..." })

Message Teammate

SendMessage({ type: "message", recipient: "worker-1", content: "...", summary: "Brief update" })

Create Task Pipeline

TaskCreate({ subject: "Step 1", description: "...", activeForm: "Working on step 1..." })
TaskCreate({ subject: "Step 2", description: "...", activeForm: "Working on step 2..." })
TaskUpdate({ taskId: "2", addBlockedBy: ["1"] })

Shutdown Team

SendMessage({ type: "shutdown_request", recipient: "worker-1", content: "All done" })
// Wait for approval...
TeamDelete()
