| description | Master multi-agent orchestration using Claude Code's agent teams and task system. Use when coordinating multiple agents, running parallel code reviews, creating pipeline workflows with dependencies, building self-organizing task queues, or any task benefiting from divide-and-conquer patterns. Routes to specialized sub-skills for team management, tasks, messaging, patterns, backends, and error handling. |

Claude Code Swarm Orchestration
Master multi-agent orchestration using Claude Code's agent teams and task system.
Experimental: Agent teams are disabled by default. Enable with CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS in your settings.json or environment.
Primitives
| 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 |
| Mode | Permission mode for spawned agents. Set mode: "plan" to require plan approval before the agent acts. See Plan Approval pattern. | Task parameter |
| Isolation | Set isolation: "worktree" to give an agent an isolated git worktree copy. Cleaned up if no changes; returns worktree path/branch if changes are made. Recommended for agents making code changes. | Task parameter |

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: "..." })
Task({ subagent_type: "general-purpose", description: "Apply patch", prompt: "...", isolation: "worktree" })
Message Teammate
SendMessage({ to: "worker-1", message: "...", 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"] })
Spawn with Plan Approval
Task({ team_name: "my-team", name: "planner", subagent_type: "general-purpose", prompt: "...", mode: "plan", run_in_background: true })
Shutdown Team
SendMessage({ to: "worker-1", message: { type: "shutdown_request", reason: "All done" } })
TeamDelete()
Skill Frontmatter Reference
Every skill's SKILL.md starts with YAML frontmatter. name and description are required; all other fields are optional.
| Field | Type | Description |
|---|
name | string | Required. Identifier used to invoke the skill |
description | string | Required. Shown in autocomplete and used by Claude to select the skill |
argument-hint | string | Hint shown during autocomplete (e.g. "[file path or query]") |
user-invocable | boolean | When false, hides from the / menu; skill is background knowledge for Claude only (default: true) |
disable-model-invocation | boolean | When true, Claude won't auto-load this skill; user must invoke via / menu |
allowed-tools | string | Restrict tool access when skill is active (e.g. "Read, Grep, Glob") |
model | string | Model override when skill is active (e.g. "haiku", "sonnet") |
context | string | Set to "fork" to run skill in an isolated subagent context |
agent | string | Subagent type to use when context: fork (e.g. "Explore", "general-purpose") |
hooks | object | Lifecycle hooks scoped to this skill |
String Substitutions
Use these placeholders in your skill content to inject runtime values:
| Substitution | Value |
|---|
$ARGUMENTS | Full user input passed to the skill |
$ARGUMENTS[N] / $N | Nth space-separated argument (1-indexed) |
${CLAUDE_SESSION_ID} | Current Claude session ID |
${CLAUDE_SKILL_DIR} | Absolute path to the directory containing this skill's SKILL.md |
Security: Do not interpolate $ARGUMENTS into !`command` expressions — treat it as untrusted user input. Use $ARGUMENTS in skill body text only, never in shell command substitutions.
Dynamic Context Injection
Add a context field in frontmatter with the bang-backtick syntax to execute a shell command and inject its output when the skill loads. For example, setting context to bang-backtick cat ${CLAUDE_SKILL_DIR}/extra-context.md backtick will read that file into context at load time.
Security: Commands execute locally when the skill loads. Use only safe, read-only commands (e.g., cat, git log, date). Avoid network calls or mutations. Review bang-backtick expressions in third-party plugins before loading.
Note: Do not put the bang-backtick syntax inside code blocks in skill content — the skill loader will attempt to execute it even within fenced code blocks.
Example: Isolated Subagent Skill
---
name: my-explorer
description: Explore codebase for patterns
user-invocable: true
argument-hint: "[pattern or question]"
context: fork
agent: Explore
---
When context: fork is set, Claude spawns a fresh subagent of type agent to handle the skill invocation, keeping the main context clean.
The agent: type determines the tool access scope of the forked subagent:
Explore — read-only (no Edit, Write, or Bash)
Plan — read-only, thoughtful analysis
Bash — shell commands only
general-purpose — full tool access (*)
Choose the most restrictive agent type that meets the skill's needs.
