System	`MessageBus` class	`teammate_mailbox`
Send Direct	`send(message)`	`write` operation
Broadcast	`broadcast(message)`	`broadcast` operation
Queue	`PriorityMessageQueue`	File-based mailbox
Persistence	In-memory + optional persist	`~/.claude/teams/{team}/mailbox/`

SPTFlo V3 (types.ts:237-265):

typescript

export type MessageType =
  | 'task_assign'
  | 'task_complete'
  | 'task_fail'
  | 'heartbeat'
  | 'status_update'

  payload: unknown;
  timestamp: Date;
  priority: 'urgent' | 'high' | 'normal' | 'low';
  requiresAck: boolean;
  ttlMs: number;
}

TeammateTool (from binary):

"write" (42 refs) → Send to specific teammate
"broadcast" (42 refs) → Send to all teammates
"teammate_mailbox" (3 refs) → Message storage

3.2 Message Flow Patterns

SPTFlo V3:

Coordinator → MessageBus.broadcast() → All Agents
Agent → MessageBus.send() → Specific Agent
Agent → MessageBus.subscribe() → Receive messages

TeammateTool:

Coordinator → TeammateTool.broadcast → All Teammates
Teammate → TeammateTool.write → Specific Teammate
Teammate → Mailbox polling → Receive messages

4. Consensus & Plan Approval

4.1 Consensus System

Feature	SPTFlo V3	TeammateTool
Propose	`proposeConsensus(value)`	`submitPlan()` implicit
Vote	`ConsensusVote` interface	`approvePlan` / `rejectPlan`
Threshold	`threshold: number` (0.66 default)	`requiredApprovals`
Algorithms	`raft`, `byzantine`, `gossip`, `paxos`	Implicit majority
Result	`ConsensusResult`	Plan `status: 'approved' \| 'rejected'`

SPTFlo V3 (types.ts:197-235):

typescript

export type ConsensusAlgorithm = 'raft' | 'byzantine' | 'gossip' | 'paxos';

export interface ConsensusConfig {
  algorithm: ConsensusAlgorithm;
  threshold: number;
  timeoutMs: number;
  maxRounds: number;
  requireQuorum: boolean;
}

export interface ConsensusProposal {
  id: string;
  proposerId: string;
  value: unknown;
  term: number;
  timestamp: Date;
  votes: Map<string, ConsensusVote>;
  status: 'pending' | 'accepted' | 'rejected' | 'expired';
}

export interface ConsensusVote {
  voterId: string;
  approve: boolean;
  confidence: number;
  timestamp: Date;
  reason?: string;
}

TeammateTool (from binary):

"approvePlan" (12 refs)
"rejectPlan" (13 refs)
"requestShutdown" (14 refs) → Needs approval
"approveShutdown" (9 refs)
"rejectJoin" (11 refs)
"approveJoin" (12 refs)

4.2 Plan Mode / Swarm Launch

SPTFlo V3:

typescript

// Queen analyzes task and creates plan
const analysis = await queen.analyzeTask(task);
// Plan decomposed into subtasks
const subtasks = analysis.subtasks;
// Consensus on execution
const result = await coordinator.proposeConsensus(subtasks);
// Execute after approval
if (result.approved) {
  await coordinator.executePlan(subtasks);
}

TeammateTool (sdk-tools.d.ts:131-170):

typescript

interface ExitPlanModeInput {
  allowedPrompts?: { tool: "Bash"; prompt: string }[];
  pushToRemote?: boolean;
  launchSwarm?: boolean;      // ← Launch multi-agent execution
  teammateCount?: number;     // ← How many teammates to spawn
}

5. Join/Leave Workflows

5.1 Agent Lifecycle

Action	SPTFlo V3	TeammateTool
Register	`registerAgent(agent)`	`requestJoin` + approval
Join Approval	Implicit (no approval needed)	`approveJoin` / `rejectJoin`
Unregister	`unregisterAgent(agentId)`	`requestShutdown` + approval
Leave Approval	Implicit	`approveShutdown` / `rejectShutdown`
Force Remove	`removeNode(agentId)`	`cleanup()`

SPTFlo V3 (types.ts:519-535):

typescript

export interface IUnifiedSwarmCoordinator {
  // Agent management
  registerAgent(agent: Omit<AgentState, 'id'>): Promise<string>;
  unregisterAgent(agentId: string): Promise<void>;
  getAgent(agentId: string): AgentState | undefined;
  getAllAgents(): AgentState[];
  // ...
}

TeammateTool operations:

requestJoin (13 refs) → Agent wants to join team
approveJoin (12 refs) → Coordinator approves
rejectJoin (11 refs) → Coordinator rejects
requestShutdown (14 refs) → Agent wants to leave
approveShutdown (9 refs) → Coordinator approves shutdown
rejectShutdown → Coordinator rejects (implicit)

6. Spawn Backends

6.1 Execution Environments

Backend	SPTFlo V3	TeammateTool
In-Process	Default (same process)	`in_process_teammate` (18 refs)
tmux	Via Bash tool	`tmux` (26 refs) + env vars
Background	`run_in_background: true`	Same parameter
iTerm2	Not implemented	Suspected (macOS)

SPTFlo V3 approach:

Agents run as sub-processes via Claude Code Task tool
Background execution via run_in_background: true
Coordination via MCP + memory

TeammateTool environment variables:

bash

CLAUDE_CODE_TMUX_SESSION       # tmux session name
CLAUDE_CODE_TMUX_PREFIX        # tmux prefix key
CLAUDE_CODE_TEAMMATE_COMMAND   # Spawn command

7. Side-by-Side Code Comparison

7.1 Creating a Team/Swarm

SPTFlo V3:

typescript

import { UnifiedSwarmCoordinator } from '@sptflo/swarm';

const coordinator = new UnifiedSwarmCoordinator({
  topology: { type: 'hierarchical', maxAgents: 8 },
  consensus: { algorithm: 'raft', threshold: 0.66 },
});

await coordinator.initialize();

// Register agents
await coordinator.registerAgent({
  name: 'coder-1',
  type: 'coder',
  capabilities: { codeGeneration: true, languages: ['typescript'] }
});

TeammateTool:

typescript

// Via AgentInput to Task tool
Task({
  description: "Spawn coder",
  prompt: "You are a TypeScript coder...",
  subagent_type: "coder",
  name: "coder-1",
  team_name: "dev-team",
  allowed_tools: ["Edit", "Write", "Read"],
  mode: "default"
});

7.2 Broadcasting a Message

SPTFlo V3:

typescript

await coordinator.broadcastMessage({
  type: 'task_assign',
  payload: { taskId: 'task-123', description: 'Implement feature' }
}, 'high');

TeammateTool:

typescript

// Via TeammateTool.broadcast operation
TeammateTool.broadcast({
  from: 'coordinator',
  type: 'task',
  payload: { taskId: 'task-123', description: 'Implement feature' }
});

7.3 Plan Approval

SPTFlo V3:

typescript

const proposal = await coordinator.proposeConsensus({
  plan: 'Implement authentication',
  steps: ['Create models', 'Add endpoints', 'Write tests']
});

// Agents vote
await consensusEngine.vote(proposal.id, {
  voterId: 'coder-1',
  approve: true,
  confidence: 0.9
});

const result = await consensusEngine.awaitConsensus(proposal.id);
if (result.approved) {
  // Execute plan
}

TeammateTool:

typescript

// Coordinator submits plan, teammates vote
// Then launch swarm with ExitPlanModeInput
ExitPlanMode({
  launchSwarm: true,
  teammateCount: 4,
  allowedPrompts: [
    { tool: 'Bash', prompt: 'Create models' },
    { tool: 'Bash', prompt: 'Add endpoints' },
    { tool: 'Bash', prompt: 'Write tests' }
  ]
});

Message Bus - broadcast, direct send, acknowledgment
Plan Approval - propose → vote → execute
Join/Leave - request + approval workflow
Spawn Backends - in-process, tmux, background

Terminology Mapping

SPTFlo V3	TeammateTool
Swarm	Team
Agent	Teammate
Queen/Coordinator	Plan mode agent
MessageBus	Mailbox
ConsensusProposal	Plan
ConsensusVote	approvePlan/rejectPlan
