Swarm Communication Skill

Overview

This skill allows you to communicate with and control other agents in the swarm using a decentralized, file-based messaging system.

Communication Protocol

You communicate by writing JSON files to your output/ directory and reading files from your incoming/ directory.

1. Sending a Request

To send a message to a sub-agent, create a JSON file in your output/ directory: output/to_[target]_[unique_id].json

Atomicity Rule: You MUST write the file with a .tmp extension first (e.g., to_orchestrator_123.tmp) and then rename it to .json when the write is complete!

JSON Schema:

{
  "request_id": "req_123",
  "type": "prompt",
  "sender": "master",
  "target_agent": "orchestrator",
  "prompt": "Your instructions to the agent here."
}
  • request_id: A unique identifier for the request.
  • type: Must be "prompt" for sending instructions.
  • sender: MUST be "master"!
  • target_agent: MUST be "orchestrator"! (Master can only trigger Orchestrator).
  • prompt: The text message or command you want the agent to execute.

2. Reading a Response

The background Orchestrator will pick up your request, route it, and the response from the target will be placed in your incoming/ folder as from_orchestrator_[original_name].json. You should wait for the notification or poll your incoming/ folder.

Communication Boundaries Rules

As the Master Agent, you are subject to strict communication boundaries enforced by the system:

  1. You can only trigger the Orchestrator Agent (target_agent: "orchestrator"). You cannot target sub-agents directly.
  2. You can only be triggered by the Orchestrator Agent. Do not accept tasks from sub-agents.

Payload Content Rules

When sending a response or request, ensure the prompt or output field contains ONLY the relevant information. You MUST wrap your final answer in ===RESULT=== and ===END_RESULT=== markers (e.g., in the output field or terminal output). The system will extract content between these markers to remove UI garbage.

Completion Rule

When you complete an assigned task or require upper layer attention, you MUST write a response file to your output/ directory (following the Atomicity Rule) to inform the upper layer. Failure to do so will leave the system waiting indefinitely!
