SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Coordinate inter-agent messaging across multiple A2A-enabled agents.

Core Features & Use Cases

  • Supports sending, replying, prioritizing, and tracking history across agents using the Synapse A2A protocol.
  • Provides a central reference for commands, task flows, and safety checks to coordinate multi-agent work.
  • Real-world scenario: coordinate a cross-agent debugging session with messages, replies, and task history lookup.

Quick Start

List agents with synapse list and then send a message with synapse send to a target using the --from flag.

Frequently Asked Questions about synapse-a2a

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I coordinate inter-agent messaging across multiple agents?▼

To coordinate inter-agent messaging, use the Synapse A2A protocol to send, reply, prioritize, and track message history across A2A-enabled agents. You can orchestrate complex multi-agent workflows by applying task flows and safety checks from a central reference.

What is the Synapse A2A protocol used for in multi-agent workflows?▼

The Synapse A2A protocol is used for inter-agent communication, enabling agents to send messages, reply to tasks, prioritize operations, and trace history. It provides a structured way to coordinate cross-agent debugging and multi-agent task execution.

How do I send a message to a specific agent using A2A?▼

To send an inter-agent message, first list available agents using the synapse list command, then use synapse send with the --from flag to specify the sender and target the desired receiving agent for message delivery.

Can I trace task history and perform file-safety checks during multi-agent communication?▼

Yes, you can trace task history and perform file-safety checks during multi-agent communication. The Synapse A2A workflow includes history lookup and file-safety validation to ensure secure and trackable cross-agent messaging operations.

Do I need specific dependencies to run A2A inter-agent messaging?▼

No external dependencies are required to run A2A inter-agent messaging. The system relies on a SKILL.md frontmatter with name and description, a Markdown body for operational instructions, and optional scripts, references, and assets for on-demand resources.

What are the limitations of using Synapse A2A for cross-agent debugging?▼

Synapse A2A is specifically designed for A2A-enabled agents, meaning non-A2A agents cannot participate in the inter-agent messaging workflow. Coordination is limited to agents supporting the Synapse protocol for sending, replying, and history tracking.
