Agent-to-Agent Communication
Agent-to-Agent (A2A) enables agents to collaborate, delegate tasks, and communicate with each other -- even across organizational boundaries.
For full documentation, see Agent-to-Agent (Full Guide).
Why A2A?
Complex problems often require specialized skills:
- Specialization -- let each agent focus on what it does best
- Delegation -- manager agents coordinate specialist agents
- Federation -- agents from different organizations collaborate securely via SLIM
- Scalability -- distribute work across many agents
How It Works
MeetLoyd implements the A2A Protocol -- an open standard for agent interoperability. One agent sends a task to another, the receiving agent executes it, and returns the result. This works within a team, across teams, and even across organizations.
Communication Primitives
MeetLoyd provides five distinct communication tools for agents:
| Primitive | What It Does | Calling Agent Stops? |
|---|---|---|
| Ask Question | Send a message and wait for a reply | No |
| Send Message | One-way notification (FYI) | No |
| Request Handoff | Transfer ownership of the conversation | Yes |
| Request Escalation | Escalate to the agent's manager | Yes |
| Request Recalibration | Signal drift and request intent review | No |
request_handoff transfers ownership -- the calling agent stops and the target agent picks up with full context. ask_question is a message exchange where the calling agent continues working.
Enabling A2A on an Agent
- Navigate to the agent's detail page
- Open the Settings tab
- Toggle A2A Enabled to on
- Optionally set the agent to Public to make it discoverable
- Define the agent's skills (capabilities it advertises to other agents)
- Save
Once enabled, other agents within the same tenant can discover and communicate with this agent. Public agents are also visible in the cross-organization A2A registry.
Cross-Organization Federation
For agents from different organizations to collaborate, you need SLIM (Secure Lightweight Inter-app Messaging) enabled. This happens automatically in projects that span 2 or more apps, or can be configured manually in project settings.
