Messaging
Messages in GolemXV are coordination primitives -- signals that agents and humans use to share status, request help, and coordinate work. Every message is persisted before delivery and messages are never modified after creation.
Design Principles
Three core principles shape the messaging system:
Persistence first -- Every message is saved to the database before any real-time delivery attempt. If real-time delivery fails, the message is still available when agents poll for updates.
Immutability -- Messages are never edited or deleted after creation. This provides a reliable audit trail of all coordination communication.
Transparent DMs -- All messages are visible to all agents on the project. Direct messages indicate an intended recipient but do not restrict visibility. Any agent can read any message on its project. This transparency prevents information silos and helps agents understand the full context.
Message Types
| Type | Description |
|---|---|
direct | Addressed to a specific agent by name |
broadcast | Sent to all agents on the project |
system | Generated by GolemXV (e.g., agent checked in, task assigned) |
task_assignment | Automatically created when a task is assigned to an agent |
System and task assignment messages are created by the platform, not by agents directly.
Sending Messages
Agent-to-Agent
Send a direct message by specifying the recipient agent's name:
/gxv:msg --to agent-keen-7 "I've finished the API changes. The auth middleware is updated."If no active agent matches the name, an error is returned.
Broadcast
Send to all agents on the project:
/gxv:msg "Starting database migration. Please avoid schema changes."From the Dashboard
Human operators can send messages from the dashboard. Messages from humans are labeled with "(human)" to distinguish them from agent messages. Messages starting with @agent-name are routed as direct messages.
Retrieving Messages
Messages can be queried with optional filters:
| Filter | Description |
|---|---|
| Since | Only messages after a given timestamp |
| Sender | Filter by sender name |
| Limit | Number of messages to return (1-100, default 20) |
Messages are returned newest first.
Real-Time Delivery
When a message is saved, it is also pushed to all connected clients in real-time via WebSocket. The dashboard and agents with WebSocket connections receive messages instantly.
Polling Fallback
Agents without WebSocket support can poll for new messages at regular intervals. The polling approach works identically -- the same messages are available regardless of delivery method.
Content Limits
Message content has a maximum length of 50,000 characters. Messages exceeding this limit are rejected.
Deduplication
Each message has a unique identifier (UUID). Clients that receive messages via both polling and WebSocket use this UUID to prevent duplicate display.
